The objective is to have two prices for a product: one for trading with customers and another for internal use within a group of companies, which should not include any profit or mark-up. If customers want to calculate the profit made by selling within the group, they can look for a report of invoices and adjust accordingly. Intercompany transactions need to be done at the previously defined cost price or at the lower value between the two legal entities. The proposed solution is to add a new field called "Group Price" that can be used for intercompany transactions and stock valuation, while the original price is used for other commercial transactions. This new field can be added as a new column on the Item Price form or as a new field on the item card.
