Real resolver output from the hvac 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 hvac 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.

HVAC estimating — common questions
How fast can I quote a change-out?
Minute one. Pick HVAC at signup and the pack loads — cooling, heating, heat pumps and mini-splits, ductwork and IAQ, maintenance. Enter the tonnage or zones and the system prices as you go.
What does ScopeToSign do about the 2025 A2L refrigerant change?
It's built in. New condensers price at the A2L (R-454B/R-32) era; the pack raises a lineset-compatibility flag on a reused lineset and starts the replacement conversation when the old unit is R-22 — so the quote matches what actually gets installed.
Does it build the Good/Better/Best options for me?
Yes. Toggle Good/Better/Best on a system and the pack scopes each tier — a two-stage step, a float switch and surge protector, a variable-speed inverter — with the price delta shown per option.
Does it work on my phone at the truck?
Yes — it's web and mobile, the same tool. Quote from the driveway on your phone, finish at the shop on a laptop; edits sync and survive a dead battery.
What does ScopeToSign ask to price a system replacement?
Only what changes the price. The hvac pack asks: Tonnage on data plate? Indoor unit age (matched-system conversation)? Lineset length/route accessible? Panel amps? Does the old unit use R-22? Every answer maps to a real line — nothing is invented.
Can I bid commercial mechanical plan-and-spec work with it?
No — that's the honest boundary. ScopeToSign prices residential and light-commercial service work from a price book, not off blueprints. For sheet-metal and mechanical takeoff on commercial plan sets, a suite like FastDUCT/FastPIPE or a dedicated mechanical takeoff tool fits better. This is built for change-outs and service calls.
