The state rule, the city rule, and the one that follows your debtor

Statutes of limitation are state law and commonly run 3-6 years for commercial obligations, varying by whether the debt rests on a written contract, an open account or an oral agreement. In many states a partial payment or written acknowledgement can restart the clock - which is worth knowing before agreeing to a payment plan on a very old balance.

In some states, more than you would expect. Washington's statute bars an unlicensed agency from bringing or maintaining a collection action in that state's courts - so a licensing gap can make an otherwise collectable account unenforceable there. There is no nationwide rule making debts void, and this site does not claim one; check your state's page and verify licensing before placing.

No. The Fair Debt Collection Practices Act defines 'debt' as an obligation of a consumer arising out of a transaction primarily for personal, family or household purposes - business-to-business obligations fall outside the statute entirely. That does not mean B2B collection is unregulated: state collection statutes, phone-consent rules, contract terms and ordinary law still apply.

Sooner than most businesses do. Commercial accounts are commonly reported as around 68.9% collectable at three months past due and around 51.3% at six months, with recovery falling sharply after a year - and the commission rises over the same period. Waiting costs twice. A written escalation ladder with a fixed placement date recovers more than case-by-case judgement.

An agency works your account for a share of what it recovers and returns what it cannot collect - you keep ownership of the debt. A debt buyer purchases the account outright, usually for cents on the dollar, and keeps everything it recovers. For unpaid B2B invoices where the customer relationship may be salvageable, the agency model is normally what businesses want.
