What to Do When a Client Won't Pay Your Invoice

📅 June 2026⏱ 5 min read✍️ Toolzilla Team

Late payments are a freelancer rite of passage. A structured escalation — friendly reminder, firm follow-up, formal demand — resolves most cases without lawyers.

Friendly Reminder (Day 1–7)

Email referencing the invoice number, due date, and original PDF attachment. Assume good faith — busy clients forget.

Firm Follow-Up (Day 14+)

Reference your contract's payment terms and late-fee clause. Stop work on any new phases until outstanding invoices are settled.

Formal Demand Letter

A demand letter is a written notice requesting payment by a specific date before further action. It carries more weight than an email and creates a paper trail.
