If you've already cancelled bexio but would like to undo your cancellation, you have two options.
Option 1 - you still have access to bexio.
You can go through the cancellation process again under "Settings" - "Packages / Add-ons / User". You cancellation will then be automatically reset.
Option 2 - you no longer have access to bexio.
Contact bexio support directly (Phone 071 522 00 60, E-Mail: email@example.com) so that we can restore your access.
