This is certainly not in a same league as the more than 24-hour outage in June. But when the customer is at your register with card in hand, waiting to pay and leave the store, or on the phone hoping to move on to something else, two hours can be a long time. (And one client says that QuickBooks invoicing wasn't working either). Let's measure this in terms of Intuit's favorite customer satisfaction metric, the Net Promoter score. One small episode is not going to torpedo a vendor's score. But think about the concept of measuring those customers who would recommend a vendor's products against those who would not. A customer who runs into the inability to pay via whatever means is at risk of becoming someone who says, "Oh, I tried doing business with them. They are awful." The electronic world is more unforgiving than the old manual world.
