## What it includes

An AI SaaS MVP is the first usable version of a software product whose main feature depends on a language model or other AI, built to test whether people will pay for it.

Legal builds put confidentiality first. Privileged documents need strict access controls, answers need citations, and a lawyer stays responsible for anything sent to a client or court.

- Sign-up, accounts and billing
- The core AI workflow, including prompts and model calls
- A web interface for the main user journey
- A database and storage for user data
- Usage limits and basic monitoring of model costs

## Systems it usually connects to

- Practice management software

## What drives the cost

Work expected to take under a month has a median of $1,350, against $35,500 for over six months. Part of that gap is built in, because hourly estimates are calculated from expected length. Fixed-price posts state a median of $2,100, while hourly posts work out at $5,750 on our estimate: 2.7 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.

| --- | --- | --- |
| Under 1 month | $1,350 | 10 |
| 1 to 3 months | $4,300 | 27 |
