Order/Invoice with different customer

[KOO]

Hi all,

I'm facing a little problem and I would be pleased if someone could help me out. Any information, procedure, process etc. would be helpful. Below is my case.

We have a subcontractor working our premises repairing/maintaining different tasks. They update our system by themselves orders and so on. But they are also working for different customer (two companies in the same factory) and the subcontractor wants to update hours of different customer also into our system. Is this possible and if it is, how it is done. What we need also is some procedure how we can track down hours done to us and hours done to the other customer.

Thanks for your help in advance.
