AR - Provide Service for Building that changes Property Management Company

We provide a service to buildings - they change Property Management Company - my thought was to create Sage Property Management Company type file.  Under Contact info, enter building name - with current Property Management Company name - and details applicable to building.  Ship To info could contain info related to Property Management Company.

Testing - I created a new file using this logic - but when trying to produce detailed Customer AR report - the invoices are listed, but not according to Property Management Company.

Our invoices are paid by Property Management Company while they are managing the building - but that changes.

Using the software, please let me know how I should be doing this as so far - it is not working.

Thank you so much

And trying to select the Category and Subcategory below is not user friendly - did I find the right one?
