Invoicing needs to have an accounts receivable credit and debit feature for restaurants. I have guests that house charge. I tender the check to house charge payment key (accts. rec.)and then invoice the department to be paid. When they pay it comes back as a sale again. I understand the system is closing the check when I tender to house charge and then when I invoice its creating the sale again. Under this method when it then gets paid it comes in as a sale again. In other words its a double payment. I need the sale to be on the books the day it occurred not when its paid. With this invoicing system the sale occurs when the invoice is paid. How do you compare your sales from one year to the next? This needs to be fixed or an option for it not to be this way.
