Cost follows process complexity, integration count, and risk controls more than model brand names. A single read-only research agent on clean documents prices far lower than a write-capable ops agent across three systems of record. Local rates for senior engineers sit near other mid-Atlantic tech markets, and project fees track hours for discovery, build, evals, and hardening. License costs for model APIs and monitoring stack on top as variable spend you can cap. Discovery length changes the fixed fee. When owners already know the process map and can grant sandbox access, we cut weeks of reverse engineering. Messy shared drives and unverified SOPs expand that phase. Tooling that already exposes stable APIs also reduces custom adapter work. Charlottesville university-adjacent teams often have strong identity systems which helps, while smaller shops may need connector time. Risk class also moves the number. Healthcare-adjacent data needs redaction, tighter logging, and longer security review. Payments and refunds need human gates and stronger audit packs. Those additions are deliberate and priced as scope, not surprises on the final invoice. You see them on the estimate with options to phase later. Ongoing run cost is separate from build. Token use, vector storage, and observability sit in monthly ops. We design caches, cheaper model tiers for easy steps, and hard spend ceilings so the bill cannot drift silently. Ask for a model of p50 and p95 task cost on your sample volume before you approve production cutover. That habit keeps finance aligned with engineering from day one.
