Key HighlightsTurnkey vertical SaaS in a stable, recession-resistant niche. BackflowReady is a fully-built, deployed subscription platform for backflow prevention testing contractors — a legally mandated service in virtually every US municipality. Backflow assemblies must be tested annually by law, which creates built-in, non-discretionary, recurring demand for the contractors who are this product's customers.Live, functional product — not a prototype. The app is deployed at backflowready.com with HTTPS, a working marketing site, full authentication, a complete contractor dashboard, and Stripe subscription billing already wired end-to-end.Recurring-revenue business model built in. Three subscription tiers (Starter $79/mo, Pro $199/mo, Fleet $399/mo) with a 7-day free trial, all processed automatically through Stripe with webhook-driven subscription syncing.Massive, underserved market. Tens of thousands of independent backflow testers and small plumbing/cross-connection contractors in the US still run their businesses on paper forms, spreadsheets, and manual reminders. This is a classic "software eats the clipboard" opportunity.Clean, modern, professional codebase. Built on a modern web stack with a polished, mobile-responsive UI and a strong brand identity (logo, color system, marketing assets all included).Complete asset package for the new owner. Includes the full application, database schema, branding assets, and a set of professionally-prepared business documents: competitive analysis, go-to-market plan, and revenue projections.Biggest opportunity for a new owner: growth is purely a sales-and-marketing problem, not a product problem. The product is done. Whoever plugs in customer acquisition (industry Facebook groups, trade associations, Google Ads on "backflow test software," or direct outreach to testers) captures the upside.OperationsWhat the business does: BackflowReady is a software-as-a-service platform that gives backflow prevention testing contractors everything they need to run the compliance side of their business in one place. Instead of juggling paper test reports, spreadsheets, and sticky-note reminders, a contractor uses BackflowReady to:Maintain a device registry — track every backflow assembly they service (RPZ, DCVA, PVB, and other device types), including location, hazard level, size, make/model, serial number, and current status.Capture test results — record gauge readings, pass/fail results, and test dates, with the tester's signing details attached to each report.Stay ahead of compliance deadlines — the platform automatically tracks the annual re-test deadline for every device so contractors never miss a required test (the event that drives their own revenue).File with water purveyors — organize which water authority/purveyor each device reports to, including filing method and contact details.Manage customers — keep a full customer list (commercial and residential properties) with contact and address details.Generate invoices — create and track invoices tied to completed tests, with paid/unpaid status.How it makes money: Revenue comes from monthly recurring subscriptions. Contractors sign up, start a 7-day free trial, and are then billed automatically each month on one of three plans (Starter/Pro/Fleet) based on how many devices and users they need. All billing, trials, upgrades, and cancellations are handled automatically by Stripe.What's required to keep it running: Very low operational overhead. The app is hosted on a fully-managed cloud platform, so there are no servers to patch or maintain manually. Ongoing work consists of:Customer support / onboarding questions (email-based)Occasional feature improvements and bug fixesMarketing and sales to acquire new subscribersEstimated time commitment: As a hands-off, product-complete SaaS, ongoing maintenance is minimal — realistically a few hours per week for support and light upkeep. The variable is how much time the owner chooses to invest in growth/marketing, which is where the real opportunity lies. This is an owner-operated side business today with room to scale into a full-time venture.CustomersWho the customers are: The paying customers are backflow prevention testing contractors — independent certified testers, small-to-midsize plumbing companies, and cross-connection control specialists operating in the United States. Their end-clients (the properties whose devices get tested) are commercial buildings, medical facilities, schools, restaurants, apartment complexes, and municipal/industrial sites.Why they're a strong customer base:Legally captive demand. Backflow testing is mandated by local codes and water authorities on an annual basis. Contractors don't buy this software as a "nice to have" — they need a reliable way to track mandatory recurring compliance work, or they lose track of billable jobs.High retention potential. Once a contractor loads their device registry and customer list into the platform, switching costs are high — the software becomes the operational backbone of their recurring revenue. This is a naturally sticky, high-LTV customer profile.Repeat/recurring by nature. Because their own business is built on annual re-tests, the value the software delivers compounds every year, reinforcing the subscription.How customers are acquired: The included go-to-market plan details the primary channels — targeted outreach in contractor Facebook groups and trade communities, industry associations, YouTube/LinkedIn content, and paid search ads aimed at testers actively looking for software. Customers are primarily domestic (US), since backflow compliance rules are US-jurisdiction-specific, which keeps marketing focused and efficient.FinancialsBusiness model: Monthly recurring subscription revenue (MRR) via Stripe.Pricing tiers: Starter $79/mo, Pro $199/mo, Fleet $399/mo — each with a 7-day free trial.Current MRR: $0 — this is a newly-built, pre-revenue product being sold as a turnkey launch-ready asset.Active subscribers: 0 — no marketing or customer acquisition has been conducted yet.Operating costs: Near-zero. Hosting is on a managed cloud platform with no infrastructure contracts or obligations. Stripe charges standard processing fees (2.9% + $0.30) only when revenue flows. There are no employees, no paid tools, and no recurring vendor commitments that transfer with the sale.Gross margin potential: As a pure software product with negligible per-user cost, gross margins at scale are 85–90%+, consistent with vertical SaaS benchmarks.Revenue potential: At just 50 subscribers on the mid-tier Pro plan ($199/mo), the business generates ~$10K MRR / ~$120K ARR. The included revenue projection models detail conservative, moderate, and aggressive growth scenarios.Why pre-revenue is the opportunity, not the risk: The product is fully built and functional — not a wireframe or an MVP. The buyer is acquiring a finished, deployable SaaS product in a market with legally-mandated demand and no dominant incumbent. All the development cost and time has already been spent. What remains is purely go-to-market execution, meaning the new owner captures 100% of the growth upside without any of the build risk.Additional NotesWhat's included in the sale: The complete deployed web application, full source code, database, the BackflowReady brand identity (logo, icons, color system, marketing posters), the premium exact-match domain backflowready.com (already live with HTTPS), and a professional business document package — competitive analysis, go-to-market plan, and revenue projections.This is a launch-ready acquisition. The product doesn't need months of development before it can accept paying customers. It is live, functional, and accepting signups today. The new owner can begin marketing immediately.Clean handoff with minimal transition: No employees, no vendor contracts, no complex infrastructure. The buyer sets up their own Stripe account, swaps in their API keys, and they own a fully operational SaaS business.Reason for selling: Built as a focused vertical-SaaS project; selling to pursue other ventures.Growth roadmap for the buyer: Mobile field app for on-site testers, automated electronic filing to water purveyors, SMS appointment reminders, multi-state jurisdiction expansion, and partnerships with backflow certification training programs — all high-value feature additions that deepen lock-in and justify price increases.
