Invoice Factoring for Staffing Agencies: Handling Temp Worker Payroll
The specific mechanics of using factoring to fund temp worker payroll—including weekly payroll timing, payroll tax handling, and integrated payroll funding programs.
Key Takeaways
- ✓Temp worker payroll must be funded weekly or biweekly—factoring provides same-week cash.
- ✓Employer payroll taxes add 15%–25% to gross wages—factor this into your advance needs.
- ✓Workers' compensation insurance must be in place before factoring companies advance on staffing invoices.
- ✓Payroll funding programs integrate payroll processing with factoring advances.
- ✓Always maintain a small operating reserve to cover the gap between factoring and payroll ACH settlement.
The Full Payroll Obligation: More Than You Think
When calculating how much factoring you need to cover payroll, many staffing agency owners only think about gross wages. The full employer payroll obligation is higher:
Gross wages: What the employee earns before taxes
Employer FICA: 7.65% of gross wages (Social Security + Medicare)
FUTA (Federal Unemployment): 6% on first $7,000/year per employee (reduced by SUTA credit)
SUTA (State Unemployment): Varies by state, typically 1%–5% of taxable wages
Workers' compensation insurance: 1%–10%+ of payroll depending on job classification
For a $100,000 weekly payroll of temp workers, your total employer cost including taxes and WC might be $115,000–$130,000. Your factoring advance must cover this full obligation.
Integrated Payroll Funding Programs
Some specialized staffing factoring companies offer integrated payroll funding—they don't just advance against your invoices, they calculate, fund, and process payroll on your behalf:
1. You submit approved timesheets to the factor/payroll provider
2. They calculate gross pay, deductions, employer taxes, and net pay for each worker
3. They fund and process payroll (direct deposit or checks) directly
4. The payroll advance is secured against your outstanding client invoices
5. When clients pay, the factor recoups the payroll advance plus fees
This eliminates the need to manage cash flow between the factoring advance and payroll processing—the factor handles the entire cycle.
