Still reviewing the PoS Module and I discovered that when searching for a product to list on the invoice, no alert is shown when the item is not found on the database.
This could be a problem where the cashier is scanning many items for sale and the “not found” item is the last to be scanned. The cashier may not know that this item is not listed and go ahead to take payment.
I believe there needs to be an alert/pop up that the cashier must dismiss if item searched/scanned is not on the database. This will prevent errors leading to loss of goods.
