Shop, courses, bookings, tickets, subscriptions, delivery, utilities - seven payment-bot shapes, when to use a chat bot vs a Mini App, and what a production checkout looks like.
A concrete payment-bot example for educators: catalog of courses, invoice, webhook, then a private channel invite, files, or a lesson Mini App. Installments and Telegram Stars included.
A payment-bot example for appointment businesses: calendar in a Mini App, 20-50% deposit, reminders, reschedule rules. Empty slots stop being free options held by people who never show up.
A payment-bot example for product sellers: Mini App catalog, variants, cart, Nova Poshta or courier, Mono / LiqPay / Stripe, fiscal receipt, and order statuses in the chat.
