How it works

  • You tell us which package you use. We set up the connection for you.
  • For a configured accounting integration, we agree how sales invoices, credit notes and customer records are passed to your accounts.
  • Fikst records the transfers made by that accounting integration. You can retry a failed transfer.
  • We agree how your administration is connected and what access is needed.

Is your package not listed? We build the connection for you.
