What to do if a customer refuses to pay an invoice (Ireland)

If a customer refuses to pay an invoice, start by confirming the contract, sending a clear written demand and offering a short opportunity to resolve the dispute; if that fails, weigh small-claims court (where appropriate), formal civil proceedings, or targeted legal advice depending on the amount and complexity. Acting promptly, documenting every contact, and choosing a proportionate next step will usually produce a better outcome than an immediate, costly litigation push.

The short answer above sets out the sensible path. Below I explain how to assess the situation, prepare a useful written demand (what lawyers call a "letter before action"), and choose between negotiation, the Small Claims process, or a civil claim in the District Court — all explained with the practical constraints that matter for Irish suppliers.

Check the basics first: contract, delivery and evidence

Before you demand payment, be sure the debt is actually owed. Re-read the contract, invoice terms and any delivery or acceptance records. Important items to locate and note:

• The invoice and the due date shown on it. Quote those exact figures in any demand.
• Your contract, purchase order or written terms that set price, scope and payment terms.
• Delivery or completion evidence (signed delivery notes, email confirmations, timesheets, or photographs).
• Any previous correspondence where the customer acknowledged the debt or raised a specific dispute.

If the customer is disputing quality or scope, that changes the next steps: you must address the underlying dispute (offer inspection, repair, proof of compliance) rather than treating the case as a straightforward unpaid bill.

Send a clear written demand and keep records

A concise, firm written demand is the most useful early tool. It does three things: it documents your position, gives the debtor a final opportunity to pay, and creates a clear paper trail should you later go to court.

What to include in the demand:

• A precise statement of the amount owed, the invoice number and the due date.
• A short, firm deadline for payment (for example, 7–14 days is common in practice — treat this as a practical choice, not a universal legal requirement).
• A brief summary of why you believe the invoice is payable (goods delivered, services completed, relevant contract clause).
• A clear statement of the next step if payment is not received (mediation offer, small-claims application, or court proceedings).
• How the debtor can pay (bank details, online payment link) and who to contact to discuss a payment plan.

Record how you send the demand (email, registered post, courier) and keep copies of delivery receipts. A well-documented demand often produces payment — it also makes any later claim clearer.

Offer settlement or mediation where sensible

If cashflow matters to either side, propose a short payment plan or mediation. The Department of Enterprise highlights mediation and consumer/alternative dispute routes as sensible, lower-cost ways to resolve many money disputes before formal legal steps. See the government's practical overview of consumer dispute routes for more context and links to relevant services: Department of Enterprise — Useful Links for consumer rights and dispute routes.

Offering a reasonable instalment plan or a structured settlement can recover more money faster than a headline-grabbing legal threat. Be sure to get any agreement in writing and update your invoice records.

Consider small claims if the amount fits and the case is simple

For lower-value disputes the Small Claims route is usually quicker and cheaper than instructing solicitors. The Department of Enterprise lists the Small Claims Court as a cost-effective remedy for disputes under a specified monetary threshold — a practical route frequently used by consumers and small businesses. Check the precise current monetary limit and the eligibility rules for your case before proceeding (the department’s page is a helpful starting point: Department of Enterprise — Useful Links).

Small Claims is best for straightforward sums where liability is not seriously disputed and the costs of solicitors would exceed likely recovery. If the other party raises factual or legal disputes, or the amount exceeds the small-claims threshold, a District Court claim or solicitor involvement may be necessary.

When to start court proceedings and what to expect

If negotiations and small-claims attempts fail, a civil claim in the appropriate court may be needed. Procedural rules — how to start a claim, fees, representation and timing — vary by court. A practical litigation overview emphasises that rules on representation and case management differ across forums in Ireland and that businesses should confirm whether they must use a solicitor for particular courts or claims: see the DLA Piper procedural guide for an accessible discussion of these civil procedure considerations: DLA Piper — Procedural steps and timing (Ireland section).

Two practical cautions before filing:

• Check time limits. Contract and debt claims are subject to limitation periods. Do not assume a particular period applies; verify the correct statutory deadline relevant to your type of contract before you delay.
• Factor in costs. Litigation can be slow and expensive. For modest sums, the net recovery after fees may be small — that is why many creditors prefer settlement or small claims where eligible.

A realistic worked example

Imagine you’re a sole trader who supplied €1,200 of services and the invoice is 60 days overdue. You have delivery emails and a signed acceptance form. Action that fits the situation:

1. Send a written demand (quote the invoice number, attach evidence, give 10 days to pay).
2. If the customer replies with a cashflow problem, offer a two-month instalment plan in writing.
3. If the customer ignores the demand, consider the Small Claims route (if the monetary threshold applies) or a District Court claim if small claims are unsuitable.

Practical records — the invoice, delivery confirmation, and the written demand — will be the core of your case in any forum.

When to get legal advice or use a document service

If the amount is large, the customer disputes the facts, or the case turns complex (multiple invoices, cross-border elements, or alleged defects), consult a solicitor to avoid procedural mistakes. For straightforward claims where you simply need a professionally drafted demand letter, a document service that prepares a clear, legally informed demand from your materials can be a proportionate option: .

A professionally prepared demand does not guarantee payment, and it is not the same as legal representation, but it can sharpen your case and make escalation clearer to the debtor.

Decide with proportion in mind: a measured demand and a willingness to negotiate will recover the majority of small debts; formal court action is a tool for when reasonable resolution fails.
