Legal bill review — automated

Your law firm is billing you.
Are you reviewing the invoice?

The comfort of knowing your legal bill was reviewed — line by line.

Proviso Review analyzes your legal invoices in seconds — flagging block billing, vague entries, above-market rates, and more. A branded report and ready-to-send reduction request, automatically.

The process

Upload. Review. Recover.

Three steps. No legal background required. No prompt engineering. Just upload your invoice and get a report you can act on.

01 — Upload
Drop in your PDF invoice
Upload any law firm invoice as a PDF. Proviso Review reads every line entry — attorney, hours, rate, narrative, and total.
02 — Analyze
AI flags every issue
Our engine checks for block billing, vague task descriptions, above-market hourly rates, duplicate entries, and billing guideline violations.
03 — Act
Report and email — ready to send
Get a branded PDF report with flagged line items and a pre-written reduction request email, ready to send to your law firm.

What we catch

Every line entry. Every issue.

Built by someone who did this work manually for years. We flag the things that actually cost you money.

F-01
Block Billing
Multiple tasks bundled into a single time entry, making it impossible to evaluate the reasonableness of each task individually.
F-02
Vague Narratives
Entries like "research" or "correspondence" with no context or matter connection — unbillable under most outside counsel guidelines.
F-03
Above-Market Rates
Hourly rates benchmarked against current market data for your region and matter type. Know immediately when you're overpaying.
F-04
Excessive Time
Routine tasks billed at multiples of what they should take. Form letters, standard motions, and routine calls that clock in unusually high.
F-05
Duplicate Entries
The same work billed more than once across the same invoice or across multiple invoices on the same matter.
F-06
Guideline Violations
Entries that violate your outside counsel guidelines — or standard billing guidelines if you don't have your own in place yet.
