Claude Cowork Plugin  ·  by Protomated

Legal Billing & Time Tracker

Log billable hours, generate invoices, manage trust accounts, and review revenue — by chatting with Claude. Your data stays in a Google Sheet in your own Drive. Free replacement for Clio and PracticePanther billing modules for solo attorneys.

🔒 Connecting Google authorizes read/write access to your Sheets and Drive. Your billing data never passes through Protomated's servers. See our Privacy Policy and Terms of Service.

What this app does: Legal Billing & Time Tracker is a Claude Cowork plugin that connects to your Google account to manage law firm billing records by chat. It uses the Google Sheets API to read and write time entries, invoices, and trust account data to a spreadsheet in your own Google Drive, and the Google Drive API to create that spreadsheet on first use. Protomated stores only the OAuth tokens needed to write to your sheet — your billing data never passes through our servers.

What you stop doing manually

Log hours as they happen

"Log 1.5 hours for Garcia immigration matter at $400/hr" — written to your sheet before you forget.

📄

Invoice in one command

Claude shows you unbilled entries, you confirm, it marks them as Billed and sets today's invoice date.

🏦

Trust account records

Deposits and withdrawals with running balance auto-calculated. Safety check before every write.

📊

Revenue at a glance

Total hours, fees billed, collected, and outstanding — pulled from your sheet whenever you ask.


How it works

Install the plugin

Download the .zip from Protomated and upload it in Claude Cowork → Plugins → Add. Takes about 60 seconds.

Connect Google once

Say "connect Google" in Claude. You'll see a sign-in page, authorize Sheets and Drive access, and you're done. Your Google account credentials are handled directly by Google — Protomated never sees your password.

Set up your billing sheet

Claude will create a billing spreadsheet in your Google Drive from the Protomated template, or connect to one you already have. You own the file outright from creation.

Bill by chat

Log hours, run billing reviews, send invoices, record trust transactions — just by talking to Claude. No separate app to open, no tabs to switch.

Compliance-minded by design. Every trust account output carries a reminder to review against your state bar's trust-accounting rules. Every invoice output prompts you to review before sending. The plugin declines any request outside billing and time tracking — it never gives legal advice. ABA Model Rules and state bar compliance remain your responsibility.

Your data, your Drive

Your billing sheet lives in your Google Drive, owned by you from day one. Protomated stores only the OAuth token that lets us write to it on your behalf, keyed to your Google account. You can disconnect or permanently delete your Protomated account at any time by telling Claude — no email required.
