You canceled it in April. It's still on the bill in December.

A cancellation is a phone call. The bill is a system. The system wins.

One line on one bill

A dedicated fax line, disconnected on April 15. May's bill: $42 for the fax line. June's too.

Eight months later it had charged $336 for a line that didn't exist.

Sample data

How TIP knows

At onboarding TIP takes your service change log: what was canceled or disconnected, and when. TIP's team checks each entry with you and keeps it.

From the effective date on, any charge for that line or feature is a billing error. A cancellation that actually stopped billing is left alone.

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.
