How to catch one without a price-history tool

No tracker can tell you what you were charged before it existed. These are the checks that work with what you already have.

Read the list, not the statement

Seeing twelve services with their prices side by side makes an outlier obvious in a way that a chronological statement never does. The one that looks wrong usually is.

Check the cycle, not just the amount

Some rises are not rises at all — they are a monthly plan where an annual one used to be, which makes the per-charge figure smaller and the yearly figure larger.

Correct the entry when the scan is out of date

A screenshot taken before a change still shows the old amount. Every line is editable, so the list stays accurate to what you are actually paying rather than to what the image happened to capture.
