# Using BillGuard

Canonical page: https://billguardapp.com/en#flow

## Workflow

1. [Create an account](https://billguardapp.com/en/signup) or [sign in](https://billguardapp.com/en/login).
2. Open the authenticated upload page and upload a clear JPEG, PNG, WebP or PDF file, up to 8 MB, or enter details manually.
3. Check extracted amounts, dates, usage, units and identifiers against the original bill. Missing or unreadable evidence can limit the analysis.
4. Read the findings and verify suspicious lines with the provider. Add comparable previous bills when you need historical comparisons.
5. With eligible paid access, export the evidence pack or prepare a dispute letter, review it, and contact the provider yourself.

## Evidence and limitations

A first bill without comparable history is a current-bill review. It cannot establish a month-over-month change, a personal average or a historical trend. Missing historical data is not evidence of an abnormal increase. Different units, billing periods or meter-read types may make bills unsuitable for comparison.

Potential savings are estimates, not money recovered. BillGuard does not automatically dispute a charge, pay a utility bill or provide a binding legal determination. Users should verify findings and local dispute requirements. Educational tools and example results are not a diagnosis of a user's own bill.
