Imagine the scene: you receive an urgent call from your treasury department. An international payment has just been rejected. No clear explanation. The supplier is awaiting payment. You contact your bank, which tells you: “Your flows do not comply with the ISO 20022 standard<\/strong>.” <\/p>\n

Many companies will experience this scenario as early as November 2026<\/strong> if they have not anticipated their migration to structured payment formats. The good news? There’s still time to act. Here’s how. <\/p>\n

[\/et_pb_text][et_pb_text _builder_version=”4.27.5″ custom_padding=”||||false|false” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n

ISO 20022: definition and challenges for finance departments<\/h2>\n

[\/et_pb_text][et_pb_text _builder_version=”4.27.5″ custom_padding=”||5%||false|false” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n

What is ISO 20022?<\/h3>\n

ISO 20022<\/strong> is an international financial messaging standard<\/strong> designed to harmonize and modernize exchanges between banks, companies and payment infrastructures. Unlike previous formats (SWIFT MT, CFONB, AFB320), it is based on an enriched XML language<\/strong>, enabling much more structured information to be transmitted. <\/p>\n

In concrete terms, ISO 20022 makes it possible to :<\/p>\n

    \n
  • Reduce errors and rejected payments<\/li>\n
  • Improve regulatory compliance (KYC, anti-money laundering, sanctions)<\/li>\n
  • Facilitate automated transaction processing<\/li>\n
  • Enhancing the traceability and transparency of financial flows<\/li>\n<\/ul>\n

     <\/p>\n

    Why is this migration essential?<\/h3>\n

    This standard is gradually being adopted worldwide for all types of flows: SEPA credit transfers, cross-border payments, collections, interbank messages. The old formats will be definitively abandoned, making migration compulsory<\/strong> for all companies making international payments. <\/p>\n

    [\/et_pb_text][et_pb_text _builder_version=”4.27.5″ custom_padding=”||||false|false” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n

    November 2026: the critical deadline for structured addresses<\/h2>\n

    [\/et_pb_text][et_pb_text _builder_version=”4.27.5″ custom_padding=”||||false|false” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n

    The ISO 20022 migration timetable is accelerating. While banks have finalized their transition by November 2025, companies have until November 18, 2026<\/strong> to comply with a major requirement: theban on unstructured addresses<\/strong> in payment messages. <\/p>\n

     <\/p>\n

    End of MT101\/MT103 and AFB320 formats<\/h3>\n

    From this date, the old file formats (SWIFT MT101, MT103, AFB320) will be replaced by XML pain.001<\/strong> (Payment Initiation) files<\/strong>.<\/p>\n

    This change requires new rigor in the structuring of data, particularly beneficiary addresses.<\/p>\n

     <\/p>\n

    The 3 ISO 20022 address structuring levels<\/h3>\n

    ISO 20022<\/strong> defines three address formats:<\/p>\n

      \n
    • Unstructured address<\/strong>\n
        \n
      • All information in a free text block<\/li>\n
      • Example: “123 rue de la Paix, 75008 Paris, France”.<\/li>\n
      • Banned from November 2026<\/strong><\/li>\n<\/ul>\n<\/li>\n
      • Hybrid address (authorized)<\/strong>\n
          \n
        • City and country in dedicated tags<\/li>\n
        • The rest is free text<\/li>\n
        • Acceptable temporary solution<\/strong><\/li>\n<\/ul>\n<\/li>\n
        • Structured address (recommended)<\/strong>\n
            \n
          • Each element in its own XML tag<\/li>\n
          • Separate street number, street name, zip code, city, country<\/li>\n
          • Optimum format to avoid rejects<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

            [\/et_pb_text][et_pb_text _builder_version=”4.27.5″ background_color=”#f7fbff” custom_margin=”||8%||false|false” custom_padding=”5%|5%|5%|5%|true|true” border_radii=”on|23px|23px|23px|23px” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n

            Please note<\/strong>: Although hybrid addresses are still permitted, they may be rejected depending on the requirements of certain banks or countries. The structured address is the only guarantee of total compliance to secure your payments over the long term. <\/p>\n

            [\/et_pb_text][et_pb_text _builder_version=”4.27.5″ custom_padding=”||||false|false” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n

            Why do companies underestimate this migration?<\/h2>\n

            [\/et_pb_text][et_pb_text _builder_version=”4.27.5″ custom_padding=”||5%||false|false” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n

            A project wrongly perceived as purely IT<\/h3>\n

            ISO 20022 migration<\/strong> is still too often seen as a technical project for the IT department. This is a strategic error<\/strong>. This subject primarily concerns finance departments<\/strong>, and more specifically : <\/p>\n

              \n
            • Treasury and cash management<\/strong> teams<\/li>\n
            • Procure to Pay (P2P<\/strong>) departments, responsible for scheduling outgoing flows<\/li>\n
            • Departments in charge of supplier, intercompany and treasury payments<\/strong><\/li>\n<\/ul>\n

               <\/p>\n

              The mistake of waiting for a signal from your banks<\/h3>\n

              Many companies adopt a wait-and-see attitude: they hope their banks will alert them early enough, or that the deadline will be postponed.<\/p>\n

              This strategy is risky<\/strong>. The banks have finalized their own migration in November 2025. They are under no obligation to support you in yours. And the November 18, 2026<\/strong> deadline is firm: neither SWIFT nor the EPC (European Payments Council) are planning any postponements. <\/p>\n

              The risk? A cascade of rejected payments as early as November 2026, with a direct impact on your cash flow and supplier relations. <\/p>\n

                  • Map your payment systems (ERP, TMS, treasury software)<\/li>\n
                  • Auditing your third-party repositories: how many beneficiaries? What data quality? <\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                    \ud83d\udca1 Our Council<\/strong>: This phase must involve the IT department, but also and above all the business teams (treasury, P2P, accounts payable).<\/p>\n

                     <\/p>\n

                    2. Cleaning & enrichment of third-party repositories<\/h3>\n

                        • Update your third-party repository in your ERP or TMS<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                          \u26a0\ufe0f Points to watch<\/strong>: This is often the longest and most underestimated project.<\/p>\n

                           <\/p>\n

                          3. Upgrade your payment systems (ERP\/TMS)<\/h3>\n
                            \n

                              • Check that your ERP or TMS supports the pain.001 format (versions v3 or v9)<\/li>\n
                              • Adapt your validation and scheduling workflows<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                                \ud83d\udca1 O ur Council<\/strong>: Some ERPs require upgrades or add-on modules. Anticipate deployment times. <\/p>\n

                                4. Be proactive with your banking partners<\/h3>\n

                                      \u26a0\ufe0f A word of caution<\/strong>: Not all banks are at the same level of maturity. Some will temporarily accept hybrid addresses, others will not. <\/p>\n

                                       <\/p>\n

                                      5. Plan and test all your flows<\/h3>\n
                                        \n

                                          • Test each type of flow (SEPA, international, inter-company)<\/li>\n
                                          • Test with each partner bank<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                                            \ud83d\udca1 O ur Council<\/strong>: Plan several waves of testing between June and October 2026. Don’t test at the last minute. <\/p>\n

                                             <\/p>\n

                                            6. Anticipate cascading discharges<\/h3>\n
                                              \n
