Catalogue & checkout
OXID eSales
Customer-specific price lists, tiered pricing and discount logic are published, with five named payment providers and per-category promotion filters a marketer can build without a developer. But we found no public information on a variant matrix, product bundles, guest checkout or multi-currency — the merchandising core the upper levels are made of — so the pricing engine carries the score, not the catalogue.
PrestaShop
One bright spot in the evidence: PrestaShop 9.2 ships a native One Page Checkout module in the bundle, with developer documentation for making modules and themes checkout-compatible, and payments attach through payment modules in the order commands. Beyond that we found no public information on variants, bundles, tiered pricing, or which payment methods a merchant actually gets at the till.
