Fortnox

Fortnox is the leading cloud-based ERP system for small and medium-sized businesses in Sweden and the Nordic region. It handles accounting, invoicing, inventory management and customer records in one platform — and is the standard choice for Nordic e-commerce merchants who need to connect their webshop to an accounting system. With Junipeer’s Fortnox connector, you can automate the full order flow: orders from Shopify, WooCommerce, Magento, Centra and other platforms create invoices in Fortnox automatically with the correct sales account, VAT code and shipping address. Stock levels from Fortnox update your webshop in real time — Fortnox is the master. Payouts from Klarna, Adyen, Svea and Shopify Payments are matched automatically against invoices, and provider fees are booked as write-offs. Returns in your webshop create credit invoices in Fortnox linked to the original. The integration handles OSS VAT per EU country (sales accounts in the 3000-series mapped per country), historical orders via date range, and B2B customers with organisation/VAT numbers. Setup takes about 15 minutes — configuring account mapping, OSS and payment methods takes longer but is a one-time setup. **Guides:** [Fortnox integration guide](/guides/accounting/fortnox-integrations-guide) · [Book Shopify sales in Fortnox](/guides/accounting/shopify-bookkeeping-fortnox) · [OSS & VOEC VAT guide](/guides/accounting/voec-oss-vat-guide)

With the Fortnox connector, you can retrieve essential business data including articles, stock levels, customer information, and orders from your Fortnox system. You can also store critical transactional data back to Fortnox, including new orders, payout information, invoices, refunds, customer updates, and article data. This bidirectional sync ensures your Fortnox ERP stays updated with real-time business information from all connected systems.
