Although SWIFT has created a large coexistence period for both old and new payment standards, the migration is not eased by the adoption of multiple strategies for each payment market infrastructure. Our customers have lived with the frustration of business discontinuity when the connection to their partner banks was suddenly gone. We started helping SMEs in Switzerland back in 2016 when the country was migrating ahead from the traditional ESR, DTA, EZAG, and DD standards. We worked with Six standards and implemented various financial message translators and converters that allowed dozens of businesses to keep working. We gradually added features for payment initiation, validation, transformation, invoice reconciliation, and finally Swift API integration for financial institutions.
