While Convo is not as popular as Yammer, Salesforce Chatter or other enterprise social networks, it’s still a very capable ESN with a dedicated fan base, especially among media professionals, thanks to markup and annotations feature. Convo reviews are mostly positive and pricing is very simple – it’s free for up to 5 users with storage and workgroup limitations, or it’s $9 per user per month. Outside enterprise social networking and instant messaging, Convo doesn’t offer much. There is no true document management or client management or project management. If you are looking for a free Convo alternative, or want to have a choice between cloud or on-premise deployment, or require open source code access for customization and integrations, consider Bitrix24. * Please note that the information may have changed since the publication.
