Generic proposal tools can't price trade work
Most contractors reach for one of two kinds of software to send a proposal, and both leave the same gap: the price. A document tool makes the page look professional; a field-service suite runs the schedule. Neither actually prices the job the way a tradesperson does, so the number still comes from somewhere else — usually a spreadsheet, a memory, or a guess.
Document tools don’t know your trade
A generic proposal app makes a clean PDF, but the price still comes from a spreadsheet you keep on the side. There’s no water-heater task, no tonnage math, no forgotten-item catch — just a text box you type a number into. The document looks like a proposal; underneath, it’s a formatted guess. And when you forget the permit or the haul-away, the tool has no idea, because it never knew the job in the first place.
Suites bury the estimate
A big field-service suite can quote, but pricing is one tab among scheduling, dispatch, invoicing, and a dozen other modules — shallow exactly where it matters most. You adopt the whole platform, learn the whole platform, and pay for the whole platform to get a quote box that still doesn’t know a 3-ton change-out from a faucet swap. The estimate is the thing that wins or loses the job, and it’s the thing a general-purpose suite is least likely to nail.
What “built for the trades” actually means
Not a tagline — three concrete things a proposal tool has to do that a document editor can't.
A real price book per trade
Plumbing and HVAC each ship as a pack of real tasks with their own inputs, formulas, and add-ons — a water heater priced by size and venting, a system priced by tonnage and zones. It’s your book to edit, loaded in minute one.
A review engine that catches misses
Before a proposal goes out, deterministic rules check for the expansion tank, the permit, the pan the code wants. A rule can block the send; the AI only ever warns. A generic tool has nothing to check against, because it has no idea what the job needs.
An evidence-grade signature
When the customer picks an option and signs, you get an immutable acceptance record — the option, the version, the timestamp — plus a PDF. If a deposit is disputed later, the evidence assembles itself. That’s the difference between a signed image and a record that holds up.

Contractor proposals — common questions
What trades does it cover today?
Plumbing and HVAC, each with a real price book — the launch pair. More trades are packs plus a landing page, added once the launch trades show retention; we won't fake a pack we haven't built.
How is this different from a generic proposal tool?
A generic tool makes a pretty document but can't price the work — you paste numbers from a spreadsheet. ScopeToSign prices the job from a trade pack, then presents it as the proposal, so the number and the document are the same thing.
Can I collect a deposit when the customer signs?
Yes, when deposit collection is enabled. Deposits are charged on your own Stripe account, never our balance. It stays off until the Connect setup is complete.
Does the customer need an app or account?
No. They open a link on any phone, pick an option, and sign with a typed name. It works with no JavaScript as a read-only document, too — so a homeowner on an old phone in a basement still sees the whole proposal.
Will a comparison or umbrella page rank right away?
Honestly, probably not first. An umbrella page like this earns its ranking as the trade pages it links to gain authority — it's a patience page by design, not a quick win. We'd rather tell you that than pretend a category term ranks overnight.
What happens after the customer accepts?
You get an evidence-grade acceptance record and a PDF, and a deposit if it's enabled. If the job changes, a numbered change order adds the delta on top of the locked, signed proposal — no re-quoting, no arguing about what was agreed.
Proposal software that prices the work
