A large catalogue is complex for more than product count. Variants, customer pricing, warehouses, search and checkout rules matter. PrestaShop, Magento Open Source and Adobe Commerce differ in capabilities and terms. Selection requires checking the exact edition, components and complete sales workflow.
Describe complexity through product examples
Prepare representative items: simple products, bundles, variants, units or other required models. Record search attributes and order data. Editors and integrations should unambiguously identify what is being sold.
For example, a customer selects a bundle while stock is tracked by component. Validate support for that rule and its accounting link. A general unlimited-catalogue claim cannot replace this assessment.
Compare editions and dependencies
Capabilities depend on product, edition, modules and customisations. Verify group pricing, organisations, warehouses, currencies and approval workflows. Do not automatically attribute a paid edition’s feature to an open edition or another platform.
Include infrastructure, components, licences and maintenance in estimates. Open source does not mean maintenance is free. Owners need a clear inventory and responsibility boundaries for core, theme and external integration updates.
Test integration and search with realistic data
Agree product, price, inventory and order ownership. Bulk updates must not prevent required purchases or leave contradictory catalogue state. Retries and untransferred records need managed handling and reconciliation.
Test search, filters and data indexing with representative data and load. Caching must account for personal pricing and permissions. Shared page caches must not expose another customer’s terms.
Accept the store and its change plan
Test group-specific orders, shipping, payment, returns and accounting. Separately check URLs, canonicals, languages and filter indexing policies. Migration needs old URL mapping rather than redirecting every product to the homepage.
Test updates on a copy with relevant data and scenarios first. Hand over recovery procedures, components and known limitations. A large store must remain manageable as catalogue, rules and support staff change after launch.
