Not sure what your problem is but here is a basic explanation of each
the first three below deal with when you sell something:
Sales order – your customer is placing an order with you
sales invoice – the invoice you prepare for your customer
Bill of lading – document issued by the carrier (ups, fedex, common carrier) acknowledging that they received goods that you are shipping out)
Shipping documents – documents that you shipped an item you sold
The next three are when you are purchasing something”
purchase order – you are ordering from your vendor
Receiving reports – documents what goods you have received on a purchase order
purchase invoice – the invoice you receive from your vendor after receiving your goods
Materials requisitions are used if you are manufacturing something and you need to requisition materials from raw materials inventory to build a product.
Hope this helps,, Can you explain a bit more the problem you are having?
