Invoicing I send invoices on the 1st and 15th of every month. I send invoices electronically through QuickBooks. This does NOT mean you have to pay me through QuickBooks. You MUST pay within 30 days of receipt in order to avoid late fees. How to Pay QuickBooks You will receive a QuickBooks invoice via e-mail. This invoice gives you the option to pay through QuickBooks using direct bank transfer or a credit card.
