The checker is free and runs in your browser. Assisted review reconciles your bills, prepares your questions and follows one case through, for a fixed US$500.
Checks each Fin bill against the terms you enter and Fin’s own export. Nothing is uploaded.
Your record carries what is still open into next month. A renewal comparison is part of the paid review.

Scope. One contract. A supported setup: Fin on Intercom; Fin with Zendesk, Salesforce or another helpdesk; or Fin in Zendesk, counted by tags. Up to three consecutive months.
Renewal comparisons with other vendors are scenarios: they show their assumptions (volume, features, minimums) and never promise another agent would perform the same.
You could try, but a hosted AI assistant would need Fin’s export, which can hold your customers’ names, emails and messages. The checker reads only conversation IDs, dates, states and tags, on your own computer. It applies Fin’s published rules as recorded on a stated date, does the arithmetic in code, and keeps a record from month to month, so the deductions Fin promises are followed into later invoices. The review is the part that takes a person.

Beyond the $51.36, this review is for your renewal decision: your latest bill works out at $3.80 for each resolution a customer confirmed, the last day to give notice is 1 January 2027, and before then you can ask Fin for terms such as its own list of the conversations each invoice charges.
1,284 outcomes charged at $0.99 each where your contract's price is $0.95: $51.36 more than your contract supports. Order form 2026-02, section 3.
The sample’s order form has no committed amount, so none of this is overage: Intercom bills usage over a contracted amount at list price.
Deductions expected on this invoice: 1 outcome. Seen on this invoice: $0.95.
These conversations carry a spam or test tag your team put on them, and the export does not say when: a tag put on before the answer means the conversation was never chargeable, one put on after does not. An export with the time each tag was applied, or a full export, would settle it.
From your teamFin's own list for this period has the same count as the invoice, 1,284, but that does not establish the count: Fin has not confirmed that its export is the list of what it charged and nothing records when the list was taken. What would settle it: Fin's own list of the conversations invoice HSB00001-0042 charges, if Fin will give it.
From FinTeammate replies, requests for a person and returns in another channel could not be checked. This needs the conversations themselves, which this checker never reads.
Previews in Fin's list could not be checked. This needs a column saying where each conversation came from, which this export does not have.

Illustrations, not findings about your bill.
Every 1% adds up. At 10,000 Fin outcomes a month (about US$9,900 at the US$0.99 list price), each 1% of outcomes billed that shouldn’t be is about US$1,200 a year. The free check looks for outcomes priced above your contract, and for the ones Fin’s own rules say to deduct when a customer comes back for more help. Some charges at list price are legitimate overage, and the check takes your terms into account.
Your real price per resolution. Fin bills a resolution whether the customer confirmed it or went quiet for 24 hours after Fin’s last answer. If 30% of your resolutions were the quiet kind, you paid about US$1.41 for each one a customer confirmed, not US$0.99. That’s a value measure, not an overcharge, and it’s the number to take into a renewal. The free check reads it from your own export.
Besides the invoice, the only record of the count is Fin’s own export, and you hold that too. When a customer comes back to the same conversation, Fin’s rule takes the resolution back (Fin’s pricing page), but the invoice does not list these deductions, and standard terms give you no right to audit the count (Intercom’s terms).
Fin bills a resolution when the customer confirms it, or when Fin answers and the customer leaves without asking for more help. Fin’s pages put that silence differently: 24 hours in its billing article (Fin’s pricing page), 3 minutes on its reporting page (Intercom’s reporting page). Fin bills per outcome, a procedure that hands off to your team included (Fin’s pricing page).
Ten of Fin’s billing rules, each in Fin’s or Intercom’s own words, show where else to look.
