Can I change a product’s price during a sale?
If a product is already in the basket, but its price needs to be adjusted for the current transaction.
Yes. Select the product in the basket, open the price-editing option ( $ ), enter the required price and confirm the change.
The adjusted price applies only to the current order. It does not permanently change the product’s standard price.
Business Central controlled: Permanent product prices and sales price lists are managed in Business Central. Changing the price in the basket only affects the current POS transaction.
