Irish small businesses tend to get paid sooner when they agree a clear payment date up front, send correct invoices straight away, make paying as easy as tapping a link, and remind customers on a fixed schedule. Between businesses, you're also entitled to statutory interest and fixed compensation on late invoices without sending a reminder. ISME's survey of SME owners for Q1 2026 put the average wait for payment at 44 days.

The short version
- ISME's Q1 2026 survey put the average wait for payment at 44 days.
- Agree a payment date in writing and invoice on the day work finishes.
- Payment links and direct debit make paying quicker for your customers.
- Late business invoices carry interest at 10.4% a year from 1 July 2026.
- Small Claims cannot be used to recover unpaid invoices.
How long Irish businesses wait to be paid
ISME's Prompt Payments Report for Q1 2026, a survey of 80 SME owner-managers, found businesses waited 44 days on average to be paid, five days longer than the previous quarter. It's a small sample, so treat it as a sense of direction rather than a precise national figure.
The law sets a default for when you don't agree a date. Between businesses, if your contract doesn't say when payment is due, it's due 30 calendar days after the later of the customer receiving your invoice or you delivering the goods or service. The terms you set, how quickly you invoice and how you follow up all affect where your own customers land between that default and the 44-day average.
What slow payment ties up
Do the arithmetic for your own business, because days of credit turn directly into money you've earned but can't use.
Take a business that invoices €20,000 a month. If customers take 44 days on average to pay, roughly 44 days' worth of sales is unpaid at any one time, which comes to about €29,300 (€20,000 × 44 ÷ 30). If the same customers paid in 30 days, the amount outstanding would be about €20,000. The difference, around €9,300, is cash that's sitting with your customers instead of in your account for as long as the pattern holds.
That €9,300 is roughly what you'd otherwise need from an overdraft or your own pocket to cover wages and bills. Bringing the average down by a single week frees about €4,700 of it (€20,000 × 7 ÷ 30), without selling anything more. Run the same sum with your own monthly invoicing and the average number of days your customers take to pay.
Terms and invoices that get paid on time
Before any chasing starts, the terms you agree and the invoice you send set up when you're likely to be paid. If the customer never agreed a date, or the invoice is missing something their accounts team needs, it's likely to sit in a queue.
- Agree a payment date in writing before you start work, on your quote, engagement letter or terms. Between businesses, terms over 60 days have to be expressly agreed in the contract and can't be grossly unfair to you, under S.I. 580 of 2012.
- For larger jobs, ask for a deposit or stage payments. You're not waiting for the whole amount at the end, and the customer has committed before you've spent money on materials or time.
- Invoice on the day the work is done or the period ends. For VAT-registered businesses, Revenue requires a VAT invoice to issue within 15 days of the end of the month in which you supplied the goods or services, but there's no reason to wait that long.
- Get the details right first time. Revenue's list for a VAT invoice includes the date, a unique sequential number, your name, address and VAT number, the customer's name and address, a description of what you supplied, the VAT-exclusive price, the VAT rate breakdown, total VAT and the date of supply. Add the due date and how to pay.
- If you work for the public sector, public bodies operate a government policy of paying suppliers within 15 days of receiving a valid invoice. It's an administrative policy, not a law, and the Regulations themselves set a 60-day ceiling for public bodies, and the 15 days count from receipt of a valid invoice, so check each one is complete and correctly addressed.
On the VAT side, Revenue lets businesses with turnover that doesn't exceed, and isn't likely to exceed, €2,000,000 in any 12 months use the cash receipts basis, also called moneys received. Your accountant can tell you whether it suits your business.
Make paying the easiest option
Customers tend to pay sooner when paying takes a few seconds. An invoice that only lists bank details asks the customer to log in to their banking app, set up a payee and copy a reference, and every step is a chance to put it off.
A payment link on the invoice, or sent by email, SMS or WhatsApp, lets them pay by card, Apple Pay, Google Pay or bank transfer from whatever device they're holding. For customers you bill every month, a SEPA direct debit mandate means the money is collected on the due date without anyone having to act. Under the SEPA rules you give at least 14 calendar days' notice of each collection unless you agree otherwise, and that notice can go on the invoice itself.
Adfin lets your customers pay by SEPA direct debit, card, Apple Pay, Google Pay or bank transfer from links sent by email, SMS or WhatsApp. Its price is per successful payment, 20c + 1%, and for direct debit and bank transfer the 1% part never goes above €2, so a €900 invoice paid either of those ways costs €2.20 to collect. Cards aren't capped. You don't pay a monthly fee or a setup fee, and there's no contract.
A reminder schedule you can keep to
A reminder schedule only helps if it runs every time, including the weeks you're too busy to chase. Decide the schedule once and apply it to every invoice.
- A few days before the due date, send a friendly note with the amount, the date and the payment link. This can catch invoices that were never approved or were sent to the wrong person.
- On the due date, send a short reminder that the invoice is due today.
- A week after, send a firmer message and, for regular customers, a statement of everything they owe. A statement can surface a missing invoice or a query nobody raised.
- Two to three weeks after, pick up the phone or have the account owner get in touch directly, and agree a date.
- After that, decide whether to add late payment interest or escalate.
Use more than one channel where you can, because an email can sit unread for weeks, while a text or WhatsApp message with a link may be seen sooner. Give every overdue customer an owner in your team, with a note of the next step and when it's due, so nothing waits on someone remembering.
Adfin's Essential credit control is free under a fair use policy and covers unlimited reminders by email, SMS and WhatsApp, statements, Xero or QuickBooks sync and an aged debtors view where each debtor has an owner and next steps. On Enhanced, which costs 0.3% per paid invoice and only when used, Adfin's collection agents decide when each reminder goes out, through which channel and how firmly it's worded, all within rules you approve, and emails go out from your own address.
Late payment interest and compensation
If your customer is a business or a public body, the European Communities (Late Payment in Commercial Transactions) Regulations 2012 (S.I. 580 of 2012) give you two things when an invoice is paid late, without needing to send a reminder first. Interest runs from the day after the payment date at the ECB's main refinancing rate plus 8%, which is 10.4% a year from 1 July 2026; the rate is reset each 1 January and 1 July. You're also entitled to fixed compensation for recovery costs, plus reasonable further costs such as a solicitor or collection agency. These rights don't apply to consumers.
| Invoice amount | Interest for 30 days late at 10.4% | Fixed compensation |
|---|---|---|
| €800 | €6.84 | €40 |
| €1,500 | €12.82 | €70 |
| €4,500 | €38.47 | €70 |
| €15,000 | €128.22 | €100 |
The compensation bands are €40 for invoices up to €1,000, €70 for those over €1,000 and up to €10,000, and €100 above €10,000. On the three smaller invoices in the table, the fixed sum is more than 30 days' interest.
ISME's Q1 2026 survey found 82% of the SME owners surveyed don't charge interest on late payments, and 13% said they were afraid to in case they lost the customer. Whether to charge it is a commercial choice. You can state the rights on every invoice and apply them only after a grace period, or waive them for a good customer who slips once. On Enhanced credit control, Adfin can add statutory late payment interest to overdue invoices between businesses automatically, with grace periods and waivers for individual customers.
When reminders don't work
When an invoice is well overdue and the customer has stopped replying, the next step is usually a formal demand. Sending a 7-day demand letter before starting legal proceedings is the usual practice, though it isn't always a legal requirement.
If you go to court, the amount decides which one. The District Court hears claims up to €15,000, the Circuit Court up to €75,000 and the High Court above that. Debts such as unpaid invoices can't go through the Small Claims procedure, which covers claims up to €2,000. Before you start, weigh the amount owed against the cost and time involved, and get advice on the claim.
Common questions
How long do Irish businesses take to pay invoices? ISME's survey of SME owners for Q1 2026 found the average wait for payment was 44 days, five days longer than the quarter before. It surveyed 80 owner-managers, so it's an indication rather than a national measure.
What are standard payment terms in Ireland? There's no single standard, but if a business-to-business contract sets no date, payment is due 30 calendar days after the later of invoice receipt or delivery. Terms over 60 days between businesses must be expressly agreed and not grossly unfair to the supplier.
Can I charge interest on a late invoice in Ireland? You can, on invoices to businesses and public bodies, at the ECB main refinancing rate plus 8%, which is 10.4% a year from 1 July 2026 and is reset each January and July. Interest runs from the day after the payment date and you don't need to send a reminder first.
Can I use the Small Claims court for an unpaid invoice? Debts such as unpaid invoices are excluded from the Small Claims procedure. Claims up to €15,000 go to the District Court and up to €75,000 to the Circuit Court.
How quickly do public bodies have to pay suppliers? Public bodies follow a government policy of paying within 15 days of receiving a valid invoice, which is administrative rather than law. The Late Payment Regulations set a 60-day ceiling for public bodies.
Should I offer direct debit to get paid sooner? For customers you bill regularly, direct debit collects on the due date once the customer has signed a mandate, so you're not waiting for them to act. You need to give notice of each collection, 14 calendar days unless you agree otherwise.
