SEPA direct debit in Ireland: the complete guide for small businesses

SEPA direct debit lets an Irish business collect an agreed payment straight from a customer's euro bank account, on a date the customer has been told about, once that customer has signed a mandate. Every collection needs a signed mandate, a creditor identifier and advance notice, which is 14 calendar days unless you and the customer agree otherwise. Customers can ask their bank for a refund of any authorised collection within eight weeks, so it suits regular payments people expect.

The short version

• SEPA direct debit needs a signed mandate, a creditor identifier and advance notice.
• Notice is 14 calendar days before collection unless you agree a shorter period.
• Customers can ask for a refund of authorised collections within eight weeks.
• A mandate lapses if you present no collection under it for 36 months.
• Customers moving to Adfin from another SEPA provider keep their existing mandates.

How SEPA direct debit works

With a direct debit, you start the payment rather than waiting for your customer to send it. Your customer signs a mandate once, giving you permission to collect from their euro account, and after that each collection goes through to their bank on a date you've told them about in advance. They don't have to remember to pay, log in to their banking app or copy a reference from an invoice.

The scheme rules come from the European Payments Council's SEPA Direct Debit Core Rulebook. You'll rarely need to read it, but four of its rules shape how you run direct debit day to day, and they're covered below: the mandate, the creditor identifier, the notice period and the customer's refund rights.

There are two ways to collect, and they put different amounts of work on you. You can go to your own bank and set yourself up as a direct debit originator, which involves preparing collection files and sending them to the bank on time. Or you can use a payment provider, which handles the collection side for you.

What you need before your first collection

The first requirement is a signed mandate from each customer. It's the customer's authorisation for you to collect, and without one a collection can be challenged as unauthorised. Keep every mandate on file for as long as you're collecting under it, and for some time after, because it's your evidence if a customer later disputes a payment.

You also need a creditor identifier on every collection. In Ireland it's issued by the business's bank and runs to 13 characters, in a format like IE97ZZZ123456. If you collect through your own bank, you get one when the bank sets you up. If you use a payment provider, ask whether collections go out under the provider's identifier or your own, and whose name your customers will see on their bank statements. With GoCardless, for example, showing your own business name on customers' statements is a paid add-on at €50 a month.

The rulebook also requires you to send a pre-notification at least 14 calendar days before each collection's due date, unless you and the customer agree a different timeline. The notice doesn't have to be a separate letter. It can go on the invoice, so one document tells the customer what they owe and when it will be taken.

If you want collections to happen sooner after you invoice, put a shorter notice period in your terms and get the customer's agreement to it when they sign up. That way, when you change your prices or a bill varies from month to month, you're not stuck waiting a fortnight after every invoice.

When the money leaves the customer's account

Here's how the dates work for a monthly fee due on Monday 1 March 2027.

• By Monday 15 February, the customer needs their notice, 14 calendar days ahead (or whatever shorter period you've agreed).
• By Friday 26 February, the collection has to reach the customer's bank. The rulebook requires it to arrive at least one inter-bank business day before the due date, whether it's a one-off or a recurring collection.
• On Monday 1 March, the payment is taken from the customer's account.

If you use a payment provider, it handles the second date for you. If you submit through your bank, you'll be working to the bank's own cut-off time on the business day before, so build in a margin for bank holidays and weekends. The practical upshot is that you set your billing date first and work backwards to the date the notice goes out.

Refunds, returns and failed collections

SEPA direct debit gives customers strong refund rights, and it helps to plan around them from the start. A customer can ask their bank to refund any authorised collection within eight weeks of the debit date, with no questions asked. If they say a collection wasn't authorised at all, they have up to 13 months from the debit date to claim. Your signed mandate is what shows the collection was authorised.

Separate from refunds, a collection can come back to you as a return or a reject, for reasons such as insufficient funds in the customer's account or an account that has been closed. A reject happens before the money moves between banks and a return after, but either way you haven't been paid and need to contact the customer.

When a collection fails, some providers charge you for it. Stripe, for example, lists €3.50 for a failed SEPA payment and €15 for a SEPA dispute, and makes SEPA funds available six business days after the charge. One practical next step after a failed collection is to send the customer a payment link so they can pay by card or bank transfer while you sort out the mandate.

One more rule catches businesses with seasonal or occasional customers. If you don't present a collection under a mandate for 36 months, it lapses and you need a fresh one before you collect again.

What collecting by direct debit costs

Banks and providers price direct debit differently, so work out what your own mix of payments would cost before you choose. Adfin charges 20c + 1% per successful payment. The 1% part is capped at €2 on SEPA direct debit and bank transfer, so for amounts up to €2,000 those payments never cost more than €2.20. Card payments have no cap. There's no monthly fee, no setup fee and no contract.

In this table, below €200 the method makes no difference to the fee. Between €200 and €2,000, direct debit stays at €2.20 while the card fee keeps rising with the amount.

As a worked example, take an accountancy practice collecting a €450 monthly fee from 40 clients. By direct debit, each collection costs €2.20, so the month costs €88. If the same clients paid the same fee by standard card, each payment would cost €4.70 (€4.50 plus 20c), or €188 a month. Over a year, that's €1,056 against €2,256 for exactly the same fees.

The fee per payment isn't the only cost to compare. GoCardless takes its fees out of your payouts, so the money that lands in your account is less than what you collected, and it doesn't take card payments at all. Also check what each provider charges when a collection fails, whether there's a monthly fee, and whether you can show your own business name without paying extra.

Which payments suit direct debit

Direct debit works best where the customer expects to pay you regularly and agrees to it once. Monthly retainers, membership fees, subscriptions, service charges, maintenance contracts and recurring professional fees all fit. Once the mandate is in place, you don't depend on the customer remembering to pay, and you're not chasing a transfer that was set up with the wrong reference.

It's less suited to one-off jobs, where asking for a mandate adds a step for a single payment. For those, a payment link by email, SMS or WhatsApp, which the customer can pay by card, Apple Pay, Google Pay or bank transfer, usually gets the money in with less effort on both sides. You can also use both, with a link for the first invoice or one-off work and a mandate once the customer becomes a regular.

With Adfin, customers can pay by SEPA direct debit, card, Apple Pay, Google Pay or bank transfer, and payment links go out by email, SMS or WhatsApp. If you use Xero or QuickBooks, Adfin is a certified app for both with two-way sync, so a payment collected through Adfin is marked paid in your accounts automatically.

How to move existing mandates to a new provider

Changing who collects for you doesn't have to mean asking every customer to sign again. GoCardless's own guide to transferring SEPA mandates says mandates move between providers when the creditor identifier is updated, that customers don't need to give consent again or set up a new mandate, and that they must be told about the change before the next payment, with the transfer taking effect on the next collection.

If you move your direct debits to Adfin from another SEPA direct debit provider, your customers keep their existing mandates and don't sign again. The mandate moves with the next collection, and your customers are told before it. On your side, the work is agreeing a date, making sure no collections are in flight with the old provider on that date, and checking that your customer list and amounts are right before the first collection under the new set-up.

Common questions

Do I need a creditor identifier to collect SEPA direct debits in Ireland? Every collection carries a creditor identifier, a 13-character code issued by a bank, such as IE97ZZZ123456. If you collect through your own bank it issues yours, and if you use a payment provider, ask whether collections go out under its identifier or your own.

How much notice do I have to give before a SEPA direct debit? The rulebook requires a pre-notification at least 14 calendar days before the due date, unless you and the customer agree a different period. The notice can go on the invoice itself.

Can a customer reverse a SEPA direct debit? A customer can ask their bank to refund any authorised collection within eight weeks of the debit date, without giving a reason. For a collection they say they never authorised, they can claim for up to 13 months.

How long does a SEPA mandate last? A mandate stays usable while you keep collecting under it. If you don't present a collection for 36 months, it lapses and you need a new signed mandate before collecting again.

What happens if a SEPA direct debit fails? A collection can be rejected or returned for reasons such as insufficient funds or a closed account, and you won't receive the money. Contact the customer, and consider sending a payment link so they can pay another way while the mandate is sorted.

Can I change direct debit provider without customers signing new mandates? Whether customers have to sign again depends on the providers involved, so ask the provider you're moving to before you set a date. Either way, tell customers about the change before the next collection.
