* fix(payments): refuse to book a bank row that unlinked vouchers already explain A bank feed can deliver several affarshandelser as one row (a Bankgirot daily aggregate: two customers' invoices, one "BGGIRERING" row with no payer). When each invoice was already marked paid by hand, nothing on the account equals the row, the 1:1 duplicate check passes, and "Dela betalning" books the money a second time against whatever open invoices the user picks (the next period's identical ones, in the reported case). - lib/reconciliation/covering-set.ts: exact ore subset sum over a capped candidate list, smallest set first, closest in date second. - detectExplainingVoucherSet(+ForTransaction): the vouchers whose bank legs on the row's settlement account, in the row's direction, within 7 days, add up exactly to the row; linked through any of the three anchors drops a voucher, a payment row without a bank transaction keeps it. - POST match-batch refuses with BATCH_TX_POSSIBLE_DUPLICATE and returns the set; force=true must echo expected_journal_entry_ids (same binding as the single door). Fails open on a detection error. - GET duplicate-payment-check returns candidate_set next to candidate. - MatchAllocationDialog: pre-flight panel with the vouchers, one click links the row to them through the existing 1:1 or 1:N bank link (no new voucher), "Bokfor anda" acknowledges the set; confirm is disabled until then. Invoices dated after the bank row get a hint badge. - Mark-paid guard: aggregate sweep (row = this invoice + an exact subset of other open invoices, 7 days, kronor) when the name sweeps found nothing; PaymentBookingDialog shows the covered invoice numbers and points to the split under Transaktioner. Follow-ups: #2293 (1:N proposals in the auto-matcher), #2294 (MCP staging guard), #2299 (supplier-side text guard).

The sweep itself now fails open on odd client shapes (a single object for a list query) and on errors: an advisory guard must never block "Markera som betald".

A PostgREST failure resolves with { data: null, error } instead of throwing, so the set detector read a failed link lookup as "no links" and a failed cash-account lookup as "scan every 19xx account"; both now return null (the booking RPC keeps the last word). The aggregate sweep never needed a customer name (a Bankgirot row names nobody), so a nameless invoice goes straight to it instead of skipping the guard. The already-booked panel is announced as a live region, and the "also covers" string is plural-aware.

Accounted
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.
Website · Hosted app · Documentation
Why Accounted?
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. Corrections are made the legal way, with reversal entries (storno), never by editing history. See ARCHITECTURE.md for how.
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.gnubok.se or run your own.

Self-Hosting
git clone https://github.com/erp-mafia/accounted.git
cd accounted
./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.
Development Setup
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.md for the full development workflow.
Tech Stack
- Framework: Next.js 16 (App Router), React 19, TypeScript (strict)
- Database: Supabase (PostgreSQL + Row Level Security + email/password auth + TOTP MFA)
