When a Client Won't Pay: The Contractor's Escalation Playbook

The due date passes. Then a week. Your messages get read and not answered. Every contractor knows this silence, and most handle it badly in one of two directions: too soft for too long, which costs money, or too aggressive too early, which torches clients who had simply forgotten. The fix is an escalation ladder — a fixed sequence you follow every time, so emotion never sets the pace.

Days 1–7: the polite resend

Step one, days one to seven overdue: assume cock-up, not conspiracy. The majority of late payments are admin — the invoice went to spam, the property manager is on holiday, the client thought their partner paid it. Resend the invoice with one polite line: 'Just flagging that invoice #1042 for £2,400 was due on the 14th — copy attached in case the original went astray.' No accusation, no apology either.

Week 2: pick up the phone

Step two, week two: pick up the phone. Email is easy to ignore; a call is not. Ask one question and then stop talking: 'Is there any problem with the work?' This does two jobs at once — it surfaces a genuine dispute early, while you can still fix it cheaply, or it removes their last excuse. If they say the work's fine, get a payment date on the call and confirm it by text before you hang up: 'Thanks — confirming you'll settle #1042 by Friday the 26th.'

Weeks 3–4: the firm letter

Step three, weeks three to four: the firm letter. Not angry — procedural. New deadline of seven days, a note that statutory interest is now accruing (on business-to-business work in the UK that's 8% plus base rate, and you don't need a contract clause to claim it), and a plain statement of what happens next: 'If payment isn't received by [date], I'll begin formal recovery, which adds costs I'd rather neither of us paid.'

If the client raises a dispute

If they raise a defect at any stage, switch tracks — this is now a dispute, not a debt, and bullying a disputed invoice backfires in court. Inspect quickly, fix what's fair, and get one thing in writing before you lift a tool: that the remaining balance is due on completion of the fix. The classic trap is fixing the snag and then discovering a new one materialises every time payment comes due.

The letter before action

Step four: the letter before action. In the UK courts expect one before you file, and it's often the step that gets you paid — something about the phrase concentrates minds. Keep it to half a page: the debt, the history of requests, a final deadline of 7–14 days, and confirmation that you'll issue a claim after that. Send it by email and post.

Small claims court

Step five: small claims. In England and Wales, Money Claim Online handles debts up to £10,000 with no solicitor and a modest filing fee that gets added to the claim. In the US, small claims limits run roughly $2,500 to $25,000 depending on the state. Here's the thing contractors don't believe until they do it: a large share of defendants pay as soon as the papers arrive. Court is rarely about the hearing.

When to write it off

Know when to fold. A £300 debt against ten hours of chasing and a filing fee is a bad trade — sometimes the professional move is to write it off consciously, blacklist the client, and price the lesson into your deposit policy. What you shouldn't do is let the write-off happen by default, through months of drift.

Prevention beats every step above

And prevention outranks every step above: a deposit before you start, stage payments on anything long, and automatic chasing at 7, 14 and 30 days so no invoice ever sits in silence. Serial late payers are good at picking targets — they choose contractors who look like they won't follow up. Look like one who will.
