The builder's field office.

01 · The estimating flywheel

A lumber package isn't “$6,000” — it's five-to-seven. So estimate in bands, one per line. Record the actual when the invoice lands; see the verdict. Ten jobs in, you own an estimating database priced from your own history.

“Flagged it as the likely line to break band when I estimated. Next job, windows get a wider band and an earlier order date. That's the whole point.”

CHECKLIST 22/32 · 69%

Foam day — building sealed. Inspection #4 tomorrow.

02 · The client portal

A calm, branded page: where the job stands, site photos, the documents you choose. No costs, no logins. Builders close in the driveway — “this is what you'll see every evening.” The portal is the pitch.

Builder

Everything, every project.

Bands, actuals, bids, procurement, inspections — the whole company in one binder.

PM

Everything on their job.

Full project view including money. Scoped to the project, nothing else.

Sub

A link, not a login.

Checklist and the drawings — big targets, works in sunlight. Never a dollar figure.

Client

The dream-house ritual.

Progress, photos, shared documents. Calm, branded, read-only.
