Quick answer
Payroll funding advances up to 95% of a staffing agency's approved weekly invoices, usually within 24 hours, so temporary workers are paid on Friday while clients pay on 30-, 60- or 90-day terms. Because the advance is sized by client credit rather than by the agency's balance sheet, capacity grows with each placement instead of capping it.
Key takeaways
- Payroll runs weekly, client terms run 30–90 days: the facility exists to bridge that gap, not to repair a thin bill-to-pay spread.
- Funding follows the approved timesheet — unapproved hours generally do not support an eligible receivable.
- Advances reach 95% at 0.75%–3% per 30 days, so days sales outstanding, not the headline rate, decides what you actually pay.
- Bundled payroll processing and tax filing can be excellent value, but employer-of-record liability stays with you.
- Credit-check the client before the placement is made, not after the first invoice ages past terms.
Why does growth make a staffing agency's cash position worse?
Staffing is one of the few industries where winning is financially indistinguishable from losing until the cash arrives. Every new assignment creates a payroll obligation that lands within days and a receivable that lands weeks later. The faster you place, the wider the gap grows, and the gap is funded entirely out of the agency's own cash until something closes it.
The arithmetic is unforgiving. Take an agency billing $100,000 a week, with wages and employer burden running at roughly 72% of billings — $72,000 out the door every Friday. On net-45 terms, the first week's invoice is not collected until somewhere around week eight. That is roughly seven payroll cycles, about $504,000, funded before a single dollar of that revenue comes back. Double the headcount and the figure doubles with it.
This is why staffing firms with healthy gross margins and full order books still stall. The constraint is not profitability and it is not demand; it is the number of payrolls the owner can personally bankroll. Payroll funding converts that constraint into a variable cost that scales with billings.
What exactly gets funded — the timesheet or the invoice?
The invoice is what is funded, but the approved timesheet is what makes the invoice fundable. A funder's underwriting question is whether the client has accepted the hours, because an accepted hour is an amount the client owes and an unaccepted hour is a conversation. Agencies that keep the approval record attached to the invoice fund faster and fund more of each batch.
- 1Place against signed paperwork. A countersigned master service agreement with an agreed bill rate, plus a purchase order or requisition number where the client uses them. Verbal rate agreements are the most common cause of a short-paid first invoice.
- 2Capture approved time before the cut-off. The client manager signs off the hours, or the VMS releases them. Chase approvals on Monday, not Thursday — the approval, not the work, is what starts the clock.
- 3Invoice against the approval. The invoice references the approval record, the PO or requisition number and the assignment. Everything on the invoice should be traceable to something the client has already agreed.
- 4Submit the schedule of accounts. The week's invoices go to the funder as a batch with the supporting approvals. Verification confirms the hours were accepted and the amount is due.
- 5Advance lands before payroll clears. Up to 95% of the batch is wired, typically within 24 hours of submission, so the funds are in place before Friday's payroll files.
- 6Client pays; the reserve releases. When the client settles, the reserve is released less the fee that accrued for the days the invoice was open.
What does one funded week look like in cash?
The worked example below takes the same $100,000 billing week and runs it all the way through to the reserve release. It prices the fee at 1.5% for the first 30 days with a further 0.75% for the next 15-day increment — a common structure within the 0.75%–3% per 30 days range — on a client who pays on day 45.
A $100,000 week of approved staffing invoices at a 90% advance, 1.5% per 30 days plus 0.75% per additional 15 days, collected on day 45.
| Approved invoices for the week | $100,000 |
|---|---|
| Advance at 90%, funded within 24 hours | $90,000 |
| Payroll and employer burden due Friday | $72,000 |
| Cash left over after payroll | $18,000 |
| Fee at 2.25% for 45 days | $2,250 |
| Reserve released when the client pays | $7,750 |
You receive $97,750 of the $100,000 billed, at a total cost of $2,250 — and the $72,000 payroll was covered six weeks before the client paid.
How do client payment terms differ by placement channel?
Not all staffing receivables behave the same way, and the channel a placement comes through is usually a better predictor of payment timing than the client's size or credit rating. Vendor management system and managed service provider programs deserve particular attention: they are excellent for volume and they systematically extend the cycle, because hours must clear the VMS before an invoice can even be raised.
| Channel | Typical terms | What tends to slow payment |
|---|---|---|
| Direct commercial client | 30–60 days | A single accounts payable contact, manual timesheet approval, holiday cut-offs |
| IT staffing and enterprise consulting | 45–90 days | Enterprise AP cycles and purchase orders that exhaust their value mid-assignment |
| Medical and nurse staffing | 30–75 days | Credentialing files and shift-record reconciliation before AP will release payment |
| VMS / MSP program | Set by the program, often at the long end | Hours must clear the VMS before invoicing; one disputed line can hold an entire batch |
What does the funding actually have to cover?
Owners often size a facility against gross wages and are caught out by burden. The weekly obligation is considerably larger than the payroll register, and several of its components are statutory — meaning they must be paid on time whatever else is happening.
- Gross wages for every worker on assignment that week
- The employer share of FICA, plus federal and state unemployment tax
- Workers' compensation premium, which for light-industrial and clinical placements can be a material cost per hour
- Benefits, and housing or per-diem stipends on travel assignments
- Recruiter and salesperson commissions, which are usually paid on billings rather than on collections
- Background checks, drug screens, licensing and credentialing for new starts
- General liability, professional liability and employment-practices coverage required by client contracts
Should I use the funder's back office for payroll and tax filing?
Many payroll funding programs bundle back-office services: payroll processing, payroll-tax filing and deposits, invoicing, collections support and credit checks on prospective clients. For an agency under fifty internal placements, this is often genuinely cheaper and more reliable than hiring the equivalent in-house, and it removes the single-point-of-failure risk of one bookkeeper who knows how everything works.
Two cautions. First, price the services separately from the advance so you can tell whether you are buying funding, administration or both — otherwise a bundled quote is impossible to compare with anything. Second, and more importantly, outsourcing the filing does not outsource the liability. Payroll-tax obligations remain with the employer of record, and unpaid payroll tax is the fastest route to a lien that stops a facility outright.
How do I stop a client from becoming a credit problem?
In staffing, the credit decision is made at the moment you agree to place, not at the moment you invoice. By the time an invoice is 60 days late you have already paid the worker six or seven times. The discipline that matters is front-loading the check.
- Run the credit check before the placement, using the funder's credit service — it is normally included
- Agree the bill rate, overtime treatment and approval process in writing before the first shift
- Ask the funder for the proposed credit limit on that client and treat it as your own exposure cap
- Watch for a client whose share of your billings is climbing past the concentration limit on your facility
- Escalate a late invoice at the terms date, not thirty days after it
- Re-check existing clients periodically — the risk is rarely the new client you scrutinized, but the old one nobody looked at again
What stops a staffing invoice from being funded?
Most declines at the invoice level are mechanical rather than credit-driven, and nearly all of them are preventable. The common causes are hours billed before client approval, invoices raised before the work week has closed, rate disputes that produce a credit memo after the fact, placements billed to a related entity, and invoices already pledged to another lender or sitting behind a blanket UCC filing.
At the account level, the two recurring obstacles are existing liens that cannot be subordinated and unresolved payroll-tax balances. Both are solvable, and both take longer to solve than most owners expect — raise them at the first conversation rather than at closing.
