If you have decided not to use your company account anymore, you can cancel your Papershift subscription.
The contract can be canceled in compliance with the notice period.
See § 5 of our terms and conditions:
"The notice period is 30 (thirty) days, effective at the end of the calendar month; at the earliest, however, the contract will end as of the termination of the last service package subscribed to."
The termination must be in writing; an email (to [email protected]) from the account admin or the management is sufficient.
