Product Cost price written in the price_unit is always untaxed. (Meaning more time spent on manual calculation and more chances of errors)

Impacted versions:

• 7.0 and above

Steps to reproduce:

1. Create a product with supplier_taxes_id = Tax 18%, and price_include = True
2. Buy this product with purchase order: Write in unit_price = 11.8. Untaxed amount then = 10. As a result, product cost price will be updated to: 10.
3. Then buy this product again through purchase order. When you choose product_id of this product, the unit_price will be automatically written: 10. But user usually buys this product at 11.8 which is tax included amount.

Current Behaviour:

When user frequently buys one product with tax included price, she/he gets automatically untaxed amount written in unit_price of purchase order line. This means that each time user buys this product, she/he has to correct the price there manually and write the tax included amount. This increases time spent on purchase order and increases of chances of errors because of manual calculations made by user to write the correct tax included price.

Expected Behaviour:

If a product, in accounting tab, has supplier_taxes_id filled with Tax which is included in price, then: In Purchase order line, unit_price field should show Tax Included amount in product unit price. So that user will not calculate taxed amount manually to write there because this is the field where user should write tax included amount if a product has taxes included in Price.

Result and Benefits

Less time spent on price calculations in Purchase Order and less chances of Errors in Calculations.
