Walk the job site, talk it through, and send a signed, priced Good/Better/Best proposal before you leave the driveway. Get your 25% deposit the same day. Stringlyne turns a 6-minute job-site walkthrough into a professional, priced proposal your customer can sign and pay on the spot. Built for residential exterior contractors — decks, fences, patios, and general remodels — Stringlyne does the quoting paperwork so you can stay in the field. HOW IT WORKS 1. Walk the site. Talk through the job and snap a few photos. 2. Drop two map pins to measure the area — no tape measure required. 3. Stringlyne builds a Good/Better/Best proposal with real material pricing, labor, permits, and a weather-aware timeline. 4. Send it by text or email. Your customer reviews, e-signs, and pays a 25% deposit from a private link. 5. You get notified the moment it's signed. WHY CONTRACTORS USE STRINGLYNE • Quote on-site in minutes, not nights at the kitchen table • Three priced tiers that help homeowners say yes to more • Material pricing and permit guidance built in • Your phrasing — Stringlyne matches the way you write • Map-based measuring with satellite imagery • Secure deposits through Stripe; money goes straight to your account • Track every draft, sent proposal, and won job in one pipeline NO MORE • Losing the job to the contractor who quotes first • Re-typing the same proposal for every lead • Chasing deposits before you order materials Stringlyne is free to use — no credit card required. Stringlyne is a tool for licensed contractors and their customers. Weather, permit, and property data are estimates to assist your quoting and should be verified locally before you commit to a job.
