* feat(bookkeeping): cascade opening-balance corrections to later years Fortnox/SIE migrations book one IB verifikat per imported year, so correcting one year's ingaende balans left every later year's linked IB carrying the stale figures (support case: a 2019 IB fixed in Fortnox after export never reached Accounted, skewing all subsequent saldon). - POST /api/import/opening-balance/correct accepts cascade: true and applies the correction's per-account delta to each subsequent year's IB via storno + rebook + relink (lib/import/opening-balance/cascade.ts). Locked/closed/lock-dated/bokslut years are skipped and reported, never forced; a failed year is compensated and the cascade continues. - CorrectOpeningBalanceDialog offers the cascade as a default-checked checkbox when later years have their own IB verifikat, and when the current year is blocked it points at the earliest open year's IB verifikat instead of dead-ending.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012Jn6sxPE3zMfpM4CQ24jGY * feat(bookkeeping): Fortnox-style inline IB correction without storno Founder decision 2026-08-31: IB edits in open unlocked years should feel like Fortnox (change the number, no extra verifikat) instead of always producing a storno + rebook pair in serie A. - Migration 20260831150000 redefines correct_entry_lines_inline to admit source_type 'opening_balance' with three IB guards: only the period's current linked IB, no posted bokslut on the period, and replacement lines restricted to balance-sheet accounts (class 1-2). The entry id never changes, so fiscal_periods.opening_balance_entry_id stays valid and every report reads the corrected lines automatically. Storno, year_end and vat_settlement stay excluded; locked/closed/lock-dated periods are still refused (BFL 5 kap 5 par: storno is the only track there). - New POST /api/import/opening-balance/correct-inline: diff-based strike and replace inside the same IB verifikat, same OB_* pre-flight codes as the storno route, RPC rule violations surfaced verbatim as 409 OB_INLINE_REFUSED. With cascade: true the per-account delta is appended as labelled IB-rattelse lines inside each later open year's own IB verifikat (cascade mode 'inline'): a multi-year correction with zero new verifikat. - CorrectOpeningBalanceDialog computes the row diff (untouched lines keep ids, descriptions and dimensions) and posts to the inline route; copy updated (no storno language), toast reports inline updates. - In-app agent guidance (shared-rules) updated to describe the inline flow and the cascade checkbox. - Tests: pg-real suite for the redefined RPC (IB accept, linked-IB guard, bokslut guard, P&L guard, structural types still refused, non-IB unaffected), route tests, cascade inline-mode unit tests. The storno-based /correct route and engine paths are untouched: they remain for the import replace flow and API compatibility.

Reference Bokföringslagen generically instead. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012Jn6sxPE3zMfpM4CQ24jGY * fix(bookkeeping): derive inline cascade delta from the rattelse log Swedish-review finding on PR #2076: the cascade delta was computed from a route-side line snapshot read before the RPC, which a concurrent edit could theoretically desync from what the RPC actually committed. The delta now comes from the RPC's own journal_entry_rattelse_log row (struck_lines/added_lines snapshotted inside the RPC transaction), so the cascade always matches the committed base correction. Also softened the blocked-year guidance copy (declared-status is an assumption, not a verified fact). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012Jn6sxPE3zMfpM4CQ24jGY * fix(bookkeeping): visible cascade failure + dimensions-aware no-op check CodeRabbit round-2 findings on PR #2076: - A cascade that failed to run (log fetch error, unexpected throw) was returned as an empty successful summary, so the dialog reported nothing wrong while later years stayed unverified. Both routes now mark it failed: true and the dialog tells the user to check later years' opening balances. - The RPC's no-op guard compared account/amount/description only, so a dimensions-only rattelse raised 'Rattelsen andrar ingenting'. The comparison keys now include canonical dimensions jsonb text (fixed in the unmerged 20260831150000 migration).

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.
