Most owners describe their line of credit as a number. It isn’t. It’s a ceiling over a floor that moves every month.
If your line advances against accounts receivable, here’s the mechanic that catches profitable companies:
→ Your eligible receivables are the good ones — current, undisputed, from customers who pay. → Those are also the ones that collect first.
→ A $100,000 eligible receivable pays, and $80,000 of borrowing capacity goes with it. → If commissions, subs and sales tax come out of that collection, less than $100,000 reaches the lender.
→ Base drops $80,000. Loan drops $70,000. You just lost availability by collecting.
Do that for a quarter and what’s left in the aging is the slow material. The base erodes while the balance sits still, and the loan agreement says you cure the over-advance in cash.
Then the shell game starts: invoicing early, asking a customer to pay ahead so the month-end certificate reads right, re-dating an aged invoice. Each move buys a week and makes the next week worse — and that certificate is a signed representation to your lender, not a report.
Profit and availability are not the same thing. Your line runs on the second one.
