Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag). Double-entry bookkeeping that complies with Swedish accounting law, built to be operated by you or by your AI agent.

Use Accounted · Self-host · Documentation · Contribute

Compliant by construction. Accounted implements double-entry bookkeeping under Swedish accounting law (Bokföringslagen). Voucher immutability, sequential voucher numbering, period locks, and 7-year document retention are enforced by database triggers, not by convention. See the architecture guide for the engine, enforcement, and audited correction paths.

Agent-native. The full bookkeeping engine is exposed as 150+ MCP (Model Context Protocol) tools with scoped API keys or OAuth, so an AI agent can do the books in Accounted: categorize transactions, draft vouchers, reconcile periods, and prepare declarations. Posting is staged for human approval, so the agent proposes and you decide.

Yours to run. AGPL-3.0 licensed and fully self-hostable with Docker and Supabase. Use the hosted version at app.accounted.se or run your own.

git clone https://github.com/erp-mafia/accounted.git
cd accounted
./docker/setup.sh       # Prompts for Supabase credentials, generates .env
docker compose up -d

You need a Supabase project and must apply the database migrations before first use. See docs/SELF-HOSTING.md for the full step-by-step guide, including Supabase setup, auth configuration, optional features (AI, email, push notifications), and troubleshooting. To run everything on Swedish infrastructure (your own Supabase stack, Swedish hosting, AI on Swedish GPUs), see docs/SOVEREIGN.md.

Prerequisites: Node.js 20 or newer (CI runs Node 20; the Docker image ships Node 22), a Supabase project.

npm install
npm run dev       # Start dev server (auto-generates extension registry)
npm test          # Run tests
npm run build     # Production build
npm run lint      # ESLint

See contributing guide for the full development workflow.

• Framework: Next.js 16 (App Router), React 19, TypeScript (strict)
• Database: Supabase (PostgreSQL + Row Level Security + email/password auth + TOTP MFA)
