e-Invoicing (KSeF) Implementation

Getting your invoicing ready for Poland's mandatory National e-Invoicing System (KSeF), end to end. We handle the process design, system integration and testing so structured invoices flow correctly before the obligation bites.

What this covers

  • Structured invoice (FA_VAT) schema mapping from current data
  • ERP and invoicing system integration with the KSeF API
  • Authorisation and token management for KSeF access
  • Sales and purchase invoicing process redesign for KSeF
  • Handling of correction, advance and internal invoices
  • Test and pre-production environment validation
  • Attachment and non-structured data workaround handling
  • Offline mode and emergency procedure design
  • VAT and JPK reconciliation against KSeF records
  • Staff training on the new invoicing workflow
  • Documentation of the KSeF operating procedure
  • Coordination with software vendors and integrators
  • Post go-live monitoring and issue resolution
