Book payouts from Kustom
Diffa reads Kustom's settlements, fetches the orders behind the lines and books sales, VAT and Kustom's fees with VAT.
How Kustom pays out
Kustom Checkout is a spin-off of Klarna Checkout and the settlements look the same: one settlement per payout with orders, refunds and fees. Diffa fetches each order from Kustom's order management.
Kustom adds Swedish VAT to its fees and reports the VAT as a separate line. Diffa books it as input VAT, as reported.
How Diffa books it
Sales are booked gross and the fees separately. The fee carries Swedish VAT, which is booked as input VAT exactly as the platform reports it. Amounts in other currencies are converted at the Riksbank’s rate on the transaction date. The net sits on the receivable from Kustom until you book the deposit in your accounting software; Diffa never books bank lines.

Common questions
- When are sales booked?
- On the day of the sale. Kustom releases the transactions with the payout, so the vouchers are created then but dated on the day of the sale. You can instead choose one voucher per payout or per transaction.
- I have switched from Klarna to Kustom. Do I need to redo anything?
- No. You connect Kustom as a separate source with its own keys. The accounts can be copied from the Klarna source if you want.
- How is a partial return booked?
- As a reversal of that part of the sale in the settlement where Kustom deducted the amount.
- Where does Diffa get the data from?
- From Kustom's settlement and order management APIs, with keys you create in Kustom's portal.
