When a customer makes a return partial or full and the invoice still has not been created the order can be taken and modify the amounts to adjust it to the final total. If the returned products are in good condition there is nothing else to do because deleting or modifying a shipped order the products will return to the inventory.
Selection of products to return
If the invoice was already created or you simply want to make a partial return you may do as follows
Sale > Returns > Choose the client - the list of products that appear in that moment are only the ones that have been shipped.
When the item is selected it will show the orders that have the quantities sold, pick the right order to have the return and then you should enter the amount to return as it is done when making a basket. The maximum quantity to return is limited to the shipping delivered. Though it does not matter that the items are in good condition or not.
When you finish entering all of the products to return, you should tap on the cart as it is done on sales.
Products that cannot be sold again
On the basket of return is shown the total amount and in yellow the "good" ones that would return to the inventory, the others are not available for sale.
End return
In the final view, you may modify additional information such as the date of the return, the amount that should be charged for accepting returns and partial or total money that you want to return. If you do not enter an amount to return now the total on the return will be a credit on the customer so that it can be applied subsequently to the payment of another order.
