Email confirmation of your QuickBooks bill pay should be required by the billing party or paying customer should have the option on every invoice to indicate send me email confirmation and to what email, and this setting should be saved. It is really nasty to the consumer that apparently the billing party can turn off email confirmation. Small sometimes nefarious local businesses is where lots of little petty ripping off takes place by accident or on purpose. Don't you read the news? Get with it QuickBooks, this is the 21st century and consumers need all the real conveniences and protections that come with the modern internet age. And also it seems if one returns again to a bill that has been paid, the system will let you pay it again. Holy s**!! Sigh. And it is ridiculous that I have to make an account to post a suggestion. Overall, QuickBooks and your developer team are being real punks and demonstrating extraordinary laziness and callousness to the consumer. Really?! A reckless Stoneage payment interface from a mega financial company. Sign again.
