The new reality

The new rules take effect. Your company must be able to issue, receive and process electronic invoices correctly.

What is changing

  • new electronic invoicing obligations
  • certified service providers and new data flows
  • Peppol, XML and structured data
  • impact on accounting, ERP and internal processes
  • risk of penalties if you are unprepared

What your company needs to do

  • check the readiness of your accounting and ERP systems
  • set up issuance, receipt, validation and posting
  • assign responsibilities across your team, accountant and IT
  • review your software provider’s implementation plan
  • test the process before the obligation takes effect

The sooner your company understands its specific scenario, the less chaos, manual work and risk of errors it will face when implementing e-Invoicing.
