Shift4Shop's B2B eCommerce plan includes the full suite of features from Shift4Shop Pro, our highest-tier small business plan, plus additional B2B-specific features. The extra B2B features normally carry an additional cost in the Shift4Shop App store but are included in the B2B eCommerce plan to provide more tools to the businesses that need them most. Growing B2B businesses may later transition upward to our Enterprise plans without losing the extra B2B features or paying the Enterprise setup fee.
