Payroll processing in a medical practice is more complicated than in most other industries. Clinical staff work varying schedules, locum tenens providers move between facilities, and compensation structures often include fixed salaries, hourly rates, overtime, and performance bonuses running in parallel. For a practice manager trying to keep up with IRS obligations while ensuring staff are paid accurately and on time, the stakes are high.

Understanding what are the 4 types of payroll systems is the starting point for making the right choice. Each model carries different implications for cost, compliance, and operational control.

This guide breaks down manual in-house payroll, payroll software, outsourced payroll services, and Professional Employer Organizations (PEO), with a specific focus on how each option holds up against the realities of running a US healthcare practice. If you are currently evaluating your options or looking to replace an outdated process, you will find a clear framework here for making that decision.

What Are the 4 Types of Payroll Systems? A Quick Overview

Before diving into each model in detail, here is a quick reference summary of the four types of payroll systems. Understanding these categories is the foundation for every HR and payroll systems decision a practice manager will make.

Payroll System TypeBest ForKey StrengthMain Risk
Manual (In-House)Very small, simple practicesFull control, low costError-prone, compliance risk
Payroll SoftwareGrowing small to mid-size practicesAutomation, scalabilityRequires setup and training
Outsourced PayrollPractices wanting hands-off processingTax compliance expertiseLess visibility and control
Professional Employer Organization (PEO)Practices seeking full HR supportBenefits access, co-employmentHigher cost, shared employer status

Each of the four types of payroll systems in HRM addresses a different balance between cost, control, and compliance. The sections below examine each in depth, with healthcare-specific considerations throughout.

1. Manual Payroll Processing (In-House)

Manual payroll, also called in-house payroll, refers to the practice of calculating employee wages, tax deductions, and net pay using spreadsheets, paper records, or basic accounting tools, without dedicated payroll software. It is the oldest of the types of payroll in HR and remains in use primarily among very small or newly established practices.

For very small practices with just one or two staff members and straightforward compensation arrangements, this approach can be viable. It requires no software subscription costs and gives the practice owner direct supervision over every calculation and payment.

However, the limitations become significant quickly. Manual payroll is highly susceptible to errors, including miscalculated deductions, incorrect overtime rates, and missed tax filing deadlines. In a healthcare environment, wage calculations grow complex fast. A practice employing nurses on varying schedules, a part-time medical assistant, and a salaried physician will struggle to manage those varied pay structures reliably using manual methods.

  • From a compliance standpoint, the risks are substantial. US employers are required to withhold and deposit federal income tax, Social Security, and Medicare taxes accurately and on schedule. Errors in payroll taxes can trigger IRS penalties, and manually tracking regulatory changes, such as updates to FICA rates or state-level withholding requirements, is an ongoing burden.
  • A payroll manager handling this manually must stay current with all relevant rules, including federal and state income tax withholdings, without the automated alerts that software solutions provide.
  • There are also practical limitations around time and documentation. Generating accurate payslips, maintaining payroll records for audits, and reconciling payroll data with accounting entries all take significantly longer when done by hand.

In summary, while manual payroll offers low upfront cost and direct control, the risk of errors and the complexity of healthcare-specific wage calculations make it a poor fit for most practices beyond the smallest single-provider settings.

Pros of Manual In-House Payroll

  • Zero software subscription cost
  • Full direct supervision of every calculation
  • Simple to operate for a single-provider practice with one pay structure

Cons of Manual In-House Payroll

  • High exposure to errors and missed tax filings
  • Cannot scale with staff growth or complex shift structures
  • No automated tax compliance updates or alerts
  • Generating payslips and audit records is time-consuming

2. Payroll Software Solutions

Payroll software is currently the most widely adopted solution among small and mid-size healthcare practices. These platforms automate the core payroll processing cycle, from calculating gross pay and deductions to filing payroll taxes and issuing direct deposit payments. Cloud-based payroll systems have become the standard, allowing practice managers to run payroll from any location without relying on locally installed software.

The core advantages of automated payroll include reduced manual effort, fewer payroll errors, and built-in tax compliance tools. Most platforms automatically calculate and file federal and state payroll taxes, generate W-2 and 1099 forms, and keep records audit-ready.

This is a significant improvement over manual methods, particularly for tax filings, where errors carry direct financial penalties.

For healthcare practices, the most valuable feature is integration. When payroll software connects directly with healthcare scheduling software systems, actual hours worked can flow into payroll automatically, reducing the risk of discrepancies between scheduled and paid hours. This is especially relevant for practices managing nursing staff on rotating rosters, where time and attendance data must be captured precisely to calculate correct pay.

  • Cloud-based payroll platforms also typically offer employee self-service portals, where staff can access their payslips, update banking details for direct deposit, and review their time and attendance records. This reduces the administrative workload on the practice manager and improves employee satisfaction by giving staff transparency over their pay.
  • From a data security standpoint, reputable cloud-based payroll providers invest in encryption, access controls, and compliance with HIPAA-adjacent data handling standards. Storing payroll data in a secure cloud environment is generally safer than maintaining local spreadsheets or on-premise files that can be lost or accessed without authorization.
  • Scalability is another clear advantage. As a practice grows from three staff members to fifteen, or expands to a second location, payroll software scales with the business. Adding employees, adjusting pay structures, or managing multi-state tax obligations becomes manageable within the same platform rather than requiring an entirely new system.

This scalability, combined with the integration capabilities of modern platforms, is why payroll software consistently ranks as the top choice in types of payroll software comparisons published by reviewers such as G2.

Well-known platforms used in healthcare settings include Gusto, ADP, QuickBooks Payroll, and Paycor, each offering different feature sets around automation, reporting, and integration. When evaluating these platforms, compliance with the FLSA (Fair Labor Standards Act) is just as critical as IRS compliance. The right software automatically tracks hours worked and applies overtime rules correctly, keeping your practice aligned with federal labor laws.

quickbooks-interface

Medesk, for example, automatically tracks doctors' working hours, generates reports on amounts paid and days worked, and allows practices to split pay into fixed and bonus components. This rostering integration means the data flowing into payroll calculations reflects actual clinical activity, not just scheduled hours.

Pros of Payroll Software

  • Automated payroll processing reduces errors and saves time
  • Built-in tax compliance and automatic payroll tax filing
  • Cloud-based payroll enables remote access and data security
  • Employee self-service improves employee satisfaction
  • Scalability supports practice growth without switching platforms
  • Integration with scheduling systems eliminates manual data re-entry

Cons of Payroll Software

  • Requires initial implementation, configuration, and staff training
  • Monthly subscription cost, though typically lower than outsourced or PEO models
  • Healthcare-specific features (shift differentials, locum payroll) vary by platform

3. Outsourced Payroll Services

Outsourced payroll involves contracting a third-party provider to handle all aspects of payroll processing on behalf of the practice. The external agency manages wage calculations, generates payslips, handles direct deposit, and takes responsibility for tax filings and regulatory compliance.

The primary appeal of outsourced payroll is removing the compliance burden from internal staff. A specialist payroll bureau stays current with IRS regulations, state tax law changes, and federal and state income tax withholdings. They assume responsibility for accurate and timely submissions.

For practice owners who do not have a dedicated HR function, this can represent meaningful cost savings compared to hiring a full-time payroll specialist.

Outsourced payroll providers typically operate under service-level agreements (SLAs) that specify turnaround times, accuracy guarantees, and support availability. These SLAs give the practice a formal framework for holding the provider accountable. When a payroll error does occur, the provider is contractually obligated to resolve it within a defined timeframe.

The trade-off is visibility. When payroll processing sits with a third party, the practice manager has less direct oversight of day-to-day calculations. Any queries from staff about their pay, deductions, or payslips may require routing through the external provider, which can slow resolution times.

For healthcare practices with complex pay structures, including shift premiums or variable hours, communicating the correct inputs to an external team every payroll cycle requires a reliable and well-documented data handover process.

Outsourced payroll can also become costly as staff numbers grow, since most providers charge per payslip or per employee processed. At a certain scale, switching to dedicated payroll software or an in-house HR function may deliver better value. Research from Deloitte on HR outsourcing trends consistently highlights this tipping point as a key decision factor for growing organizations.

That said, for a small practice without internal payroll expertise, outsourcing is a practical middle ground. It delivers tax compliance and administrative relief without the full financial commitment of a PEO arrangement.

The cost-per-employee economics of outsourcing typically favor smaller practices. As headcount grows past a certain point, the per-payslip fees and data coordination overhead can make bringing payroll back in-house, or switching to software, a more cost-effective choice.

Employee vs Independent Contractor: Why Classification Matters for Healthcare Payroll

One of the most consequential payroll decisions a US medical practice makes is how it classifies clinical staff. Correctly classifying employees and independent contractors for payroll purposes determines whether FICA taxes must be withheld, whether a W-2 or 1099 form is issued at year end, and whether the practice owes employer-side payroll taxes.

For healthcare practices, this question arises most often with locum tenens providers, per-diem nurses, and contracted therapists. A locum physician engaged through an agency, working a defined set of shifts, and free to take assignments elsewhere may qualify as an independent contractor under IRS criteria. A nurse practitioner who works regular hours under direct clinical supervision, uses practice equipment, and has no independent patient panel is almost certainly an employee.

Getting this wrong has real consequences. The IRS and the Department of Labor (DOL) both enforce worker classification rules, and misclassification can result in back taxes, penalties, and interest covering the period of the error. The DOL's economic reality test and the IRS common-law control test both examine the degree of behavioral and financial control the practice exercises over the worker.

When evaluating payroll systems, confirm that your chosen solution can handle both W-2 employee payroll and 1099 contractor payments within the same platform, and that it supports the correct tax forms for each. Outsourced payroll providers and PEOs typically include classification guidance as part of their compliance service. Software platforms vary: some include built-in 1099 workflows, while others require a separate contractor payment process.

Pros of Outsourced Payroll

  • Tax compliance managed by specialists with up-to-date regulatory knowledge
  • Reduces internal administrative burden significantly
  • Formal service-level agreements provide accountability
  • Cost savings versus hiring a dedicated payroll manager

Cons of Outsourced Payroll

  • Reduced direct visibility over payroll calculations
  • Per-payslip pricing can become expensive at scale
  • Complex healthcare-specific inputs require disciplined data handover
  • Less integration with internal rostering or scheduling systems

4. Professional Employer Organizations (PEO)

A Professional Employer Organization (PEO) enters into a co-employment arrangement with the medical practice. In this model, the PEO becomes the employer of record for the practice's staff, taking on responsibility for payroll processing, payroll taxes, benefits administration, HR compliance, and workers' compensation.

For a growing small business medical practice, the co-employment model offers access to benefits packages that would otherwise only be available to much larger organizations. Because the PEO pools employees from multiple client companies, it can negotiate group health insurance rates, retirement plans, and other benefits that a small clinic could not access independently. This is a meaningful lever for employee satisfaction and recruitment in a competitive healthcare labor market.

The PEO handles tax filings, federal and state income tax withholdings, and regulatory reporting across all relevant jurisdictions. For multi-state practices or those operating in areas with complex local tax requirements, this coverage is particularly valuable. The arrangement also provides a layer of financial stability, since the PEO assumes shared liability for employment compliance obligations.

Co-employment implications. When a practice enters a PEO arrangement, the co-employment structure means the PEO is the legal employer for tax and benefits purposes, while the practice retains day-to-day operational control over clinical staff. This shared employer status has practical consequences: the PEO sets the HR policies and benefits framework, and the practice must operate within those parameters. For most administrative functions this is seamless, but practices with highly customized compensation structures or unusual benefit arrangements may find the PEO's standardized approach does not accommodate every requirement.

IRS-certified PEO status. The IRS operates a Certified Professional Employer Organization (CPEO) program. A CPEO has met specific financial, reporting, and background standards set by the IRS. Working with a CPEO carries additional legal protections around tax liability. If the PEO fails to remit payroll taxes, a CPEO client practice retains certain statutory protections that non-certified PEO clients do not. For a small healthcare practice, this distinction is worth verifying before signing a PEO contract.

Benefits pooling for small practices. One of the most practical reasons a small medical practice considers a PEO is access to group health insurance rates it could not negotiate independently. A five-provider practice cannot command favorable premiums from insurers. A PEO representing thousands of employees across many client companies can, and it passes those rates through to client practices. This can make the PEO's fee effectively self-funding if the savings on benefits premiums are large enough.

However, the co-employment structure does mean the practice gives up some direct control over HR processes. The PEO's standardized HR services may not accommodate highly customized compensation structures, which can be a limitation for practices using incentive-based pay, production bonuses for physicians, or complex shift differential arrangements.

PEO services are also among the more expensive payroll models, typically priced as a percentage of total payroll or as a per-employee monthly fee. For a small practice with tight margins, this cost must be weighed carefully against the administrative relief and benefits access the arrangement provides.

Exiting a PEO. Leaving a PEO is more operationally complex than switching between payroll software platforms. When a practice exits, it must re-establish its own benefits contracts, reissue employee benefit elections, transfer payroll tax accounts back to its own EIN, and ensure continuity of workers' compensation coverage. Many PEO agreements include a notice period of 30 to 90 days. Planning the exit well in advance, ideally at a natural contract renewal point and outside of open enrollment periods, reduces disruption to staff.

A PEO is most likely to suit a practice in a growth phase that is adding staff quickly and needs comprehensive HR services without building an internal HR department from scratch. Practices with highly specialized compensation structures or strong in-house HR capabilities may find the model too rigid.

Pros of PEO

  • Full payroll processing, payroll taxes, and HR compliance managed externally
  • Access to large-group benefits rates that small practices cannot negotiate independently
  • Supports financial stability by sharing employment compliance liability
  • Scalability across multiple states and employee categories
  • IRS-certified PEO status provides additional tax liability protections

Cons of PEO

  • Highest cost among the four payroll system types
  • Co-employment arrangement reduces direct employer control
  • May lack flexibility for complex healthcare compensation structures
  • Exiting a PEO arrangement requires careful transition planning and advance notice

Payroll Compliance Essentials for US Medical Practices

Payroll compliance in a US medical practice is not a single obligation. It is a set of overlapping federal and state requirements that must all be met correctly, on time, every pay cycle. Missing one layer can trigger penalties that accumulate quickly.

The following checklist covers the core federal obligations every US medical practice must manage, regardless of which payroll system type it uses.

FLSA Overtime Rules The Fair Labor Standards Act requires employers to pay non-exempt employees at least 1.5 times their regular rate for hours worked beyond 40 in a workweek. In a healthcare setting, this applies to hourly nursing staff, medical assistants, and other non-exempt clinical support roles. Physicians and certain advanced practice providers may qualify for the FLSA's learned professional exemption, but this must be evaluated based on actual job duties and salary level, not just job title.

FICA Withholding The Federal Insurance Contributions Act requires employers to withhold Social Security and Medicare taxes from each employee's wages and to contribute an equal matching amount from the employer side. Both the employee and employer portions must be deposited with the IRS on a schedule determined by the practice's total payroll tax liability. Practices that deposit late face percentage-based penalties that increase with the duration of the delay.

W-2 vs 1099 Classification As covered in the classification section above, correctly distinguishing employees from independent contractors determines the entire tax treatment of a worker. W-2 employees require FICA withholding and employer matching. 1099 independent contractors handle their own self-employment taxes, and the practice issues a 1099-NEC form rather than withholding. For locum tenens providers, per-diem nurses, and contracted therapists, this classification must be made correctly before the first payment is issued, not retrospectively.

Federal Tax Deposit Schedules The IRS assigns each employer to either a monthly or semi-weekly deposit schedule for federal payroll taxes, based on the prior-period lookback of total taxes reported. Most small and mid-size practices fall on the monthly schedule initially, but as payroll grows, the schedule may shift to semi-weekly. Missing a deposit deadline triggers a failure-to-deposit penalty. Payroll software and outsourced providers typically manage deposit scheduling automatically. Manual payroll processors must track and meet these deadlines independently.

State-Level Obligations Every state has its own income tax withholding rules, deposit schedules, and unemployment insurance requirements. Multi-state practices face the added complexity of determining which state's withholding applies for employees who work across state lines. State unemployment insurance (SUI) rates vary by employer experience rating and must be reconciled and paid separately from federal obligations.

Year-End Reporting W-2 forms for all employees and 1099-NEC forms for qualifying contractors must be issued by January 31 each year. Copies must also be filed with the Social Security Administration and relevant state agencies. Errors on year-end forms generate correction requirements (W-2c) and can delay employee tax filings.

Maintaining a compliance calendar that tracks all federal and state deposit deadlines, filing dates, and reporting obligations is the single most effective administrative habit a small practice can develop, regardless of which payroll system model it uses.

How to Choose the Right Payroll System for Your Practice

The comparison above outlines the structural differences between the four payroll systems. But choosing the right one for a healthcare practice requires applying those differences to the specific operational context of clinical environments.

When asking what are the 4 types of payroll systems that best fit a medical setting, the answer depends heavily on factors like practice size, staff composition, integration requirements, and compliance risk tolerance.

Practice Size and Provider Count

The number of providers and support staff in a practice is the starting point for any payroll system evaluation. A solo practitioner with two administrative staff has fundamentally different payroll complexity than a six-provider multi-specialty group with rotating nursing staff and a mix of employed and contracted clinicians. Manual payroll becomes unworkable once complexity passes a certain threshold. Payroll software scales comfortably from two employees to fifty or more. Outsourced payroll and PEO arrangements are typically most cost-effective at ten or more employees, where the per-employee fee represents a reasonable proportion of the administrative value delivered.

Staff Mix: W-2 Employees and 1099 Contractors

Healthcare practices frequently employ a mix of salaried W-2 employees and 1099 independent contractors in the same clinical operation. A practice with four employed nurses, two contracted locum physicians, and a part-time physical therapist on a per-session basis needs a payroll system that handles all three compensation structures cleanly. Not every platform does this equally well. Before selecting a system, verify how it handles 1099 payments, contractor payment records, and year-end 1099-NEC generation alongside standard W-2 payroll.

Multi-Location Needs

Practices operating across more than one site introduce multi-location payroll complexity. Staff may work at different locations on different days, affecting which state's tax rules apply and how time and attendance data is collected. Payroll software with multi-location support, or an outsourced provider experienced in multi-site healthcare, handles this more reliably than a single-location tool stretched beyond its design.

Integration with Scheduling and EHR Systems

Payroll does not exist in isolation. The hours recorded in a scheduling system, the shift differentials assigned to specific rosters, and the clinical activity tracked in an EHR all feed into accurate compensation calculations. A payroll system that does not connect with clinical scheduling creates a manual data bridge that introduces both error and administrative time. When evaluating platforms, prioritize those with direct integration to your scheduling system, or those that support data export in a format your scheduling tool can receive.

Choosing a Pay Frequency

Deciding how often to run payroll is a practical dimension of system choice that many practices underestimate. Weekly pay increases administrative workload and cash flow pressure but improves employee satisfaction, particularly for hourly nursing staff managing tight personal budgets. Biweekly pay (every two weeks, 26 pay periods per year) is the most common choice for small healthcare practices because it balances regularity with manageable processing overhead. Semi-monthly pay (twice per month, 24 pay periods per year) aligns more neatly with monthly billing cycles and is common in practices where most staff are on fixed salaries. Monthly pay is rare in US healthcare settings and tends to create staff satisfaction issues.

Your payroll software or provider must support your chosen frequency without additional configuration cost. Some outsourced providers charge per payroll run, meaning weekly pay costs more than biweekly. Factor pay frequency into the total cost comparison when evaluating options.

Compliance Risk Tolerance

A practice that has previously received IRS penalty notices, operates in a state with complex withholding rules, or employs staff across multiple states should weight compliance capability heavily. In those circumstances, the additional cost of outsourced payroll or a PEO may be justified purely by the reduction in compliance exposure. A stable single-state practice with simple pay structures carries lower compliance risk and can get full value from a well-configured software platform.

Here is a side-by-side comparison to help narrow down the options:

Locum tenens payrollDifficult to managePossible with configurationRequires clear SLAsSupported
Rostering integrationNoneAvailable in specialist toolsUnlikelyUnlikely
ScalabilityPoorStrongModerateStrong
Cost for small practiceLowModerateModerateHigh
Employee self-serviceNoYesLimitedYes

Two payroll challenges that generic guides consistently underweight are shift differentials and locum tenens payroll:

  1. Healthcare practices running 24-hour or extended-hour rosters must calculate pay premiums accurately for evening, overnight, and weekend shifts.
  2. A nurse working a standard day shift earns a different effective rate than one covering a Saturday night on-call.

Without a payroll system that can handle these shift differentials automatically, the payroll manager must apply them manually every pay cycle, which introduces both error risk and significant administrative time.

Locum tenens payroll adds further complexity. Locum providers are often paid on a per-session or per-day basis, may work across multiple sites, and are sometimes classed differently for tax purposes depending on whether they are engaged as employees or independent contractors. A payroll system that cannot distinguish between these categories cleanly will create compliance exposure.

Rostering integration is the operational solution to both of these problems. When the system tracking who is scheduled, who actually worked, and which shift category applies flows directly into payroll calculations, the risk of manual error drops substantially. Practices using Medesk benefit from this kind of integrated approach, where scheduling data informs pay calculations rather than requiring a separate data entry step.

For practices also looking to improve financial oversight, medical reporting software that tracks payroll alongside clinical activity data allows managers to monitor labor costs relative to revenue in real time. This level of reporting is particularly useful for practices managing multiple providers or locations.

If you are also exploring broader staff management tools, reviewing available care management software options can help you understand how payroll fits within a wider clinical operations stack.

How to Switch Payroll Systems Without Disrupting Your Practice

Switching payroll systems is one of those decisions that most practice managers delay too long because the transition feels risky. A poorly timed or poorly planned payroll system transition can result in missed pay runs, incorrect tax filings, or confused staff. Done carefully, it is far less disruptive than staying on a system that no longer fits the practice.

Step 1: Audit Your Current Payroll Data

Before migrating to any new system, compile a clean export of all current payroll data. This includes employee records, pay rates, tax withholding elections (W-4 data), direct deposit banking details, year-to-date earnings, and year-to-date tax withholdings. Incomplete data migration is the most common source of errors in the first payroll run on a new system. Most payroll software platforms accept imports in CSV format. Confirm the new platform's import template before exporting from your current system.

Step 2: Time the Switch Around a Payroll Cycle Boundary

The least disruptive time to switch payroll systems is at the start of a new payroll year (January 1) or at the start of a new quarter. Starting at a year boundary means year-to-date tax figures begin at zero in both the old and new systems, eliminating the need to reconcile partial-year figures. A mid-year switch is workable but requires careful reconciliation of year-to-date figures to ensure W-2s are accurate at year end. If a mid-year switch is unavoidable, cut over at the start of a pay period, not mid-cycle. Running a parallel payroll, processing one full cycle in both the old and new systems simultaneously before fully cutting over, gives you a reconciliation check before the transition becomes permanent.

Step 3: Communicate the Change to Staff

Employees need to know that their pay process is changing, even if the amount and timing of their pay is not affected. Communicate at least two weeks before the first payroll run on the new system. Tell staff what is changing (the platform), what is not changing (their pay amount, pay date, and direct deposit details unless they need to re-enter them), and where to direct questions. If the new system includes an employee self-service portal, provide login instructions and a brief walkthrough so staff can access their own payslips and tax documents independently from day one.

Step 4: Verify Tax Account Setup

A new payroll system must be connected to the practice's federal and state tax accounts before the first payroll run. This includes the practice's Employer Identification Number (EIN), federal tax deposit schedule, and state unemployment insurance account numbers for every state where the practice has employees. Errors in tax account setup can cause deposits to be applied to the wrong account, generating penalty notices weeks later. Confirm all account numbers with your accountant or tax advisor before running the first live payroll.

Step 5: Run a Test Payroll Before Going Live

Most payroll software platforms support a test payroll run that processes calculations without submitting tax deposits or issuing payments. Use this to verify that gross pay, deductions, employer contributions, and net pay match your expectations for a representative sample of employees. Flag any discrepancies before the live run, not after.

The goal is a transition that staff never notice because their pay arrives on time and without error. With the right preparation, switching payroll systems strengthens rather than disrupts your practice's administrative operations.

Frequently Asked Questions About Payroll Systems

  1. What are the 4 types of payroll systems?

The four types of payroll systems are manual in-house payroll, payroll software, outsourced payroll services, and Professional Employer Organizations (PEO). Manual uses spreadsheets, software automates calculations and tax filings, outsourced delegates the process to a third-party provider, and a PEO handles payroll alongside broader HR services through a co-employment model.

  1. What is the best payroll system for a small medical practice?

For most small healthcare practices, cloud-based payroll software offers the best balance of cost, automation, and scalability. It reduces administrative errors, handles tax compliance automatically, and easily manages complex clinical shift schedules.

  1. How does a PEO work for healthcare practices?

A PEO enters into a co-employment agreement with your practice, becoming the employer of record for tax and benefits purposes. The PEO then handles payroll processing, tax filings, and HR compliance, while the practice maintains day-to-day control over clinical operations and staff scheduling.

  1. Can payroll software handle locum tenens providers?

Yes, modern payroll software can manage locum tenens staff by configuring the system to distinguish between independent contractors and employees. This ensures locum providers are paid correctly based on per-session or per-day rates while maintaining proper tax classification.

  1. What is the difference between payroll software and a PEO?

Payroll software (sometimes called an HRIS, HCM platform, or payroll bureau system) is a tool your practice operates directly to calculate wages, file taxes, and issue payments. The practice remains the sole employer and retains full control over HR decisions. A PEO is a service arrangement in which a third party becomes a co-employer, taking on legal responsibility for payroll taxes, benefits administration, and HR compliance alongside the practice. Software gives you control and lower cost. A PEO delivers broader HR services and benefits access, at higher cost and with shared employer status.

  1. What is the most commonly used payroll system for small medical practices?

Cloud-based payroll software is the most widely used model among small healthcare practices, with platforms such as Gusto, ADP, QuickBooks Payroll, and Paycor appearing most frequently in practice management reviews. Gusto is particularly popular with practices of under 25 employees for its ease of setup and built-in contractor payment tools. ADP and Paycor tend to be preferred as practices grow or require stronger reporting and multi-state capabilities. The right choice depends on staff mix, integration requirements, and whether the practice employs a significant number of independent contractors alongside W-2 staff.
