Description

Chatmart turns a WhatsApp Business number into a shop counter and a booking desk. A customer messages the number and, without leaving the chat, browses a catalog, places an order, pays, and books a real appointment slot. They install nothing, open no link, and create no account.

What makes Chatmart different
Native in-chat forms. Chatmart implements WhatsApp Flows, Meta’s official in-chat form system. The customer fills in a structured form inside WhatsApp rather than tapping through to a web page. Payloads are encrypted with RSA-OAEP and AES-GCM exactly as Meta’s specification requires.

Live slot availability. The times offered to a customer are calculated at the moment they open the picker, against existing bookings, the service’s duration, staff capacity and the branch’s opening hours. A slot taken seconds earlier is not shown, so double-booking cannot occur.

One installation, many locations. Each branch has its own WhatsApp number, currency, language, opening hours, catalog and staff. Branch separation is enforced by a database-level query scope rather than per-screen filtering.
