Finance and accounting decision
Expensent
A competent developer can build a useful email-receipt forwarder (detection + one-click or rule-based forwarding) in a few weeks, but reproducing the full polished product (privacy pipeline, many accounting integrations, mobile scanner, and support/operations) is larger and operationally heavier than a simple DIY replacement.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Connect an inbox, detect invoices from metadata, surface matches in a review UI, and forward accepted receipts to an accountant or accounting tool (with optional auto-forward rules).
What it still won’t have
- Refined, privacy-first three-stage pipeline and its documented guarantees
- Polished inbox organization and mobile scanner experience
- Built-in connectors or direct integrations to many accounting platforms beyond email forwarding
- Priority support, account management, and turnkey historical 10-year inbox scan with UI
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal 'Expensent' replacement: use Node.js + Express backend, Postgres DB, Redis for jobs, React + Tailwind frontend, and worker processes. Core features in scope: OAuth connectors for Gmail and Outlook (and IMAP fallback), inbox metadata scanner (sender/subject/attachment name rules), body/attachment fetcher with optional OCR (Tesseract) or OpenAI/Text-extraction API for invoice detection, one-click forward via SMTP/SendGrid and configurable auto-forwarding rules, a review queue UI with search and basic reporting, and a historical inbox scan job. Out of scope: mobile camera scanning app, deep accounting API integrations (beyond sending emails or simple API calls), multi-tenant admin dashboard, and enterprise compliance. Provide error handling, retries, logging, background job tests, and end-to-end tests for the connector + forwarding flow.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
