Payroll Software for Staffing Agencies: 10 Tools Compared

A staffing agency has two payrolls, and most comparisons of payroll software for this industry write as though it has one. I build HR software for small businesses, and if an agency owner asked me where to start, I would tell them to choose software for each payroll separately. This comparison is built the same way.

Your recruiters and account managers are ordinary employees who need the same payroll any small or midsize business (SMB) runs. The workers you place at client sites need something else entirely: a system that pays them for hours worked and simultaneously invoices the client for those same hours at a different rate.

That second capability is called pay and bill, and it is the dividing line in this market. General payroll software does not have it, because a normal employer has no client to invoice. Buying Gusto or OnPay for placed workers means tracking bill rates and margins somewhere else, which works at ten placements and stops working well before a hundred.

You get 10 platforms, compared on what each one actually publishes about pricing and setup. The guide also covers two problems no payroll platform solves by itself: the cash flow gap built into staffing, and the onboarding gap that holds up placements.

Two payrolls, not one

The first decision is recognizing that you are buying for two populations with almost nothing in common operationally.

The turnover row is what drives most of the operational difference. Placed worker populations churn continuously by design, which means onboarding is not an occasional event but a continuous process running alongside payroll.

The invoicing row is what drives the software difference. Everything about a general payroll platform assumes the money flows one way: out to employees and to tax agencies. A staffing platform has to model money flowing out to workers and in from clients, derived from the same time record.

What pay and bill actually means

Pay and bill means one approved time record drives two calculations: what you pay the worker and what you invoice the client. It is the capability that separates the two categories, so understand it before you evaluate anything.

Rows four through six are the whole difference. A placed worker submits 40 hours; you pay them $22 an hour and invoice the client $34 an hour, and the margin on that placement is the spread. A general payroll platform produces the first number and knows nothing about the second.

The overtime row is a subtler trap. Client contracts frequently specify a different overtime multiplier for billing than the statutory time and a half you owe the worker, which means the pay calculation and the bill calculation diverge on the same hours. Handling that in a spreadsheet is where margin errors live.

10 platforms at a glance

With pay and bill defined, here are the platforms side by side, grouped by category. The Pay and bill column is the fastest way to tell which half of your problem a platform addresses.

Staffing-native platforms for placed workers

Four platforms built for staffing payroll are compared here, and none publishes pricing. All four are genuine implementations rather than signups.

TempWorks

TempWorks sells to staffing agencies of all sizes, with temp and contract staffing, day labor, managed service providers, and professional direct hire among the models it serves. For day labor, it lets agencies dispatch workers and issue daily checks.

The platform brings applicant tracking (ATS), customer relationship management (CRM), and pay and bill together in a single system. Multi-state tax reciprocity (for workers who live in one state and work in another) is built in, along with weekly tax filing as a service and year-end W-2 processing.

TempWorks also offers payroll funding through its sister company, Lone Oak Payroll, which addresses the cash flow problem and the software problem in one relationship. It publishes neither pricing nor an implementation timeline, so both come out of the sales process.

Avionte

Avionte markets itself as optimized for high-volume staffing such as light industrial and clerical, with tools for mass communication, shift scheduling, and redeployment. It sells the same platform to professional and multi-vertical agencies (firms staffing several industries).

For payroll and billing, Avionte supports W-2 and 1099 side by side, handles the Affordable Care Act (ACA) and the Work Opportunity Tax Credit (WOTC), and gives gross margin visibility to both recruiters and finance.

Avionte's BOLD platform also offers an open API, which lets other software connect to it, and pre-built integrations for tools such as drug screening, background checks, and credentialing. Implementation runs through an in-house team, and like TempWorks, the company publishes no timeline for it.

Bullhorn

Bullhorn is strongest as a front office (recruiting and client management): ATS and CRM depth is what agencies buy it for, with Pay and Bill built specifically for the staffing industry layered on. For an agency where recruiter productivity and candidate pipeline are the binding constraint rather than back-office throughput, that ordering is correct.

Payroll processing can run through a partner such as Greenshades, which integrates with Bullhorn in both directions, so confirm during evaluation which system pays workers and files the taxes.

Greenshades

Greenshades is a payroll, tax, and HR product rather than a full staffing platform. A two-way integration with Bullhorn and a connection to Avionte let it supply the payroll layer behind a staffing front office. Multi-state tax compliance is its strength, which matters for agencies whose placements follow client locations across state lines.

Outsourced payroll services instead of a platform

Some agencies never buy back-office software at all. Outsourced temporary staffing payroll services take the function whole: a provider processes payroll for your placed workers, remits and files the taxes, invoices your clients, and in many cases advances the money before the client pays.

The category splits two ways, which matters when you shop it. One is the outsourced back office, where the provider runs payroll and invoicing for placements you made yourself. The other is payrolling, where a client finds the worker and asks you to employ and pay them, so you carry the W-2 relationship without doing the recruiting.

The tradeoff is cost and control. Per transaction, a service is generally more expensive than software you run yourself, and part of the client billing relationship sits with somebody else.

Outsourcing suits an agency growing faster than its administrative capacity, which is also where bundled funding earns its keep. Our guide to payroll outsourcing covers the provider landscape, and employer of record covers the arrangement where the third party is the legal employer.

General payroll for your internal team

Your recruiters and account managers are ordinary W-2 employees, and most of the payroll platforms for this half of the problem publish their prices.

A ten-person internal team runs $87 to $109 a month on the platforms that publish rates, which is modest next to what a staffing-native back office involves. Choose this half on ordinary criteria: published pricing, multi-state handling, and how good the HR tooling is.

Gusto and OnPay both cost $49 plus $6 per employee, and the difference for an agency is multi-state. OnPay includes all 50 states, while Gusto Simple covers one, with multi-state payroll on the $80 plus $12 Plus tier.

State coverage matters for any agency whose recruiters work in more than one state. Patriot Full Service is the cheapest option here at $37 plus $5 per worker paid, but it adds $12 a month for each additional state.

Gusto

Gusto is the familiar default for small-business payroll, and for an agency it belongs on the internal side of the split. Simple costs $49 a month plus $6 per employee and covers one state; payroll in more than one state needs Plus, at $80 plus $12 per employee.

Signup is self-serve, with no quote to wait for. Placed workers are a different matter: Gusto has no pay and bill and raises no client invoices.

OnPay

OnPay matches Gusto's entry price, $49 a month plus $6 per worker, and includes payroll in all 50 states on that single plan, which suits an agency whose recruiters work across state lines. The per-worker fee applies only to people included in a pay run that month.

HR tools and time tracking are paid add-ons rather than part of the base price, and like every general payroll platform here, OnPay has no pay and bill for placed workers.

ADP RUN

RUN Powered by ADP sells four packages, Essential, Enhanced, Complete, and HR Pro, all by quote. Every package includes tax handling: ADP says it will calculate, file, deposit, and reconcile your payroll taxes, and that if it makes a filing error, it pays the resulting fines or penalties.

That guarantee is the compliance depth an agency buys it for, and there is no contract to sign. The price arrives only through a sales conversation, and W-2 and 1099 forms carry an additional fee.

Rippling

Rippling is modular: each HR, finance, and IT product is bought separately alongside the required Rippling Platform, and most are billed per employee per month. The pricing page is a quote form, though Rippling's own blog cites payroll at $8 per employee per month on annual billing, or $10 month to month.

For an agency that wants HR and IT on one employee record, that structure is the reason to look. The bill depends on how many products you add, so price the whole set rather than payroll alone.

Deel

Deel fits a narrower case: an agency placing contractors outside the United States. It publishes its rates, $49 per contractor per month for contractor management and $599 per employee per month for employer of record services where you have no entity abroad, and it pays out in more than 120 currencies.

An employer of record arrangement also carries a deposit of 1 to 1.5 times the monthly charges, refunded at contract end. For an agency placing only in the US, none of this applies.

When general payroll can cover placed workers too

There is a narrow case. An agency with a small number of long-term placements, no complex bill rate rules, and a willingness to track invoicing in accounting software can run everything through general payroll. OnPay in particular charges its per-worker fee only for people included in a pay run that month, which suits variable staffing volume.

That arrangement breaks on three things: placement volume beyond what a spreadsheet can track, bill rates that differ by client or by overtime rule, and any need for real-time margin visibility. Most agencies hit at least one of those well before a hundred placements.

Where staffing accounting software fits

Staffing accounting software is the third system in this stack, and most agencies meet it after buying the other two. The back office pays workers and raises client invoices. The accounting system is where those invoices become receivables, where payroll posts as a cost of services, and where gross margin per client has to hold up under review.

The overlap between the two muddles the decision. Staffing-native platforms already carry billing, receivables aging (who owes what, for how long), and margin reporting, then push a journal entry into a general ledger package. Some agencies instead run a purpose-built staffing accounting product that keeps payroll, receivables, and the ledger in one place rather than split across two vendors.

Either way, check three seams before signing. Does the platform export a journal entry mapped to your accounts, rather than a PDF summary? Does the burden on placed workers (employer taxes, workers compensation, and insurance) land with the pay, so margin reflects real cost? And are unbilled hours visible before the invoice run? The gap between work delivered and work invoiced is where staffing margin quietly leaks.

The cash flow problem no software solves by itself

The cash flow problem is built into staffing, and no platform makes it disappear. It does, however, shape which vendors make sense.

Placed workers typically expect weekly pay, while corporate clients usually settle invoices on 30, 60, or 90 day terms. The agency funds the gap, which means wages plus employer taxes plus insurance for several weeks before any client money arrives.

The paradox is that landing a large contract makes the problem worse rather than better: fifty placed workers means four to eight weeks of upfront payroll against a single future invoice.

Factoring is worth understanding because it is assessed differently from a bank facility. A factor underwrites your clients' creditworthiness rather than your agency's operating history, which is why a young agency placing workers at large stable employers can often access it when a bank line would be declined.

Funding also bears on platform selection, because some staffing-native vendors bundle it with their software, which turns two decisions into one relationship. Whether that is an advantage or a dependency depends on how comfortable you are relying on one vendor for both.

Multi-state exposure grows with your client list

Ordinary small employers add states when they hire remotely. Staffing agencies add them whenever a client is in a new state, which makes the footprint expand faster and less predictably.

Registration deadlines are short and set state by state: California, for example, requires employers to register with its Employment Development Department within 15 days of paying more than $100 in wages. Late registration typically produces back taxes and penalties running from the worker's start date rather than from the date you noticed.

New hire reports follow the worker too: federal law gives an employer no more than 20 days from the date of hire to report a new employee to the state, and several states set shorter deadlines. Between registration and reporting, an agency's new client in an unfamiliar state is a compliance event with a lead time, not just a sales win.

When comparing platforms, ask specifically how additional states are priced and whether the vendor assists with registration or simply files once you have account numbers. The distinction is worth real money for an agency adding several states a year.

The onboarding gap payroll platforms leave open

Every payroll platform above handles paying a worker once they exist in the system. Getting them into the system, compliantly and fast enough that the placement is not delayed, is a separate problem and the one most directly tied to revenue.

The arithmetic is simple. A placed worker who has not completed paperwork cannot start, and a worker who has not started cannot be billed. Every day of delay per placement, multiplied by placement volume, quickly outgrows the cost of the software that removes it. Agencies shorten the wait by moving the forms into a workflow the worker can finish and sign from a phone.

Rows one, four, five, and six are where the delay lives, and most of that work sits outside what a payroll platform does.

The I-9 in particular requires examining original documents within three business days of the start date, in the worker's physical presence unless the agency uses E-Verify and the remote alternative, which replaces the in-person check with a live video call. For a worker placed at a distant client site, that requirement is a logistics problem rather than a form problem.

Where FirstHR fits

FirstHR is our product: an onboarding and HR platform, not a payroll provider. Paying placed workers, billing clients, and pay and bill come from the platforms in the tables above, so if that is the problem, one of them is the answer.

What we handle is the layer in the table above that payroll platforms leave open: onboarding workflows with tasks assigned and tracked, e-signature on assignment terms and onboarding documents with an audit trail of who signed what and when, document management with expiry dates, training delivery with completion tracking for client-site requirements, and employee records covering the whole placed population.

Pricing is flat by plan rather than per employee: $98 a month for up to 10 people, $198 for 11 to 50, and a custom Enterprise plan above that, where an agency with more than 50 people in the system will land. For a business whose worker population churns continuously, that behaves differently from per-employee pricing.

It sits alongside whichever payroll platform you use rather than replacing it. It is the wrong choice for an agency whose problem is pay and bill configurability, and the right one for an agency whose placements are delayed by paperwork rather than by payroll.

Which platform fits your agency

The right platform is the one built for your agency's biggest constraint. Find your situation in the left column and start with the option beside it.

Two of those rows route away from staffing-native platforms deliberately. An agency placing under fifty workers with simple bill rates does not need a full back-office implementation, and an agency whose bottleneck is onboarding will not fix it by buying a better back office.

Whichever row describes you, make the two payroll decisions separately: pick internal payroll from the published rates above, and ask each staffing-native vendor for a written quote and a dated implementation plan, since none publishes either.

Frequently Asked Questions

What payroll software do staffing agencies use?

Most run two systems. Placed workers need a staffing-native platform with pay and bill, such as TempWorks, Avionte, or Bullhorn, sometimes with Greenshades running the payroll. Internal recruiters and account managers can sit on general SMB payroll such as Gusto, OnPay, or Patriot at published rates. Agencies running placed workers through general payroll usually discover the gap at the first invoicing cycle.

What is pay and bill in staffing?

Pay and bill is the linkage between what you pay a placed worker and what you invoice the client, driven from one approved time record. The system pays at the pay rate, invoices at the bill rate, and reports the margin between them. General payroll handles only the first half, because ordinary employers have no client to invoice.

Can a staffing agency use Gusto or OnPay for placed workers?

For a small agency with a handful of long-term placements, sometimes. Both pay W-2 and 1099 workers and file in multiple states (Gusto from its Plus tier). OnPay also includes state new hire reporting and bills only for people included in that month's pay runs. Neither does client invoicing, bill rates, or margin reporting, so you track those separately. That breaks well before a hundred placements.

How long does staffing payroll software take to implement?

Staffing-native platforms are migrations rather than signups, and none of them publishes a timeline, so get a dated project plan from the vendor before signing. General SMB payroll for internal staff usually starts with a self-serve signup. Avoid scheduling a cutover near year-end while W-2 processing is in flight.

How do staffing agencies fund weekly payroll?

Workers expect weekly pay while clients settle on 30 to 90 day terms, so the agency funds several weeks of wages and taxes in advance. Common solutions are payroll funding offered alongside staffing software and invoice factoring, where a factor advances most of the invoice value up front and releases the rest, minus its fee, when the client pays.

What is the difference between recruitment and staffing agency payroll?

The terms mean the same thing, but recruitment is British usage and staffing is American. That is why tools sold as recruitment payroll software tend to be UK products built around HMRC recognition and auto-enrollment, which a US agency cannot use. The underlying need is identical: pay placed workers, invoice clients for their hours, and stay compliant across jurisdictions.

Do placed workers get W-2 or 1099?

It depends on the arrangement, not on the fact of placement. A temp working under your direction and schedule at a client site is usually a W-2 employee of the agency. A genuinely independent contractor on a defined project may properly be 1099. Most platforms support both, but the classification decision and the misclassification liability sit with the agency.

What does staffing payroll software cost?

Staffing-native platforms are quote-only: TempWorks, Avionte, Bullhorn, and Greenshades publish no rates, so the number comes out of a sales process. General SMB payroll for internal staff is mostly published, with full-service entry tiers at $37 to $49 a month plus $5 to $6 per employee.

How fast should placed worker onboarding be?

Fast enough that paperwork never holds up the first billable hour, because a worker who has not completed it cannot start and cannot be billed. Phone-friendly forms that workers complete and sign on the spot remove most of the waiting that email attachments create.

What paperwork does a placed worker need before starting?

Form I-9, with document examination within three business days of the start date (in person unless the agency qualifies for the remote examination alternative); a signed W-4 and state certificate; direct deposit authorization; and acknowledgment of client-site policies or safety training. At volume, the constraint is rarely the forms; it is completing and countersigning them before day one.

Do staffing agencies need multi-state payroll?

More often than most small employers, because placements follow client locations. A worker in a new state triggers withholding and unemployment registration obligations there, plus workers compensation coverage where the state requires it, and puts you under that state's employment laws. Each state sets its own short registration window, so a new client in a new state carries a lead time.

Should a staffing agency outsource payroll entirely?

It is a real and common option, distinct from buying software. Providers offer an outsourced back office covering payroll processing, tax administration, invoicing, and often funding as a package. Agencies growing faster than their admin capacity benefit most, since the funding solves cash flow at the same time. The tradeoff is cost per transaction and less direct control of client billing.
