We need a new option in the inventory purchases module to manage Non-Discountable VAT. When the VAT of a purchase is not recoverable (it is not a discountable VAT), you must be able to select that VAT to be incorporated directly into the cost of the inventory, instead of being recorded as a debit to the Discountable VAT account. This is essential for the system to correctly calculate the cost of sale (COGS) and to be able to directly apply law withholding.
