The job a credit line does
A credit line gives you a pool of approved funds you can tap when cash runs short. You pay interest only on the amount drawn, and repaid balances become available again.
Think of it as a reserve, not a lump sum. A term loan hands you the full amount on day one and you pay interest on all of it. A line of credit sits in the background until a bill arrives before the customer payment does.
That difference matters. If your business has a steady flow of work but uneven timing, a revolving line matches the problem. If you need one big check for one big purchase, a different product usually fits better. Our comparison of a term loan vs. a line of credit walks through the tradeoff.
Good uses: short, repeating gaps
The best uses are payroll timing, inventory restocking, supplier deposits, and covering slow-paying customers. Each one gets repaid by sales the money itself helps produce.
A good use has two features. It is short, and it pays itself back from revenue within weeks or a few months. Common examples:
- Payroll timing. Wages are due Friday, a large customer pays the following Wednesday.
- Inventory. You buy stock ahead of a busy season and repay as it sells.
- Supplier deposits and early-pay discounts. Paying a vendor early can save money if the discount exceeds your cost of borrowing.
- Slow receivables. You delivered the work but the invoice runs 45 days.
- Small surprises. A repair, a permit fee, a rush order.
Here is an illustrative example. You draw $15,000 to buy inventory, and it sells for $24,000 over six weeks. After repaying the draw and its cost, the line paid for itself. That is the pattern to look for.
Poor uses: long-lived assets and permanent losses
Do not use a revolving line to buy equipment that lasts years, to buy real estate, or to cover a business that loses money every month. The repayment horizon does not match.
A line is built to be repaid and drawn again. If you spend it on something that takes years to pay back, the balance never clears, and your cushion is gone when you need it most.
- Long-lived equipment. A term loan or equipment financing spreads cost over the useful life of the asset.
- Ongoing losses. Borrowing to cover a business that spends more than it earns only delays the problem.
- Personal spending. Mixing it with business money muddies your books and your taxes.
A simple test: if you cannot name the sales that will repay the draw, wait.
How to size a line to your actual needs
Size a line to your worst normal gap, not your biggest dream. Add up the longest stretch between spending and collecting, then add a modest buffer.
Look at your last twelve months. Find the lowest point in your bank balance and the biggest swing between paydays and collection days. That swing is your core need.
- List fixed outflows for a typical month: payroll, rent, supplier bills.
- Note how many days pass before customer cash arrives.
- Multiply daily outflow by the days of gap.
- Add 15 to 25 percent for surprises.
Asking for far more than that adds no value if you will not use it. Some lines carry fees tied to the limit or to activity, so read the terms. We cover that in business line of credit fees.
What a line costs and how to keep it cheap
You pay for the money you use, usually plus any fees in the agreement. The cheapest habit is to draw small, repay fast, and never leave a balance sitting idle.
Pricing varies by funder and by file, so compare the total cost of a draw, not just the headline rate. Ask for the repayment schedule, any draw or maintenance fees, and how the cost is expressed. Then convert it to dollars for the amount and time you expect to use.
Illustrative example: you draw $10,000 and repay it in 8 weeks. If the total cost for that draw is $500, you paid 5 percent of the draw for eight weeks of access. If the sales it produced are bigger than that, the draw earned its keep. How interest works on these products is explained in how interest works on a business line of credit.
Habits that keep a line useful
Use it for planned gaps, repay from the sales it supports, and keep some availability untouched. A line you max out stops being a safety net.
Treat the line like a tool with a job. Write down what each draw is for and what incoming money will repay it. Review it monthly. If you keep drawing and the balance keeps rising, the line is covering a deeper problem, and it is time to look at margins, pricing or a different structure.
Also keep the line active in good times. Funders may adjust or close dormant lines, and having one in place before a crunch beats applying in the middle of one. Our guide to managing a business line of credit covers the routine in detail.

Frequently asked questions
What is a business line of credit used for?
It covers short-term, repeating cash needs such as payroll timing, inventory, supplier deposits and slow-paying customers. You draw what you need and repay it.
Can I use a line of credit to buy equipment?
You can, but it is rarely the best fit. Equipment lasts years, so financing with a repayment schedule that matches its life usually costs less and protects your cash buffer.
Do I pay interest on the whole credit limit?
Generally you pay on what you draw, plus any fees stated in the agreement. Read the terms to confirm how cost is charged.
How fast can I draw from a line of credit?
After the line is set up, draws through ROI Funder's network typically take about 24 to 72 hours.
