How to cancel Fortnox by mail
Get your account details together
Check the account email, the plan or product name and the invoice or order number from your latest receipt before anything else. A request that does not match the account on file at Fortnox is the easiest one to set aside.
Prepare the letter
Fortnox is based in Sweden, so the letter goes out in Swedish, built from our Swedish template. Subject line: “Ämne: Begäran om uppsägning – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post it with proof of delivery
Send the letter to the Växjö mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Fortnox was told. Compare it with your statements over the next billing cycle.
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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
