Features
A second set of eyes on your legal spend
BillingLens helps individuals understand legal agreements and track spend— clarify their legal invoices with their law firms when needed.
Feature Highlights
Five ways BillingLens brings clarity to legal spend
Compare Agreements
Instantly compare new agreements to past engagement terms.
Upload your representation agreements to instantly compare them against past terms and practical market standards. BillingLens highlights discrepancies in hourly rates, scope of work, and staffing so you never sign blind.

Agreement Insights
Cut through legalese and flag hidden risks.
Don’t let complex legal jargon hide aggressive billing terms. Our AI summarizes key clauses and flags unreasonable increments or scope gaps early, giving you the context needed for a smarter discussion with your counsel.

Review Invoices
Catch missing hours and hidden billing leaks with automated invoice review.
Reviewing every line item is exhausting. BillingLens automatically reviews bills against your engagement terms, instantly flagging block billing, seniority creep, prohibited administrative overhead, and duplicate entries. Only pay for the work you agreed to.

Budget Tracking
Total visibility into matter spend vs. your legal budget.
Move beyond static spreadsheets and end-of-quarter invoice shock. Get real-time dashboard views into your total legal spend, matter-level burn rates, and overall budget health so you always know where you stand.

AI Assistant
Ask plain-English questions. Get cited answers in seconds.
No more digging through documents. Ask BillingLens anything about your invoices, agreements, or billing history and get answers grounded in your actual data — with citations back to the source.

Why Trust BillingLens
Trust and Verify
Human-assisted agentic AI that shows its work. Every flagged line item is backed by deterministic rules, cited sources, and expert validation — not black-box guesses.
Protected AI
Your documents never train our models. BillingLens runs on isolated, single-tenant AI infrastructure with zero data sharing. Every analysis is ephemeral — processed, cited, and discarded from model memory.
Deterministic Rules Engine
Not just AI — our flag engine combines hard-coded compliance rules with LLM analysis. Rate math, billing increments, and fee cap checks are deterministic. No hallucinations on the numbers that matter most.
Cited Sources & Ingested Data
Every flag cites its source: your engagement terms, ADA billing guidelines, Clio benchmark reports, and jurisdiction-specific rules. You see exactly why something was flagged — not just that it was.
Human-Assisted Agentic AI
Our AI acts autonomously — but nothing reaches you unchecked. Every flagged item is scored by confidence level, and when confidence is below threshold, legal billing experts validate the finding before it appears in your queue.
Take back control of your legal spend
BillingLens empowers you to catch hidden charges, enforce your engagement terms, and professionally request billing clarifications without damaging your attorney relationship.
