* docs(bookkeeping): audit + runbook for template-caused mis-bookings Two of the template defects fixed this week produced postings that SUCCEEDED and are still sitting in customers' huvudbocker: travel_hotel debited 5820 Hyrbilskostnader instead of 5830 Kost och logi (#1397), and the representation template deducted 25% input VAT on a 12% restaurang supply (#1396). Fixing a template only changes future postings. Follows the pattern already established by SETTLEMENT_ACCOUNT_REMEDIATION.md for the same class of problem: read-only detection, per-entry evidence review, staged storno with explicit approval, no automated bulk mutation. Deliberately excludes vehicle_parking (5614) and it_cloud_hosting (5421). Those named accounts that never existed in BAS, so account-backfill could not seed them and every booking failed. Nothing was posted, nothing to remediate. Detection is by account signature and is diagnostic only, because there is no provenance link from a posted entry back to the template that produced it: template_id lives on mapping_rules, not on journal entries. Both signatures have legitimate shapes (5820 IS correct for real car hire; representation at 25% IS lawful when the supplier charged 25%), so a row is a question and never a verdict. The classifier is verified against seeded probes rather than assumed: a hotel booked to 5820 with a hotel counterparty ranks high, a genuine car hire on 5820 falls to manual review, a 25% representation ranks high, and a correct 12% representation does not appear at all. Query confirmed to run against the real schema (the lock date lives on company_settings, not companies). The runbook records what BFL 5 kap 5 § actually requires: both tracks, that storno is the only one available once a period is locked or the bookkeeping has been relied upon, and that there is NO numeric materiality threshold in BFL. Materiality decides whether a historical correction is worth making, never whether a silent one is allowed. For the VAT defect it also flags that a filed momsdeklaration makes this an omprovning question, not just a ledger one.

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 100+ MCP (Model Context Protocol) tools with scoped API keys, 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.
