I fully realize this is an opportunistic reply but I sincerely think it could be benefit QuickBooks Commerce customers and Intuit. We've been working with QuickBooks since 2016 and we were part of their developer success program (made for well designed apps). Erplain is a B2B Sales and Inventory software made for small business (1-20 employees), and we are priced accordingly (starting at $89 with our B2B Store). We are fully integrated with QuickBooks Online, so you can remain in the QuickBooks ecosystem. We do offer a B2B ecommerce portal called the B2B Store. Please check us out in the QuickBooks app store and let us know if you have any questions.
