Almost all companies big or small use some of the shelf software, particularly for non-critical processes (that is because your data is stored on vendor servers). One of the most popular SaaS solutions is for internal company communications offered by Slack. It is better organised and allows you to set up multiple workspaces, share files, set up meetings using video and audio and numerous other robust features. It would make no sense for a company to create its own custom communication solution. Further while data shared within the company might be important and easily searchable it is still not mission critical. The organisation using the service might at any time switch its allegiance to another SaaS service with no disadvantage. Other popular SaaS solutions are CRMs like Salesforce and HubSpot. Salesforce CRM boosts an organisation sales process by managing leads and prospects in one place. HubSpot CRM is focused on inbound marketing through advanced technological features and is expanding its services to social media marketing and content management. Atlassian JIRA for project management, MailChimp and Google Application (G Suite) are other examples of popular SaaS solutions that are ruling the market right now.
