Trying to understand integration of multiple zoho projects

Trying to understand integration of multiple zoho projects

Right now I have Zoho projects, freshbooks for invoicing and I use a google docs form for clients to submit tickets which I turn into a task via google app email add on.

It isn't ideal, I am still being overwhelmed by emails and I hate having 3 places. I am looking ad ZOHO support and invoicing but from how it looks these are standalones?  I wanted something like freshbooks, that has invoicing, project management and support all on one otherwise I am just using separate systems again and its too much extra work.

Ideally I would love to create a form for clients to submit tickets directly into my project manager where someone can access and assign it but that isn't working.  I would rather use the tasks system within PROJECTS because I like that it is all together with the clients information already and also because I can still create tasks using email.

I would love to know if there is a better way or some all on one option I am not seeing?  We only have 5 people but we have a lot of client issues.
