Finance and accounting decision
FreeAgent
A single developer can build a useful invoicing/expenses/reports replacement, but replicating FreeAgent’s HMRC-recognised filing, payroll, mature bank integrations and UK-specific compliance/support is hard to fully reproduce—so building makes sense for a narrow workflow but not as a drop-in replacement for the full paid product.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Manage invoices, record expenses and receipts, import bank transactions, produce accounting reports and file VAT/MTD submissions to HMRC
What it still won’t have
- HMRC-recognised end-to-end MTD certification and filings
- Mature bank feed partnerships and one-click connections (Tyl, Stripe, GoCardless, PayPal)
- Built-in payroll with RTI filing to HMRC and pension calculations
- UK-based support and productised tax guidance (Radar insights)
- Unlimited Smart Capture OCR unless you pay for add-on
What remains hard
- Compliance and regulation
Stay compliant with our HMRC-recognised, end-to-end solution for Making Tax Digital for Income Tax.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal cloud accounting app (Node.js + Express backend, PostgreSQL, React frontend) that supports: user signup/auth, create/send invoices and record payments, upload & OCR receipt images (use a third-party OCR API), import bank transaction CSVs and auto-categorise, basic double-entry ledger and generate Profit & Loss and Cashflow reports, and a module to generate and send VAT/MTD-compatible returns (mock HMRC sandbox). Out of scope: full RTI payroll, direct bank API integrations (Plaid/TrueLayer), enterprise multi-company features. Include input validation, error handling, unit and integration tests, Docker-based deployment, and documented migration and backup steps.

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.
