Microsoft Dynamics 365 Sales

This tool is best for small businesses already deep in the Microsoft ecosystem — think Office 365 and Teams users who need a CRM that plays nicely with what they already use.

The tight integration with Outlook and Excel is a real advantage, but at $65/user/month for the base plan, it's expensive for a small team and carries a learning curve that can slow you down. Most small teams will find simpler, cheaper CRMs like HubSpot or Pipedrive a better fit.
