How Business Lines of Credit Work

A business line of credit is a flexible financing tool that gives a business access to funds up to an approved limit. Unlike a term loan, which delivers a single lump sum, a line of credit is revolving — you draw what you need, repay it, and draw again. It's designed for ongoing or unpredictable working-capital needs.

The Revolving Mechanic

Think of a line of credit like a credit card for your business, but typically with lower costs and larger limits. You're approved for a maximum amount — say, $100,000. You don't receive that money all at once. Instead, you draw from it as needed: $20,000 for inventory one month, $10,000 to bridge a receivable the next. As you repay each balance, that credit becomes available again. The same line can be reused repeatedly for as long as it's open.

You Pay for What You Use

One of the main advantages of a line of credit is that interest is typically charged only on the amount you actually draw — not the full approved limit. If you have a $100,000 line but only draw $20,000, you generally pay interest on $20,000. The unused $80,000 sits available without accruing interest (though some lines carry maintenance or draw fees).

Secured vs Unsecured

Lines of credit may be secured or unsecured. An unsecured line doesn't require collateral but typically depends on stronger credit and financials. A secured line may be backed by accounts receivable, inventory, or other business assets, and can offer a higher limit or lower rate. The structure depends on the provider and the business's qualification.

Qualification Factors

Qualification for a business line of credit commonly considers:

• Time in business (often 1–2+ years)
• Annual and monthly revenue
• Consistency of bank deposits
• Personal and/or business credit
• Existing obligations and debt service
• Industry and cash-flow stability

When a Line of Credit Fits

A line of credit is well suited to situations where capital needs are ongoing or unpredictable:

• Bridging the gap between paying suppliers and collecting receivables
• Seasonal inventory purchases before peak sales
• Covering payroll during a slow cycle
• Handling unexpected repairs or expenses
• Taking advantage of time-sensitive opportunities

For a one-time, defined capital need, a term loan is often a better fit. To compare, see our article on MCA vs line of credit and our MCA vs term loan comparison.
