What the build includes
Back-office automation uses software and AI to run internal finance, operations and admin processes end to end, such as data entry, approvals, reconciliation and reporting.
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.
A typical scope
- A map of the current process and its exceptions
- Connections to the systems the process touches
- AI steps for reading documents and making routine decisions
- Human review for low-confidence cases
- Logging, so each action can be traced and corrected
Systems it usually connects to
- Practice management software
- Document management systems
- E-signature tools
- Court and research databases
What drives the cost
Work expected to take under a month has a median of $600, against $14,400 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 $500, while hourly posts work out at $9,000 on our estimate: 18 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 | $600 | 6 |
| 1 to 3 months | $6,000 | 26 |
| 3 to 6 months | Too few posts | 1 |
| Over 6 months | $14,400 | 7 |
