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.”
