Wholesale and B2B selling on Magento 2 breaks the moment every buyer needs a different number. Magento Open Source gives you tier prices and customer groups, and Adobe Commerce adds Shared Catalogs and Company Accounts — but neither covers true per-customer contract pricing, conditional price hiding, and catalog visibility rules in one coherent, upgrade-safe package.

This is a build-to-order extension. ECOSIRE engineers it as a proper module under app/code/Ecosire/B2bPricingCatalog, wires it into your store through di.xml plugins and event observers rather than core edits, then installs and supports it on your environment. Nothing is overwritten; the module ships its own etc/, Setup data patches, service contracts, and admin ACL.

Pricing resolution is layered: a catalog_product_get_final_price observer and a price-model plugin apply per-customer overrides first, then per-group, then tier/contract bands, with correct cart, GraphQL and REST price parity so headless storefronts and the Luma/Hyvä frontend agree. Hide-price and login-to-see-price are enforced server-side via a block plugin and layout handle — not just CSS — so prices and add-to-cart are genuinely unavailable to unauthorized visitors. Restricted catalog visibility filters category and search collections per customer group through a collection plugin, keeping hidden SKUs out of listings, sitemaps and APIs.

Bulk price import runs through a CSV/queue console command and admin grid, with a cron consumer for large books. You get admin ACL, system configuration, logging, and a clean uninstall path. We scope your exact rules first, build against your Magento version (2.4.6–2.4.8, Open Source or Adobe Commerce), deliver to staging, and hand over with documentation.
