Catalogue & checkout
JTL-Shop
The only evidenced commerce surface is payment breadth ("Integrationen zu allen beliebigen Payment-Anbietern") plus a 30-marketplace and 24/7 repricing engine; variants, bundles, tiered pricing, guest checkout, promotions rules and checkout customisation appear nowhere on this sheet, so the catalogue itself is essentially unevidenced.

Variants are properly modelled — parent-child inheritance, a configurator assembled for each variant product, hierarchical categories — and payments sit on a documented handler architecture with synchronous and asynchronous flows, PayPal the one provider named. We found no public information on bundles, tiered pricing, guest checkout, or German-standard payment methods such as invoice and direct debit; customer-specific prices appear only in the Beyond tier. The checkout is clearly extendable, but the conversion machinery itself is not evidenced.
