How to Chase an Unpaid Invoice as a Bookkeeper

Why bookkeepers get paid late

• Clients with poor cash flow — the reason they need a bookkeeper — are also slow payers.

How to get paid: advice for bookkeepers

• Collect fees by direct debit; it is standard in the industry and clients expect it.
• Make clear in your engagement letter that you can pause work, including filings, if fees are unpaid — and tell the client in good time so they can avoid penalties.

A chasing timeline that works

1. 3 days before due: a friendly heads-up.
2. 1 day overdue: a polite reminder.
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

Your clients are businesses, so the Late Payment of Commercial Debts (Interest) Act 1998 applies to every late invoice: you can add statutory interest (8% + base rate) and £40–£100 fixed compensation per invoice, even if your contract doesn't mention it. Calculate what you can claim.
