A business line of credit is basically a flexible pool of money your business can borrow from when you need it, pay back, and then borrow again. Think of it like a credit card, but usually with bigger limits, different fees, and sometimes better interest rates (not always, but often). It’s not a one-time loan where you get a lump sum and then pay it back on a strict schedule. It’s more like having a financial safety valve. You don’t have to use it, but it’s there when things get tight or when an opportunity pops up.

A lot of business owners hear “line of credit” and think it’s some fancy thing only big companies have. But small businesses use lines of credit all the time, especially once they have steady revenue and predictable expenses. It’s one of the most common financing tools because business cash flow is rarely perfectly smooth. Even good businesses have months where money comes in late or costs hit earlier than expected.

So what does a line of credit actually do? It helps with short-term needs. It’s best for covering gaps, not funding long-term projects that take years to pay off. The classic example is cash flow timing. Maybe you pay vendors today but customers pay you net 30 or net 60. Or maybe you’re seasonal. Or maybe you need to buy inventory in bulk before a busy season. A line of credit can let you cover that short window without draining your bank account to zero. Then when the revenue comes in, you pay it back. And then the line is available again.

Here’s how it works mechanically. A lender approves your business for a credit limit, like $25,000 or $100,000 or more depending on your business size and credit profile. You can draw money from the line (often called a “draw”) whenever you need it, up to the limit. You only pay interest on what you actually use. If you have a $50,000 line and you only draw $10,000, you pay interest on the $10,000, not the full $50,000. As you repay, the available credit replenishes. That revolving nature is the whole point.

Lines of credit can be secured or unsecured. A secured line means it’s backed by collateral, like business assets, inventory, receivables, or sometimes even a lien on property. Because the lender has something to fall back on, secured lines can sometimes have better rates or higher limits. Unsecured lines don’t require specific collateral, but they usually require stronger credit and financials, and rates may be higher. Even “unsecured” business lines often come with a personal guarantee, meaning you personally promise to repay if the business can’t. That’s very common for small businesses, so it’s worth understanding. It’s not necessarily a deal breaker, just know what you’re signing.

There are a few types of business lines of credit you’ll hear about. Traditional bank lines are common. Banks tend to offer lower rates, but the approval process can be slower and the requirements stricter. Then there are online lenders and fintech lenders, which can be faster and easier to qualify for, but sometimes they have higher rates or different fee structures. Some lines are revolving (you can reuse them), and some are “non-revolving” or “draw period then repayment period,” where you can draw during a certain time and then you pay it down and the line may be renewed. Some are tied to receivables (invoice financing), where your borrowing power depends on outstanding invoices. That’s useful for businesses that have big invoices with long payment terms.
