Why these gaps
The spacing of 1, 7, 14 and 30 days is a common routine for small suppliers, not a legal rule: it keeps the first message friendly, gives the client time to answer, and leaves a written trail before you escalate. If your contract or the client's payment run says otherwise, follow that. Monday-to-Friday dates are the default because a reminder that lands in a client's inbox on Saturday is easy to miss.
What to send at each step
- Day 1 and day 7. Use the wording in the payment reminder email templates.
- Day 14. Pick up the phone, and write down the date the client promises to pay. A promise gives you something specific to hold the next message to.
- Day 30. For a UK business-to-business debt you can add statutory interest and a fixed recovery sum; work them out with the late payment interest calculator.
- After the final notice. The letter before action generator writes the last formal step before a court claim.
This is a planning aid, not legal advice. Read the full guide to chasing an unpaid invoice for the reasoning behind each step.
