How to cancel Webbilling by mail
Gather your account details
Have the account email, the last four digits of the linked bank account or card and the membership tier to hand. The details in the letter need to match what Webbilling has on file.
Put the request in writing
Postbye writes the letter in German from our German template, because Webbilling's address is in Switzerland. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Webbilling to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Send the letter to the Würenlingen mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
File the receipt with the letter. A Webbilling charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Webbilling, check these
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
- Ask for the direct debit or card authorisation to be ended, not only the membership.
- Investment and credit-builder products can have their own steps for closing the underlying account.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
