* feat(bokslut): kontantmetoden year-end cut-off for fordringar and skulder Under kontantmetoden nothing reaches 1510/2440 during the year, but BFL 5 kap 2 § still requires fordringar och skulder to be booked at rakenskapsarets utgang. That conversion did not exist: the AR/AP tie-outs were permanently unreconciled by construction for all cash companies, and the balance sheet omitted every open invoice. Adds lib/core/bookkeeping/kontantmetod-cutoff.ts: Fordringar: Debit 1510 / Credit 30xx / Credit 2618|2628|2638 Skulder: Debit 4-6xxx / Debit 2648 / Credit 2440 Moms goes to the VILANDE accounts, never 2611/2641. Under bokslutsmetoden moms is reported at payment, and the vilande accounts are deliberately absent from ACCOUNT_RUTA / ACCOUNT_TO_BOX, so parking it there keeps it out of the momsdeklaration until the invoice is actually paid. Booking it to 2641 would claim the deduction a period early. Two aggregate verifikat, each reversed on day 1 of the next period, and no invoices.journal_entry_id link: the payment flows route on that link, so per-invoice linking would send every new-year payment down the accrual clearing path against a receivable the vandning already removed. Leaving it unset means a new-year payment still books the normal kontantmetoden cash entry at the real payment date. Outstanding is computed from payment DATES, not remaining_amount: an invoice settled in January was still a fordran on 31 December, and reading remaining_amount would shrink the cut-off every day the bokslut is delayed. Surfaced as a bokslut wizard reminder (warning, not a blocker: promoting it would newly block every cash company mid-bokslut, which is a separate call). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(bokslut): address compliance review on the kontantmetoden cut-off Three findings from the Swedish compliance review, all real: 1. BFL 5 kap 6-7 § traceability. The aggregate verifikat collected invoice references but never wrote them, so an examiner could not trace the 1510/2440 posting back to the affarshandelser behind it. Invoice numbers now go into the entry `notes` via buildCutoffNote(), truncated past 50 so the note stays a pointer to the reskontra rather than a copy of it. 2. Non-atomic posting. The cut-off and its vandning were two sequential creates with no rollback: if the reversal threw, 1510/2440 stayed permanently inflated and every new-year payment would double-book, which is exactly what the module docstring warns about. postKontantmetodCutoff now asserts the target period exists, is open, and contains the reversal date BEFORE posting anything, so the common failures refuse without writing. If a reversal still fails after its cut-off committed, the cut-off is stornoed through reverseEntry() (BFL 5 kap 5 §: never edit or delete a posted entry) and the original error is rethrown. 3. Silent vat_treatment default. Missing vat_treatment fell back to 25 %, which would route a 12/6/undantagen invoice to the wrong vilande account AND the wrong revenue account. Such rows are now collected into CutoffCollection.unknownVatTreatment, excluded from the cut-off, refused by the posting step, and surfaced as their own wizard reminder. Adds 11 cases for postKontantmetodCutoff, which had none: every refusal path asserts nothing was posted, and the storno-compensation path is covered in both the happy and the storno-also-failed direction. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(bokslut): never split a reverse charge across the cut-off Second compliance round. Verified the three data-dependent findings against production before changing anything; two needed no change, one is hardened: - Credit notes are NOT silently dropped: all 22 credit notes on prod carry document_type='invoice', so they are inside the collected set exactly as the comment claims. The filter only excludes proforma and delivery_note. - Vilande account numbers verified against the BAS 2026 chart in lib/bookkeeping/bas-data: 2618/2628/2638 utgaende, 2648 ingaende. The suggested 2617/2627/2637 do not exist. - Reverse charge: all 123 RC supplier invoices on prod carry vat_amount = 0, so no RC moms could reach 2648 today. That was an implicit data invariant, not an enforced one. CutoffPayable now carries reverseCharge and forces the cut-off moms to 0 for those rows, so a stray amount can never post a one-sided reverse charge into the single vilande bucket. The self-assessed output/input pair stays with the payment entry, after the vandning. Also names the reskontra as the underlag in a truncated aggregate note, so the verifikat points at its specification rather than implying the listed subset is the whole of it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(bokslut): surface stray moms on momsfri invoices instead of absorbing it Third compliance round, one legitimate new finding: moms on a treatment that cannot carry Swedish output moms (export, omvand betalningsskyldighet, undantagen) was folded into the revenue line with only a log.warn. That balances the verifikat while silently swallowing a real invoicing error, which is the netting the swedish-vat reference prohibits, and it was inconsistent with how the same module already treats a missing vat_treatment. Those rows now travel the same path as a missing treatment: collected into CutoffCollection.strayVatOnZeroRate, excluded from the cut-off, refused by the posting step, and surfaced as their own wizard reminder. buildCutoffLines keeps its balancing fallback for the case where such a row reaches it directly: it is now a last resort rather than the normal path, and it must still never invent a moms account nor unbalance the verifikat.

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.
