Expensify?
BUILD FIRST
- A non-sensitive or read-only version of the core experience
- A manual review step wherever correctness or trust matters
- A narrow companion tool that removes a real piece of work
LEAVE FOR LATER
- Regulated decisions, payments, or irreversible actions
- Claims of correctness, compliance, or uptime that the MVP cannot support
- Sensitive integrations until security, support, and auditability are ready
RESEARCH NOTES
What this tool actually does.
Expensify is an all-in-one expense management (spend management) platform for individuals and businesses. Users capture receipts via photo, email forward, or mobile app, and AI-powered SmartScan/Concierge extracts data, auto-categorizes expenses, checks company policy rules, and flags violations. Expenses are auto-assembled into expense reports that flow through submit, approval, and reimbursement (globally, in local currency), then sync to accounting systems. The product also offers corporate card reconciliation with bring-your-own-card support, its own corporate card with cash back, mileage tracking, budgets, financial reporting, bill pay, and invoicing. Native iOS/Android apps cover all functionality. It integrates with 45+ tools including QuickBooks, NetSuite, Sage Intacct, Xero, Workday, Gusto, Uber, and Lyft. Free for individual use; company plans start at $5 per member/month, offs
RESEARCHED BUILD PROMPT
Give this to your coding agent.
Build a self-hosted web app reproducing Expensify's core workflow: capture receipts (image upload or email forwarding), OCR them to extract merchant, date, amount, and currency, auto-categorize line items, validate them against configurable policy rules (per-diem limits, approval thresholds, non-reimbursable categories), auto-assemble approved expenses into periodic expense reports, run an approver review and reimbursement-status workflow, and export reports as CSV and as accounting journal entries (QuickBooks-style double-entry lines). User-facing requirements: role-based accounts (employee, approver, admin); receipt image/PDF upload with editable OCR results; manual mileage entry (rate x distance); report builder with submit, reject, and approve actions; policy-violation badges; spending dashboards; CSV/PDF export. Technical requirements: SQL database, blob storage for receipts, REST API, a background job queue for OCR/parsing, JWT or OAuth auth, and database-driven policy rules. Suggested stack: React frontend, Node.js or Python backend, PostgreSQL, Redis-backed queue, OCR via Tesseract or a hosted vision API. Do not copy Expensify's brand, logo, copy, or visual UI; design an original, distinct interface. Out of scope: corporate card issuance, real bank/card feeds, multi-currency FX settlement, payroll integrations, and native mobile apps (a responsive web UI suffices). Deliver a README covering setup (env vars, DB migrations, local OCR setup) and important limitations (OCR accuracy on faded or tilted receipts, no live card data, single-currency assumptions where noted).
