Start here

Choose the utility bill problem, then open the right tool.

Utility bills are easier to solve when the first page matches the problem: high usage, a confusing line item, one expensive appliance, a possible leak, or a savings target.

Before you choose

1

Compare usage per day before comparing dollars.

2

Separate variable charges from fixed fees.

3

Check whether sewer follows water usage.

4

Use a scenario page when one appliance, leak, or outdoor use changed.

Pick the first signal

Route the bill by what changed first.

Use the strongest clue on the bill before opening the full list. That keeps a water leak, a kWh spike, a fixed-fee change, and a payment issue from being mixed together.
