Using a Line of Credit to Bridge AR Gaps
Module 4: Cash Flow & Working Capital, Chapter 5
The short answer
A business line of credit is a flexible financing tool that lets you draw cash to cover the gap between when expenses are due and when AR actually converts to cash, then repay it as invoices are collected. It's a legitimate bridge, not a fix for the underlying DSO problem, and it costs real interest on whatever's drawn.
How does a line of credit actually work for this purpose?
Unlike a term loan, a line of credit lets you draw only what you need, when you need it, and pay interest only on the drawn amount, not the full available limit. For a business with a predictable AR-driven cash gap, this makes it a natural bridge tool: draw to cover payroll or vendor payments during a slow collection stretch, then repay as invoices clear.
When does this actually make sense to use?
- A temporary, predictable gap, seasonal slowness, a large client's known slow-pay pattern, not a chronic, worsening DSO problem.
- When the cost of the credit line is genuinely less than the cost of the alternative, missing payroll, damaging a vendor relationship, or turning down new work due to cash constraints.
When is it the wrong tool?
When it's being used to paper over a genuinely broken collections process rather than bridge a real, temporary gap. A line of credit that's permanently drawn to its limit isn't bridging anything, it's quietly substituting for the harder work covered in Modules 1-3: better credit terms, consistent follow-up, and a real aging report review. Fixing the underlying DSO problem is almost always cheaper than financing around it indefinitely.
What does it actually cost?
Typically a variable interest rate on whatever's drawn, plus sometimes a smaller fee on the unused portion of the line. The exact cost depends heavily on your business's credit profile and the lender, but treating it as free capital is a mistake, every dollar drawn to bridge an AR gap is a dollar that could instead be freed up by collecting faster in the first place.
How does this connect to everything else in this course?
A line of credit buys time. It doesn't replace the actual work of Module 1's aging discipline, Module 2's clean invoicing, or Module 3's credit and collections process. The businesses that use credit lines most effectively tend to be the ones that also have the strongest underlying AR practices, using the bridge for genuine timing gaps, not as a permanent crutch for a process that was never fixed.

Frequently asked questions
Is a line of credit hard for a small business to qualify for?
It depends on your business's credit history and financials, generally easier to obtain with at least a couple of years of operating history and consistent revenue, but options exist for newer businesses too, often at a higher cost.
Should a line of credit replace holding a cash reserve?
It's better thought of as a complement, not a replacement. A cash reserve costs nothing to hold; a credit line costs interest whenever it's actually drawn.
What comes after this chapter?
The module's final chapter pulls everything together into a practical 13-week cash flow forecast, the tool that actually tells you whether and when you'd need to draw on a line like this.
