* fix(invoices): guard cash-method partial payments across every payment path A never-booked kontantmetoden invoice can only be settled by the generated cash entry (createInvoiceCashEntry / createSupplierInvoiceCashEntry), and that entry always books the FULL invoice: it takes no payment amount. Three payment surfaces still let partial payments through to it, corrupting books: - settleInvoicePayment dropped the fully-paid term entirely, so a partial payment (Stripe sync, mark-paid) booked the entire invoice: over-recognized revenue, over-declared output VAT, and a bank debit that did not match the money received. - The dashboard and agent match-transaction paths fell back to an accrual-style clearing entry against an EMPTY 1510: negative receivable, no revenue, no moms (ML 13 kap 8 § puts each installment's moms in its own receipt period). The comment claimed the credit "gets resolved on final payment", but the cash builder never touches 1510 and books the full total, so the final payment double-debited the bank instead. - The supplier routes had no full-settlement term at all, so a partial payment booked the full expense + input VAT. Fix: one shared predicate (cashPartialBlockReason in booking-mode.ts) rejects generated cash entries unless the payment settles the invoice in full from a fully unpaid state, wired into all six POST surfaces, the agent commit paths, and the three preview routes (so dialogs cannot propose a verifikat the POST refuses). New bilingual error codes INVOICE_PAID_CASH_PARTIAL_UNSUPPORTED / SI_CASH_PARTIAL_UNSUPPORTED. Invoices booked at issue are unaffected: their partial payments keep the normal 1510/2440 clearing path. The v1 match-invoice route already had this guard (VALIDATION_ERROR); its behavior is unchanged. Proper per-installment recognition (proportional revenue + moms per receipt) is the follow-up feature that would lift this restriction.

The substantive rule (bokslutsmetoden reports moms at payment, per installment, except at year-end) is unchanged and stated without a section cite until the current-law section is verified. Comments and cookbook prose only; no behavior change. Also fixes the two pre-existing occurrences.

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.
