What is the difference between factoring and payroll funding? 

Where invoice factoring ends and full payroll funding begins, and which one a growing staffing agency should choose.

The short answer

Factoring advances cash against invoices you have already raised. Payroll funding goes further: the provider funds and often processes the payroll itself, handles employer taxes and back office, then collects from your client. Factoring is cheaper and keeps control in-house; payroll funding costs more and removes the operational burden.

The distinction is scope, not just price. A factor buys receivables. A payroll funder underwrites the whole temp cycle — timesheet to payment — and in the full-service form runs payroll processing, employer tax filings, workers' compensation administration and collections alongside the advance.

That matters most in the first two years. A founder placing forty contractors with no back office is buying capacity, not just cash, and paying two or three points more for it can be rational. Once you have a controller and a working ATS-to-payroll pipeline, the same spend is waste and a straight factoring line is cheaper.

Model both as an effective annual rate on the cash you actually use, then add the cost of the staff you would otherwise hire. That comparison — not the headline percentage — is the one that decides it.

How this differs by US state and metro

The answer above holds nationally. What changes locally is registration, insurance, wage rules and how much cash each contractor consumes — these are the states and metros founders ask us about most.

Local questions

Does this change if I start in Illinois?

The national answer holds. What changes in Illinois is local: Illinois compliance costs are front-loaded, and light industrial margins are thin, so the funding line has to cover both the payroll gap and the administrative load. Model the long-assignment pay step-up into your bill rate from day one or it will eat the margin later. Check the Illinois page before you register anything, and model the cash gap on Illinois pay rates rather than national averages.

Is the answer different in Ohio than in Illinois?

The economics are the same shape; the local detail is not. In Ohio: Ohio's industrial base runs high headcount at moderate bill rates. That combination means the cash gap grows fast while margin per contractor stays modest, so a factoring line sized to invoice volume usually beats trying to self-fund. That affects your registration checklist and your working capital number, not the underlying principle.

Which US cities does this apply to?

All of them — but we publish metro-level bill rate, wage and startup cost detail for Pittsburgh, Chicago, Columbus, Cleveland and more, because pay rates and buyer mix vary far more between metros than between states.

Do I need a separate licence in every state I place in?

You register where you have employees and where you do business, not once nationally. Most states require unemployment insurance and withholding registration plus workers' compensation cover; a minority licence employment agencies, and some cities — New York City among them — licence separately from the state. Confirm each state and city before your first placement there.
