Track Employees via Zoho Invoice

Track Employees via Zoho Invoice

I am trying to transition from Quickbooks to Zoho for my invoicing needs.  In Quickbooks I am able to select which of my employees booked the business so they can get paid a commission.  How can I include the proper fields so all of our sales people are properly tied to each invoice and payment?  

When the integration occurs with Zoho CRM will this be standard?
