• Orders and refunds are pulled from Shopify via API/webhooks and transformed into Fortnox documents such as invoices, cash invoices, voucher rows, or credit invoices, depending on the configured posting model.
• Customers are mapped by a stable identifier (email and/or Shopify customer ID) to Fortnox customer records, with deduplication rules to prevent duplicate partners.
• Product and variant references (SKU, title, and tax class) are mapped to Fortnox article numbers; missing articles can be created automatically or flagged for review.
• VAT rates, shipping, discounts, gift cards, and payment fees are split into separate accounting rows and mapped to Fortnox accounts based on country, tax rules, and payment method metadata.
• Payment status and settlement data from Shopify Payments or external PSPs are routed into Fortnox as separate postings when required, keeping revenue and fees traceable.
• Sync jobs run as delta updates, logging each processed order number, retries on transient API errors, and storing payloads for reconciliation and audit trails.

Why choose scandiweb to handle Shopify integration for you?
How do you integrate Shopify with Fortnox for automatic invoicing and order posting?
We map Shopify order events to Fortnox invoices, payments, freight, discounts, and VAT, then automate document creation through the Fortnox API. You get consistent posting rules that match how your store actually sells.
Which Shopify order data fields sync to Fortnox in a Shopify Fortnox integration?
Typically, products, customers, addresses, tax rates, shipping, discounts, payment methods, and order statuses can be synced. We confirm the exact mapping during setup to avoid surprises in bookkeeping.
Can a Shopify Fortnox integration sync inventory levels and prevent overselling?
Yes, inventory can sync between Shopify and Fortnox based on your chosen source of truth and update frequency. This reduces stock drift when you sell across multiple channels or locations.
Does Shopify Fortnox integration support Swedish VAT, EU VAT, and multiple currencies?
It can, but it depends on how VAT logic is configured in Shopify and how Fortnox is set up for accounts and tax codes. We align tax mapping so reports in Fortnox match your VAT requirements.
How long does it take to set up a Shopify Fortnox integration, and what access is needed?
Most setups take days to a few weeks, depending on tax rules, product data quality, and edge cases like refunds. You’ll need Shopify admin access and a Fortnox integration user with API permissions.
