Questions & Answers

As answered by people managing JSON Generator and ProposalPro.

Who are some of the biggest customers of your product?

ProposalPro's answer:

HVAC Contractors -Electricians -Roofers -Plumbers

Which are the primary technologies used for building your product?

ProposalPro's answer:

Next.js and Supabase, with Anthropic's Claude models doing the writing and Whisper-class speech recognition for voice input.

What makes your product unique?

ProposalPro's answer:

Two things. First, grounded AI: the proposal only contains what the contractor actually stated — the pricing table is built from your numbers and the AI never invents brands, quantities, or warranty terms; anything unspecified is listed in an honest Assumptions section your client can see. Second, voice input at $9/month: dictate the job from your phone and the form fills itself — a workflow estimating platforms sell on tiers starting around $149/month.

Why should a person choose your product over its competitors?

ProposalPro's answer:

Because it does one job completely for $9/month flat, no per-user pricing. You bring the price; it produces the professional, signable document — six templates, e-signature via share link, win-rate tracking. If you need CRM, scheduling, or invoicing, a platform tool is a better fit; if the bottleneck is the document that wins the job, this is the fastest path from walkthrough to signed proposal.

How would you describe the primary audience of your product?

ProposalPro's answer:

Solo and small-crew trade contractors who already know their price — roofers, electricians, plumbers, HVAC, landscapers, painters, remodelers, general contractors — plus consultants (engineering, architecture, PM) who need clean fee proposals. US and Canada primarily, with UK/AU tradesman quotes supported.

What's the story behind your product?

ProposalPro's answer:

It started from watching good contractors lose winnable jobs to worse bids that simply looked more professional. Writing the proposal at 9pm after a full day on site is the part of the trade nobody enjoys — so we built the tool that does the paperwork the way a 25-year estimator would, without ever putting words (or numbers) in your mouth.
