We have been using JivoSite for our clients for several years. The service is wonderful for many reasons: 1) Connecting to the website is very convenient (just insert the jivo code on the necessary pages and register in the system) 2) You can choose a plan that suits you (including a free one) 3) The free version offers enough functionality for working with small (and sometimes medium) businesses 4) Communication with clients is done through a familiar messenger interface, which can also be customized 5) There is a mobile app that allows you to communicate with clients even on the go 6) Fast and stable performance. In conclusion: 5 out of 5.
