One system for cost history, the estimate, and the bid.

Past projects become the next estimate
Zebel turns completed project costs into a structured database you price the next job from.
That number carries through to the bid
Conceptual budgets, detailed estimates, bid leveling, and GRs/GCs stay in one file.
Review it before the number goes out
AI Oversight flags scope gaps and anomalies before bid day. You still make the call.
