Looking for a chat software which can be integrated on multiple websites and web pages on one time payment, as most of the software provide license depending on the number of web pages and sites count.
Personally I would like to suggest that you may try eAssistance Pro live chat which offers to take free trial to checkout software's features and functionality before purchasing it. If you will be satisfied with this performance then you can activate your subscription plan as your requirement. For more information visit on https://www.eassistancepro.com/
