What problem does the integration solve?
Used separately, operations and finance often run in silos. Together, Comreact and Fortnox provide a reliable flow from order and warehouse events to accounting actions.
Eliminates duplicate entry of order and billing data.
Reduces mistakes between warehouse output and customer invoices.
Shortens lead time from shipment to invoicing and cash collection.
Creates a clearer operating picture for both logistics and finance.
How does the integration work?
The integration transfers key business data in both directions with mapping and validation in place.
Comreact (Warehouse, orders, picking records for 3PL accounting)
Fortnox (Accounting, invoicing, financial follow-up)
Data flow checklist

Who benefits the most?
The integration is especially valuable for teams with frequent order turnover and recurring billing.
3PL operators and fulfillment providers
For businesses that invoice storage, picks, and extra service lines per customer.
Growth-stage companies (200â10,000 orders/month)
For teams that outgrow spreadsheets and want reliable process control without enterprise complexity.
What happens after integration?
Setup is straightforward, but we recommend a short onboarding to ensure chart of accounts, articles, and billing logic are mapped correctly.
1
Kickoff and scope: confirm data fields, entities, and billing rules.
2
Configuration: map articles, accounts, and customer structures.
3
Validation: run test data and verify accounting output before go-live.
4
Go-live and follow-up: monitor first cycles with joint support.
