Looking to see if you have a CRM plugin

I am helping to manage a small business, which I am currently using Filemaker’s Bento program as my database. It does the job pretty well but has the limitations of needing synced as their are currently 2-3 employees. I would like to integrate a cloud based CRM tool, possibly something that integrates with Appointments+. The goal is to have something that I can access from anywhere and have myself and the other two employees enter and retrieve client details. Also was hoping something that I can easily edit the fields.
