Park Graph is QR-code parking payment software for any lot: surface lots, truck and trailer parking, event venues, churches, hotels, apartments and private lots. Owners set hourly, daily, weekly or monthly rates (including truck and trailer rates by vehicle type) and print a Park Graph QR sign. No gates, meters, kiosks or hardware. Drivers scan with their phone camera and pay in seconds with no app to download, and payouts go to the owner's bank through Stripe. Features include monthly passes with auto-renew, time extensions from the driver's phone, text and email receipts, gate codes shown only after payment, capacity by vehicle type, an owner dashboard with sessions, revenue and refunds, daily and weekly reports, anti-fake-QR protection on every sign, and a REST API and MCP server so AI assistants can find and book parking. Starter is $0 a month plus a per-payment fee; Pro is $499 a month with a 14-day free trial. Built by Wins Parking, a parking design, build and management company operating since 2016.
