Skroutz brings demand — but fails when feeds are unstable, SKUs duplicate and stock is stale. You need a clean catalog, reliable XML/API sync and a checkout that converts.
Combine marketplace sync with product SEO and, where an ERP exists, order sync toward SoftOne or Pegasus.
Stable identifiers, correct Skroutz categories, images/attributes, stock freshness and feed-failure logging.
To build or upgrade a store see E-shops. For complex ERP/marketplace sync see Custom APIs.
