* feat(mcp): book on custom accounts via account_override; fix kontoplan settings link gnubok_categorize_transaction only spoke a 19-category enum mapping to 21 hardcoded BAS accounts, so company-custom accounts (e.g. VMB) were unreachable from the agent surface even when active in the chart. - add account_override to gnubok_categorize_transaction with v1 REST semantics via a shared helper (lib/bookkeeping/account-override.ts): business-side replacement, class-2 auto-VAT drop with the 2610-2649 moms-line exception, plus a same-account degenerate guard; validated at staging and re-validated at commit - align the gnubok_create_voucher staging gate with the engine's seeding semantics: BAS 2026 accounts merely absent from the chart pass (the engine backfills them at commit) and the preview lists will_activate_accounts with BAS-name fallback; non-BAS unknown and inactive accounts still rejected - stop suggest_categories silently dropping mapping rules whose account is outside the fixed category maps; they surface with the rule's own account and an explanatory match_reason - correct the create_account next-step hint (categorize could never use the new account before; now true via account_override) - point the settings "Kontoplan (BAS)" link at /chart-of-accounts and redirect the orphaned /bookkeeping?tab=accounts URL (tab removed in #850; the deep link never worked after the #854 merge collision) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mcp): address review findings on account_override - commit executor rejects a present-but-malformed stored account_override loudly instead of degrading to the category default (CodeRabbit major; the approver approved a preview showing the override account); with commitPendingOperation regression tests - accountToCategory returns null for unknown income accounts so custom income accounts get the same diagnostic as expenses (CodeRabbit minor), with income + reason-accumulation tests (CodeRabbit nit) - pin the class-2 VAT-drop balance invariant with a test through buildTransactionEntryLines (Swedish compliance review: gross booking, never an unbalanced net + missing VAT leg) - account_override description asks the agent to state the actual affärshändelse in notes when overriding (BFL 5 kap description concern) - eventBus.clear() in the two new test suites (CodeRabbit minor) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mcp): never guess a moms leg onto an account_override without explicit VAT intent Round-2 Swedish compliance finding: the class-2 VAT drop did not cover margin-scheme (VMB) accounts in class 3/4, which are the override's flagship use case, so a forgotten vat_treatment attached the category default standard_25 and booked an ingående-moms deduction on a transaction where input VAT is not deductible (ML 2023:200). applyAccountOverride now takes explicit VAT intent (vat_treatment or vat_amount present) and books GROSS with no auto-VAT line without it: forgetting the flag under-deducts (lawful), never over-deducts. Both call sites (MCP staging preview, commit core) derive the flag the same way; the tool description states the enforced behavior. Deliberate divergence from v1 REST recorded in DECISIONS.md.

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.
