Whenever possible, we let the CM source the parts. The BOM (a simple 
spreadsheet) lists the parts, their values and tolerances. We also specify 
whether substitutes are acceptable. By the way, we recently automated the 
process of creating the BOM using component attributes (this is based on 
Olin's suggestion -- a big thank you!).

When we provide the parts, we enter them into our inventory management 
system (FishBowl) like we would any of the parts we sell or use in-house.

A lot of times we use a hybrid: we let the CM source most of the parts, and 
we provide the rest (programmed PICs, or parts that we can get cheaper than 
the CM).
