* fix(bokslut): kontantmetod cut-off treats the ROT/RUT share as settled on 1513 Root cause: collectKontantmetodCutoff compared invoice_payments against the gross invoice total and never read deduction_total. Under fakturamodellen the customer owes total minus the skattereduktion; the deduction is a fordran on Skatteverket carried on 1513 by the payment voucher (Dr 1930 customer share / Dr 1513 deduction / Cr 30xx / Cr 26xx in full), and every settlement path records the customer share as the payment row amount. A fully paid ROT/RUT invoice therefore showed exactly deduction_total as outstanding, and the year-end cut-off booked a phantom Dr 1510 / Cr 30xx / Cr 2618 on top of a sale whose revenue and moms were already fully recognised: revenue overstated and vilande moms invented. Fix: the customer's outstanding is total - deduction_total - paid (the deduction follows the sign of the total, since credit notes store it as a positive magnitude), floored at zero on the invoice's own side for over-collection noise, mirroring the invoices_remaining_amount_guard formula. The moms carried into the cut-off is scaled by the customer share, not the gross total, so an unpaid ROT/RUT invoice reports its whole moms in the final period and a part-paid one the matching fraction. Invoices without a deduction take the unchanged gross path. The readiness gate, the pending-operation executor and the MCP tool all consume this collector, so they inherit the fix. The Skatteverket share itself (an unpaid ROT/RUT invoice's 1513 fordran at year end) is not part of the cut-off and stays a separate change, as is the 1513 point already deferred on the currency revaluation. Fixes #2248 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015qgLgdt4mLmha1ZLFMwq1u * refactor(invoices): one definition of the customer share of an invoice The customer share of an invoice (total minus the ROT/RUT deduction, and what remains of it after payments) was re-derived by hand at three TypeScript sites plus the SQL guard invoices_remaining_amount_guard, and the kontantmetod cut-off's copy had drifted to the gross total (#2248). Fixing the cut-off's arithmetic alone would leave the next copy free to drift the same way. lib/invoices/customer-share.ts now holds the definition: invoiceCustomerShare(invoice) returns total minus sign(total) times deduction_total (the deduction is stored as a positive magnitude, also on credit notes), and invoiceCustomerOutstanding(invoice, paid) returns the signed residual after payments. The module comment names the SQL twin (migration 20260817191708) so the two stay in lockstep; the SQL is untouched. Call sites moved onto the helper with byte-identical behaviour: kontantmetod-cutoff.ts (keeps its as-of payment sum, the sign-aware zero floor for ROT/RUT rows and the moms scaling), rot-rut-file.ts (the customer-share-paid test) and payment-sync.ts (the storno path, which still floors with Math.max(0, ...) because it persists the column). Plain invoices get their total back exactly as stored, so their paths do not change by a bit. New unit tests cover plain, ROT/RUT, credit-note sign, null deduction and the lockstep with the guard's formula.

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)
