Every other invoice you pay gets audited. Legal bills don't. BillingLens reads the engagement letter, audits every invoice line by line, and drafts the dispute letter — so you pay only for work that was actually done.
Built on billing standards attorneys already use
A divorce client receives a $14,000 invoice and has no framework to read it. A small-business owner gets a bill for "attention to matter" and can't tell whether to question it. The systems that keep us honest about every other expense stop at the lawyer's door.
Firms bill by time claimed. Independent verification is the exception, not the default. The honest firms suffer because there's no way to tell them from the rest.
"Attention to matter, 3.2 hrs." Block billing, vague entries, no backup. The most expensive line on your monthly statements is the least itemized.

BillingLens sits between you and your attorney's billing system. It reads the paperwork, watches the bills, and gives you the right question to ask — every time.
Reads your engagement letter. Pulls out hourly rates, minimum increments, scope, and who pays for what. Every later invoice is audited against this baseline.
Line-by-line AI review in under 60 seconds. Block billing, rate mismatches, admin-task padding, duplicates, and benchmark anomalies — all flagged with confidence scores.
Live dashboard of retainer balance, cumulative spend, and forecast. Alerts before the retainer runs dry — not after.
Flags become a precise dispute letter — citing your engagement-letter clauses — for you to review and send. You're the one talking to your firm. We just hand you the words.
Pay only what you've approved. BillingLens routes the payment after your sign-off, with cash-back on processed amounts.
Ask "what is this charge?" Get a clear answer and the right question to bring back to your attorney. Information, not advice — your lawyer stays in the loop.
You don't need to learn the law. You just need a tool that reads with you.
