Formilla offers live chat software to businesses in all industries and works on all sites.” Increase sales and improve customer support with Formilla’s live chat software. Allow your visitors to chat with you live if they have any questions or need support on your website. There is 15 days free trial and paid versions from $19 a month. I really love their simple intuitive interface, mobile app, canned message feature, teamwork, and transcripts via email for all the parties involved.
If you have not a real call center, I really recommend starting using Formilla. In case your need is a chat software for the call center – I recommend Live Chat, Intercom or Zendesk apps.
