Link Invoice to Calendar? using for Lawn Business

Trying to find out if I can use this for my lawn company. Ideally, I would like Invoicing and Expenses on ZOHO Invoicing but lacking the scheduling portion. Is there any way to link this ZOHO Invoicing to my Gmail or Zoho Invoicing?

I love everything about this except this feature. May exist but I can not figure it out. 

Also, I am sure there is no way to link this with my bank account is there???
