Customer Not Paying Your Invoice? What to Do as a Tradesman

Your invoice is overdue. The customer has gone quiet. You are not sure whether to chase, wait, or assume the worst.

This happens to almost every tradesman. Here is exactly what to do - from your first reminder to your legal options - without damaging the relationship or letting the money disappear.

Why customers do not pay on time

Before assuming the worst, it helps to know what you are actually dealing with. Most late payments fall into one of four categories:

• Forgotten. The customer is busy, your invoice went to spam, or they simply have not got around to it. This is the most common reason, especially for one-off jobs.
• Cash flow. They are waiting for their own payment before they can pay you. They intend to pay - eventually.
• Unhappy with the work. There is a concern about the job they have not raised with you directly. The non-payment is a way of flagging it without having the conversation.
• No intention of paying. Rare, but it happens. Usually apparent early - multiple excuses, no replies, actively avoiding contact.

Your first reminder tells you a lot. How quickly they respond and what they say usually reveals which category you are dealing with.

Step 1 - Send a friendly reminder on the due date

On or shortly after the due date, send a polite written reminder. Assume it is an oversight. Most of the time, it is.

Hi [Name], just a quick note - invoice [number] for [amount] was due on [date]. Let me know if you need me to resend it or if you need the bank details. Thanks, [your name]

Send this by WhatsApp or email - not a phone call. Written reminders are easier for the customer to respond to in their own time, and they create a paper trail that protects you if the situation escalates.

Step 2 - A firm follow-up at 7 days overdue

If there is no response or payment after 7 days, send a second message. The tone stays professional but it is now direct.

Hi [Name], following up on invoice [number] for [amount], now 7 days overdue. Could you let me know when this will be paid? Thanks, [your name]

A direct question - "when will this be paid?" - requires a direct response. It is harder to ignore than a statement.

Step 3 - Final notice at 14 days overdue

If you are still being ignored after two reminders, the tone shifts.

[Name], invoice [number] for [amount] is now 14 days overdue. I have not received a response to my previous reminders. Please make payment by [date] or contact me to discuss. If I do not hear from you by then, I will look at the options available to me.

"The options available to me" is intentionally vague. It signals escalation without committing to a specific action. At this point you are within your legal rights to charge statutory interest and compensation in both Ireland and the UK.

Your legal rights if a customer refuses to pay

Most late payment situations resolve at step 1 or 2. But if a customer genuinely refuses to pay, you have legal rights in both countries.

In Ireland

Under the European Communities (Late Payment in Commercial Transactions) Regulations 2012, you can claim:

• Statutory interest at 8% per year above the ECB reference rate on the overdue amount
• Fixed compensation of between €40 and €100 per invoice depending on the amount owed
• Reasonable debt recovery costs on top of the above

Most sole traders never use these rights - but knowing you have them changes how you communicate in your final notice. See the full detail in our late payment rights guide for Ireland.

In the UK

Under the Late Payment of Commercial Debts (Interest) Act 1998, you can claim:

• Statutory interest at 8% above the Bank of England base rate
• Fixed compensation: £40 for invoices under £1,000, £70 for £1,000 to £9,999, £100 for £10,000 and above
• Reasonable debt recovery costs beyond those fixed amounts

See the full breakdown in our late payment rights guide for the UK.

What if they dispute the invoice?

If a customer comes back with a concern after receiving a reminder, do not react immediately. Ask them to put their concern in writing. This creates a record and often reveals whether the concern is genuine or a tactic to delay payment.

If there is a genuine issue with the work, try to resolve it. If the dispute is unreasonable, respond calmly and in writing, and stick to your position.

When to involve a solicitor or small claims court

If the final notice gets no response and no payment, you have a few escalation options:

• Small claims court. In Ireland, the Small Claims Procedure covers debts up to €2,000. In the UK, the Small Claims Track covers debts up to £10,000. Both are designed to be used without a solicitor and are low cost relative to the amount recovered.
• A solicitor's letter. A formal letter from a solicitor or debt recovery agency sometimes prompts payment where your own reminders did not. The cost is usually modest and can be added to the debt being claimed.
• Debt recovery agency. They take a percentage of the recovered amount but do the chasing work for you. Worth considering for larger amounts where you cannot afford the time.

How to stop this happening on the next job

Late payment is easier to prevent than to fix. A few habits make a real difference:

• Set clear payment terms before you start. Put your payment terms on the quote - not in the small print but at the top, where the customer has to read them before accepting.
• Invoice immediately on completion. Send it the same day the job is done. The longer you wait to invoice, the longer you wait to be paid.
• Take a deposit on bigger jobs. A 30-50% deposit upfront means you are never chasing the full amount. It also filters out customers who were never serious about proceeding.
• Send a reminder before the due date. A heads-up 2 days before catches the forgotten-invoice cases before they become overdue ones.
