A business line of credit gives a company access to a set amount of funds that it can draw from as needed, repay, and draw from again, rather than receiving a single lump sum like a traditional term loan. This flexibility makes lines of credit a popular tool for managing cash flow, covering short-term expenses, and handling unexpected costs without having to apply for new financing every time a need arises.
How a Business Line of Credit Works
Once approved, a business is given a credit limit — the maximum amount it can borrow at any one time. The business can draw any amount up to that limit, repay it on a schedule set by the lender, and then draw again as needed, similar in structure to a credit card. Interest is generally charged only on the amount actually drawn, not on the full available credit limit, which is one of the key differences between a line of credit and a traditional term loan where the full amount is disbursed and begins accruing interest immediately.
Lines of credit can be either secured or unsecured. A secured line is backed by business collateral, such as inventory, equipment, or accounts receivable, and may offer a higher limit or lower rate as a result. An unsecured line does not require specific collateral but often comes with a lower credit limit and may require a personal guarantee from the business owner.
Common Uses for a Business Line of Credit
Businesses commonly use lines of credit for:
- Managing seasonal cash flow gaps, such as covering payroll and expenses during slower sales periods
- Bridging the time between invoicing and payment, especially for businesses with long customer payment cycles
- Covering unexpected expenses, like emergency repairs or urgent inventory needs
- Taking advantage of short-term opportunities, such as a bulk purchase discount from a supplier
Because of this flexibility, lines of credit are generally better suited to ongoing or unpredictable funding needs rather than a single large, planned purchase, which is often better financed with a term loan or equipment financing.
Costs and Fee Structures
The cost of a business line of credit typically includes:
- Interest charges on the outstanding drawn balance, which may be fixed or variable depending on the lender
- Draw fees, charged each time funds are withdrawn, on some lines of credit
- Maintenance or annual fees, charged simply for keeping the line open, whether or not it's used
- Late payment fees, if scheduled repayments are missed
Because pricing structures vary significantly between banks, credit unions, and online lenders, it's worth comparing the total cost of a line of credit — not just the headline interest rate — across multiple offers.
Qualification Requirements
Lenders evaluating a business line of credit application typically consider:
- Time in business, with many traditional bank lenders preferring businesses that have operated for at least one to two years, though some online lenders work with newer businesses
- Revenue and cash flow, since consistent income helps demonstrate the ability to repay draws
- Business and personal credit history, particularly for smaller businesses where the owner's personal credit is closely tied to the business's borrowing profile
- Collateral, for secured lines of credit
Businesses applying for a line of credit are generally asked to provide financial statements, bank statements, tax returns, and other documentation similar to what's requested for other types of business financing; a general overview is available in documents needed to apply for a loan.
Comparing Lines of Credit to Other Financing Options
A business line of credit is one of several financing tools available to small businesses, each suited to different needs:
- SBA loans tend to work better for larger, longer-term financing needs, such as expansion or major equipment purchases, and often come with government-backed guarantees that can improve terms.
- Equipment financing is generally a better fit when the funding need is tied to a specific, identifiable asset purchase.
- Merchant cash advances are sometimes used by businesses that can't qualify for a traditional line of credit, though they typically carry substantially higher costs.
Managing a Line of Credit Responsibly
Because a line of credit is revolving debt, it's important to track outstanding balances relative to the credit limit and to avoid relying on it as a permanent source of working capital rather than a short-term bridge. Consistently carrying a high balance relative to the limit can also affect a business's credit profile in ways similar to how credit utilization affects personal credit scores. Reviewing overall business debt levels periodically, potentially alongside tools like a debt consolidation calculator when multiple forms of business debt are in play, can help keep borrowing costs manageable over time.
