How to connect Wix Stores to Fiken (2026)

By Kayabyte

Disclosure: Kayabyte makes Sales Bookkeeping Sync, an app for Wix sites that this guide describes in one section. Facts about Fiken come from Fiken’s own pages and API documentation, linked below. Checked on 11 November 2026.

The short answer: Wix Stores has no built-in connection to Fiken (the Norwegian accounting system, regnskap), so paid orders do not reach your books on their own. You can book them by hand, connect the two with an automation tool, or use an app that sends each paid order to Fiken as a sale with the payment recorded. Whichever you use, the Fiken company needs its API module for anything that talks to Fiken automatically.

Before you start: set up Fiken for store sales

Decide these once, in Fiken:

• Sales account. Most Norwegian web shops book goods on 3000 (sales of goods, high VAT rate). Goods with other VAT treatment need their own account (see Norwegian VAT and Fiken VAT codes).
• Bank account for the payments. Payments from your payment provider arrive as payouts, later and minus fees. If you want payouts matched to the store’s payments, book the payments to a clearing account and let the payout clear it.
• VAT codes. Fiken uses codes such as high rate (25 percent), medium rate (15 percent, food), low rate (12 percent) and exempt (0 percent). Every line of an order needs a code that fits its sales account.
• API module. Fiken’s API is a paid add-on for the company, and Fiken says production use of its API on live data carries a fee. Check the company’s subscription and add-ons in Fiken, or ask Fiken, for the current price and for how to switch it on.

Option 1: book orders by hand

Fine for a few orders a week. For each paid order in Wix dashboard > Sales > Orders, create a sale in Fiken with the same lines, VAT and total, then register the payment against the bank account. For a refund, book a reversing sale and the payment out.

It gets slow and error-prone as orders grow; refunds and shipping VAT are the usual misses.

Option 2: an automation tool

Tools such as Albato can watch for new Wix orders and create Fiken documents; Albato lists Fiken among its connectors, with Wix triggers such as “Order updated” and Fiken actions such as “Create invoice”. Such a flow usually creates a Fiken invoice rather than a recorded sale, so check how it handles tax-inclusive prices, discounts, shipping, refunds, partial payments and orders paid later, and whether a failed run is visible to you. Each of those needs its own step in a no-code flow.

Option 3: an order sync app

Order sync apps from the Wix App Market send paid orders to Fiken automatically. What to check before you choose one:

• Sales and payments. The order should arrive as a sale with the payment registered, not as an open item.
• Refunds and cancellations. A refund should reduce income, VAT and the bank by the refunded amount; a cancelled unpaid order should be reversed.
• VAT. You should match each store tax rate to a Fiken VAT code, and tax-inclusive store prices should stay tax-inclusive.
• No duplicates. A retry after an error must not book the order twice.
• Errors you can see. An order that could not be booked should be listed with the reason and a way to retry.
• Earlier orders. Whether past orders can be imported, and from which date.

Sales Bookkeeping Sync

Sales Bookkeeping Sync (app page) is a Wix app made by Kayabyte for exactly this. Setup takes about ten minutes:

1. Install it from the Wix App Market and start the 14-day trial of a plan (Starter $6 a month for 100 orders, Growth $12 for 500, Business $24 for 2,500; about 17 percent less billed yearly).
2. In Apps > Sales Bookkeeping Sync > Connect, choose Connect to Fiken, sign in on Fiken’s own page, allow access and pick the company.
3. In Settings, choose the sales, shipping and bank accounts and match each VAT rate on your orders to a Fiken VAT code. Choose final sales or drafts, set a start date and save.
4. Place or wait for a paid order. Within about a minute the Sync log shows it with a link to the sale in Fiken.

It books each order as a sale (“Annet salg”) with the payment applied, refunds as negative sales with a refund payment, and cancelled unpaid orders as reversed sales. It does not sync payment provider fees or payouts, and foreign currency orders are booked only without Norwegian VAT. Fiken limits how many companies a new integration may serve until production status, so there can be a waitlist.

What gets booked is described in what a Wix order looks like in Fiken.

Check the first orders

Whatever you use, test with three orders: one plain order, one with shipping and a discount, and one refunded. In Fiken compare the total, the VAT amount and the bank balance with the Wix order. They should match to the øre.

FAQ

How do I get Wix orders into Fiken (bokføring of an online shop)? Book them by hand, use an automation tool, or use an order sync app that books each paid order as a sale with the payment registered. The sections above compare the three.

Does Wix connect to Fiken out of the box? No. Wix Stores has no built-in Fiken connection that we know of. Use an automation tool or an app.

Do I need Fiken’s API module? Yes, for any automatic connection. Companies without it appear when you connect but cannot be used.

Should orders become Fiken invoices or sales? A Wix order is already an order document with its own number. Booking it as a sale with the payment keeps one document per order and exact totals. Fiken-issued invoices are for invoicing customers from Fiken.

What about payment provider fees? The store does not share them with apps. Book them from your payout report or bank statement.

Can I try it on a test company? Yes. A Fiken demo company works: it is how we tested. The connection step lists every company you can reach.
