How I built a free invoice chasing system (no SaaS needed)

Most freelancers handle late invoices one of two ways:

  1. Ignore it and hope the client pays eventually
  2. Send a passive-aggressive email that damages the relationship

Both are terrible. Here's a better system.

The 4-stage escalation framework

I built this based on UK late payment law and what actually works:

Stage 1: Friendly reminder (1-7 days overdue)

Hi [name], just a quick one — invoice #X for £Y was due on [date]. Could you confirm when payment will be processed? Happy to resend if needed.

Key: assume it's an oversight. No accusations.

Stage 2: Firm follow-up (8-14 days)

Hi [name], following up on invoice #X (£Y), now [X] days overdue. Could you let me know a specific date I can expect payment? I've attached the original invoice for reference.

Key: ask for a specific date, not just "when you can".

Stage 3: Formal notice (15-21 days)

Now you mention the law:

Under the Late Payment of Commercial Debts (Interest) Act 1998, I'm entitled to charge statutory interest of 8% + Bank of England base rate on overdue invoices, plus a fixed compensation amount.

Key: this isn't a threat, it's a statement of fact. Most clients pay at this stage.

Stage 4: Letter Before Action (22+ days)

Final demand. 14 days to pay or you file in small claims court.

For amounts under £10,000, UK small claims court costs £35-£455 and you don't need a solicitor.

Free tools I built for this

Instead of writing each email from scratch:

Prevention is better than chasing

The best invoice system is one where you rarely need to chase:

  1. Clear payment terms in your contract (not just "30 days" — spell out the consequences)
  2. Invoice immediately when work is delivered
  3. Deposit upfront — 30-50% before starting
  4. Milestone payments for larger projects
  5. Auto-reminders set up before the due date, not after

The numbers that matter

In the UK:

  • Average freelancer is owed £5,851 in late payments at any time (IPSE/Crunch survey)
  • 29% of invoices are paid late
  • Average delay: 14.5 days past due date
  • Only 12% of freelancers charge late payment interest (even though it's their legal right)

Don't be in the 88% that leaves money on the table.
