Right now (march 2019), an inventory item based discount works correctly in tickets, but incorrectly in invoices. tickets correctly show a decimal percentage discount (ie, a discount of 11.3% - a ticket with $100 worth of charges would be discounted by $11.30 to $88.70). Once that ticket is used to create an invoice, the discount percentage is automatically rounded down to a whole number (ie, the 11.3% listed above becomes an 11% discount on the invoice, so $100 worth of charges would be discounted by $11.00 to $89.00).
