SEB tightens the rules for its ISO files (XML) regarding payments. To ensure that your payroll payments continue to run smoothly, we have made adjustments to Flex HRM Payroll.
What does the change mean? SEB has announced that they are introducing stricter validations for payout files in the ISO 20022 format. The change specifically concerns how clearing numbers should be handled depending on which recipient bank it applies to (according to the rules in SEB's Message Implementation Guide, section 13). These rules will be strictly applied for payments as of January 2026.
What have we done? We have adjusted the logic of how clearing numbers are exported in the bank file in Flex HRM to meet SEB's new requirements. Please note that this does not affect how you enter bank accounts in Flex HRM, only what is sent to the bank. You must still enter the full bank account number in Flex HRM, including all digits and any leading zeros, as well as the full clearing number (including the extra 5th digit for Swedbank).
What do you need to do? In order for your files to be validated correctly by SEB, it is crucial that you update to Flex HRM version 2025.231 or later. We recommend that you plan the update well in advance of the first payments in January 2026. If you operate via Flex, we will of course arrange the correct version without you having to do anything.
