What can I legally do about a non-paying customer?

With a non-paying customer, you can usually send demands, pause further work if your contract allows, use a collection agency or attorney, and sue. Avoid threats, false statements, public shaming online and keeping property you have no right to. Check your contract before stopping work or holding deposits.

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.
