The best Wholesale for WooCommerce alternative depends on how much of a B2B workflow you actually need. If you also need quote requests, payment terms, and tier reporting working as one connected system rather than a stack of separate purchases, you are looking at a scope-and-integration problem rather than a quality problem. A store owner told me they had wholesale sorted, because they had bought a wholesale plugin. Two months later they emailed again asking how to offer NET 30, because their biggest buyer had requested it. The capability technically existed, but only as a basic manual payment method or a separate paid extension they had not purchased yet.
