+# Business address
+
+## Problem
+
+When business uses a communication system for support and other business scenarios, it's important for the customer:
+- to be able to talk to multiple people in the business, and know who they are.
+- potentially, add friends or relatives to the conversation if this is about a group purchase.
+
+It's important for the business:
+- to have bot accept incoming requests.
+- to be able to add other people to the coversation, as transfer and as escalation.
+
+This is how all messaging support system works, and how WeChat business accounts work, but no messenger provides it.
+
+## Solution
+
+Make current contact addresses to support business mode. We already have all the elements for that.
+
+- connection requests will be accepted automatically (non-optionally), and auto-reply will be sent (if provided).
+- the request sender will be made member, can be made admin later manually.
+- the new group with the customer will be created on each request instead of direct conversation.
+
+Group will function differently from a normal group:
+- Show business name and avatar to customer, customer name and avatar to business.
+- Use different icon for customer and for the business if the avatar is not provided.
+- Possibly, a sub-icon on business avatar for customers.
+- Members added by business are marked as business, by customer as customer (not MVP).
+
+This functionality allows to develop support bots that automatically reply, potentially answer some questions, and add support agents as required, who can escalate further.
