Time tracking and payroll compliance for staffing agencies: what to buy and what to build

A generic time clock assumes a simple world: employees work at your location, a manager approves their hours, and payroll runs from those hours. Staffing breaks all three assumptions. Your workers are at client sites, the client approves the hours, and every hour has two prices: what you pay the worker and what you bill the client.

That is why staffing agency time tracking software is its own category, and why many agencies end up with a patchwork of a time clock app, spreadsheets and their payroll provider. This post covers the problems specific to staffing, what to look for in a product, and when building part of the system yourself makes sense.

We build a workforce platform for a staffing company, covering hiring, scheduling, timeclocks and weekly payroll. The lessons below come from that work. This is not legal advice: wage and hour rules vary by state and change, so confirm your staffing agency's payroll compliance obligations with an employment attorney or payroll professional.

What makes staffing time tracking different

Five things set staffing apart from a business where everyone works at one location.

Workers clock in at someone else's site

For example, your worker might be at a warehouse on Monday and an event venue on Thursday. Each site has its own shift times, break rules and supervisor. So the system has to know which assignment each punch belongs to, not just who punched.

Common approaches are a shared kiosk tablet at the client site, or a phone app with the worker's own sign-in. Many agencies need both, because some sites don't allow personal phones on the floor.

The client approves the hours

At most agencies, a client supervisor confirms hours before they are paid or billed. Without software, that means emailed spreadsheets, signed paper timesheets, or phone calls on Monday morning.

Good software gives the client a simple approval screen. It shows only their workers, flags missing punches, and records who approved what and when. That record matters if a client later disputes an invoice.

Overtime and break rules depend on the state, and sometimes the city

Under the federal Fair Labor Standards Act, non-exempt employees must generally be paid at least one and a half times their regular rate for hours over 40 in a workweek. The U.S. Department of Labor's overtime page explains the basics.

Some states go further. California, for example, also requires overtime for hours over eight in a workday, as its Labor Commissioner's overtime FAQ describes. Meal and rest break rules also vary widely by state.

For a staffing agency, the hard part is that one worker can work for two clients in the same week. The hours still add up for overtime purposes. Software that calculates overtime per client, rather than per worker, gets this wrong.

Every hour has a pay rate and a bill rate

You pay the worker one rate and bill the client another, and both can change by shift, by client and by role. Overtime raises both. Holiday or weekend premiums may apply on one side and not the other, depending on the client contract.

So margin reporting depends on getting both sides right for every hour. If pay and billing live in separate systems, they will drift.

Payroll that is final has to stay final

Once a payroll run is approved and paid, its numbers should never change, even if someone later edits a rate or fixes a punch. Instead, corrections belong in the next run as adjustments.

In the platform we build, each finalized payroll is kept as a snapshot. Later edits can't rewrite it. That makes it possible to answer "what did we pay, and why?" months later.

What to look for in staffing agency time tracking software

Whether you buy or build, check for these:

1. Assignments, not just employees. Every punch tied to a client, site and role.
2. Kiosk and phone clock-in, with location or site checks where you need them.
3. Client approval with an audit trail.
4. Overtime calculated per worker across all clients, with rules you can set by state.
5. Separate pay and bill rates with premiums for each.
6. Locked payroll runs, with corrections as adjustments.
7. Exports your payroll provider and accounting software accept, such as QuickBooks.
8. Onboarding in the same system: I-9s, tax forms and background checks, so a worker can't be scheduled before they are cleared.

Buy, build or both?

Several products are built for staffing agencies, and for many agencies one of them is the right answer. Start there. Ask each vendor to walk through a worker who works for two clients in one week and gets overtime, because that scenario reveals a lot.

Building makes sense when your agency has a way of working that the products fight. That might be an unusual approval flow, a mix of industries with very different rules, or a client portal that is part of how you win business.

A common middle path is to keep a payroll provider for tax filing and payments, and build only the parts around it: assignments, timeclocks, client approval and a clean export into payroll. Our build or buy checklist can help you score your own case.

Moving off paper timesheets

If you run on paper or spreadsheets today, a few steps make the move safer:

1. Run the new system alongside the old one for two or three pay periods, and compare the totals.
2. Start with one friendly client before rolling out to all of them.
3. Train site supervisors in person; their approvals drive everything else.
4. Keep the old records exported and archived.

The integrations page covers how we connect timekeeping to QuickBooks and payroll tools so nobody retypes hours.
