Founder Finance #005: The First Time I Used a Business Line of Credit

A business line of credit is one of the most useful financial tools a founder can have — and one of the most misunderstood. Most founders either avoid it entirely out of caution, or reach for it at the wrong moment for the wrong reasons. I did the latter the first time. Here’s what I learned.

What a Business Line of Credit Actually Is

A business line of credit is a revolving credit facility — a pre-approved amount you can draw from, repay, and draw from again. You only pay interest on what you actually use, not on the full credit limit. It is not a loan. It is access to capital that you deploy when you need it.

Think of it as a financial buffer between your business and the moments when cash flow doesn’t match timing — a client pays late, an opportunity requires upfront investment, or an unexpected expense arrives before revenue does.

The Case Study

How Lines of Credit Are Typically Structured

• Credit limit — the maximum you can draw at any time
• Draw period — how long you can access funds (often 12–24 months, then renewed)
• Interest rate — applied only to the outstanding balance, not the full limit
• Draw fees — some lenders charge a fee each time you draw, separate from interest
• Maintenance fees — some lines carry annual or monthly fees whether you use them or not
• Personal guarantee — common for small business lines, especially without established business credit

When a Line of Credit Makes Sense

• Bridging a timing gap between work delivered and payment received
• Covering predictable seasonal cash flow dips
• Funding a time-sensitive opportunity that will generate returns before the draw period ends
• Maintaining operational stability during a growth phase with uneven revenue

When It Doesn’t

• Funding ongoing operating losses — a line of credit is not a substitute for a viable business model
• Making large capital purchases — a term loan is usually better structured for that
• Covering expenses you can’t clearly see a path to repaying within the draw period

What I’d Do Differently

• Apply for the line when the business looks its strongest — not when cash is tight
• Read the draw fee structure before the moment of need. Some lines are expensive to actually use.
• Keep the utilization low even when drawing — high utilization can affect business credit scores
• Treat repayment as the first priority when cash arrives — not an option
