Real resolver output from the plumbing pack’s researched defaults — integer cents, nothing hand-typed. The permit is a pass-through billed at cost; the highlighted rows are the items low quotes leave off.
No blueprints. Quote from a photo, your voice, or a note.
No blueprints needed — quote from photos, voice, or a quick description.
Snap the old unit, hold the button and talk, or paste a line of text. The AI reads what’s there, matches it to your plumbing tasks, and drafts the estimate — asking a question chip when it isn’t sure instead of guessing. It never sets a price: every number still comes from your price book.
If the AI is down, nothing stops — you search and add tasks by hand and the estimate is complete. The AI is an accelerator, never a dependency.
From estimate to signature
Estimating gets the number right; closing wins the job. When the estimate is ready, turn it into a Good/Better/Best proposal your customer opens on their phone — three clear options with the delta spelled out, the scope of work, and what’s not included. They pick one and sign with a typed name; you get an evidence-grade acceptance record and a PDF.
Deposits are collected on the contractor’s own Stripe account when that feature is enabled — never on our balance. Changes after acceptance become numbered change orders, so the signed estimate stays locked.

Plumbing estimating — common questions
How fast can I price a plumbing job?
Minute one. Pick plumbing at signup and a full price book loads — water heaters, fixtures, drains, repipe, gas, sump and laundry. Search a task, tap the input chips, and the price resolves as you go.
Does it do flat-rate or time-and-materials?
Both. Most tasks are flat-rate from the pack; parametric jobs (a repipe by fixture count, a gas line by the foot) compute from your rates. Add a custom line any time with a markup helper.
Does it work offline in a crawl space or basement?
Yes. Edits queue to the device when you lose signal and sync when you're back up, with an undo if a sync conflicts. You never lose work in a basement with no bars.
Is the price book really mine to edit?
Yes. Every task, rate, and markup is editable, and you can export your pricebook and estimates to CSV or JSON. The pack is a fast start, not a cage.
What does ScopeToSign ask to price a water heater?
Only what changes the price. The plumbing pack asks: Gas or electric today? Tank size? Location? Pan/alarm present? Shutoff age? Every answer maps to a real line — nothing is invented.
Can I bid commercial plan-and-spec plumbing work with it?
No — and that's the honest boundary. ScopeToSign prices service work from a price book, not blueprints. If you quantify off plan sets for commercial bids, a purpose-built takeoff suite like FastPIPE or McCormick fits that job better — they're built to measure and count off drawings. This is for the repair-and-replace service side.
