What it solves

Accounted is an open-source accounting software designed for Swedish sole traders and limited companies. It solves the problem of maintaining legal compliance with Swedish accounting law (Bokföringslagen) while providing a modern, agent-native interface that allows AI to assist with bookkeeping tasks.

How it works

The system implements a strict double-entry bookkeeping engine where legal requirements—such as voucher immutability and sequential numbering—are enforced via database triggers. It exposes its entire bookkeeping engine as over 150 tools via the Model Context Protocol (MCP), allowing AI agents (like Claude or ChatGPT) to categorize transactions and draft vouchers. To ensure accuracy, the AI proposes changes which are then staged for human approval before being committed.

Who it’s for

It is built for Swedish business owners (sole traders and limited companies) who want a compliant, self-hostable accounting solution that can be operated by either a human or an AI agent.

Highlights

• Agent-Native Design: Integrates with AI agents via MCP, offering specialized workflow skills for bookkeeping, VAT, and year-end tasks.
• Legal Enforcement: Uses database triggers to ensure voucher immutability and 7-year document retention per Swedish law.
• Comprehensive Financial Tools: Includes invoicing, PSD2 bank reconciliation, VAT declarations (SKV 4700), and payroll management.
• Swedish Standards Support: Supports BAS 2026 chart of accounts, SIE import/export, and Peppol e-invoicing.
• Self-Hostable: Can be deployed using Docker and Supabase for full data sovereignty.
