A customer who always paid in 30 days now pays in 50. That’s information, and you have roughly a quarter to use it.
Most owners spend that quarter making phone calls. Phone calls aren’t leverage.
→ Your credit application can carry a personal guaranty from the principal. That changes who your customer pays first when cash is short.
→ If you ship goods, a properly filed purchase-money security interest can put you ahead of their bank — but the filing and notice have to be done before delivery.
→ Under the UCC, reasonable grounds for insecurity let you demand adequate assurance in writing and suspend performance. No response within 30 days is treated as repudiation.
→ Payments a customer makes in the 90 days before a bankruptcy can be clawed back as preferences.
That last one runs against instinct. Aggressively changing terms with a struggling customer can strip the ordinary-course defense that would have protected the payments you collected. Sometimes the supplier who keeps shipping ends up better protected than the one who cut the customer off.
And read it from the other chair too. If you’re the one stretching payables, that’s a breach your vendor is tolerating — and it may be tripping a cross-default in your own credit agreement.
Slow pay is the first symptom, and it is information before it is a problem.
