Problem

Service contractors often build estimates in disconnected documents, making margin risk and approval state hard to see.

Approach

A focused estimate workspace with editable line items, server-independent seeded data, financial summaries, and an explicit approval sequence.

Evidence boundary

  • Fictional portfolio demo only. No real customer, revenue, approval, or ROI claims are presented.
