Invoice factoring turns unpaid business-to-business invoices into cash by selling them to a factor, which collects from your customer, so approval leans on their credit. A business line of credit is a revolving limit you borrow against and repay yourself, approved on your own revenue and credit. Factoring fits slow-paying customers; a line fits uneven but creditworthy cash flow.
What is the difference between invoice factoring and a line of credit?
The difference is what you are selling or borrowing against. With invoice factoring, you sell specific receivables: the factor advances most of an invoice’s value up front, collects the full amount from your customer, then releases the remainder minus its fee. With a business line of credit, you borrow against a limit set from your whole business — revenue, deposits, time in business and credit — and you repay the lender yourself.
Both exist to solve the same problem: money that is earned but not yet in the bank. In the Federal Reserve Banks’ 2025 Report on Employer Firms, 51% of small employer firms named uneven cash flows as a financial challenge and 56% named paying operating expenses. Factoring and a line of credit are the two most direct tools for that gap, but they are built for very different businesses.
How do factoring and a line of credit compare side by side?
Side by side, factoring is easier to qualify for and grows with your sales, while a line of credit is usually cheaper and leaves your customer relationships untouched.
| Invoice factoring | Business line of credit | |
|---|---|---|
| What it is | A sale of specific invoices | A revolving loan |
| Approval leans on | Your customers’ creditworthiness and invoice quality | Your revenue, bank deposits, time in business and credit |
| Who collects | Usually the factor collects from your customer | You collect; you repay the lender |
| How the amount grows | With every new invoice to an approved customer | Fixed limit until the lender reviews and raises it |
| How cost works | A fee per invoice that grows the longer the customer takes to pay | Interest on what you draw, plus any draw or maintenance fees |
| Works for | B2B and government receivables only | Any business model, including cash and card sales |
The cost difference is structural rather than fixed. A factoring fee that is charged for each period an invoice stays open makes a slow payer expensive, while a line charges only for the days you actually have the money out. For a business with solid credit and predictable collections, that usually tips the math toward the line — the factoring premium buys approval and speed, not a lower price.

When does invoice factoring beat a line of credit?
Factoring wins when your customers are stronger borrowers than you are, or when sales are growing faster than any fixed limit would allow.
Take a two-year-old staffing agency billing $120,000 a month to three hospital clients on net-45 terms. It pays its temps weekly, so at any moment it is carrying roughly six weeks of payroll before the first invoice clears. A bank may decline a line for a young company with thin margins — but the hospitals are excellent credit, and a factor underwrites them. If the factor advances, for illustration, 80% of each invoice, the agency unlocks $96,000 against a single month’s billing, and when it signs a fourth client the funding grows automatically. Government contractors are a similar case: under Federal Acquisition Regulation Subpart 32.9, the government’s standard due date is 30 days after it receives a proper invoice, which makes federal receivables predictable and easy for factors to fund.
Factoring is also the more forgiving option for owners with credit problems, because the question underwriters ask is whether your customer will pay, not whether you have a long credit history. Our guide to the best invoice factoring companies compares how factors price and structure that risk.
When is a line of credit the better choice, and can you use both?
A line of credit is the better choice when your credit and revenue already qualify, when you sell to consumers rather than businesses, or when you would rather your customers never deal with a third party.
A line covers costs that have nothing to do with invoices — a repair, a slow month, a tax payment — and nobody contacts your customers. That control matters to firms whose client relationships are the business. If you want invoice-based money without the collection step, invoice financing keeps you in charge of collections.
You can use both, but the paperwork has to line up. A factor typically needs a first-priority claim on the receivables it buys, while many lines of credit are secured by a blanket lien on all business assets, receivables included. Running both usually means the lender agreeing to carve out or subordinate its claim on the factored invoices, so disclose any existing financing up front.
