I'm not trying to split a new hair here, but what constitutes "purchased" for the purposes of credits such as MRc2? Our projects are all government buildings with government tenants and when we "purchase" something, we order it and don't typically provide payment until after the item is received on-site.

So at what point do the MRc2-compliant durable goods fall under the term of being "purchased?" When they're ordered? When they are received and installed on-site (my inclination)? Or when the vendor/contractor received payment (most typically after the installation or reception of the product)? We want to avoid a situation in which we are provided tenant info on an item that is subsequently cancelled or refused on delivery or returned.
