I want to adjust this point of sale (see attached file) to my needs. This is a improved version which includes the possibility of select a customer in an order and see the product id besides the product price. And what I need in addition is:
1.- Change that product id for the product stock.
2.- Apply discount in total price. In default POS you can apply discount per product but not in the total of the order.
3.- Individual taxes. I need to see in the ticket what percentage of taxes is applied to each product (ex. 21% 10% 4%) and calculate their amount. I don't need to see "with a discount of..." so this could be erased and in that second line put the taxes of every product.
4.- Directly invoicing. Add a button for invoice the order and print it directly from the pos. In the ticket printing window.
Please only people with experience in OpenERP. Thank you.
