Invoice Factoring vs. a Line of Credit vs. an MCA: What Each One Actually Costs You

A contractor we work with needed $40,000 to cover payroll between two invoiced jobs. His bookkeeper had heard the word “factoring” and assumed it worked like a line of credit with a different name. It does not. Three products routinely get offered for the exact same cash-flow gap, and they differ in who gets paid first, who talks to your customers, and what happens to your margin — not just in what the paperwork is called.

What each one actually is, not what it is marketed as

Invoice factoring is a sale, not a loan. Under UCC § 9-102(a)(2), an “account” is your right to payment for goods or services you have already delivered — the invoice. In a factoring deal, you sell that right to a factor at a discount, and under UCC § 9-406 the factor notifies your customer (the “account debtor”) to pay the factor directly going forward. Your customer's payment no longer touches your bank account at all. That notification is the defining mechanic of factoring, and it is also the thing most owners underestimate: your client now knows you sold their invoice.

A business line of credit is conventional revolving bank credit. You are approved for a limit, you draw against it as needed, you pay interest only on what you draw (typically priced off the prime rate, see our WSJ Prime Rate explainer), and the limit replenishes as you repay — see our comparison of term loans vs. lines of credit for how that structure plays out against a one-time loan. SBA also backs a revolving working-capital product through CAPLines for borrowers who qualify.

A merchant cash advance is neither of the above. An MCA provider advances a fixed amount against your future card or bank-deposit receipts, and you repay a fixed total (the advance plus a factor fee) via a daily or weekly ACH debit or split of card receipts. Under 12 CFR § 1002.104(b), a true MCA — structured as a sale of future receivables rather than an extension of credit — is excluded from several consumer-lending protections, which is exactly why it carries no disclosed APR the way a loan does. The FTC has pursued and won enforcement actions against MCA providers for deceptive terms and illegal collection practices, including FTC v. Yellowstone Capital and the 2022 bans on Richmond Capital's and other MCA operators' principals — not because MCAs are inherently illegal, but because the product's opacity has been a magnet for abuse.

What actually happened when small firms applied for financing in 2025

2025 Small Business Credit Survey, employer firms. Factoring is not tracked as its own category in this report — a small enough slice of SMB financing that the Fed's flagship survey folds it into “other.”

Small banks had the highest full-approval rate of any lender type the report breaks out, at 57% — one reason the line of credit below, which most often comes from a bank, tends to be the cheapest financing you can get, if you can qualify for it.

Who actually qualifies for which one

Factoring underwrites your customer's creditworthiness more than yours — a thin business credit file with a blue-chip client on the invoice can still get factored, because the factor is really betting on whether that client pays. A line of credit underwrites your business the conventional way: time in business, revenue, and credit file, which is why it consistently shows the highest full-approval rate of any financing type the Fed's own 2025 Small Business Credit Survey tracks, particularly at small banks. An MCA underwrites almost nothing beyond recent bank or card deposit volume, which is exactly why it is the fastest to fund and the most commonly reached for by businesses that could not get approved for the other two.

The cost difference that does not show up on a rate sheet

A line of credit has a transparent, comparable cost: an interest rate tied to a published index, disclosed before you sign. Factoring's cost is a discount rate taken off each invoice — cheaper the faster your customers actually pay, more expensive the longer invoices age, and it scales with volume rather than being a flat number you can quote in the abstract. An MCA's cost is the one most owners get wrong: a quoted “1.3 factor rate” sounds like 30%, but because the advance is typically repaid in a matter of months rather than a year, the annualized cost is routinely far higher than either a line of credit or factoring — the reason regulators keep returning to this product is precisely that the sticker price and the real cost are so far apart.

The relationship cost factoring has and the others do not

Only factoring puts a third party directly in contact with your customers. That is not automatically a dealbreaker — some factoring relationships are disclosed to clients as routine and cause no friction — but it is a decision you are making about your customer relationships, not just your balance sheet, and it is irreversible once the notice under UCC § 9-406 goes out. A line of credit and an MCA both stay entirely behind the scenes; your customers never know either exists. If you are weighing whether a “non-recourse” factoring deal still leaves you personally exposed if a client simply does not pay, read our piece on the validity guaranty before signing — “non-recourse” almost never means what it sounds like it means.

How to actually decide

• Choose factoring if: your cash-flow gap is specifically unpaid invoices from creditworthy customers, you can accept your customer being notified, and your own business credit file is thinner than your client roster.
• Choose a line of credit if: you qualify for one. It is the cheapest, most transparent, and most reusable of the three, and the gap is general working capital rather than a specific batch of invoices.
• Treat an MCA as a last resort, not a first call. It is the fastest to fund and the easiest to qualify for, which is exactly why it is also, dollar for dollar, usually the most expensive — run the real annualized cost before you sign, not the factor rate alone.
• Check what is already filed against your assets before adding any of the three. A UCC blanket lien from an existing facility can complicate layering a new one on top — see our guide to what a UCC-1 blanket lien actually blocks.

None of the three is categorically wrong — each is a legitimate, regulated-to-varying- degrees tool for a specific version of the same problem: cash is owed to you later than you need it now. The mistake is letting the fastest-closing option (almost always the MCA) win by default because nobody ran the comparison. If you want that comparison run against your actual invoices, bank statements, and credit file, schedule a consultation and we will tell you honestly which of the three, if any, actually fits.
