Payroll Guide
By Anthony Moretti · Updated June 2026
Staffing agency payroll is volume payroll under deadline. Weekly cycles, a mixed W-2 and 1099 workforce, client-billable reporting, high-volume onboarding, and multi-state temps all have to run cleanly every single week. This guide breaks down what agencies need to manage.

Temporary and contract workers expect to be paid weekly, and for many of them a dependable Friday check is the reason they stay on assignment instead of leaving for another agency. That expectation forces staffing firms onto a weekly cadence: 52 payroll cycles a year, each with its own time collection, approval, tax calculation, funding, and direct deposit. There is no quiet week, and a single missed or late run damages the agency’s reputation with both workers and clients.
The cadence is the defining operational challenge. An agency that processes payroll in-house has to repeat the entire cycle every week without error, and the people doing it can never get ahead. This is exactly the kind of repetitive, deadline-driven work that a managed payroll process is built to absorb, turning a weekly scramble into a reliable routine that simply happens.
Many staffing agencies place both W-2 temporary employees and 1099 independent contractors, and the two are handled in completely different ways. W-2 workers have income and payroll taxes withheld and matched, receive a W-2 at year end, and count for unemployment and workers compensation. 1099 contractors are paid gross with no withholding and receive a 1099-NEC when they are paid $600 or more in a year. Running both populations means maintaining two parallel sets of tax and reporting logic in the same payroll.
The central risk is classification. If a worker who is functionally an employee is paid as a 1099 contractor, the agency is exposed to back taxes, the employer share of FICA, penalties, and interest, and the determination is made by the facts of the working relationship, not by what the contract says. For a staffing agency, where the placement business depends on getting worker status right at scale, a clean and defensible classification for each role is not optional. The payroll process has to keep the two populations correct and produce accurate W-2s and 1099s at year end.
A staffing agency makes its money on the spread between what it pays a worker and what it bills the client. That makes payroll and billing two views of the same timesheet. Client-billable reporting connects each worker’s approved hours to a pay rate and a bill rate tied to the right client, so the agency can invoice accurately and see its margin on every placement.
When payroll and billing run off different numbers, the agency either overpays workers, underbills clients, or both, and margin quietly leaks. The fix is a single source of approved hours feeding both the paycheck and the invoice. A managed payroll process that captures hours by worker and by client keeps paychecks and invoices reconciled and keeps placement-level margin visible, which is the number an agency owner actually runs the business on. BEG managed payroll is built to handle that hours-to-pay-to-bill flow.
Staffing is a high-churn model by design. Workers start and end assignments constantly, so the agency is perpetually onboarding new hires, collecting tax forms and direct-deposit details, and processing departures. At volume, onboarding is itself a major workload, and any backlog there means new workers cannot be paid on time, which feeds turnover.
Placing workers across state lines adds tax complexity on top of the volume. Each state where work is performed can require its own income-tax withholding and its own unemployment registration, so an agency operating regionally accumulates multi-state obligations quickly. A managed payroll process handles the high-volume onboarding intake and allocates each worker’s wages and taxes to the correct state automatically, so the agency can scale placements without scaling its administrative headcount in step.
Staffing agency payroll is the intersection of high frequency, high volume, mixed worker types, billing dependency, and multi-state tax. Doing it in-house ties up staff in a weekly cycle that can never slip and exposes the agency to classification and multi-state errors. A fully managed service runs the weekly cadence reliably, keeps W-2 and 1099 populations correct, ties hours to billing, and handles onboarding and multi-state tax, all for a flat $25 to $45 per employee per month.

FAQ
Temporary and contract workers expect to be paid weekly, and a reliable weekly check is often the difference between keeping a placement filled and losing the worker to a competitor. Weekly payroll means 52 cycles a year instead of 26, each with its own time collection, tax calculation, and funding. The frequency multiplies the operational load, which is why agencies need a payroll process built to run cleanly every week without fail.
Staffing agencies often place both W-2 temporary employees and 1099 independent contractors, and the two are taxed and reported completely differently. W-2 workers have taxes withheld and matched and receive a W-2; 1099 contractors are paid gross and receive a 1099-NEC if they earn $600 or more. The biggest risk is misclassifying a worker who is really an employee as a 1099 contractor, which creates back-tax and penalty exposure. The classification has to be defensible for each role.
Because a staffing agency bills its clients based on the hours its placed workers actually work, payroll and billing are two sides of the same timesheet. Client-billable reporting ties each worker's hours, pay rate, and bill rate to the right client so the agency can invoice accurately and see margin per placement. When payroll and billing draw from one clean set of approved hours, invoices and paychecks stay in sync and margin stays visible.
When an agency places workers across state lines, each state can require its own income tax withholding and its own unemployment-tax registration, and the rules follow where the work is performed. A high-volume agency placing temps in several states quickly accumulates multi-state filing obligations. BEG runs staffing payroll through one managed process at $25 to $45 per employee per month so each worker's wages and taxes are allocated to the correct state automatically.
