If you do not want to receive eInvoices in Vipps, turn this off in the Vipps app, using menu option “Receive bills in Vipps”. You will continue to receive eInvoices in DNB online bank.
Note that the “on/off” button in “Receive bills in Vipps” remains independent of the “on/off” button in the “Always Vipps eFaktura (eInvoice)” under “eFaktura (eInvoice) in online bank and apps”. This means that if you turn off the first button, you will only stop receiving a bill notification in the Vipps app, but you will still be on “Vipps eFaktura (eInvoice)” or “Always eFaktura (eInvoice)”. To switch off the latter, you need to switch off “Always Vipps eFaktura (eInvoice)” by itself.
You will then not receive eFaktura (eInvoice) requests in DNB the online/mobile banks either, or in any other banks, unless you have entered into a specific agreement on eFaktura (eInvoice) with a provider/company.
