Most clinic operators encounter a business line of credit in one of two circumstances: their accountant recommends setting one up before they need it, or they're in a cash flow squeeze and need one now. The operators who set it up before they need it tend to have better outcomes. Here's why the distinction matters — and how the product actually works.
What a Line of Credit Is and Isn't
A business line of credit is a revolving credit facility — a maximum borrowing limit against which the business can draw funds as needed, repay, and draw again. Unlike a term loan, which provides a fixed lump sum repaid over a scheduled term, a line of credit provides flexible access to capital up to the approved limit. Published commercial banking resources describe lines of credit as a working capital tool, not a capital investment tool — designed for managing timing differences between cash inflows and outflows, not for funding long-term assets.
The key mechanics: interest accrues only on the outstanding balance, not on the full limit. A $50,000 line with $15,000 drawn costs interest on $15,000. When the balance is repaid, interest stops. The limit remains available to draw again. Published banking resources describe this as making a line of credit significantly cheaper than a term loan for short-term working capital needs — because the effective borrowing period is much shorter than the facility term.
How Lines of Credit Are Used in Clinic Operations
Published practice management resources describe several common uses for a clinic line of credit:
Managing the billing lag. For practices with insurance billing — US physical therapy, chiropractic, dental — there is typically a 30–90 day gap between service delivery and payment receipt. A line of credit allows the practice to meet payroll and rent obligations while waiting for insurance payments to clear, rather than building a permanent cash buffer large enough to cover the lag. Published resources describe this as particularly relevant for new practices where the billing volume is growing rapidly and the lag creates a cash flow gap even when the underlying revenue is strong.
Seasonal smoothing. Published practice management resources note that many clinic types show seasonal revenue variation — physiotherapy practices may see higher volume in January (post-holiday motivation) and lower volume in July (vacations). A line of credit smooths the cash flow through lower-revenue periods without requiring the practice to hold excess cash during higher-revenue periods.
Opportunity investment. Equipment upgrades, marketing initiatives, or lease improvements that have a clear payback period but require upfront capital may be funded from a line of credit and repaid as the return materialises. Published resources distinguish this from long-term capital investment — a line of credit should not be used to fund assets with multi-year payback periods.
How Lines of Credit Are Structured and Priced
Published Canadian banking resources describe business lines of credit as typically priced at prime rate plus a spread — with the spread reflecting the borrower's credit profile and the secured or unsecured nature of the facility. Published resources describe secured lines (backed by accounts receivable or other business assets) as typically carrying lower spreads than unsecured lines.
In the US, published commercial banking resources describe business lines of credit as similarly priced at prime rate or SOFR plus a spread. Published resources note that the availability and pricing of a business line of credit is closely tied to the business's financial history — which means a new clinic is unlikely to qualify for a meaningful line immediately, but an established practice with two or more years of clean financial statements and positive operating cash flow typically can.
When to Set One Up
Published banking and accounting resources consistently describe the optimal time to establish a business line of credit as when it isn't needed — specifically, when the business has strong financials and doesn't require the facility to operate. Applying for credit from a position of strength produces better terms and higher probability of approval than applying from a cash flow squeeze, when the bank's assessment of risk is higher and the borrower's negotiating position is weaker.
