- Single-dashboard catalog management for core channels (Shopify, Amazon, Walmart).
- Custom product attribute transformation and feed rules engines.
- Basic multi-channel inventory auto-sync and stock deduction.
- Canonical order consolidation into a single web portal.
- Automated price updates and rule-based repricing triggers.
what you lose
- Out-of-the-box integration with over 420 international marketplaces and retail media networks.
- Dedicated enterprise onboarding services, technical account management, and SLA guarantees.
- Built-in enterprise dropship network and vendor management machinery.
- RithumIQ AI-powered retail media ad bidding and automated algorithmic repricing.
- Automated handling of channel tax collection, nexus reporting, and local regulatory updates.

MultichannelWorks
Building a centralized SKU database and webhook receiver is easy, but maintaining native adapters for Amazon SP-API, eBay REST, Walmart, and Shopify is an ongoing engineering tax. Marketplace API deprecations, OAuth credential management, and complex category mappings make custom solutions fragile.
