Disorganized motorcycle workshops — web app for service, inventory & bookings

About 2,000,000 independent motorcycle and small‑vehicle workshops worldwide still run on paper, WhatsApp threads and phone calls, which leads to lost parts, double bookings, unpredictable cash flow and nearly zero customer lifetime tracking. Those problems hit solo mechanics, small multi‑bay shops and the growing number of fleet/gig operators who need standardized maintenance across disparate vendors. You could build a mobile‑first web app (PWA) that combines job cards, simple inventory with barcode/QR support, appointment bookings, invoicing, basic CRM and a fleet dashboard, with offline sync, SMS/WhatsApp reminders and integrations to online parts catalogs and payment gateways. Price tiers would target $1,200 ARR per typical shop while higher‑touch plans serve fleets and chains, and open APIs enable marketplaces and spare‑parts partners to plug in. The market looks attractive now because smartphone uptake removes the desktop barrier, fleet and gig‑economy growth increases repeat maintenance demand, and parts‑supply digitization makes integrations feasible; these trends underpin an addressable market of roughly $2.4B (2,000,000 shops × $1,200 ARR) and support predictable recurring revenue (market score 88/100, revenue potential 86/100). To stand out you should focus vertically on motorcycles/small vehicles with a truly mobile, offline‑first UX, low‑touch onboarding, local language support and strategic partnerships with parts marketplaces and fleet aggregators to drive volume. Strengths are clear product‑market fit and recurring revenue; challenges are a fragmented global installer base, medium competition, potentially high CAC in some regions and the operational work of localized support and payments — execution discipline will determine whether the unit economics scale.
