How to Chase Unpaid Invoices Without Losing Customers

24 February 2026

Late payment is one of the most frustrating parts of running a trade business. You have done the work, the customer is happy with it, but the money does not arrive. Chasing payment feels awkward, especially when the customer is someone you want to work for again. The good news is that with the right approach, you can follow up firmly without damaging the relationship.

Prevention Is Better Than Chasing

The best way to deal with unpaid invoices is to avoid them in the first place. Most late payments are not malicious — they happen because payment was inconvenient, the terms were unclear, or the customer simply forgot. Here is how to reduce the chances:

Agree payment terms upfront. Before starting any job, make sure the customer knows when payment is due. Put it in writing on your quote. "Payment due within 14 days of invoice" is clear and reasonable.
Take a deposit. A deposit of 30-50% before work begins reduces the amount at risk and establishes that payment is expected, not optional.
Make paying easy. Offer bank transfer, online payment, or card payment. The more options you give, the fewer excuses there are. If the customer has to write a cheque and post it, you are adding friction.
Invoice immediately. Send the invoice on the day the work is completed, or at the latest the following morning. The longer you wait to invoice, the longer you wait to get paid. The job is fresh in the customer's mind on completion day — use that.

The Follow-Up Timeline

When payment does not arrive on time, follow up consistently and professionally. Here is a timeline that works well:

Day 1 (due date): If payment has not arrived by the due date, send a brief, friendly reminder. This should feel like a nudge, not a demand. Something like: "Hi [Name], just a quick reminder that invoice #1234 for €1,500 was due today. You can pay online at [link] or by bank transfer to [details]. Let me know if you have any questions."

Day 7: If there has been no response, follow up again. This time, pick up the phone. A call is harder to ignore than an email, and it gives the customer a chance to explain if there is a genuine issue. Keep it light: "Just following up on invoice #1234 — wanted to make sure you received it and check if there are any issues."

Day 14: Send a firmer written reminder. At this point, the payment is two weeks overdue and the tone should reflect that. State the amount, the original due date, and ask for payment within seven days. Mention that you may need to pause any ongoing or future work until the account is settled.

Day 30: Send a formal letter or email stating that the invoice is now 30 days overdue. Reference your payment terms and note that continued non-payment may result in further action. This is still professional, but it makes clear you are serious.

Day 45+: At this point you have sent multiple reminders and made phone calls. If the customer is still not paying and not communicating, you need to consider escalation. Options include a solicitor's letter, a debt collection agency, or the Small Claims Court.

How to Word the Reminders

The language you use matters. You want to be firm without being aggressive. Here are some phrases that work well, and some to avoid:

Good phrases:

"Just a friendly reminder that invoice #1234 is now overdue."
"Could you let me know when I can expect payment?"
"I'd appreciate if this could be settled by [date]."
"If there's an issue with the invoice, I'm happy to discuss it."
"I understand things get busy — just wanted to make sure this hasn't slipped through the cracks."

Phrases to avoid:

"You owe me money." (Confrontational and puts people on the defensive.)
"If I don't receive payment I'll take legal action." (Too aggressive for early reminders. Save this for the 30+ day mark if genuinely needed.)
"I can't believe you haven't paid yet." (Emotional and unhelpful.)

If you're using Workcanon, you can set up automatic invoice reminders that send at intervals you choose. This takes the awkwardness out of chasing — the system sends professional reminders on your behalf, and you only need to get personally involved if the customer does not respond.

What If They Dispute the Invoice?

Sometimes a customer will not pay because they are unhappy with the work, or they believe the amount is wrong. This is different from simply ignoring your invoice, and it needs a different approach.

First, listen. Ask them to explain exactly what the issue is. If there is a genuine problem with the work, offer to fix it. If the dispute is about price, refer back to the original quote and what was agreed. Having a clear, detailed quote makes these conversations much easier — it is hard for someone to dispute a price they agreed to in writing.

If you cannot resolve the dispute between you, suggest mediation. This is cheaper and less stressful than going to court, and it shows you are acting in good faith.

If a customer disputes a small part of the invoice, ask them to pay the undisputed portion while you resolve the rest. This keeps some cash flowing and demonstrates willingness to work things out.

When to Escalate

If multiple reminders and phone calls have not worked, and the customer is either ignoring you or making excuses without paying, you have several options:

Solicitor's letter. A formal letter from a solicitor often prompts immediate payment. The cost is usually €100-200, and the psychological impact is significant.
Small Claims Court. In Ireland, you can use the Small Claims Court for debts up to €2,000. It costs just €25 to file a claim, and the process is designed to be used without a solicitor. Claims are filed online through the Courts Service website. For amounts above €2,000, you would need to go through the District Court or Circuit Court, which involves higher costs and more complexity.
Debt collection agency. An agency will chase the debt on your behalf, typically taking a percentage of the amount recovered. This can be effective but costs you a portion of what you are owed.

When It's Not Worth Chasing

Sometimes you need to cut your losses. If the amount is small (under €100-200), the customer has disappeared, or the cost of chasing exceeds the debt, it may not be worth pursuing. Write it off, learn from it, and tighten your processes for next time — take a deposit, set clear terms, and invoice promptly.

Keep a record of bad debts for your accountant, as they may be deductible against your tax liability.
