We are setting up a new client who wants to keep track of the Vacation Earned for each employee who has a different role in the company.

This can be set up through Payroll Expense Groups.    Each payroll Expense Group can be assigned to different G/L expense accounts (and probably Departments?  I didn't test that) if needed.

It there a way to link numerous Vacation Payable accounts to track this and apply it to the employees when you set them up?

No, there's only one Vacation Payable account that all employees are linked to.

What would be the easiest way to track the VP earned for each employee. Would it be through the Job Category Reports? 

That is another way, that I had not thought of.    Job Categories are separate from Expense Groups, so you could do either / both.

I hope that helps, please post back!
