Local Invoice-to-Ledger

Turn invoice photos into proper double-entry bookkeeping entries locally

Problem

Small merchants and indie developers with bookkeeping needs find it painful to enter invoices, determine deduction rules, and link source documents when using tools like beancount. Someone already built a local tool with AI integration, proving the need is real and locally solvable, but generic tools are still not foolproof and non-accountants struggle to start.

Solution

A local desktop app: users drag in invoice images or PDFs and issue a natural-language instruction. AI extracts fields, opens the right accounts, applies deduction rules, archives the original, and generates standard double-entry journal entries, all validated locally for debit-credit balance.

Users

Small merchants, freelancers, and indie developers using beancount or similar tools for business bookkeeping

MVP

Drag-and-drop invoice images/PDFs; call a local or bring-your-own-key model for extraction; auto-generate beancount journal entries; built-in deduction rule checks (personal title, ordinary invoices, etc.); archive originals and link them for click-through preview

Revenue

One-time desktop license plus a subscription for ongoing rule updates; annual enterprise tier for multi-books and audit exports

Why now

Double-entry tools have long been developer-oriented, but AI can now reliably handle invoice extraction and rule application, lowering the barrier for non-accountants; local-first fits financial data privacy, and an indie dev can ship a usable version in weeks.
