1. A catalogue that looks like a shop
A product grid with photos, categories and search. The alternative, listing items as chat messages, works for five products and becomes unusable at twenty. This is the one feature that decides whether browsing feels like shopping.
2. A cart that survives thinking
People add, change their mind, come back. A cart that holds the selection while they browse is the difference between an order and an abandoned conversation.
3. An order that reaches you with everything in it
Items, quantities, the buyer's handle and their delivery details, in one place. If any of that arrives in a separate message, it will eventually arrive in none.
4. Shipping updates the buyer does not have to ask for
Add a carrier and a tracking number and the buyer gets it in Telegram with the message saying it is on its way. The support question you never receive is the cheapest one to answer.
5. Something that brings people back
Discount codes, gift cards, a loyalty count, a restock alert. Pick one. A returning buyer costs nothing to reach, which makes this the highest-margin feature on the list.
6. Moderation, even in a shop
Where there is a channel there is spam, and a scam link under your product post costs trust you paid for. Anti-spam and link rules run quietly and matter most on the day you are not looking.
7. Numbers that are counted, not estimated
Orders, products, members, what sold. A dashboard that shows real counts is worth more than one that shows impressive ones. The full module list is on Modules, and what each plan includes is on Pricing.
