Billing & Payments

Legal Billing & Trust Accounting Software

Lawmox billing turns the messiest part of running a law firm — capturing time, sending invoices, collecting payments, and reconciling trust — into a clean, predictable monthly rhythm. Built for hourly, flat-rate, contingency, and hybrid engagements.

Capture the time you are already working

The single biggest source of lost revenue at small firms is unbilled time. A 12-minute call here, a 20-minute email exchange there, a quick research pull — none of it logged, all of it billable, none of it ever invoiced.

Lawmox makes time entry effortless: per-matter timers, batch entry from your calendar, AI-assisted descriptions, and reminders for staff who forget to log their day. Every entry is tied to a matter, an attorney, and a billing rule, so invoicing is a click instead of a project.

Invoices clients actually understand

Lawmox invoices are clean, branded, and itemized in a way clients can read without calling you to explain charges. Send via email, surface them in the secure client portal, and accept credit card or ACH payments online. Your AR aging stops being a mystery.

Trust accounting that survives a bar audit

IOLTA accounts have rules, and the State Bar of Texas is not casual about them. Lawmox supports trust accounting with strict separation of operating and trust funds, three-way reconciliation, retainer replenishment workflows, and a full audit trail. Your bookkeeper will thank you.
