Frequently asked questions
How do I politely follow up on an unpaid invoice?
Start with a friendly reminder assuming the oversight was accidental (tone: Friendly). If no response after 7 days, send a professional follow-up referencing your original email. After 14 days, escalate to a firm notice. Use the Final Notice tone when the invoice is 30+ days overdue and you are prepared to escalate further.
Can I legally charge a late fee on overdue invoices?
Generally yes, as long as the late fee policy was disclosed upfront in your contract or on the original invoice. The standard late fee is 1–2% per month (12–24% annually). Always state your late payment terms on every invoice you send.
What should I do if a client still doesn't pay after multiple reminders?
After 3–4 follow-ups with no response or resolution, consider sending a formal letter of demand, contacting a collections agency, filing a small claims court case (most jurisdictions handle disputes up to $5,000–$10,000), or consulting a lawyer for larger amounts.
