In a plan of hiring employees around 15-20 currently, I need an update on what all the documents i need to get ready before i Hire New Employees & Before Getting into business with clients. As due to current situation i am not in a position yo hire a HR, But it would be very helpful if anyone could help me related with what all documents i need from Joining Letters, Re leaving Letter, Attendance, Salary Slip, Agreements, Clients Agreements, Ect...,
I would appreciate a quick response also would be happy if i find the Attachments in the same.
