See where your money actually goes

One product, two modes: a privacy-first individual CSV/PDF scanner that never leaves your browser, and a small-business connector for Xero and QuickBooks.

Individual mode

Quickly scan a bank CSV or PDF statement in your browser. No data leaves your device.

  • 100% private — parsing and analysis happen locally; your statement is never uploaded.

Open individual demo

Business mode

Connect Xero or QuickBooks and automatically surface recurring payments, price creep and bank fees — no CSV exports, no manual work.

  • Read-only access — CostWatch can never create, edit or delete anything in your books.
  • Secure OAuth2 login — you sign in directly with Xero/QuickBooks; we never see or store your accounting password.
  • Disconnect any time, from CostWatch or directly from your accounting platform — access is revoked immediately.
