Prumo learns your real labor and material rates from your past estimates — then builds accurate, professional bids in minutes. Not a national average. Not a guess. Your numbers.
30-day free trial · No credit card · Your data stays yours
Built by a working remodeling contractor — we built this because nothing else priced a job the way we actually price jobs.
Not a spreadsheet. Not a wall of numbers. A clean, calibrated proposal your customer can review and approve from their phone.
A plumb line doesn't guess. It doesn't average. It doesn't care what's typical for your zip code. Gravity does the work, and the line shows you what's true.
Prumois Portuguese for that line — the same root as the English word “plumb.”
Most estimating software hands you a national average and calls it close enough. Close enough is how good contractors quietly lose a margin point a year. Prumodrops a line against your own numbers — what you've actually charged, job after job — and tells you when a bid is out of plumb.
The engine calibrates on your own estimates, so every bid reflects how you price — not a generic cost book.
Upload your old estimate PDFs. Prumo scans them for your real rates, then discards the file — we never store your PDFs.
Most contractors are calibrated after 6–8 past jobs in a given scope.
It computes your typical rate per task and builds a live price book that's entirely yours — and keeps recalibrating with every new estimate you send, not just the ones you imported.
Every estimate you send teaches it something. No re-import, ever.
AI writes the scope narrative; the engine prices it from your numbers. Review, set your markup, and send a clean proposal.
Turns your past jobs into your live price book: the median of what you've actually charged, outliers flagged, never silently blended in.
Save any estimate as a template — a returning bath job goes from blank form to priced draft in minutes.
Claude drafts the professional scope wording; pricing stays deterministic and auditable.
Each line tells you where it came from — “median of your 6 jobs,” not a black box.
It applies across the whole estimate. Your margin floor is protected on every bid.
Phases on a visual timeline, with trade-specific starting points for bathrooms, kitchens, roofing, and more — plus a nudge in-app when one runs behind.
Accepted work is protected automatically — price and scope can't change except through a change order, with a signable PDF and a running total.
Your client types their legal name and consents — you get a signed PDF with a real record attached, not just a logged click.
One click opens an email pre-filled with the proposal link — no copying links between apps. Your client reviews and approves right from their phone.
Pick from three PDF styles — modern, classic, or bold — and every estimate, receipt, and change order matches it.
No per-user fees on Starter. One better-priced job pays for a year.
About what other field-service tools charge just to schedule and invoice — Prumo prices the job the way you actually price it.

Yes. Your data is encrypted in transit and at rest, isolated to your account, and never sold or shared. Your calibration engine learns only from your own jobs — your data is never used to price another contractor's work, and no one else's is used to price yours. You can export or permanently delete everything at any time.
No. The AI only drafts the scope-of-work narrative. Every price is computed deterministically from your own historical rates, and each line shows its source so you can audit it. You're always in control of the final number.
You can start bidding right away using a regional baseline for anything not yet calibrated. As you import past jobs — even 6–8 in a scope like bathrooms — the engine locks onto your real rates and pricing gets sharper.
You can upload PDFs, and you can also build your price book as you go — every new estimate you send feeds the engine.
No. We scan each PDF once to pull out your rates, then discard the file — only the extracted numbers ever get saved, in your price book.
Anytime. Export your price book and data whenever you want. It's yours — there's no lock-in.
It's Portuguese for the plumb line — the weighted string that shows you what's true. Same Latin root as the English word "plumb." Our founder is a working remodeling contractor, and the idea is the same: don't guess, drop a line and check it against what's real.
