B2B eCommerce is not B2C with a bulk order button. We've seen that mistake kill more launches than any technical issue ever has.
Most B2B failures come down to one thing ? the store was built for how the business wanted to sell, not how their buyers actually buy.
B2B buyers expect account-specific pricing, custom catalogs, quick reorder, net payment terms, and approval workflows. If your store can't do that out of the box, they'll just pick up the phone instead. And you've lost the whole point.

A few patterns we've seen repeatedly:
? Launching without ERP integration means your sales reps are still manually processing orders. You've added a storefront but removed nothing from the workload.
? Ignoring the procurement workflow. B2B buyers often need PO numbers, multi-user accounts, and approval steps before checkout. Miss this and adoption tanks.
? Treating it like a one-time project. B2B eCommerce needs ongoing iteration based on how your buyers actually use it.

The brands that get it right treat the ERP integration and buyer experience as equally important as the storefront itself.
If you're planning a B2B launch or wondering why your current one isn't gaining traction, happy to share what's worked ?
