* fix(rot-rut): payment-side booking, reminders and claim completeness Follow-ups from the 2026-08-17 ROT/RUT audit (dev_docs/rot_rut_audit_2026_08_17.md). Payment side (fakturamodellen: the customer pays total minus avdraget, the rest is a 1513 receivable on Skatteverket): - createInvoicePaymentJournalEntry without an explicit paymentAmount used to book invoice.total on 1930/1510. Every no-lines mark-paid path (MCP mark_invoice_as_paid, v1 API, no-body dashboard route, Stripe) settles the outstanding amount, so on a ROT/RUT invoice 1510 went negative by the deduction and 1930 was overstated; same defect for any previously part-paid invoice. It now books the outstanding amount (remaining_amount, else total minus paid_amount); a fully outstanding invoice keeps the total_sek path. - proposePaymentLines had no deduction awareness: the payment dialog pre-filled D1930 total / K1510 total, which the settlement plan rejected as an overpayment, so a ROT/RUT invoice could not be marked paid from the UI. Accrual: bank + 1510 carry total minus avdrag; cash method: bank gets the customer share, 1513 the avdrag, revenue + moms in full. Foreign invoices without a booking rate refuse (1513 is a kronor receivable). Dialog passes deduction_total. - Reminders and dröjsmålsränta were computed on invoice.total: a privatperson was dunned for the Skatteverket share and charged interest on it. New reminderPrincipal() = the invoice's "Att betala" (öre-rounded total minus avdrag) drives the processor's interest base and all three templates. Claim completeness (HUSFL 2009:194: art av arbete + antal arbetstimmar): - work_type and labor_hours were optional at creation but hard blockers at begäran-file time, when the invoice is numbered, booked and paid and cannot be edited. validateDeductionLines() now requires a same-kind arbetstyp and hours > 0 (schablontjänster exempt) on every deduction line; wired into validateInvoice, CreateInvoiceItemSchema (field-level issues) and the editor schema with inline errors under the ROT/RUT strip. Fixed the labor_hours register (valueAsNumber overrode setValueAs: an emptied field became NaN and failed validation with no visible error). The Underlag card now shows whenever any row is flagged, matching the payload/server predicate. Yearly ceilings: - COMBINED_MAX 75 000 kr: ROT + RUT share one ceiling per person (ROT capped at 50 000 inside it). deductionCapWarnings() carries the per-kind and the combined check plus optional prior-year totals; validateInvoice forwards them; the editor uses the same helper and fetches what the customer has already been granted in the invoice year (per customer, warning only). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(rot-rut): treat remaining_amount left at DEFAULT 0 as unmaintained when booking a payment Rows written by paths that bypass buildInvoiceWriteData (imports, sandbox seed, legacy migrations) carry remaining_amount = 0 while unpaid; prod has ~330 such open invoices. Booking 0 would have failed the engine's positive- amount rule, so the outstanding helper derives total - paid - deduction when the stored value is not positive. Test. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(rot-rut): review follow-ups on #1652 - ROT/RUT completeness moves to the invoice-level schema (CreateInvoiceSchema / UpdateInvoiceSchema share one refine) so it only applies to real invoices and skips text rows; the editor gates its mirror on the document type via a ref. Tests moved accordingly (CodeRabbit). - Prior-year deduction lookup follows the PAYMENT year (paid_at, else invoice_date for open invoices), paginates via fetchAllRows, and clears the total on a failed request instead of leaving a stale one. - rot-rut-file derives its schablon flags from SCHABLON_WORK_TYPES so the validator and the generator cannot drift. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(rot-rut): pick the prior-year deductions client-side (phantom-columns ceiling) The runtime-built .or() filter counted as an unresolvable query expression for the no-phantom-columns guard. A customer has few deduction invoices, so fetch them all and select the payment year in code.

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.
