I'm trying to record purchases that are made within taxes and reflects over product costs.
I create the purchase order including the product and the tax correctly. I receive the goods, validate the entry, and correctly record the bill for the vendor. However, when I go to the inventory to check the product cost, it's not reflected by the tax amount.
If I check the inventory before create the vendor bill, the cost is correct. But when the bill with the tax details are created, the cost of the product changes by minus the tax amount.

The product is configured with AVCO and automatic calculation.

Example:
I buy 100 products at 10.00 each (total of 1000.00 excluding taxes)
The tax is 25.5%, the total cost of the purchase is 1255.00

When I complete the process that I mentioned above, upon checking the inventory of the product that came in and the cost, the quantity is correct, however, the unit cost is 10.00, when it should actually be 12.55. (it's the first entry of this product)

The tax is configured with the following options:
Type: Purchases
Scope: Goods
Included in price: Standard (blank)
Affects subsequent tax base: unchecked
