Accounts Receivable Financing: How It Works

What accounts receivable financing is

Accounts receivable (AR) financing is a way for a business to unlock cash tied up in unpaid customer invoices. In many structures, a lender advances funds against eligible receivables and takes a security interest in those invoices (and often related deposit accounts). You typically keep ownership of the receivables and remain responsible for collection, unlike classic invoice factoring, where a factor often buys the invoices.

Providers use labels loosely: “AR financing,” “receivables financing,” “invoice financing,” and “asset-based lending (ABL) against AR” can mean different legal forms. Always read whether you are borrowing against receivables, selling them, or signing another commercial agreement.

How AR financing typically works

A common pattern (contract-specific):

1. Eligibility review: the provider reviews invoice aging, customer concentration, dispute history, and your financials.
2. Borrowing base: eligible AR is multiplied by an advance rate to set how much you can draw.
3. Advance / draw: you borrow against the borrowing base, often through a revolving facility.
4. Collections: customers may pay you or a controlled account; remittances reduce the outstanding balance.
5. Ongoing reporting: aging schedules, borrowing-base certificates, and audits are common.

Illustrative arithmetic only (not a quote): if eligible AR is $200,000 and the written advance rate is 80%, the borrowing base would be $160,000 before reserves, ineligibles, and existing draws. Your actual advance rate, reserves, and fees are whatever the contract states.

AR financing vs invoice factoring

These are patterns, not guarantees. Some “invoice financing” products behave like loans; some factoring contracts include recourse that feels loan-like. Compare the written structure, not the marketing name. For a factoring-first explainer, see invoice factoring.

How AR financing compares to other business funding

• Revenue-based financing (RBF): repayments often track revenue or card sales, not a borrowing base of invoices. Useful when cash flow is strong but AR is thin.
• Equipment financing: funds a hard asset purchase or lease; collateral is equipment, not customer invoices.
• Bank line of credit: may be unsecured or broadly secured; AR facilities are usually tightly tied to eligible receivables and reporting covenants.
• Merchant cash advance: typically a purchase of future receivables / sales with frequent remittances; different economics and enforcement tools than a monitored AR line. If you are weighing that option, our guide to how a merchant cash advance works explains the usual structure.

Match the product to the asset you actually have: invoices, equipment, or future sales.

Costs and terms to get in writing

Do not rely on blog percentages or “from” rates. Ask for a written summary that includes:

• Advance rate and how eligible AR is defined (aging caps, foreign customers, affiliates, disputed invoices).
• Interest or discount method, and whether fees are deducted from advances.
• Unused line / facility fees, audit fees, wire fees, and early-termination fees (if any).
• Concentration limits (max % per customer).
• Lockbox / blocked-account requirements and who controls remittances.
• Default triggers, cross-defaults, and personal or corporate guarantees.
• UCC filing scope and what collateral is covered beyond AR.

If numbers appear in marketing, treat them as illustrations until you see them on your term sheet.

Who AR financing tends to fit

Often a better conversation when:

• You sell B2B on net-30 / net-60 terms and invoices are largely undisputed.
• Customer credit quality is strong enough for the lender’s eligibility rules.
• You need a revolving working-capital tool rather than a one-time factoring of a few invoices.
• You can support monthly aging and borrowing-base reporting.

It may be a poor fit when invoices are heavily disputed, consumer receivables dominate, concentration is extreme, or you need cash against purchase orders that are not yet invoiced (see purchase order financing if that page is live).

Diligence checklist before you sign

1. Confirm legal form: loan, purchase, or hybrid, and which state’s law governs.
2. Map the full cash cycle: who invoices, who collects, where money lands, how quickly reserves release.
3. Stress-test concentration and aging rules against your real customer mix.
4. Price the all-in cost at your expected utilization (not only the headline rate).
5. Have counsel review guarantees, confession-of-judgment or cognovit language (if present), and default remedies.
6. Align internal ops: can your team produce clean aging reports on the lender’s schedule?
