This article is for merchants currently using Vipps Checkout. If you are using Vipps as a payment method through a different checkout solution, this article does not apply to you. Read more here instead.
You can also find answers to frequently asked questions about the switch at our FAQ on kustom.co.
Overview
When you switch from Vipps Checkout to Kustom Checkout, there are two account setup steps that may apply to you:
adding bank details for payouts and,
submitting Know Your Customer (KYC) information
Neither is complicated, but missing either one can delay your payouts — so it's worth getting them sorted early.
Add a bank account for each currency you sell in
Kustom does not convert currencies for payouts. That means you need a registered IBAN for every currency you accept orders in.
If you sell in multiple currencies and only register one account, you will not receive payouts for the currencies that have no matching IBAN on file.
For example, if you sell in both NOK and SEK but only have a registered IBAN for NOK, your SEK transactions will not be paid out.
To add a bank account:
Open Kustom portal and sign in
Navigate to Settings in the left menu
Scroll down to Payout details
Click Add bank account
Enter your account details in IBAN format and save
A few things to keep in mind:
Only IBAN accounts are accepted. Bankgiro and Plusgiro are not supported.
If you are switching from a Vipps payout account that used a local format, you will need to provide an IBAN equivalent.
Accounts issued by Svea Bank need to have a unique IBAN.

You may need to submit Know Your Customer information
As part of switching to Kustom, you may be asked to verify your identity or provide business documentation through the Kustom portal.
This is a legal requirement — Kustom must comply with KYC regulations to process payments on your behalf. The information is handled by Kustom's payment partner, Stripe.
You may be asked to provide:
Proof of identity (passport, driver's license, or national ID)
Proof of personal address (utility bill, bank statement, or government-issued letter — issued within six months)
Business or organizational documentation (registration certificate, articles of association, or similar)
Documents must be clear and unedited, and the name and address must match exactly what is registered in your Kustom account. If there is a mismatch, update your account details in Kustom portal to match the document rather than submitting a document that does not match.
Common reasons documents are rejected:
Blurry or out of focus — the document must be fully legible. If a machine cannot read the text, it will be declined.
Glare or shadows — reflections from laminated IDs or passports are a frequent cause of rejection. Photograph in flat, even light.
Cropped or cut off — all four corners of the document must be visible.
Expired document — make sure the ID or passport is still valid at the time of submission.
Black and white scan — color is required.
Document is too old — proof of address documents must have been issued within the last six months.
Name or address mismatch — the details on the document must match exactly what is registered in your Kustom account inside the Kustom portal.
If payouts have not started and you are not sure why, checking whether there are outstanding KYC items in the portal is a good first step.
