Billing for a practice of one.

A solo lawyer needs billing software that covers three jobs done by the same person: recording time, invoicing clients, and keeping client money in trust correctly. Buying one tool for each means copying data between them, which is where solo practices lose billable hours and make trust errors. A web-based system that holds time, invoices and trust ledgers together removes that copying.

Price matters for a practice of one, so look at the per-user cost, whether any feature you need sits on a higher tier, and whether the trial gives you enough time to bill a real matter.

LawAOS runs in the browser and puts time, invoicing and trust accounting in the same workspace. The Solo plan is $29 per user per month, every module is included on it, and there is a 7-day trial with no card required.

The work of billing in a solo practice is small in volume but constant. Each day there is time to record; each month there are invoices to build and send; whenever a retainer arrives there is a trust deposit to post and later a drawdown against an invoice. LawAOS keeps these on the same matter, so the invoice, the time behind it and the client's trust balance are one click apart.

• Record time with a timer that keeps running if the laptop closes, or enter it by hand later.
• Log expenses such as filing fees and courier costs with a receipt attached.
• Build the invoice from unbilled time and billable expenses in a few steps.
• Email the invoice with a PDF and a payment link, then record the payment when it lands.
• Post retainers to the client's trust ledger and run a three-way reconciliation each month.

Is trust accounting included or extra?

Many solo lawyers hold retainers. If trust accounting is a separate product, the client's balance and the invoice will live in two places.

Is the price per user clear?

LawAOS self-serve plans run $29-$119/user/month, and annual billing gives 2 months free. Every module is on every plan; the tiers differ in the AI allowance, included storage and the custom workspace domain.

Does it work from any device?

LawAOS is a responsive web app that can be installed as a PWA. There are no native iOS or Android apps.

Can it grow with you?

If you hire an associate, the same workspace adds approval of their time, roles and permissions without moving to another product.

LawAOS has no free plan. The 7-day trial gives full workspace access without a card, and nothing is charged automatically when it ends; you choose a plan if you want to continue. Free billing tools can suit a practice that only needs to send a handful of invoices, but they rarely include trust ledgers or reconciliation, which is the part a solo practitioner most needs to get right.
