Invoice Factoring vs. a Bank Line of Credit: I Ran the Numbers

Published October 1, 2026

This is the comparison every growing business eventually makes, and most of the articles about it are written by companies selling one of the two products. So let me do it with a calculator mindset instead: one concrete scenario, both costs annualized, and then the trade-offs that the numbers do not capture.

The scenario

You run a small services business. You just delivered $80,000 of work, invoiced on Net 45 terms, and you need $68,000 in cash now to make payroll and pay subcontractors. Two options:

Option A: factor the invoice. A factor offers an 85 percent advance at a 2.5 percent fee per 30 days, recourse. You receive $68,000 on day 1. Your customer pays on day 45.

Option B: draw on a bank line of credit. You have a $100,000 revolving line at 10.5 percent APR. You draw $68,000 on day 1 and repay it on day 45 when the customer pays.

The math

Factoring: the fee is 2.5 percent per 30 days over 45 days, which is 3.75 percent of the $80,000 face value: $3,000. You paid $3,000 for $68,000 over 45 days. Annualized: ($3,000 / $68,000) x (365 / 45) = roughly 35.8 percent APR.

Line of credit: $68,000 at 10.5 percent APR for 45 days costs $68,000 x 10.5% x (45 / 365) = roughly $880 in interest. Some lines add an origination or annual fee; spread over a year of regular use, even a $500 annual fee keeps this far below the factoring cost.

The line of credit is about one-quarter the cost. This is not a close call on price, and it rarely is. Bank lines at 7 to 12 percent APR beat factoring decisively whenever a business qualifies for both.

So why does anyone factor?

Because price is only one dimension, and for many businesses the other dimensions matter more:

Qualification. A bank line requires credit history, profitability, time in business, and often collateral or a personal guarantee. Factoring underwrites your customers, not you. Startups, businesses with thin credit, and companies growing faster than a bank will lend can factor invoices from creditworthy customers when no bank would return their call.

Speed. A factoring line can be set up in a week or two, with funding 24 to 48 hours after that. A bank line often takes a month or two of underwriting. When payroll is Friday, speed has a value the APR does not capture.

Scaling. A line of credit has a fixed limit; getting it raised takes another round of underwriting. Factoring scales with your sales automatically: more invoices means more available cash, no renegotiation required.

No debt. Factoring is a sale of receivables, not borrowing. For businesses that want to keep debt off the balance sheet, or owners who do not want to personally guarantee a line, that distinction is worth something.

The costs the APR misses

Factoring has soft costs a line of credit does not. The factor typically contacts your customers to verify invoices and collect payment, which inserts a third party into your client relationships. Some customers do not mind; some read it as a signal that you are short on cash. Non-notification arrangements exist, where you keep handling collections, but they cost more.

Factoring contracts also carry structure a line does not: minimum volume commitments, concentration limits (no single customer over a set share), and recourse clauses that can push unpaid invoices back onto you. A line of credit is simpler to live with once you have it.

My honest take

If you can get a bank line of credit at a reasonable rate, get it. Use it as your foundation for planned working capital. Then use factoring strategically: for growth spurts that exceed your line, for seasonal peaks, or for that one giant invoice you cannot afford to wait on. The businesses that overpay for factoring are usually the ones using it as their only tool instead of as a complement.

And if you cannot yet qualify for bank credit, factor with your eyes open. Convert every quote to an effective APR, watch the recourse clause, and treat the cost as the price of access while you build the track record that gets you the cheaper line. That is a legitimate strategy. Paying 35 percent APR forever because nobody ran the numbers is not.

Frequently asked questions

Can I use factoring and a line of credit at the same time?

Often yes. Many businesses factor slow-paying invoices while keeping a line for other short-term needs. Check both agreements for restrictions: some factoring contracts claim a blanket lien on receivables that can conflict with a bank's collateral position.

Does factoring hurt my credit score?

Factoring approval is based mainly on your customers' creditworthiness, so it typically involves less scrutiny of your own credit than a loan application. It does not build your business credit history the way a responsibly managed line of credit does.

Which is faster to set up?

Factoring, usually. Expect a week or two for a factoring line versus a month or more for a bank line of credit, depending on the lender and the complexity of your financials.
