Staffing Agency Payroll Funding: Sizing the 60-Day Gap

Covering Payroll While Clients Pay in 60 Days: Funding for Staffing Agencies

A staffing agency that pays workers every week and gets paid in 60 days carries about eight and a half weeks of payroll before the first client payment arrives. Invoice factoring covers that gap by advancing most of each invoice when you bill, so payroll is funded by work already done rather than by the agency's own credit.

Before asking how much funding you can get, work out how much payroll you carry: weekly payroll times your clients' real payment days, divided by seven. That one number tells you whether you need a facility at all, how big it has to be, and how much a new contract will cost you in cash before it pays.

How much payroll a staffing agency really carries

The gap is simple arithmetic: weekly payroll multiplied by the number of weeks between paying the worker and collecting from the client. Take an agency with $40,000 of weekly payroll. On 30-day terms it carries a little over four weeks of payroll at any time; on 60-day terms, more than eight; on 90-day terms, almost thirteen. Late payers and the days it takes to send an invoice make the real number higher.

Client payment terms	Weeks of payroll carried	Payroll carried at $40,000 a week	Payroll carried at $100,000 a week
30 days	4.3	$171,000	$429,000
45 days	6.4	$257,000	$643,000
60 days	8.6	$343,000	$857,000
90 days	12.9	$514,000	$1,286,000

Derived: weekly payroll × (payment days ÷ 7), rounded. Before invoicing delays and late payments.

Why the gap grows faster than the agency

Every new contract adds its weekly payroll to the pile for the full length of the client's terms. An agency on 60-day terms that wins a client worth $10,000 of weekly payroll needs roughly $86,000 more cash before that client pays once. That is why agencies run short of cash in their best quarters, not their worst. A bank line sized on last year's financial statements cannot keep up with that, because it is set once a year while billings move every week.

Sizing invoice factoring to the payroll gap

Invoice factoring is the sale of your client invoices: the facility advances part of each invoice when you bill and releases the rest, less its fee, when the client pays. Voxen's facilities advance 70% to 95% of the invoice face value, and staffing typically sees 90% to 95%. Because you bill clients more than you pay workers, the advance can cover the whole payroll.

The staffing industry page explains the setup step by step.

Illustration: weekly payroll of $40,000 billed to clients at $52,000. At a 90% advance, the facility pays $46,800 when the invoices go out, which is more than the payroll they represent.
The facility grows with your billings, so a new client adds to it without a new application, within the limit set for that client.

Three numbers to bring to a factoring conversation

An agency that knows these three numbers gets a useful answer in the first call, instead of a general one.

The first two give the size of the gap from the table above. The third tells you how much of it a facility can carry.

Weekly payroll, including the employer's share of source deductions, averaged over the last three months.
The days each major client actually takes to pay, from your invoice aging, not the terms on the contract.
The share of your billing that sits with your largest client.

When factoring is the wrong tool for an agency

Factoring solves one problem, slow-paying business clients, and it is not the answer to every cash question an agency has.

Clients that routinely pay past 90 days. Invoices are typically eligible up to around 90 days; beyond that, the problem is collections, not financing.
One client is most of your billings. Facilities set limits per client, so heavy concentration caps what you can draw.
Costs not tied to an invoice, such as recruiting software, deposits or a new office. A line of credit fits those better, and many agencies run both.
A bank already offering an operating line at bank pricing on your receivables. That is usually cheaper; compare it on the bank loan vs factoring page.

What Voxen looks at in a staffing file

The decision rests mostly on who owes you money. Voxen asks for your client list and invoice aging, looks at how long each client actually takes to pay and how much of your billing sits with the largest one, and checks your bank statements and any existing financing or registered security on your receivables. Your agency's age and your personal credit matter less than in a bank file. Voxen does not promise a facility size before seeing the client list; it is set by your clients, not by a formula.

What to do next

Pull your client list and invoice aging, and calculate the payroll you carry with the formula above. Then apply with Voxen, or read the staffing industry guide first if you are new to factoring.

Frequently asked questions

How do I calculate how much payroll funding my agency needs?

Multiply your weekly payroll by the number of days your clients actually take to pay, divided by seven. An agency with $40,000 of weekly payroll on 60-day terms carries about $343,000 of payroll at any time, before invoicing delays and late payers.

Does a factoring facility grow when the agency wins a new client?

Yes. A factoring facility is sized on your billings, so new invoices add to it, within the limit set for each client. The new client's own payment record decides how much of its invoices can be advanced.

What if one client is most of my billing?

Facilities set limits per client, so heavy concentration on one client caps how much you can draw against it. Spreading billings across more clients raises what the facility can carry.

Can an agency use factoring and a line of credit together?

Yes, and many do. Factoring carries the payroll tied to invoices; a line of credit covers costs that are not tied to an invoice, such as software, deposits or office expenses.

Is invoice factoring a loan?

No. Factoring is the sale of your receivables: the facility buys the invoice and is paid by your client. It does not add debt to your balance sheet the way a bank loan does.
