Copy and paste updated information from a Workbook to the same workbook

Hi guys,
My situation is this:
I have information about payments. The main file entitled "Main File" holds all records needed.
This file is sent to managers in every company E.g: Verizon and the manager sends back the same Main File filling only payments regarding Verizon(everything else is left blank) - File entitled "Manager Sends".
I want this to be automatically inserted in the main file instead of me having to copy and paste the information based on the ID of the employee.

I would appreciate any help guys!

Thanks and have a great day

In this example, only the Verizon manager sent the information
