Internal service requisitions

 Hello,

Is there a way with Order management to treat services?

For example, we would like to manage requisitions for moving service, or other internal professionnal services.  As we do not have many types, is it possible to manage them using iProcurement and OM?

We were thinking of creating some inventory items with non-stockable properties. 

Is it possible?   Do you have other way (witm OM) ?  Without OM?

We also use products (inventory items) that we would like to combine to service lines.

Thanks!
