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

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 depends on the state - 31 jurisdictions require a licence or registration, Texas requires only a $10,000 bond filed with the Secretary of State, and the rest require neither. The rule that surprises creditors is that several states look at where the debtor is located, so a multi-state ledger can require an agency licensed in states you never thought about.

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.

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.

Sometimes - it depends on your contract and state law. Where your terms and conditions provide for collection costs and interest, and the applicable state permits it, those amounts may be added to the claim. That clause is worth having in your standard terms before you need it; ask your counsel to review it.
