Monthly Web Designer CRM

I’m a web designer who sells websites on a monthly payment basis rather than an upfront cost. I also offer social media management on a subscription basis. I’m looking for a CRM that can offer the below:

Gmail Intergration Project Management Xero integration Subscription revenue tracker – this is the big one. I want to be able to see how much revenue I’ll get each month rather than one yearly deal price. Contract/e-sign

I know I’m asking for a lot but keen to see if there’s something out there that I don’t know about.
