How To Offer Payrolling To Your Clients: A Staffing Guide

‍

Payrolling lets your staffing agency earn recurring revenue from workers your clients source themselves. This guide explains what payrolling is, how it differs from EOR and AOR, what to charge, and the steps to launch it for clients.

More companies now recruit their own contingent workers instead of relying on an agency. Even so, most of them still need someone to employ, pay, and keep those workers compliant. Learning how to offer payrolling to clients lets your agency capture that work and earn recurring revenue, even when you did not source the candidate.

The shift is real. In McKinsey's 2022 American Opportunity Survey, roughly 58 million Americans identified as independent workers, including freelancers, independent contractors, and temp workers. At the same time, more companies now source some of their own contingent workers directly rather than relying on an agency to find them.

Companies that self-source still struggle with payroll, worker classification, and multi-state compliance. Payrolling turns that struggle into a service your agency can sell. The sections below define payrolling, compare it to related models, and walk through how to price and launch it.

‍

What Are Payrolling Services?

Payrolling is the service of legally employing and paying workers a client has already sourced, then managing their taxes, benefits, and compliance. The client finds the person. Your agency, or a partner acting on its behalf, becomes the employer of record and runs everything after the hire.

Payrolling covers seasonal hires, project workers, on-call staff, and any temporary worker a client identifies directly. The defining difference from traditional staffing is the absence of recruiting. You take on employment and compliance, not sourcing.

Markups reflect that narrower scope. Across US staffing, markups run between 20 and 75 percent of pay, and payrolling sits at the lower end because you carry no sourcing cost. The rate still produces healthy margin, and it varies by role, industry, state, and the services you include.

Here is a simple example. A client sources a worker at 30 dollars per hour and asks you to payroll them. At a 30 percent markup, you bill $39 per hour and keep $9 in gross margin, with no recruiting cost to earn it.

‍

Payrolling vs EOR vs AOR

These three terms overlap, so define them clearly before you sell the service.

• Payrolling: the service of employing and paying workers a client sourced, then handling compliance.
• Employer of Record (EOR): the entity that legally employs W-2 workers and owns payroll, taxes, benefits, and workers' compensation.
• Agent of Record (AOR): the partner that engages and pays 1099 independent contractors and manages their classification and compliance.

Payrolling is the offer you make to the client. An EOR or an AOR is how you deliver it. Use an EOR model for W-2 employees and an AOR model for independent contractors, so you can support both engagement types under one relationship.

For a deeper breakdown, see our guide on how an EOR works for staffing firms. Correct classification matters, so review the differences between W-2, 1099, and C2C engagements before you onboard anyone. The IRS worker classification rules determine whether a worker is a W-2 employee or a 1099 independent contractor.

Why Staffing Agencies Should Offer Payrolling

Payrolling adds a revenue line that does not depend on winning new search assignments. It rewards the compliance and back-office skills your agency already has. The main benefits:

• Recurring revenue with no sourcing cost: you bill an ongoing markup on workers you never had to recruit.
• Client retention: you become a full workforce partner rather than only a source of temporary talent.
• Competitive edge: clients who want sourcing and payroll from one vendor will choose the agency that offers both.
• Narrower liability: your responsibility centers on compliance, not on whether the client likes a candidate's performance.

Consider a client you placed talent with last year. They now self-source similar roles and no longer need your recruiting. If you offer payrolling, you keep that account by employing and paying the workers they find, instead of losing them to a standalone platform.

How To Offer Payrolling To Your Clients

Follow these steps to launch payrolling for a client from first conversation to first payroll run.

1. Confirm the engagement model. Decide whether each worker is a W-2 employee (EOR) or a 1099 independent contractor (AOR), based on how the client directs the work.
2. Choose how you will deliver it. Build the payroll, tax, and insurance infrastructure in-house, or partner with a payrolling provider that already has it.
3. Set your pricing and markup. Agree on a markup or per-worker fee that covers employer costs and leaves margin. See the pricing section below.
4. Onboard workers and set up compliance. Collect tax forms, run background checks if required, and register for payroll tax and workers' compensation in each state of work.
5. Automate payroll, billing, and funding. Connect timekeeping, payroll, and invoicing so pay runs and client bills stay accurate and on time.
6. Launch and support the account. Run the first payroll, confirm the client's invoice, and give both the client and workers a clear point of contact.

How To Choose A Payrolling Partner

If you deliver payrolling through a partner, evaluate providers against the criteria that protect your margin and your brand:

• Compliance coverage: confirm the partner handles payroll taxes, workers' compensation, and worker classification across every state you operate in.
• Payroll funding: check whether the partner can fund payroll so you can pay workers before clients pay their invoices.
• White-label delivery: make sure the service runs under your brand, keeping your client and worker relationships yours.
• Integrations: look for prebuilt connections to your ATS and accounting tools so payroll and billing data flow without rekeying.
• Multi-state and global reach: verify support for the states and countries where your clients place workers, including local-currency payments.

For example, a healthcare client hiring travel nurses across four states needs a partner that already holds compliance and workers' compensation coverage in all four. A partner without that footprint forces you to build it yourself, which erases the margin payrolling is supposed to add.

Payrolling Pricing And Margins

Payrolling pricing usually takes one of two forms. A percentage markup adds a set percentage on top of each worker's pay and employer costs. A flat per-worker fee charges a fixed amount per worker per pay period, which suits high-wage roles where a percentage would overprice the service.

As a benchmark, US staffing markups run between 20 and 75 percent of pay. W-2 employee assignments average 50 to 60 percent, while independent-contractor assignments run closer to 30 percent, so payrolling tends to sit at the lower end, with rates varying by role, industry, state, and services included. Margin holds up because payrolling carries no recruiting or sourcing cost, so more of the markup reaches the bottom line.

Build your rate from the true cost of employment. Include employer payroll taxes, workers' compensation, benefits, funding costs, and platform fees, then add your target margin on top. Quote the client a single markup so the price stays simple to understand.

‍

Payroll Funding And Multi-State Compliance

Cash flow is the constraint that stops many agencies from scaling payrolling. You pay workers weekly, but clients often pay invoices in 30 to 60 days, creating a funding gap on every payroll run. Payroll funding closes that gap by advancing the cash to cover payroll while you wait for client payment.

Multi-state and global work adds compliance load. Each state has its own payroll tax registration, unemployment insurance, and workers' compensation rules, and each country adds employment and payment requirements. An employer of record already holds these registrations, so you can place workers in new locations without building infrastructure in each one.

Automation ties the two together. Pay and bill software with prebuilt integrations for QuickBooks, Xero, NetSuite, and common ATS platforms keeps timekeeping, payroll, and invoicing in sync. That sync reduces manual entry and billing errors as volume grows.

Frequently Asked Questions About Payrolling

‍

How much should you charge for payrolling services?
Most agencies charge a percentage markup or a flat per-worker fee. Staffing markups run between 20 and 75 percent of pay, and payrolling usually sits at the lower end because it carries no recruiting cost. Base the rate on employer taxes, workers' compensation, benefits, funding, and your target margin.

What do payrolling services cover?
Payrolling covers employment, payroll processing, tax withholding, benefits administration, workers' compensation, and compliance for workers the client sources. It does not include recruiting.

Can payrolling be white-labeled for my agency?
Yes. A white-label partner runs payroll and compliance behind the scenes while workers and clients continue to see your agency's brand.

How do you handle multi-state payroll and local taxes?
You must register for payroll tax, unemployment insurance, and workers' compensation in each state of work. An employer of record that already holds these registrations lets you skip that setup.

Do you need a special license to offer payrolling?
No federal license is required, but you must maintain state payroll tax accounts and workers' compensation coverage wherever workers are employed. Partnering with an EOR removes that requirement from your agency.

How long does it take to launch payrolling?
Timelines depend on your states of operation and whether you build in-house or use a partner. Working through an existing EOR shortens setup because the compliance infrastructure is already in place.

Start Offering Payrolling To Your Clients

Direct sourcing keeps growing, and clients who source their own workers still need a compliant employer to pay and manage them. Payrolling turns that need into recurring revenue for your agency, without recruiting costs and without diluting your brand. The path is straightforward: confirm each engagement model, set a protective markup, and deliver payroll, funding, and compliance through infrastructure built for staffing.

Ascen provides that infrastructure as a white-label EOR and AOR platform. It includes embedded payroll funding, multi-state and global compliance, and integrations for your ATS and accounting tools.
