How Business Lines of Credit Work
By Gary Weston, Founder and CEO of Cheetah Capital Finance LLC · Updated July 20, 2026
A business line of credit is one of the most flexible financing tools available, but it is also one of the most misunderstood. Unlike a term loan, it is not a single lump sum you receive and repay on a fixed schedule. It is a revolving facility you can draw from, repay, and draw from again, similar in structure to a credit card but usually with a higher limit and a business purpose.
This guide explains how a business line of credit works, what it is typically used for, and how it compares to other financing structures.
How a Line of Credit Is Structured
A lender approves a business for a maximum credit limit. The business can draw any portion of that limit at any time, and interest is generally charged only on the amount actually drawn, not on the full limit. As the business repays what it has drawn, that amount becomes available to draw again, which is why it is described as revolving.
This is fundamentally different from a term loan, where the full amount is disbursed up front and repaid on a fixed schedule whether or not the business is using all of it.
What a Line of Credit Is Typically Used For
- • Managing cash flow gaps between receivables and payables.
- • Covering seasonal fluctuations in revenue or expenses.
- • Bridging timing gaps on a specific project or contract.
- • Providing a standing reserve for unplanned or time sensitive needs.
Because it can be drawn as needed rather than all at once, a line of credit is generally better suited to ongoing or unpredictable needs than to a single, defined purchase.
Line of Credit vs. Term Loan
A term loan is usually the better fit when a business knows exactly how much capital it needs and for what specific purpose, such as a defined equipment purchase or a planned expansion. A line of credit is usually the better fit when the amount and timing of the need are less predictable, or when the business wants access to capital without committing to a full disbursement it may not fully use.
It is common for a business to use both structures for different purposes rather than choosing one over the other entirely.
What Lenders Generally Consider
Approval and the size of the credit limit are determined by the lender, and typically involve a review of business revenue, cash flow, time in business, and credit profile. Some lines of credit are secured by business assets, while others are unsecured and rely more heavily on the overall financial strength of the business.
Using a Line of Credit Responsibly
Because a line of credit is easy to draw from, it can be tempting to treat it as a permanent source of working capital rather than a flexible tool for specific gaps. A line of credit works best when it is drawn intentionally and repaid consistently, rather than left drawn down indefinitely, which can affect both the cost of the facility and the business's overall financial position.
As with any financing decision, approval, credit limit, and terms are determined by the lender following underwriting, documentation, and verification. Understanding how the structure works before applying makes it easier to have an informed conversation about whether it fits your situation.
