The Single Euro Payments Area (SEPA) marked one of the most ambitious milestones in the economic integration of the European Union. Now, with the entry into force of the new regulations, the SEPA Direct Debit system has evolved from a mere technical standard into an advanced security ecosystem.
In this practical guide, we outline the pillars of the current regulations, the legal significance of the mandate, and how businesses can safeguard their liquidity against the risk of chargebacks through robust digital management.
Introduction to the SEPA system: Beyond European regulations
Currently, any business operating under the SEPA standard has access to a unified market of over 36 countries operating under a single financial language. But that does not mean SEPA is set in stone. In the European market, digitalisation has accelerated the transition to processes where the legal validity of the mandate and the quality of technical data are the only guarantees that a collection is permanent.
Its impact on corporate treasury
So, what is the impact of SEPA on any company? How does it affect day-to-day operations? The answer is simple, yet comprehensive: at a corporate level, SEPA is not merely a format that companies are obliged to use; rather, it is a powerful tool for centralising liquidity.
Thanks to this and a set of uniform rules, businesses can operate across Europe using a single bank account, ensuring lower transaction costs and streamlined bank reconciliation.
The Legal Framework in 2026: A New Direction in Security
Although Regulation (EU) No 260/2012 laid the foundations for SEPA, in recent years this system has undergone significant changes to adapt to the digital age, always seeking to protect businesses and customers through three pillars and a mandatory technical update:
Universalisation of Instant Payments (Regulation 2024/886)
By 2026, ‘standard’ transfers will no longer differ from ‘instant’ transfers. This regulation requires financial institutions to offer the ability to send and receive transfers in under 10 seconds, 24 hours a day, 7 days a week, ensuring that such transfers do not cost more than standard transfers. The aim is for instant transfers to become the standard, gradually replacing traditional ones.
Towards PSD3 and the PSR
The new Payment Services Regulation (PSR) strengthens the fight against fraud, introducing stricter liabilities for banks in cases of identity theft (‘spoofing’ fraud).
Mandatory Validation through Beneficiary Verification
From October 2025, it will be mandatory to verify account ownership before processing the first direct debit, thereby drastically reducing erroneous payments.
Technical alert: The new ISO 20022 standard (Structured Addressing)
A key change in 2026 is the transition to the ISO 20022 XML format. Until now, mandates were processed using addresses in a single line of text, which significantly increased the risk of failed collections and bank charges due to technical rejection. To address these issues, financial institutions now require that information include structured addresses: street, number and postcode in separate fields. The use of single-line addresses will be prohibited from November 2026.
SEPA payment instruments: Choose the right tool
Not all SEPA instruments are suitable for every business model. Choosing one instrument over another should not be a random decision; it must be a strategic choice based on a set of financial criteria. Otherwise, our choice could hamper our business’s cash flow.

- SEPA Credit Transfer (SCT): Used for payments to suppliers and payroll. The transfer is standard. Its main advantage is that the customer or payer has full control.
- Instant Credit Transfer (SCT Inst): Payments that the beneficiary needs to receive immediately. Funds are available in under 10 seconds, 24 hours a day, 365 days a year.
- SEPA Direct Debit (SDD): Used for recurring payments such as subscriptions, electricity or utilities. The advantage is that the collection process is automated via prior authorisation.
It should be noted that not all direct debits offer the same legal certainty. The choice between the Core and B2B schemes will determine the stability of the cash flow:
- Core Scheme: Universal and mandatory for all banks. This is the scheme that allows for an unconditional refund period of 8 months. It is ideal for the mass market (B2C).
- B2B Scheme: Exclusive to transactions between businesses or self-employed individuals.
What is the difference between SEPA and a direct debit mandate?
The terms “SEPA” and “SEPA direct debit mandates” are often used interchangeably, as they are generally thought to be synonymous, but nothing could be further from the truth. Operationally, they represent different aspects of the cycle.
Firstly, SEPA refers to the ecosystem itself. Put simply, it explains the “how” and “where” money moves; in other words, its function is to define the technical aspects (ISO 20022 XML formats) and the timelines (when the money must arrive).
To make it easier to understand, imagine it as the road network connecting all parts of Europe and along which money travels. In this sense, it stipulates that a transfer between Seville and Paris must be processed at the same speed and cost as one between Seville and Madrid.
In contrast, the SEPA Mandate is the private document between the creditor and the debtor, which legitimises each individual transaction within that network, and through which the payer authorises their bank to make a direct debit. Without this document, the SEPA ecosystem would continue to function, but any company using it would be committing an illegal act or, at the very least, would be acting without authorisation. It answers the questions ‘why’ and ‘with what permission’ the payment is initiated; and it is the customer who grants the authorisation and who can revoke it at any time.
As well as authorising the payment, it informs all parties of their rights and obligations, fostering trust between the various parties involved.
Why does this distinction matter in 2026?
Knowing a customer’s IBAN does not give any institution the right to charge them. Without the mandate—the legal basis—any charge is an ‘unauthorised transaction’, which opens the door to chargebacks for over a year.
Mandatory information that a mandate must contain
The format of SEPA mandates is regulated by the EPC, which also provides for electronic versions known as e-mandates. The minimum elements it must contain are:
- Creditor details: name and identifier in the SEPA system.
- Debtor details: name, address, IBAN and BIC codes, and signature.
- Mandate information: unique reference code, authorisation date and type of payment scheme.
It must also include information for the customer, such as:
- That this is a direct debit.
- That it constitutes authorisation to make collections, as well as their rights to a refund.
What risks can the SEPA Direct Debit Mandate entail?
Operating without a correctly completed SEPA Direct Debit mandate can expose the company to serious risks, ranging from administrative penalties for breaching data protection and mandate management regulations to the bank revoking its ability to issue direct debits.
For their part, SEPA Mandates in commercial transactions protect the end customer against any unforeseen events or errors that may arise, ensuring that they always retain control over their funds. This balance of rights is what makes direct debit one of the most reliable methods in the world.
The SEPA system is designed so that the payer never feels unprotected, distinguishing between two types of situations: satisfaction and control guarantees, and protection against unauthorised transactions.
Viafirma and its contribution to SEPA Direct Debits
At Viafirma, we understand the importance of SEPA Direct Debits in the day-to-day activities of businesses and individuals. That is why our solutions are perfectly tailored to this type of document.
We have specific pre-designed templates for SEPA direct debits, ready to be completed and sent immediately. These templates are customisable and allow for the inclusion of additional evidence in accordance with the security policies defined by the user, such as biometric verification or one-time passwords (OTP).
With these tools, we are helping to drive the development of the European digital market, bringing greater reliability and efficiency to payment and collection processes across the SEPA area.
