How to cancel WISO Steuer by mail
Note your account details
Before writing, collect the account email, the plan or product name and the invoice or order number from your latest receipt. WISO Steuer can only act on a request it can match to an account.
Draft the request
Because WISO Steuer is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post the letter
Take the letter to the post office and ask for certified delivery to 57290 Neunkirchen (Siegerland). Keep the tracking number it gives you.
Save the tracking record
File the receipt with the letter. A WISO Steuer 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.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
