Chris Kresser: We have switched over to using MD HQ. The advantage to using QuickBooks was that everything was in QuickBooks and we have a large practice, a lot of bookkeeping and accounting, and the value of having everything in QuickBooks easily without having to export reports of transactions from MD HQ and import them into QuickBooks was a big benefit. But there were some downsides to doing it that way. And at some point the downsides began to outweigh the benefits. So now we just use the built-in MD HQ payment system.
