What a Wix Stores order looks like in Fiken: sales, payments and refunds

By Kayabyte

Disclosure: Kayabyte makes Sales Bookkeeping Sync, an app for Wix sites, and this guide describes what it books. Everything below was checked against a Fiken demo company on 11 November 2026, using test data only.

The short answer: to bokføre a Wix order, the app books a paid Wix order as one sale in Fiken (kind “Annet salg”, other sale) with one line per product, shipping and fee, and a payment on your bank account. A refund becomes a second, negative sale plus a negative payment. A cancelled unpaid order is reversed. Totals, VAT and income match Wix to the øre.

A paid order

For an order with two products at 25 percent VAT and shipping, Fiken shows one sale named “Wix #” plus the order number. It has a line for each product and for shipping, each with net amount, VAT and the account and VAT code you mapped, and the buyer as the customer. The payment is registered on your bank account, and the sale shows as settled. Discounts are on the line (the description says “discount” with the amount) or a separate negative line for order-level coupons. A free line (price 0) is left out, because Fiken refuses lines without an amount. Quantity is written into the description, for example “3 x Shirt”, as Fiken sale lines have no quantity.

Customers: the app looks for an existing Fiken customer with the same email and creates one if none exists; you can switch to one shared customer for all store orders.

A refund

Fiken’s interface offers credit notes only for invoices that Fiken itself issued. Because the sale is not a Fiken invoice, the app books a refund as a negative sale with the same accounts and VAT codes as the original, named after the order and the refund, and then a negative payment on the bank account. Income, VAT and the receivable are reduced by exactly the refunded amount, and a partial refund followed by a refund of the rest nets to zero over the three documents. You will see a negative sale, not a credit-note document.

A cancelled unpaid order

If an order is cancelled before it is paid and the app has already booked it, the sale is deleted in Fiken with a reversing entry, so the books net to zero.

Draft mode

If you choose drafts in Settings, each order arrives as a draft in Fiken. You approve the draft in Fiken; it becomes a normal sale with the same number. In draft mode the app does not record the payment: you do that in Fiken after approval.

What can go wrong, and what you see

• Fiken is busy or offline: the app retries and a daily check catches anything missed.
• A VAT code does not fit the account: Fiken’s message is shown on the order in the Sync log; fix the mapping and press Retry.
• The books are locked for the date: orders paid on or before the lock date cannot be booked; you see that in Settings.
• A foreign currency order with Norwegian VAT: Fiken does not allow it; the Sync log explains.
• The bank account is inactive in Fiken: choose another in Settings.

Not included

Payment provider fees and payouts are not synced: the store does not share them. The app does not send invoices to customers and does not issue Fiken invoices.

FAQ

Where do I find the sale in Fiken? In the sales area of Fiken, among the other sales, named “Wix #” and the order number. The Sync log row links to it.

Why is my refund a negative sale? Fiken only credits invoices that Fiken issued. A negative sale with a negative payment gives the same effect on income, VAT and bank.

Will an order be booked twice? No. Each order is looked up by its number before it is created, and retries use the existing sale.

Can I change an order after it is booked? Changes to a booked order in Wix are not copied; refunds are. Fix other changes in Fiken.

What if I disconnect the app? Syncing stops; everything already in Fiken stays as it is.
