I need a clean, mobile-responsive, single–page shopping cart built with Hyfin.app that features several software packages and add-ons with on screen “wet” signature agreeing to terms. After each transaction the customer’s details must flow straight into my Go High Level (GHL) account so that my automations can pick up from there. The flow I’m after is simple: a visitor lands on the page, selects software product and various upgrade options, checks out smoothly on any screen size, and immediately receives the download while their contact record—along with purchase data—appears in the correct GHL pipeline/tag. Deliverables • Hyfin.app page configured, styled to match my brand and fully responsive • Tested native Hyfin.app payment setup for digital software sales • Webhook/API or native integration that pushes customer data into my GHL account in real time • Basic hand-off documentation so I can edit products or pricing later If you’ve connected Hyfin to GHL before—or at least handled similar webhook work—this should be quick. Let me know your estimated turnaround and any clarifications you need.
