Companies with their own accounting system
Keep working in your accounting system. Once it is connected, the Access Point delivers your e-invoices in the background.
How does the Access Point become part of your system?
Connect your system to the Access Point
You can connect your accounting system to the Flowis Access Point via an API. It is a technical connection through which the two exchange e‑invoices automatically.
Invoices are transferred automatically
We transfer received e-invoices into your system and deliver the ones you issue to your customers. You don’t have to download them or move them between applications by hand.
You work in a familiar environment
You keep processing e‑invoices in your accounting system just as you are used to. The Flowis Access Point takes care of their delivery in the background.
How does an e-invoice travel once you are connected?
One connection for both directions. The Access Point takes care of delivery, and you work with invoices in your own system.
A received invoice arrives right in your system.
The supplier sends it through their Access Point. Flowis receives it and transfers it via the API into your accounting system for further processing.
An issued invoice leaves straight from your system.
You create it in your system. Via the API it is passed to the Flowis Access Point, which delivers it to your customer.
