Just the estimation engine — not the bundle
Bids that recompute themselves.
Stop maintaining 33 line items by hand. Add a line, the subtotal updates. Drop a line, the Excluded list updates. Change the fee, every reference in the bid stays in sync.
4011 Amherst — Patten Custom Homes' canonical $348k remodel — pre-loaded.
Sample project
4011 Amherst — Remodel + Addition
Live totals
Add a line, drop a line, change an amount. Subtotal, fee, grand total update instantly. No formula bar.
Cross-references stay in sync
When you remove line 25, the Excluded list, scope text, and §11 summary all update. Errors caught before the client sees them.
Builder-shaped, not accountant-shaped
Designed around how contractors actually negotiate — add, drop, reduce, swap. Not journal entries.
One engine. One price.
You don't need the full Cortivex bundle. Buy just the estimation engine. Same data model Patten Custom Homes uses on every job.
