How Consulting Firms Turn Net-60 Invoices Into Cash Today

Engineering, architecture, and consulting firms front payroll for months before enterprise clients pay. Accounts receivable factoring closes that gap in days.

The Payroll-Before-Payment Problem

A professional services firm sells hours, and hours are paid for on the fifteenth and the thirtieth whether or not the client has paid. When your clients are Fortune 1000 enterprises, hospital systems, or municipalities, Net-60 is the starting point and Net-90 is common once invoices route through a procurement portal. Every dollar of growth requires you to fund another two to three months of payroll in advance.

This is why profitable firms run out of cash. A twenty-person engineering group with $4 million in annual billings and a 65-day average collection cycle has roughly $700,000 permanently locked in receivables. Win a large new contract and that number jumps before a single payment arrives, which is the moment most firms either slow their hiring or reach for expensive short-term money.

The trap is that the receivable is not risky, it is just slow. Your client is creditworthy, the work is accepted, and the invoice will be paid. That combination of low credit risk and long duration is precisely what accounts receivable factoring exists to solve.

How Factoring Works for a Services Firm

In a factoring facility, you sell approved invoices to the funder and receive an advance, typically 80% to 90% of face value, within 24 to 48 hours of submission. When your client pays on their normal schedule, you receive the reserve balance less the factoring fee. Fees generally run 1% to 3% of invoice value for a 30- to 60-day cycle, depending on client credit quality, invoice size, and monthly volume.

The critical distinction from a bank line is what gets underwritten. Factoring underwrites your client’s credit, not primarily your balance sheet. A four-year-old consultancy with thin equity and lumpy earnings can often access a facility that a bank would decline, because the funder is looking at the payment history of the enterprise on the other end of the invoice.

Angel Funding Group structures these as either notification or non-notification facilities. Non-notification keeps the arrangement invisible to your client, which matters a great deal to firms whose relationships depend on projecting institutional stability. Ask about it early, because not every funder offers it and it can be the deciding factor in whether factoring is workable at all.

Progress Billing, Milestones, and What Is Actually Fundable

Not every invoice is factorable. The general rule is that the work must be completed and accepted, with no remaining contingency to performance. For architecture and engineering firms working on progress-billing schedules, that means a milestone invoice is fundable once the client has signed off on the deliverable, but a pre-billed retainer or an unbilled work-in-progress balance generally is not.

Retainage is a separate conversation. Design contracts that hold back 5% to 10% until project completion create a receivable with an uncertain timeline, and most funders will exclude it from the borrowing base or advance against it at a steeply reduced rate. Know which portion of your aging is truly eligible before you size the facility, or you will be disappointed by the availability calculation.

Concentration limits also apply. If one client represents 50% of your receivables, expect the funder to cap advances on that account, often at 30% to 40% of the total facility. That constraint is annoying in the short run and healthy in the long run, because it forces the same client diversification that protects the firm anyway.

When a Line of Credit Is the Better Answer

Factoring is not always the right tool. If your firm has three-plus years of clean financials, a debt service coverage ratio above 1.25x, and a receivables aging where the vast majority sits under 60 days, a conventional business line of credit will almost always be cheaper. Lines priced at prime plus a spread cost far less annually than a 2% per-invoice factoring fee applied twelve times a year.

The honest way to compare is to annualize. A 2% fee on a 45-day cycle is roughly 16% annualized, which is expensive relative to a line but cheap relative to turning down work or missing payroll. Many firms use factoring as a bridge for two to three years while building the financial history a bank line requires, then graduate. That is a completely legitimate path.

Angel Funding Group frequently structures both: a modest committed line for routine timing gaps, plus a factoring facility that flexes when a large contract lands and receivables spike. Having the second facility already documented and dormant means you can accept a transformative engagement without a financing scramble. That optionality is often worth more than the rate difference.
