Business Line of Credit: What It Covers and When to Use It

Your supplier just offered a bulk discount that would save you $15,000 over the quarter, but the payment is due in 48 hours and your receivables won't clear for another three weeks.

An unsecured business line of credit functions like a pre-approved overdraft facility that you can draw from and repay as often as needed. You're approved for a set limit, access funds when required, and only pay interest on the amount you're actively using. Once you repay any portion, that credit becomes available again without needing to reapply.

How a Line of Credit Differs from a Term Loan

A term loan gives you a lump sum upfront that you repay in fixed instalments over a set period, whether you need the full amount immediately or not. A line of credit gives you access to funds that you can draw down, repay, and redraw as your cashflow demands change.

Consider a manufacturing business that needs to purchase raw materials quarterly based on order volumes. With a $200,000 line of credit, they might draw $80,000 in March when orders spike, repay $60,000 in April as invoices clear, then draw $120,000 in May for a larger production run. They only pay interest on the outstanding balance each day, not on the full $200,000 limit.

This structure works when your funding needs fluctuate. If you need a fixed amount for a specific purchase like new equipment, a term loan through equipment finance typically offers lower rates because the lender knows exactly what they're funding and when they'll be repaid.

When Cashflow Gaps Justify This Type of Funding

Businesses with reliable revenue but uneven payment cycles benefit most from revolving credit facilities. If your customers pay on 60-day terms but your suppliers require payment within 14 days, you're constantly bridging a 46-day gap.

Retailers preparing for seasonal peaks face similar challenges. A homewares business might need to purchase $150,000 in inventory during August and September for the Christmas period, knowing they'll turn that stock into cash by January. Rather than tying up capital or extending supplier terms at unfavourable rates, they draw from their line of credit, pay suppliers promptly to capture early payment discounts, then repay the facility as sales convert to revenue.

Service businesses managing project-based work often use this funding type to cover wages and operating costs between milestone payments. Construction firms, consulting agencies, and IT contractors all experience periods where outgoing expenses precede incoming payments by weeks or months.

How Approval and Limits Are Determined

Lenders assess your trading history, revenue patterns, and existing debt when setting your credit limit. Most unsecured facilities require at least 12 months of trading history and consistent monthly revenue above $30,000, though these thresholds vary between lenders.

Your approved limit typically ranges from one to three months of average monthly revenue, depending on the strength of your financials and whether the facility is secured or unsecured. A business generating $400,000 in monthly revenue with steady receivables might secure a $600,000 facility, while a business with more variable income might be offered $200,000.

Secured lines of credit, where you provide assets as security, usually offer higher limits and lower interest rates than unsecured options. An asset finance broker can structure a facility secured against equipment, vehicles, or other business assets if you need larger amounts or more favourable terms.

Alternative Cashflow Solutions Worth Comparing

Debtor finance and invoice financing address cashflow gaps by advancing you funds against outstanding invoices before your customers pay. If you issue invoices with extended payment terms, this converts those receivables into immediate working capital. The advance rate is typically 80-90% of the invoice value, with the remainder paid when your customer settles.

This option suits businesses with strong receivables but limited tangible assets to secure traditional credit facilities. The funding grows with your sales, so as revenue increases, your available funds increase proportionally without needing to reapply or renegotiate limits.

Stock financing and inventory financing work similarly but advance funds against the value of your inventory rather than invoices. Importers and wholesalers often use this to purchase large shipments without depleting working capital, repaying the facility as they sell the stock.

The right cashflow solution depends on what's driving your funding gap. If your challenge is timing between expenses and revenue, a line of credit offers flexibility. If the issue is specifically slow-paying customers, debtor finance addresses the root cause directly. Many businesses use multiple facilities, drawing from whichever source makes sense for each situation.

What This Type of Funding Costs You

Interest rates on unsecured business lines of credit currently sit between 8% and 18% annually, calculated daily on your outstanding balance. The rate you're offered depends on your trading history, revenue consistency, and the size of the facility relative to your turnover.

Most facilities also include a monthly line fee, typically between $50 and $200, regardless of whether you draw any funds. This covers the cost of keeping the facility available. Some lenders charge establishment fees upfront, while others waive these costs if you maintain the facility for a minimum term.

The daily interest calculation means you pay for exactly the period you use the funds. If you draw $50,000 for 18 days at 12% annual interest, you pay approximately $295 in interest for that period. Repay the balance and you stop accruing interest immediately, unlike a term loan where interest accrues on the full amount regardless of whether you need it.

How to Access and Manage the Facility

Once approved, most lenders provide online access where you can transfer funds to your business account within hours. Some offer linked accounts where the line of credit automatically covers any shortfall in your operating account, functioning like a true overdraft.

Managing the facility effectively means drawing only what you need when a specific expense or opportunity arises, then repaying as revenue allows. The businesses that benefit most treat it as a buffer for genuine cashflow mismatches, not as permanent working capital.

Tracking your draws and repayments monthly helps you identify patterns. If you're consistently using 80% or more of your limit, you might need either a larger facility or a different funding structure. If you rarely draw more than 20%, you may be paying line fees for capacity you don't require.
