Real-Time Messenger

Provide your customers with a tool to chat with vendors


This product is electronically distributed.


The Real-Time Messenger add-on is a perfect tool for realtime messaging between customers and vendors.

Providing customers with a tool to chat with vendors on the fly is a good opportunity to amaze your customers with exceptional service! If any question arises, it can be immediately addressed to the vendor. The vendor gets email notification and replies to the customer in order to answer the questions, dispel doubts or convince them. It’s obviously a good chance to help customers make their purchase decision faster. Buy additional server configuration not to worry about add-on configuration on the server!

Server Configuration

Configuration of the add-on work on the server might be challenging, so we recommend purchasing our configuration service in addition to the add-on. 

Note that technical characteristics and configurations of servers may vary and directly depend on the company providing the hosting services, so add-on installation and setting up the server configuration are guaranteed only for Simtech Development hosting.

In other cases, we do assure you that we will make every effort to configure and install the add-on. But we do not take responsibility in situations when, after the work on configuring the server done, it was not possible to achieve the proper operation of the add-on because of the action or inaction of third parties, including the hosting provider.
