Saving Documents received from Logistics

Saving Documents received from Logistics

Hello,

I'm unsure if this questions is better for Books or Inventory. However here is the problem I have:

We are making a Purchase of goods through Books. The goods are being delivered using 4 trucks in 4 different days. Each trucks come with partial amount of goods And a lot of documents  (Logistics, Customs etc...). When the goods arrives they will be imported as items. We will use certainly Inventory instead of books alone for this.

My question : How and where do you manage all the documents received by all the logistics, linked to this purchase ? Is there a folder, a reference, etc ?
