Catalogue & checkout
OXID eSales
Customer-specific price lists, tiers and discount logic are evidenced for trade customers, together with quick order by article number, quotes, approval workflows and buyer management, and five payment providers are named as official modules. We found no public information on a variant matrix, product bundles, guest checkout, or invoice purchase and direct debit named for German buyers, so merchandising depth beyond trade pricing stays unproven.
PrestaShop
The captured pages show a native one-page checkout bundled with version 9.2 plus developer guidance for making modules and themes compatible with it — a real conversion feature. Beyond that we found no public information on variants, bundles, tiered or customer-group pricing, payment methods, or net-price display for trade customers, so I cannot confirm this shop meets a business buyer at checkout.
