Getting overdue invoices paid with a written system
The older an invoice gets, the harder it usually is to collect, so what you do in the first weeks matters most. Businesses that collect reliably tend to share one habit: a written escalation sequence that starts the day an invoice goes overdue and keeps going on schedule. It replaces angry emails and awkward phone calls with a set of steps the customer can see coming. When customers are juggling bills, they tend to pay first where there is a clear next step and a cost to waiting.
- The letters run on a set schedule: a reminder on day 1, a letter on day 10, a firm notice with interest running on day 30, a final demand on day 45 and a referral notice on day 60. Each letter refers to the one before, so the customer always knows what happens next, and that is where the pressure comes from.
- Paperwork heads off many problems before they start. A credit application (with a personal guarantee for customers that are companies) gets you a signed answer to “who am I really dealing with?” before you extend credit. Payment terms with late interest and costs-of-collection clauses put the cost of slow payment on the customer instead of on you.
- If the letters fail, the last step is a matter of numbers. Agencies typically keep 25–50%. Collection attorneys write demand letters for modest flat fees and take strong cases on contingency. Small claims handles invoices under your state’s limit for roughly $50–$150 in costs. Trades have lien rights with strict deadlines. The playbook sets out what each path costs so you can compare them side by side.
Will firm collections cost me clients?
A set sequence is easier on both sides than personal nagging, because it reads as your standard process rather than a confrontation. And a customer who pays only when no one asks is costing you money either way. The pack keeps a firm, professional tone until the final stage, so the relationship can survive once the money arrives.
Where the legal lines are
Collecting your own business receivables is not consumer debt collection (the FDCPA governs third-party consumer collectors), but state laws still limit interest rates and fees. The pack’s terms use “or the maximum permitted by law” wording and flag where to check. If you are collecting from an individual consumer rather than a business, take extra care; the playbook points out where the lines are.
