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

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.

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.

It can, which is why how an agency communicates matters as much as its rate. Ask about contact frequency, tone, dispute handling, and whether early-stage work is done as reminders under your name before escalation. Many agencies offer a softer pre-collection product for exactly this reason.

Commercial legal placement commonly starts around a $2,500 balance - below that the cost stack usually consumes the recovery. Litigation also changes the economics: an attorney suit fee sits on top of the agency's contingency, and court costs are separate. Ask for the all-in cost at your typical balance before agreeing to litigation as an escalation.

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.
