# WorkGrid Pro

> Lightweight operations software for specialty contractors focused on estimate revision history, change orders, markup/margin, and digital approvals.

## Product
- Name: WorkGrid Pro
- Audience: remodelers, painters, flooring installers, roofers, specialty subcontractors
- Core workflow: customers → projects → versioned estimates → change orders → approval log → job margin
- Not an ERP: no payroll, no accounting replacement, no deep integrations in v1

## Key facts
- Estimate versions become immutable once sent or accepted; revisions create a new version
- Change orders support templates, PDF export, email notifications, and tokenized client approval
- Markup calculator converts cost + markup % to sell price; margin = (price − cost) / price
- AI assist can rewrite line descriptions, draft change-order explanations, summarize margin risks, and generate proposal text (user must review before sending)
