I have 40 fully-prepared driving lesson packages that I want to sell directly through WhatsApp. All course materials, pricing, and bundle details are finished; what I lack is a smooth sales funnel inside WhatsApp itself. I’m still weighing whether a simple WhatsApp Business catalogue will do, if the official WhatsApp API would give more flexibility, or if a third-party tool makes better sense. I’ll rely on your advice here—please explain the trade-offs, expected running costs, and any approval steps so I can pick the best route quickly. Once the platform choice is locked, I’ll need you to: • Build or import a clean catalogue listing for the 40 lesson packages, including thumbnails, short summaries, and prices. • Create automated welcome, nurture, and follow-up message templates (broadcast or one-to-one, depending on the chosen setup). • Integrate payment links or an inline checkout so students can pay and receive instant confirmation inside the chat. • Set up tagging or simple CRM hand-off so I can track enquiries, paid students, and lesson progress. • Provide a brief hand-over guide and a 30-minute walk-through call so I know how to maintain or tweak the system myself. Acceptance criteria 1. Every package appears correctly in WhatsApp with description, media, and price. 2. A first-time user can move from initial enquiry to completed payment without manual intervention. 3. All automated messages send in the right sequence and display no template errors. 4. I receive a concise, clear user manual and recording of the hand-over session. If you have recent experience launching course or service sales on WhatsApp—especially with payment integration—let me know. Links to similar workflows you’ve built will help me choose quickly.
