Hello,

Promos are considered discount, but they just change the price.

The sale details display the discount and receipt view is compact so that doesn’t display.

Thank you

Sorry, I did not understand your answer I want to show the price of the products that have promotional offers I want to show the basic price before the offer and the price after the offer in the invoice or show the amount of the discount so that the customer knows that I have made a discount for him

Hello,

The promotions change the products price to promotional price. This is not considered a discount.

Instead of promotion, you can apply the discount on sale.

Thank you
