How do the UCC and unpaid invoices relate?
The UCC and unpaid invoices connect when you sell goods: the Uniform Commercial Code, adopted with changes by states, sets rules for sales contracts, buyer and seller remedies, and a four-year limitation period from accrual that parties can shorten to one year. Services contracts generally fall under general contract law instead.
What do the UCC and unpaid invoices cover?
Sales of goods, delivery, acceptance and remedies[source].
Does the UCC cover services?
Generally no; contract law applies.
General information, not legal advice. Laws vary by state and situation; ask a licensed attorney about yours.

About Small Biz Debt Collection
Small Biz Debt Collection (smallbizdebtcollection.com) is a free matching service that connects U.S. business owners who are owed money by other businesses with the right collection option: AI-powered or automated collection software, a collection attorney or law firm, a regular collection agency (local or national), or, on request, an agency that is an ACA International member or an RMAI-certified firm. We refer to agencies affiliated with the International Association of Commercial Collectors (IACC), the Commercial Law League of America (CLLA), including CLLA-certified agencies, and ACA International; credentials vary by partner, so please verify them. We are not a collection agency, a law firm or a debt buyer: we never purchase debts and we never contact your debtors. Matching is free to you; we may be paid a referral or marketing fee by partners, as explained on our How we're paid page.
