Payments are moving in the same direction across Europe: faster settlement, richer structured data and direct account-to-account experiences. For finance teams, that means fewer manual files and better reconciliation—but also new standards and deadlines to prepare for.
The latest Fisqal Open Banking update expands payment options and improves payment-file handling directly inside Microsoft Dynamics 365 Business Central. PSD2 is the preferred live connection. MultiLine remains the file-based path when a Luxembourg bank does not offer PSD2. Wero now replaces the previous Payconiq (formerly Digicash) flow on sales invoices.
Points clés
- The PSD2 Open Banking connector is the primary path for bank communication, statements and near real-time cash visibility in Business Central.
- MultiLine remains fully supported for file-based exchange with Luxembourg banks when PSD2 is not available, including SEPA domiciliations and pain.001.001.09.
- ABBL’s ISO 20022 pain.001.001.09 guidelines become mandatory on 14 November 2026; unstructured addresses will no longer be accepted after that date.
- The Wero connector replaces the previous Payconiq (formerly Digicash) flow on sales invoices, with Wero / Payconiq support on single and bulk payments.
- Existing LuxTrust, bank approvals, signing rules and company limits continue to apply. Current customers need no action beyond a supported Business Central version.
Why the Payment Market Is Moving Now
The hottest payment features are not isolated products. They are parts of a wider shift toward open, real-time and data-rich financial infrastructure.
Instant by default
Euro-area banks now offer instant euro transfers around the clock, with pricing no higher than standard transfers.
Safer beneficiary checks
Verification of Payee compares the beneficiary name with the IBAN before standard or instant SEPA transfers are authorised.
API-connected banking
Open Banking APIs bring balances and transactions closer to ERP workflows, reducing portal switching and manual imports.
European payment rails
Account-to-account solutions such as Wero aim to create a consistent European alternative for everyday digital payments.
The New ISO 20022 Format: pain.001.001.09
ISO 20022 itself is not new. What changes for Luxembourg companies is the customer credit transfer initiation message used to send payment instructions to banks. ABBL’s version 3.2 guidelines are based on pain.001.001.09 and cover SEPA credit transfers, SEPA instant credit transfers and other cross-border credit transfers.
Key deadline
14 November 2026
ABBL’s version 3.2 guidelines become mandatory. The older pain.001.001.03 message will no longer be supported.
Address data changes too
Unstructured postal addresses will no longer be accepted after the same date. Payment systems, ERP records and back-office processes must use structured or hybrid address data to reduce errors, improve screening and support straight-through processing.

No action is required from current customers for the new MultiLine payment format. Support for pain.001.001.09 is delivered through the regular Fisqal update path.
From Digicash and Payconiq to Wero
Luxembourg has already seen one major mobile-payment transition: Payconiq acquired Digicash in 2017 and developed the account-to-account payment experience used across the country. The next chapter is European.
The European Payments Initiative acquired Payconiq International and iDEAL to help build Wero: a unified European digital wallet and instant account-to-account payment solution. In Fisqal Open Banking, the Wero connector now replaces the previous Payconiq (formerly Digicash) flow and adds a modern payment option to sales invoices.

What Fisqal Open Banking Does Today
Fisqal Open Banking keeps bank communication, payments and reconciliation closer to your accounting workflows in Business Central. PSD2 is the live API path. MultiLine is the file-based path when PSD2 is not available at your bank.
Direct bank connectivity
Connect bank communication and treasury activities with Business Central through the PSD2 Open Banking connector.
Automatic statement flows
Bring statement information into Business Central without manual file handling, and get faster access to current banking data via PSD2 integration.
Payment initiation
Prepare payment files from Business Central and keep the process connected to your accounting records for both single and bulk payments. Benefit from Wero / Payconiq support.
MultiLine fully supported
Use MultiLine to exchange file-based information with Luxembourg banks when PSD2 is not available — including SEPA domiciliations and the new pain.001.001.09 payment file.
Which banks can you connect?
PSD2 coverage depends on the banks participating in the Open Banking network used by the connector. Review the current participating-bank list before you plan a rollout.

Your controls remain in place
Fisqal Open Banking complements existing treasury controls and approval processes. Bank approvals, signing rules and company limits continue to apply wherever they are configured. LuxTrust authentication is unchanged.
What Finance Teams Should Do Now
The rollout is live through monthly Fisqal solution upgrades. A short readiness check is still worthwhile:
- Keep Business Central on a supported version so monthly solution upgrades can be applied.
- Review customer, vendor and bank-account address data before unstructured addresses are prohibited in November 2026.
- Confirm that treasury approval, signing and company-limit configurations still reflect your current governance.
- Discuss the Wero sales-invoice flow with the teams responsible for receivables and customer experience.
