Fortnox on Oliver POS
Fortnox receives Oliver POS counter sales through the WooCommerce + Fortnox connector — Sweden's dominant SMB accounting platform with in-store revenue unified to one ledger.
How Fortnox works with Oliver POS for WooCommerce
Fortnox is the leading Swedish SMB cloud accounting and business platform, used by hundreds of thousands of businesses. The WooCommerce + Fortnox connector (WeSync, Cloudshop, and similar) posts orders as Fortnox invoices and customers as Fortnox kunder. Oliver POS writes register sales into WooCommerce, Fortnox picks them up — moms (VAT) returns and SIE exports reflect unified revenue.
What Fortnox pulls from WooCommerce
The WeSync for Fortnox connector (and Cloudshop's equivalent) syncs WooCommerce orders into Fortnox as invoices (fakturor), customers as Fortnox kunder, products as Fortnox artiklar, and refunds as credit invoices. Fortnox then handles Swedish moms codes, SIE export for the Skatteverket, and the standard Swedish accountant workflow.
Oliver POS sales become WooCommerce orders; the Fortnox connector treats them identically to online orders.
Why in-store sales matter on the Fortnox ledger
Swedish SMB accounting practices revolve around Fortnox the way the UK revolves around Xero/QuickBooks. Accountants expect everything on the Fortnox ledger, the SIE export at year-end has to balance, and Skatteverket submissions pull from Fortnox. Oliver POS on WooCommerce keeps the ledger whole.
How the WooCommerce + Oliver + Fortnox sync works
Cashier rings the sale on Oliver POS, captures the customer, tenders. Oliver writes a WooCommerce order with moms applied. The Fortnox connector creates or matches a Fortnox kund, posts an invoice with line items and moms codes, and records the payment against the configured Fortnox bank account.
Best fit for retailers who…
Fortnox on Oliver POS suits Swedish SMB retailers across the board — boutiques, specialty food, indie shops, and small chains. The combination keeps the existing Fortnox-accountant relationship intact while adding a modern WooCommerce-friendly register.

Common questions about Fortnox on Oliver POS
Does Fortnox produce a clean SIE export with Oliver POS sales included?
Yes. The SIE export pulls from the unified Fortnox ledger. Oliver POS sales become WooCommerce orders, the connector posts them as Fortnox invoices with the right moms codes, and the SIE export covers them.
Will Fortnox's automatic moms-deklaration include in-store Oliver POS revenue?
Yes. Fortnox calculates the moms-deklaration from the invoices in the ledger. Once Oliver POS sales reach Fortnox through the WooCommerce connector, they're included automatically.
Does Oliver POS have a partnership with Fortnox?
No. Oliver doesn't partner with Fortnox or any other accounting platform. We support Fortnox because its WooCommerce connector already pulls orders, refunds, taxes, and customers from your store — and Oliver writes every in-store sale into WooCommerce as a standard order, so the same connector picks it up automatically. Your accounting subscription, your ledger, and your contract stay between you and Fortnox.
Does Oliver charge extra to use Fortnox?
No. You pay Fortnox's standard published pricing directly to Fortnox. Oliver doesn't take a markup, doesn't insert itself into the data flow, and doesn't charge a per-transaction or per-journal-entry fee on top.
Do register sales from Oliver POS reach Fortnox?
Yes. Every Oliver POS sale is written to WooCommerce as a standard order with the customer, line items, taxes, and payment method attached. The Fortnox WooCommerce connector treats that order the same way it treats an online order: it posts the same invoice, journal entry, or sales receipt, with the same tax splits and the same customer record. There's no separate "POS sync" to configure.
How fast does a register sale reach Fortnox?
It depends on the Fortnox connector's sync mode. Connectors that push per-order (most Fortnox integrations support this) post the invoice or sales receipt into Fortnox within seconds of the cashier closing the sale. Connectors set to a daily summary post a single end-of-day journal entry with per-tax, per-payment-method, and per-outlet splits. Either way, no manual entry is required.
Will my in-store and online sales reconcile against one set of books in Fortnox?
Yes. Oliver POS writes register sales into the same WooCommerce store that powers your online checkout, so by the time orders reach the Fortnox WooCommerce connector they're already a unified order stream. Fortnox sees one revenue feed, one tax-liability total, and one customer ledger — no manual reconciliation between an online and an in-store set of books.
