(without sounding rude)

Late payments hurt cash flow, planning and your ability to take on new work. This guide gives a calm, professional chasing process that works for UK service businesses.

Late payment is common — especially for smaller firms

Multiple UK surveys report late payments as a widespread issue. Some research reports average delays measured in weeks and highlights that micro and small firms are often the most exposed.

The key isn’t “angry chasing”. The key is a professional process: clear invoices, clear terms, predictable reminders, and proof of delivery.

Before you chase: prevent late payment with 5 invoice basics

Due date: an actual date, not “ASAP”.
Payment instructions: bank details + reference (invoice number).
Clear scope: what was done, when, where.
Correct totals: subtotal, VAT (if applicable), total due.
Send as PDF + keep proof: email thread or share link.

A simple UK chasing timeline (copy/paste friendly)

Day 0: send invoice with due date + payment instructions.
Day 3–5: friendly reminder: “Just checking it landed safely.”
On due date: “Invoice due today — please confirm payment date.”
7 days late: firmer message: “Please confirm payment by [date].”
14+ days late: final notice: “If not paid by [date], we will pause further work / escalate.”

Keep it calm. Don’t accuse. Ask for a specific payment date.

Use deposits and stages (without scaring clients)

For material-heavy or multi-day jobs, deposits and stage payments reduce risk and keep both sides aligned. The trick is to write it simply: “Deposit to secure booking” and “Stage payment after milestones”.

If the client says: “I didn’t get it”

Resend as PDF and reply in the same email thread.
Include invoice number, date and total in the email subject line.
If possible, share a secure link that confirms access.
