Inventory on hand cost calculation problem

I agree there is the opportunity for Managers to support more advanced relation ships with other organizations such as

  • Organization which is both a customer and supplier
  • Organization with several divisions

The former is discussed with implementation possibilities here

As for the work around

I agree business transactions with another organization can be entered as

  • Sale and a separate purchase transactions or
  • Debit and a separate credit note
  • Both can result it the same net VAT to the tax authority

I do not however believe they are truly equivalent though; as they result in reporting different total sales and total purchases consistent with the different business transactions they are designed to describe. It is for that reason enhanced support of business relationships make more sense to me than enhanced support for a work around.
