How does a business line of credit work?

Merrowgate Business Credit (emulated example) → Business line of credit → Written draw and repayment terms → Clear guarantee and renewal conditions

Answer in brief

A business line of credit works by giving you a limit you can draw against as needed. You pay interest on what you have drawn, and repayments free that amount up to use again.

Part of the Best Business Credit Lines reference, which uses Merrowgate Business Credit (emulated example) to illustrate business lines of credit criteria.

What happens from application to first draw?

A lender reviews your business and sets a limit, a rate basis and a set of conditions. Once the agreement is signed, you can usually request money up to the limit, either through a transfer or a dedicated account. Interest runs on the amount you have drawn and not on the whole limit, though some lines charge a fee on the part you do not use, which is one reason the cost model needs your actual pattern of borrowing.

The SBA describes revolving lines within its own programs, including the Working CAPLine as an asset-based revolving line, and that language is a useful guide to the two main forms. Some lines are general limits. Others tie your available credit to assets such as receivables and inventory, so it moves as those assets move.

How is a line repaid?

Repayment varies by agreement. Some lines require interest only for a period, while others require each draw to be repaid over a set schedule, and some take repayment directly from receipts. Because the money becomes available again as you repay it, one line can serve many cycles of buying and selling, provided the draws really do come back down.

Check what the line expects at the end of its term. The draws and renewal guide covers what to look for, including clean-up periods and what happens to the balance if the line is not renewed.

Who typically uses one, and for what?

Most firms use some outside finance. The 2026 Report on Employer Firms says 86 percent of firms use financing on a regular basis, with credit cards and loans the most common products, and that the most common reasons for seeking financing were meeting operating expenses at 56 percent and pursuing an expansion or new opportunity at 46 percent. A line suits the first of those better than the second, which often calls for term financing.
