Accounting that runs itself — with Fortnox
As an official Fortnox partner, Storeborn makes it easy to connect your online store with your accounting system. Through a secure connection, your orders, invoices, customers and stock levels sync automatically — in real time.
Official and secure integration via the Fortnox API. Get started instantly without any hassle.
Skip the double work and focus on growing your business
Manually entering sales data takes up valuable time, and mistakes are easily made. Our Fortnox integration handles all the paperwork in the background. By eliminating manual data entry, you can focus your energy on running and growing your store.
Save hours every week
Forget about manually copying order numbers, customer details and amounts. Everything flows automatically – from the moment a customer clicks "buy" in your checkout to a fully booked invoice in Fortnox.
Zero manual errors
Amounts, VAT and payment methods are accurately matched against your chart of accounts. Your bookkeeping remains flawless, keeping both you and your accountant happy.
Two-way real-time sync
Orders are sent to Fortnox as soon as a purchase is made. At the same time, stock levels are updated in your online store, ensuring you always display the correct inventory to your customers.
Fully built-in – no middlemen
You don't need to pay for expensive third-party integrations or extra software licenses. This solution is built and maintained directly by us at Storeborn, fully optimized for the latest Fortnox API.
Together, you get something neither system can do on its own: your store and your accounting become one flow – in real time, without a single manual step in between.
Built for businesses of every size
Whether you've just shipped your first orders or you handle thousands a month, your store and your accounting become a single seamless flow – the integration grows with you.
Small businesses & startups
Get started without a finance department. The integration handles your bookkeeping from the very first order, so you can spend your time growing instead of on admin.
Small & mid-sized retailers
As order volume climbs, manual handling becomes unsustainable. The automation scales with you – without hiring extra people purely for reconciliation and bookkeeping.
Enterprise & larger operators
High volumes, multiple payment methods and complex VAT flows are handled automatically and accurately, with capacity and tenant isolation built for scale.
A completely frictionless order flow
Forget about exporting files and dealing with messy CSV lists. When something happens in your online store, Fortnox updates instantly – and vice versa. The systems communicate 24/7 without you having to lift a finger.
Orders
Sent to Fortnox immediately upon purchase – complete with line items, shipping costs and any applied discounts.
Customers
Automatically matched or created based on email or corporate identity number. Addresses and VAT status are, of course, included.
Products
Your products are securely matched against your Fortnox product registry using the product's SKU / article number.
Invoices
Created automatically at the exact stage you prefer – for example, when the order is received, processing or shipped.
Inventory
The synchronization ensures your stock levels always match in your store, even if you sell through other channels or log sales directly in Fortnox.
Payments
Incoming payments are booked to the correct account based on how the customer paid (credit card, invoice, local payment methods etc.).
From checkout to booked in seconds
When a customer places an order, it is sent directly to Fortnox. You decide in your settings whether the bookkeeping should occur immediately upon payment, when you pack the item, or when it is shipped.
Invoices that take care of themselves
We create the invoice in Fortnox and post it to the correct account. Your accountant gets a complete, accurate foundation every month – without you having to hunt down missing receipts or vouchers.
Stock levels update automatically in your store
A shared inventory across both systems
You choose which system controls your stock levels – Fortnox or your online store. By matching product SKUs, the integration ensures you never accidentally sell products that are out of stock.
