01 · The estimating flywheel
Every job makes your next estimate sharper.
You already know a lumber package isn't “$6,000” — it's five-to-seven. ashiba lets you estimate the way you actually think: a band per line. When the invoice lands you record the actual and see the verdict — under, in band, or over. Do that across a job, then across ten jobs, and you own something no spreadsheet gives you: your private 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.”

02 · The client portal
Show homeowners what they'll get — before they sign.
Your client gets a calm, branded page: where the job stands, photos from the site, the documents you choose to share. No costs, no chaos, no login gymnastics. Builders close jobs by pulling it up in the driveway: “this is what you'll see every evening.” The portal is the pitch.

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.

Software by someone who's actually built something.
Every feature is proven on a live job before it ships. Currently: a backyard office building in the Texas Hill Country.
