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