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

Potentially, but through agency law rather than the FDCPA. Federal telecom regulators have said a seller may be held vicariously liable under common-law agency principles for calls placed on its behalf, and 23 states extend their own collection statutes to original creditors as well as third-party agencies. The practical answer is to ask how an agency contacts debtors and to verify its licensing before placing accounts.

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.

Commercial collection is normally contingency-based - a share of what is actually recovered, commonly 10-40%. Account age drives the rate more than balance size: fresh accounts under 90 days commonly run 10-25%, 90-180 days 15-30%, 180 days to a year 20-35%, and over a year 25-40%. Some agencies also offer fixed-fee early-stage demands at roughly 15-20 dollars per account.

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.

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.
