AI-Adjusted Flat-Fee Repricing Calculator for Law Firms
Only about a third of solos grew revenue after adopting AI, because hourly billing structurally punishes efficiency: get faster with AI, and you hand clients an unrequested discount. Input your rate, your task times before and after AI, and your volume, and this skill builds a model showing hourly versus flat-fee revenue and suggests price points that preserve margin.

Compliance: never touches your legal work
This automation runs on the rules and values you enter and confirm — it does the arithmetic, you approve every result. It doesn’t draft, decide which rule applies, file, or make any legal judgment, consistent with ABA Opinion 512.

Frequently asked
What do I need to run this?
Claude with Cowork. Install the skill, input your rate, task times, and volume, and it builds the model.
Is this legal or financial advice?
No. It is a pricing and business model from your own numbers. It has no legal advice implications. It shows revenue scenarios so you can decide.
Why is this a Build and not free?
The calculator itself is the deliverable, and it is most valuable paired with the work of actually repricing: retraining intake and rebuilding engagement letters. That combined engagement is where the value lands.
What does it cost?
The repricing engagement is scoped to your firm, typically starting in the Build range of $5k to $15k, or as an ongoing operations-partner engagement. Book a call to scope it.
Want the version built for your firm?
