Showers Pass review for QuickBooks Online

We recently installed this for our main store. Tech support started really well, but we soon hit the limits of their or their Bot's capabilities. We, like many stores, have D2C, B2B, and POS customers. The app is not capable of handling all three. You have to choose one which totally messes up your accounting. In today's world, how many stores operate on a single channel? We have tried to escalate the issue and have been given the runaround for two weeks now.
