How a business line of credit works
A business line of credit is a revolving credit facility — you're approved for a maximum credit limit, and you draw against it whenever you need capital. You only pay interest on the amount you've actually drawn, not the full credit line. As you repay what you've drawn, that capacity becomes available again.
Think of it like a credit card for your business, but with significantly lower interest rates and structured for business purchases rather than consumer spending. You can draw $10,000 today, repay it next month, and that $10,000 is back in your available credit immediately — no new application required.
When a line of credit is the right choice
Lines of credit are best when your funding needs are unpredictable, recurring, or both. The classic use case is bridging the gap between when you pay vendors and when customers pay you — known as a "working capital cycle." Other common scenarios:
- Seasonal cash flow management for retail, hospitality, or service businesses
- Covering payroll during slow weeks or while waiting on large invoices
- Capturing time-sensitive opportunities (inventory deals, supplier discounts) without re-applying for a loan each time
- Maintaining a financial safety net for unexpected expenses
- Funding small recurring projects rather than one large initiative
If you have a single, defined use of funds and a clear repayment plan, a term loan is usually a better fit — slightly lower rate, simpler structure, no temptation to overdraw.
The math: why lines of credit save money for recurring needs
Imagine you need access to $50,000 over the course of a year, but you'll only draw about $15,000 at any given time. With a term loan, you'd take the full $50,000 up front and pay interest on the entire balance for the full term — even on the $35,000 you don't actually need at any given moment.
With a line of credit, you'd only ever owe $15,000 at a time. At the same APR, you'd pay roughly one-third the interest of the term loan. For revolving needs, the line of credit is a clear winner.
The trade-off: lines of credit usually have stricter qualification requirements than term loans. Lenders want to see at least 12 months in business, $150K+ in annual revenue, and a personal credit score of 600 or better. Some require higher.
Secured vs. unsecured lines of credit
Most small business lines of credit under $250K are unsecured — meaning you don't pledge specific collateral, though the lender will typically file a UCC blanket lien on business assets. Larger lines may require collateral (real estate, equipment, or accounts receivable) in exchange for higher limits and lower rates.
For most small businesses, unsecured is the right path. The collateral requirements for secured lines add complexity and time that isn't worth it for sub-$250K facilities.
What lenders look for
Line of credit underwriting is similar to term loan underwriting but slightly more conservative because the lender is committing to extend credit on demand for an extended period. Key factors:
- Cash flow consistency — lenders want to see predictable monthly deposits, not big swings
- Credit history — both personal and business; 600+ personal credit is the typical floor
- Time in business — 12+ months is standard; 24+ unlocks better terms
- Existing debt obligations — too much existing debt limits the size of new credit
- Industry — some industries are easier than others (B2B services rank ahead of restaurants, for example)
Typical terms and rates
Business lines of credit through TurboFunding range from $10K to $500K. Draw periods are typically 12-24 months, with most lines being renewable annually if your business remains in good standing. Rates vary based on borrower profile but generally range from 1% per month (for the strongest profiles) to 3-4% per month (for higher-risk borrowers). Always ask for the APR equivalent — monthly rates can obscure the true cost of capital.
There's typically no fee to draw, no minimum draw amount, and no prepayment penalty. You only pay interest on what you've drawn.
How draws and repayments actually work
Once your line of credit is approved and set up, you can request a draw at any time through an online portal, an app, or by calling your funding specialist. Drawn funds typically arrive in your business bank account within hours via ACH (standard) or same-day via wire (small fee may apply).
Repayment is similarly flexible. Most lines of credit have a minimum monthly payment based on your current balance — typically interest plus a small principal portion. You can pay more than the minimum at any time without penalty, and as you repay principal, that capacity becomes available to draw again. This is the "revolving" part of revolving credit.
Some lines of credit also have an annual draw fee or a small monthly maintenance fee on the unused capacity. These vary by lender and should be clearly disclosed up front. Always ask about these fees before signing — they affect the true cost of having the line available.
Real-world line of credit scenarios
The cash flow smoother. A $200,000-revenue B2B service business has 60-day payment terms with most clients, meaning there's a constant gap between when payroll is due and when invoices get paid. A $50,000 line of credit covers the gap. The business draws $20-30K mid-month, repays it when client invoices clear, and the cycle repeats. Effective interest cost: a few hundred dollars a month for stress-free payroll.
The opportunity capture line. A specialty foods retailer has a line of credit ready for moments when wholesalers offer steep discounts on close-out inventory. The retailer can move fast on opportunities that competitors miss because they're stuck waiting for loan approval.
The seasonal business safety net. A landscaping company does 70% of revenue in 6 months. The line of credit covers operating expenses during the slow months and gets paid down when the busy season hits. This is a textbook line-of-credit use case — predictable but variable cash flow.
What can damage your line of credit
Lines of credit aren't permanent commitments — they get reviewed periodically (typically annually) and can be reduced or pulled entirely if your business profile deteriorates. Things that put your line at risk:
- Maxing out the line and only paying minimums for extended periods (signals you're reliant on the credit)
- Late or missed payments
- Personal credit score drops
- Significant revenue declines
- Bouncing payments due to insufficient funds
The borrowers who keep their lines healthy treat the line as a tool, not a crutch — drawing when needed, paying back promptly, and keeping their business fundamentals strong.
Why TurboFunding for a line of credit
Lines of credit have wider variance in terms than almost any other small business product. The same borrower can get dramatically different offers from different lenders — sometimes 2-3x apart on effective cost. That's why we work with multiple lenders and route your application based on which one is most likely to offer competitive terms for your specific profile.
Apply in 5 minutes, get a real answer the same business day, and have your line of credit available within 2-5 business days.
