Setting Up E-Invoicing

This guide explains how to enable e-invoicing in SimplBooks.

How do I enable e-invoicing?
To set up e-invoicing, you can either create a new Apix account or activate an existing Apix account. Both options are available directly within SimplBooks.

What does e-invoicing cost?
Activating e-invoicing is free and there are no fixed monthly fees. Sending and receiving e-invoices is charged on a per-use basis according to SimplBooks’ price list.

1. Activate Apix under Settings > Integrations > Apix


2. If you do not have an existing Apix account, select “New Apix user”

  • Some information will be filled in automatically from the software. Complete the missing details and activate the integration using the Activate button at the bottom of the page.
  • Choose whether you want to enable sending e-invoices, receiving e-invoices, or both.
📢 Note! The email address and password do not need to be the same as those used to log in to SimplBooks. The email address and password you set here are also used to log in to Apix’s Laskumappi (Invoice Folder) service when needed.

3. You can also connect an existing Apix account to SimplBooks by selecting “Existing user”

  • Enter the email address and password that serve as your username.

4. If you also enable receiving e-invoices, after activation you can view your company’s e-invoice addresses under Settings > Integrations > Apix > Settings.
