The Problem

Legal practices lose $75,000/year to unbilled hours

It's not a productivity problem. It's a capture problem. You're earning money you never invoice — because manual billing is too slow, too tedious, and too easy to shortcharge yourself on.

The Numbers

$75K/year

recovered with 1 extra billable hour/day at $300/hr

🧠

The Memory Tax

Reconstructing your day in 6-minute increments is a real cognitive burden. Quick calls, short emails, document reviews — they all blur together and get written off instead of invoiced.

📋

Invoice Bottleneck

Pulling time entries, formatting them, sending invoices — it takes hours every billing cycle. For right-sized practices, there's often no billing staff to offload it to. It's all on you.

How BillZero Works

Everything you need to bill accurately — nothing you don't

Professional-grade billing without the enterprise complexity or price tag. Built for your practice.

Feature 01

One-Click Timer

Start a timer on any matter with a single click. Switch matters instantly — BillZero stops the old timer and starts a new one. No more "forgot to start tracking" moments. Every minute captured, every time.

Zero friction time capture
Feature 02

Client & Matter Management

Organize your practice the way attorneys think. Create clients, attach matters with unique matter numbers, set per-matter billing rates, and track total hours by client. Your entire practice on one screen.

Full client/matter hierarchy
Feature 03

Paralegal Rate Support

Bill time at different rates for attorneys and paralegals on the same matter. Set client-level default rates or override per matter. Accurate billing across your whole team — even if it’s just you and one paralegal.

Multi-rate billing built in
Feature 04

Instant Invoice Generation

Select a client and date range, preview every billable entry, and generate a numbered invoice in seconds. Line items automatically pull descriptions, hours, rates, and matter names. No manual formatting required.

From entries to invoice in 30 seconds
Feature 05

Your Whole Team. One Subscription.

Everyone logs time — attorney, paralegal, associate. One $49/month subscription covers the entire team. BillZero combines everyone's hours into a single professional invoice with per-person breakdowns and rates. No per-seat pricing.

Single subscription, unlimited team members
Built Different

From timer stop to professional invoice in one click.

BillZero is a billing tool. Period. Not practice management software with billing bolted on. Not an enterprise dashboard with 50 buttons. Just one thing: making sure you bill for every minute you earn.

🚫

No feature tiers

Everything is included at $49/mo. No "Professional" plan gatekeeping the features you need.

🚫

No enterprise upsell

You're not a Fortune 500. Your software shouldn't price itself like one.
