The verdict in three sentences
A services company billing 1,400 monthly subscriptions of EUR 80 to 600 by bank transfer typically suffers 9% late payments, and every reminder costs finance time. Integrating SEPA Direct Debit with e-mandates costs EUR 8,000 to 20,000 in Dublin, with fees of 0.35 to 1% per collection, capped. Expected result: late payments under 2% and about 15 days of cash flow gained, from the second billing cycle.
SEPA providers and fees compared in 2026
Three routes exist: go through your bank (creditor ID and SEPA files generated yourself), or use a payment provider that handles mandates, notifications and failures.
| Solution | Fee per collection | Cap | E-mandate | Failure handling |
|---|---|---|---|---|
| GoCardless (standard) | 1% + EUR 0.20 | EUR 4 per transaction | Yes, native | Smart retries in Pro plan |
| Stripe SEPA Direct Debit | EUR 0.35 flat | n/a | Yes | Webhooks, dunning to build |
| Mollie SEPA | EUR 0.25 to 0.35 | n/a | Yes | Basic |
| Bank (pain.008 XML file) | EUR 0.20 to 0.50 + EUR 20 to 60 monthly | n/a | Signature to organise | Manual, bank return files |
| Slimpay | On quote, often EUR 0.30 to 0.60 | Negotiated | Yes | Advanced |
On an average invoice of EUR 220, GoCardless caps at EUR 4, or 1.8%, while Stripe stays at EUR 0.35. For high, regular amounts, Stripe or the bank is cheaper, but GoCardless reduces failures with retries timed around paydays.
What the integration includes and what it costs
Dublin development rates (EUR 650 to 950 a day) sit above French ones, which explains the higher range.
| Component | Scope | 2026 price (EUR, excl. VAT) |
|---|---|---|
| E-mandate | IBAN form, signature, confirmation email, SEPA B2B or CORE compliance | 2,500 to 5,000 |
| Billing sync | Connection to Xero, Sage, Chargebee or in-house tool | 2,500 to 6,000 |
| Webhooks and statuses | Paid, failed, disputed, customer account updates | 1,500 to 3,500 |
| Automated dunning | Email sequence after failure, retry, service suspension | 1,000 to 2,500 |
| Migrating existing customers | Mandate signing campaign, conversion tracking | 500 to 1,500 |
| Collections dashboard | Expected receipts, failures, DSO | 1,000 to 2,500 |
One key distinction: a SEPA B2B mandate prevents the customer from disputing an authorised debit, but their bank must register it, which slows setup. A CORE mandate is signed online in a minute, with an 8-week refund right. Most Irish SMEs start with CORE.

Aoife, CFO of an IT services company in Dublin, bills 1,400 subscriptions at EUR 220 on average, or EUR 308,000 a month.
- GoCardless + Xero + dunning integration: EUR 14,000.
- Fees: 1,400 x EUR 2.40 (1% + EUR 0.20) = EUR 3,360 a month, or EUR 40,300 a year. With Stripe at EUR 0.35: EUR 5,900 a year, but dunning must be built.
- Late payments: from 9% to 2%, so 98 fewer invoices to chase each month. At 20 minutes each and EUR 45 an hour, about EUR 17,600 a year.
- Cash flow: 15 days gained on EUR 308,000 a month, roughly EUR 150,000 of working capital released, or EUR 7,500 interest at 5%.
Order-of-magnitude 2026 result: with Stripe, the project pays back in under 7 months. With GoCardless, the outcome depends on the real failure rate.
FAQ
How many customers agree to sign a SEPA mandate? In B2B services, 70 to 85% sign within 2 months when the mandate replaces bank transfer, with personalised follow-up.
Do we need a SEPA Creditor Identifier? Yes if you go through your bank, obtained in 1 to 3 weeks. With GoCardless or Stripe, the provider can collect under its own identifier.
What happens when a debit fails for insufficient funds? The bank may charge EUR 5 to 15 in failure fees. A retry 3 to 5 days later recovers 60 to 70% of amounts.
Can we collect variable amounts? Yes, provided the customer is notified at least 14 days in advance, reducible to 2 days if the contract says so. The emailed invoice serves as notification.
Does SEPA work for customers outside the eurozone? Yes for the 36 SEPA countries, including the UK and Switzerland, as long as you bill in euros.
