For what it's worth, I can't offer the QuickBooks payment option to our members (customers) unless the payment fees can be added to the invoice should they choose to pay using your payment method. I can't just add the fees to the invoice because some folks will be mailing checks to us and shouldn't have to pay a fee. When I asked about this a year ago, I was told you would be adding this feature but it still is not offered from what I can tell
