You're wasting time chasing invoices

Every month, the same story:

follow-up emails to get the documents
invoices arriving as PDFs, photos, sometimes via WhatsApp
incomplete files at closing time
manual data entry that could be avoided

Your clients already use Peppol Box or Flexina? Their invoices can reach you without them lifting a finger.

Flexina Sync handles it all

The app connects to your clients' Peppol Box and Flexina accounts and syncs their documents to your computer.
