* fix(sie): selectable IB voucher series that never collides with the file's numbering The Ingående balanser voucher was hardcoded to series A and created before the file's vouchers, so it consumed the A series' next number and shifted every imported A voucher one number higher than in the source system (issue #1882). - IB voucher series is now selectable in the import wizard; the default is the first of M,O,P,Q,R,S,T,V,W,X,Y,Z not used by the file's #VER records (M matches the existing migration-adjustment series). - Plumbed end to end: wizard -> /api/import/sie/execute -> executeSIEImport, v1 REST options.openingBalanceSeries, MCP gnubok_import_sie opening_balance_series -> commitImportSie. - The wizard's 'Importera ingående balanser' toggle now defaults OFF when a posted IB voucher already exists inside the file's fiscal year, with a hint saying why. - Orphan-IB guard in executeSIEImport: replace_sie_import deletes only source_type='import' entries and clears the period's OB pointer, so a prior import's IB voucher survived every replace cycle and each re-import created another one (field report: five accumulated). The import now skips IB creation with a warning when a posted opening_balance entry already exists in the period. - MCP import_opening_balances default (false) vs web (true) documented as deliberate in the tool schema and DECISIONS.md. Fixes #1882 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(sie): harden IB series fix after skeptic review (relink orphan, exclude fallback series, type-check option) Skeptic findings on PR #1896, all four blocking items: - Orphan-IB guard now relinks a single surviving opening-balance voucher as the period's OB entry (permitted by the immutability trigger while the pointer is NULL): without it, reports showed IB 0, year-end's duplicate-IB blocker never armed, and the manual IB flow could double-book. It also diffs the survivor's lines against the file's IB and calls out stale amounts in the warning instead of keeping them silently; reverseEntry clears the pointer again for the storno-then-reimport path. - Series-less #VER records resolve to the transaction fallback series at import time, so the IB default picker now treats that series as used by the file (the same #1882 shift pattern through the fallback). The wizard recomputes its IB default with the effective transaction series once loaded. - openingBalanceSeries is type-checked on the web execute route, the MCP stage, and the staged-operation commit: a non-string falls back to the default instead of crashing mid-import after side effects. - The wizard's IB series select flags series used by the file and shows an attention line when the chosen series collides; the engine warns when an explicitly chosen series collides with the file's series (the choice is honored). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(sie): uppercase caller-chosen IB series before persisting Swedish accounting review on PR #1896: a lowercase series from v1 or MCP was persisted as-is, booking a case-distinct parallel series next to its uppercase sibling (BFL 5 kap requires one systematic series) and slipping past the file-collision warning. Normalize centrally in executeSIEImport, the single funnel for web, v1, and MCP.

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.
