Every staffing agency runs the same math problem on a loop: workers get paid weekly, clients pay whenever their AP department gets around to it, and somewhere in that gap sits a business trying to survive on timing it doesn’t control. This isn’t a sign of bad management. It’s just what the staffing model looks like from the inside. 

The U.S. staffing industry was projected to generate approximately $188 billion in revenue in 2025, and a meaningful share of that revenue spends weeks sitting in accounts receivable before it ever becomes usable cash. Clients commonly run net 30, net 45, or net 60 terms, sometimes net 90 for larger corporate accounts, while the agency’s own payroll obligation doesn’t wait on any of that. Average days’ sales outstanding in the industry often exceeds 45 days. On net-45 terms alone, an agency typically carries six to seven payroll cycles in outstanding receivables before the first invoice clears, compared to four to five cycles on net-30 and eight to nine weeks of continuous payroll funding on net-60.  

So how does an agency actually keep payroll funded while that gap sits open? A few different ways, usually layered together rather than relied on alone. 

Selling invoices for immediate cash 

Invoice factoring is the most common answer in this industry, and for good reason: staffing is one of the most factoring-intensive sectors in the country. An agency sells its unpaid client invoices to a factoring company and receives an advance, typically 85 to 92 percent of the invoice value, within 24 to 48 hours, at an all-in annual cost of 18 to 36 percent. The factor collects from the client directly when the invoice comes due and remits the remainder, minus its fee. That cost sounds steep until it’s compared against missing payroll or turning down a contract because the cash isn’t there yet.  

Lining up a payroll funding facility 

Once an agency has enough history and a creditworthy client base, a dedicated payroll funding line tends to cost meaningfully less than factoring. Qualifying for a payroll funding line can reduce financing costs by 40 to 60 per cent compared to factoring. The mechanics are similar in spirit, borrowing against receivables, but the agency keeps more of its margin since it isn’t selling the invoice outright. This usually becomes the better option as an agency scales past its early, thinly capitalized stage.  

Holding a cash buffer sized to the actual gap, not a guess 

A useful exercise here is calculating the real size of the gap rather than estimating it. Weekly gross payroll typically carries 15 to 25 per cent in employer burden on top of base wages, covering things like FICA, FUTA, SUTA, workers’ comp, and benefits, and that full number is what actually needs to be funded across however many payroll cycles run before the average client pays. Knowing that figure precisely, instead of operating on a vague sense of “we’re usually fine,” is what separates agencies that plan for the gap from ones that get surprised by it.  

For a sense of scale: a staffing agency billing $500,000 a month with a 45-day average collection cycle has roughly $750,000 permanently locked in accounts receivable, cash the agency has earned but can’t yet spend. Gross margins also vary by placement type, running 20 to 25 per cent for temporary staffing, 25 to 35 per cent for temp-to-hire conversions, and 20 to 30 per cent of first-year salary for direct-hire placements, which makes service mix a real factor in how tight that gap actually feels.  

Structuring client terms instead of accepting them by default 

Not every client needs net-60. Some agencies negotiate shorter terms upfront for new accounts, request a deposit or partial prepayment on large placements, or simply decline terms that don’t work for their cash position, rather than accepting whatever the client’s standard contract says. None of this requires being difficult with clients; it just means treating payment terms as a negotiated point instead of a given. 

Shrinking the actual collection time, not just the stated terms 

There’s a real difference between a client’s net-30 terms and how long that invoice actually takes to collect. Slow invoice delivery, no follow-up on anything overdue, and limited payment options all stretch real DSO past whatever the contract says. Tightening that gap, sending invoices the moment work is verified, following up automatically before something goes overdue, giving clients an easy way to pay immediately, recovers cash without financing anything or renegotiating a single contract. 

Frequently asked questions 

How do staffing agencies pay workers before clients pay their invoices? 

Most rely on some combination of invoice factoring, a payroll funding line, and a cash reserve sized to their specific payment gap. Factoring is the most common entry point since approval depends on the client’s creditworthiness rather than the agency’s, and many agencies transition to cheaper payroll funding facilities as they build a track record. 

Why do staffing agencies have cash flow problems even when they’re profitable? 

Because payroll and collections move on completely different schedules. Workers are typically paid weekly while clients pay on net 30, 45, or 60-day terms, sometimes longer. A profitable agency can still run out of cash simply because the money it’s owed hasn’t arrived yet. 

What is a normal collection period for staffing agency invoices? 

Average days sales outstanding in the staffing industry often exceeds 45 days, even when contracted terms say net 30, since actual collection time depends on invoicing speed and follow-up, not just the stated terms. 

Is invoice factoring expensive for staffing agencies? 

It costs more than a payroll funding line, typically working out to an annualized rate of 18% to 36% depending on how quickly the client pays, but it provides cash in a day or two and is usually compared against the much higher cost of a missed payroll run. 

Let Forwardly close the gap between payroll and payment 

The factoring and funding options above all treat the gap as something to finance. There’s a simpler lever sitting underneath most of it: collect faster, and there’s less gap to finance in the first place. 

Forwardly handles that by getting invoices to clients the moment work is verified, with payment links built right in, so a client can pay by instant transfer, ACH, or card the second they open the bill instead of routing it through their own AP queue first. Repeat clients get set up on recurring invoicing and automatic payments, which means nobody on your team is manually re-sending the same invoice every cycle, and anything that does go overdue gets an automated follow-up without anyone having to remember to chase it. 

Agencies using this report collect up to 5x quicker, which sounds dramatic until you consider what it’s being measured against: net-45 and net-60 terms that used to be the default. Faster collection means payroll comes from cash that’s actually in the bank, not a factoring advance or a funding line carrying its own cost. And since every payment syncs to your accounting or ERP system on its own, the 70-plus hours a month that a lot of finance teams spend reconciling collections mostly go away, too.
