Accounts receivable (AR) financing is the bank-lending cousin of invoice factoring. Instead of selling the invoices, the business borrows against the receivables ledger and retains collection. The product sits between factoring (cheaper, more disruptive) and MCA (more expensive, less disruptive) in cost and friction.
The three-way contrast.
| Dimension | AR Financing | Invoice Factoring | MCA |
|---|---|---|---|
| Cost | 6–18% APR | 12–48% APR | 50–65% APR-equivalent |
| Collection | You collect | Factor collects | N/A |
| Customer notice | Usually no | Yes (notice of assignment) | No |
| Advance rate | 70–90% of eligible AR | 70–90% of invoice | Lump sum vs. future revenue |
| Time to set up | 4–8 weeks | 1–2 weeks | 4 hours–3 days |
| Ongoing reporting | Monthly borrowing-base certificate | Per-invoice | None |
| Personal guarantee | Usually yes | Sometimes | Yes |
| Concentration limits | Yes, 15–25% per customer | Yes, 25–40% per customer | None |
Cost comparison: $200K, 1-year average outstanding.
- AR financing, 12% APR on average $200K balance: $24,000 interest.
- Factoring at 2.5% per 30 days, $200K avg outstanding: ~$60,000.
- MCA 1.30 factor on $200K, repaid 9 months: $60,000 cost.
For sustained outstanding balances, AR financing is dramatically cheaper than both factoring and MCA. The savings vs. MCA on $200K outstanding for a year exceed $35,000.
Mechanics.
(1) The business has $400K in eligible accounts receivable on its ledger. (2) Lender (bank or specialty AR lender) advances 80% = $320K against the receivables, structured as a revolving line of credit. (3) Borrower draws as needed, up to the borrowing-base limit. (4) Borrower collects from customers directly; deposits flow into a lockbox or operating account. (5) Monthly borrowing-base certificate updates eligible AR; line size adjusts. (6) Interest accrues only on the drawn balance.
Eligibility for the receivables.
AR financing lenders apply eligibility tests to the receivables before counting them in the borrowing base: - Aged under 90 days from invoice date (eligibility usually drops to zero past 90). - Customer not in bankruptcy or known financial distress. - Customer not the borrower's affiliate or related party. - Customer concentration under 15–25% (excess concentration excluded). - Invoice not subject to dispute, chargeback, or offset. - Customer in approved-country list (foreign AR often excluded).
Typical eligibility rate: 70–85% of gross AR.
The borrowing-base certificate.
Every month (or sometimes weekly), the borrower submits a borrowing-base certificate detailing eligible AR. The lender re-sizes the available line. Over-advances (drawing more than the new eligible base supports) trigger immediate pay-down demand. This is real operational overhead — typically 4–10 hours per month for the borrower's controller.
Approval reality.
AR financing lenders underwrite both the borrower (2+ years operating, profitable, audited or reviewed financials preferred) and the receivables portfolio (customer mix, aging, concentration, historical bad debt). Approval rates lower than MCA but higher than bank term loans for the right industry fits (manufacturing, distribution, staffing, freight).
Industry fit.
AR financing fits the same B2B industries as factoring: manufacturing, distribution, staffing, freight, professional services, government contracting. Better fit than factoring when customer relationships are sensitive and notice of assignment would damage them.
Customer experience.
Customers usually never know about AR financing — payments flow to the borrower's normal lockbox; no notice of assignment. This is the major advantage over factoring for relationship-sensitive industries (consulting, premium professional services, key-account manufacturing).
The hybrid play.
A business with a $500K AR financing line and a fast $75K need (tax bill due in 5 days, draw approval requires 48 hours of paperwork) might take a small MCA for the immediate need rather than rush the borrowing-base recertification. The MCA covers the gap; the AR line continues to handle the bulk of working capital.
When AR financing is the right answer.
- 2+ years operating, B2B with sustained receivables.
- Customer concentration manageable.
- Want cheapest sustained-balance cost-of-capital.
- Want to preserve customer relationships (no notice of assignment).
- Can absorb monthly reporting burden.
When MCA is the right answer.
- Under 2 years operating, or AR financing declined.
- Need money in days, not weeks.
- B2C or cash business with no AR.
- Customer concentration too high for AR financing.
- Need is one-time, not sustained.
Common confusion. First, "AR financing is the same as factoring" — no, factoring is a sale; AR financing is a loan secured by AR. Second, "AR financing rates are quoted per month" — sometimes, but the underlying line is APR-priced. Third, "AR financing is only for big businesses" — no, specialty lenders serve $1M–$50M revenue range. Fourth, "AR financing and MCA can co-exist" — only if the MCA UCC lien is subordinated, which most AR lenders will not allow.
As of 2026-06-30, the playbook. B2B with mature AR ledger: AR financing first. MCA only for fast / one-time needs or when AR financing has been declined.
Related terms
- MCA vs. invoice factoring (detailed) — Invoice factoring advances 70–90% of invoice value at 1–4% per 30 days (12–48% effective annualized), repaid when customers pay. MCAs deliver capital against all future revenue at 50–65% APR-equivalent. Factoring is cheaper but only works if invoices exist.
- Invoice factoring — Invoice factoring is selling your unpaid invoices to a factoring company for immediate cash (typically 80-95% of invoice value). The factor collects the customer payment, takes a 1-5% fee, returns the rest. Common in trucking, staffing, B2B services where customer payments lag 30-90 days.
- Merchant cash advance (MCA) — A lump-sum advance against future revenue, repaid via fixed daily ACH or a percentage of card sales. Legally a sale of future receivables, not a loan.
- APR-equivalent — The annualized percentage rate implied by a factor-rate MCA. A 1.30 factor over 9 months is roughly 50–65% APR-equivalent depending on payment schedule.
