Use a line when borrowing needs rise and fall
A revolving line of credit lets a business borrow, repay and borrow again up to an approved limit, subject to the agreement. That makes it better suited than a term loan for short duration working capital needs such as payroll before receivables arrive, seasonal inventory purchases, contract mobilization and timing gaps between supplier payments and customer collections. The key feature is reuse. If a company draws $150,000 from a $300,000 line and later repays $100,000, available credit can generally rise again by that amount if all borrowing conditions remain satisfied.
The line should track an operating cycle, not become permanent debt by accident. If a business carries the full balance every day for two years and cannot materially reduce it from normal collections, the supposed temporary need may actually be a long term capital deficit. Banks often look for evidence that a working capital line turns over. Borrowers should monitor average utilization, peak draws and the number of days the line reaches a low balance. Those measures reveal whether the facility is supporting working capital or masking an undercapitalized business.
Distinguish a committed limit from usable availability
The stated line amount is not always the amount a company can draw today. Some facilities are simple revolving lines with a fixed commitment, while asset based structures calculate availability from eligible receivables, inventory or other collateral. A $1 million facility with an 80 percent advance rate on eligible receivables does not create $1 million of immediate cash if the borrowing base contains only $600,000 of qualifying invoices. In that example, gross availability might begin around $480,000 before reserves or outstanding borrowings.
Eligibility rules can exclude aged invoices, foreign receivables, concentrations to one customer, disputed amounts or receivables from affiliates. Inventory may receive a lower advance rate because liquidation values are less predictable. Ask how frequently the borrowing base must be reported and what happens when collateral values fall. A line that looks generous at approval can tighten quickly if a major customer becomes past due. Companies using borrowing base facilities need reporting systems that are accurate enough to support frequent calculations without disrupting operations.
Price the facility around actual utilization
Line of credit pricing can include interest on drawn balances plus commitment, unused line, maintenance or annual fees. A business that expects to use only 25 percent of a large facility should therefore compare the full annual cost of keeping the line available, not just the rate charged on borrowings. Variable pricing is common and can move with a base rate. SBA 7(a) Working Capital Pilot lines, for example, remain subject to SBA maximum rate rules and can provide monitored lines of credit up to $5 million for eligible borrowers.
Run the cost at several utilization levels. Suppose a company has a $500,000 line, expects average borrowing of $175,000 and pays a facility fee in addition to interest. Compare the annual dollars paid at that average balance with a smaller commitment that has a lower fee burden. Then test the opposite scenario, when a large order suddenly requires $400,000. Paying a modest fee for unused capacity can be rational if the extra liquidity protects a valuable contract. The correct facility size balances cost against the value of dependable access.
Plan for renewal and maturity before the line expires
Many bank lines are reviewed annually or have a stated maturity date. Renewal is not automatic. The lender may request updated financial statements, tax returns, borrowing base reports, covenant calculations and information about ownership or industry changes. A line that is essential to payroll should never be treated as permanent cash if the company has no backup plan for a nonrenewal or reduced commitment. The operational risk is highest when the business relies on the entire facility near the renewal date.
Start the renewal process well before maturity and track what the bank will require. If a $750,000 line matures December 31, waiting until mid December to deliver financials leaves little room to resolve questions. A disciplined borrower may begin in September, update projections and document why the requested limit still matches the working capital cycle. If the business has grown materially, ask whether the line should expand. If utilization has declined, a smaller commitment may reduce cost without weakening liquidity.
Treat covenants and reporting as operating requirements
Credit lines often come with financial covenants, reporting deadlines and restrictions on additional debt, distributions or asset sales. These terms are not merely legal language. A breach can stop further draws, trigger default remedies or force a waiver negotiation even when the business is still making payments. Finance teams should put covenant definitions into their monthly close process and calculate them using the exact formula in the credit agreement rather than a similar internal metric.
For example, a lender may require a minimum debt service coverage ratio or maximum leverage measure using specifically defined earnings and debt. If management calculates a familiar EBITDA ratio while the agreement excludes certain add backs, the company can believe it is compliant when it is not. Build a covenant calendar that identifies reporting due dates, certificate requirements and responsible staff. The best time to discuss a potential breach is before it occurs, when management can present updated forecasts and corrective actions rather than asking for relief after a deadline is missed.
Keep unused capacity as a liquidity reserve
A line is most valuable when some capacity remains available for an unexpected operating need. Running continuously at 95 to 100 percent utilization leaves little protection if a customer pays late, inventory costs rise or a contract requires more upfront spending than forecast. The company may technically have a credit line while having almost no liquidity. Management should set an internal minimum availability target based on payroll, supplier obligations and the volatility of collections.
A practical approach is to compare unused availability with one or two critical cash outflows. If weekly payroll and taxes total $90,000, a company with only $20,000 of remaining line capacity is exposed even if receivables are expected next week. The solution may be to reduce draws, increase the facility, improve collections or add equity rather than simply seeking another short term loan. A credit line works best as a bridge through a predictable cash cycle, with enough headroom to absorb normal surprises.
Editorial Verdict
Measure a credit line by flexibility, not the headline limit.
A line of credit should expand and contract with the working capital cycle. Focus on usable availability, borrowing base rules, renewal risk, fees, covenants and unused capacity. If the balance never comes down, the business may need permanent capital or a term structure rather than a larger revolving line.
