Key takeaways
- SEPA Direct Debit is the euro-denominated automated collection method, governed by the European Payments Council schemes.
- No collection is possible without a mandate signed by the client, carrying a creditor identifier and a mandate reference.
- Two schemes coexist: Core, open to everyone, and B2B, for businesses only and with no refund after an authorised debit.
- The creditor notifies the client at the latest 14 calendar days before each due date.
SEPA Direct Debit: getting paid without chasing
When a client pays by credit transfer, they trigger the payment, on the date that suits them. SEPA Direct Debit reverses that: once the mandate is signed, it is you, the creditor, who pulls the amount due on the agreed date. For a Belgian business that invoices regular amounts, subscriptions, maintenance contracts, recurring fees, it is the most direct way to get paid without chasing each invoice.
The technical term is SEPA Direct Debit (SDD). SEPA is the Single Euro Payments Area, in which a collection works the same way in Belgium, France or Germany. The framework is set by Regulation (EU) No 260/2012, which establishes technical and business requirements for credit transfers and direct debits in euro, and the operating rules are published by the European Payments Council (EPC).
This article covers what a mandate contains, what sets the Core and B2B schemes apart, how to set up a collection, and what rights your client keeps. For managing the due dates upstream, see also payment terms between businesses in Belgium.
The SEPA mandate: the legal basis of the collection
No SEPA Direct Debit exists without a mandate. It is the document by which your client authorises you to debit their account and authorises their bank to honour those collections. Without it, the debtor's bank rejects the operation. The mandate is both your title to collect and the evidence to keep if a debit is ever disputed.
Two identifiers structure every collection. The SEPA creditor identifier (CI) is assigned to you through your bank and designates you uniquely across the SEPA area. The unique mandate reference (UMR) identifies each individual mandate; you generate it and keep it for the life of the relationship.
What a valid SEPA mandate contains
The debtor's identity and IBAN
The client authorising the collection and the account to debit.
Your SEPA creditor identifier (CI)
Obtained through your bank; it identifies you as the creditor on the network.
The unique mandate reference (UMR)
An identifier specific to this mandate, which you generate and keep.
The payment type
Recurrent (several collections) or one-off (a single one).
The debtor's signature and the date
Electronic or handwritten; without it the mandate is void.
A mandate that goes unused for 36 months lapses: after that period with no collection, a new one must be signed before collections resume.
SDD Core or SDD B2B: two schemes, two logics
The EPC publishes two separate sets of rules. The Core scheme is the basic direct debit, open to all debtors, consumers and businesses alike. The B2B scheme is reserved for collections between businesses: it is usable only if your client is a professional, and it rests on waiving the refund right in exchange for more secure handling for the creditor.
The decisive difference is the refund. Under Core, the debtor can reclaim an authorised collection for eight weeks, with no justification required. Under B2B, that right does not exist once the debit has gone through: in return, the debtor's bank checks the mandate before paying, and the client must have confirmed it with them.
| SDD Core | SDD B2B | |
|---|---|---|
| Consumer debtors accepted | ||
| Business debtors accepted | ||
| Refund of an authorised debit | 8 weeks | None |
| Mandate confirmed by the debtor with their bank | ||
| Mandate checked by the debtor's bank |
The choice depends on your client base. If you collect from consumers or a mix of clients, Core is the one. If you collect from businesses only and want to rule out a late refund, B2B is built for that, provided the client agrees to pass their mandate to their bank.
pre-notification
at the latest before the due date, unless agreed otherwise
Core refund
for an authorised collection, no reason needed
unauthorised collection
window to dispute a debit without a valid mandate
Setting up a SEPA Direct Debit, step by step
The set-up follows a precise order. It always starts with your bank, which issues the creditor identifier, and ends with a flow of collections your software generates in the right format.
- 1
Obtain your creditor identifier
PrerequisiteRequest your CI from your bank and sign the creditor direct debit agreement.
- 2
Have the mandate signed
Before the 1st collectionThe client completes and signs the mandate (Core or B2B). Under B2B, they also pass it to their own bank.
- 3
Pre-notify each due date
Before each debitTell the debtor the amount and the date at the latest 14 calendar days before the collection.
- 4
Issue the collection file
At the due dateYour software produces the order in the expected format and sends it to the bank within the scheme's deadlines.
- 5
Reconcile the collections
After the debitMatch each collection received to the matching invoice and handle any rejections.
Pre-notification is not an optional formality: it gives the client time to fund the account and cuts rejections for insufficient balance. An invoice, an announced due date, a collection: the sequence stands as evidence if the debit is ever disputed.
Track your collections without re-keying
YouInv generates your compliant invoices, tracks payments and reconciles your bank collections in a few clicks.
What direct debit changes for your cash flow
The benefit is one sentence: you no longer depend on the client's goodwill to be paid on the planned date. For recurring revenue, that transforms the predictability of your cash flow and removes much of the chasing. Each due date leaves automatically, and only rejections need action.
The trade-off is discipline. An invalid mandate, a forgotten pre-notification or an unanticipated Core refund can turn a collection into an administrative burden. The right move is to treat direct debit as a tooled process, integrated with your invoicing and bank reconciliation, rather than a string of manual operations.

What is SEPA Direct Debit?
SEPA Direct Debit is the European automated collection method: the creditor pulls an amount from the client's account on the basis of a signed mandate. It relies on the European Payments Council schemes and works identically across the SEPA area, in euro.
What is the difference between SEPA Direct Debit Core and B2B?
The Core scheme is open to all debtors and gives the client a no-questions-asked refund right for eight weeks. The B2B scheme is for businesses only: the client waives that refund right and must confirm the mandate with their own bank.
Is a mandate required to debit a client?
Yes. No SEPA Direct Debit is possible without a mandate signed by the debtor. The mandate authorises the creditor to collect and the client's bank to debit the account; it carries a SEPA creditor identifier and a unique mandate reference.
How far in advance must the client be notified of a collection?
The creditor sends a pre-notification to the debtor at the latest 14 calendar days before the due date, unless another timeline is agreed between the parties. It states the amount and the date so the client can fund the account.
Can a client get a SEPA collection refunded?
Under the Core scheme, the debtor can request a refund of an authorised collection for eight weeks after the debit, with no reason given. For an unauthorised collection the window is thirteen months. The B2B scheme provides no refund after an authorised debit.
