How to Chase an Unpaid Invoice as a Interior Designer

Why interior designers' clients pay late, what to send at each stage, and your options if they still don't pay.

Why interior designers get paid late

  • Clients query procurement costs once items arrive.
  • Long projects mean the final design fee is invoiced months after the work.

How to get paid: advice for interior designers

  • Never place orders on your account before the client has paid for them.
  • Invoice design stages as you complete them rather than all at the end.

A chasing timeline that works

  1. 3 days before due: a friendly heads-up.
  2. 1 day overdue: a polite reminder — a text often works well with private clients (write one).
  3. 7–14 days overdue: a firm reminder and a phone call.
  4. 30 days overdue: a final notice with a deadline.
  5. Still unpaid: a letter before action, then a small claim if needed.

Your legal options

It depends who the client is. For business clients, you can add statutory interest (8% + base rate) and £40–£100 fixed compensation under the Late Payment Act — calculate it here. For private clients, that Act doesn't apply: only charges in your agreed terms, if fair, can be added. Before court action against an individual (including a sole trader) you must give 30 days' notice under the Pre-Action Protocol for Debt Claims.
