A $50 line. A $2,450 month.

Sometimes there's a reason. Sometimes there isn't. Either way, somebody should ask.

One line on one bill

A mobile line that costs about $50 a month, ten months running. Then one month: $2,450. Most of it one item, international roaming, pay-per-use.

Maybe someone travelled. Maybe nobody did.

How TIP knows

TIP learns each line's own normal from its own history. A month far above it, by a multiple and by real dollars, is flagged, with the line item that caused it.

TIP calls this what it is: a pattern worth your attention, not proof. It carries the lowest confidence TIP will show you, so if you have narrowed what TIP files without asking, this one always comes to you first: TIP shows you the line and the math, and you decide. On the setting TIP comes with, TIP files it too, and if there was a reason, the carrier says so.

What TIP does about it

Every billing error comes with the line item, the amount and the reasoning, in plain English.

By default, TIP does the rest: files the dispute with your carrier, follows up until the carrier answers, and tells you when the credit lands. Every dispute and every carrier answer is in your Dispute Tracker. No work on your side.

Want TIP to ask first? Your call, any time. Every billing error TIP finds carries a confidence score: how sure TIP is that the carrier owes you the money. TIP comes set to file a dispute for every error it finds, whatever the score. If you'd rather TIP file fewer on its own, raise the bar: file only the high-confidence errors (85% and up), or only the near-certain ones (90% and up), and TIP brings every error under the bar to you to approve first. Or turn automatic filing off, and nothing is filed until you say yes. It's one setting in TIP, and you can change it any time.

Either way, TIP checks the next invoice for the credit. A credit promised and never paid is a billing error too, and TIP goes back for it.
