UK freelancers pay for the tax integration — self-assessment, VAT, and payroll — because accounting software that does not file the UK forms is a ledger with ambition.
REPLACEMENT BRIEF
finance & accounting
Can AI replace FreeAgent?
Invoicing and expense tracking is a buildable finance app — the model is a register. The product's moat is the UK tax layer: self-assessment filing, VAT, payroll, and bank feeds tuned to UK rules — the compliant books, not the ledger.
Build a freelancer bookkeeping app that tracks project expenses, generates recurring invoices, and monitors bank cashflow.

the prompt
Catalog estimateBuild the closest honest consolation tool inspired by FreeAgent; do not claim to replace its structural moat. Use exactly this stack: Next.js 15 + TypeScript + SQLite. Primary job: Build a private small-business accounting ledger that imports user-supplied CSV files, categorizes entries, reconciles balances, and exports reports. Start from an empty folder and create the complete working project. Make the default mode single-user and private. Store user data locally unless the core job requires the declared self-hosted database. Do not add analytics, telemetry, ads, or third-party accounts. Put every secret and external credential in .env and provide .env.example. Use realistic sample data that is clearly labelled and easy to delete. Implement the smallest polished interface that completes the core loop end to end. Include clear empty, loading, validation, success, and failure states. Add import and export so the user is not trapped in the app. Use accessible keyboard navigation, labels, focus states, and sensible contrast. Validate untrusted input and never log secrets or private file contents. Deliberately exclude these paid-product advantages: bank, payment, tax, and reconciliation integrations; live bank feeds and payment rails; tax and accounting rule updates. Do not fake integrations, network effects, proprietary data, model quality, compliance, or security claims. Where an external API is optional, keep the app useful without it and explain the degraded mode. Write focused unit tests for the data model and the most important workflow. Add one end-to-end smoke test that proves the core loop works. Create a README with setup, permissions, architecture, data location, backup, and limitations. Add scripts for install, development, test, build, and a production-style local run. Run the tests and build before finishing, then fix errors rather than merely describing them.
