What it means for your business

Tone matters less than timing and specifics

The emails that work name the invoice number, the amount, the original due date and a new one. They assume good faith and make paying the path of least resistance.

What you can do this week

Use this three-message sequence

Spaced a few days apart, escalating in firmness but never in rudeness. Keep copies - you'll rarely need them, but it helps if you do.

  • Day 1 overdue: a one-line friendly nudge with the invoice attached
  • Day 7: a firmer note with a clear new payment date
  • Day 14: mention your right to statutory interest, calmly
8%+

Statutory interest you can charge on overdue commercial invoices (base rate + 8%)

Common questions
