Fortnox

This server connects Claude to Fortnox, the Swedish accounting system, exposing the full API for managing invoices, customers, suppliers, and vouchers. You get operations for creating and bookkeeping invoices, approving supplier invoices, searching vouchers, and running analytics like cash flow forecasts and gross margin trends. It ships in two modes: remote mode where users authorize through a browser with no credential setup, and local mode where you run it with your own Fortnox app credentials. The tool set covers everything from basic CRUD on customers and accounts to business intelligence queries like order pipeline analysis and period comparisons. Reach for this when you need Claude to handle Swedish accounting workflows or answer financial questions by querying Fortnox directly.
