The bigger picture: E-commerce

Online selling in the UAE and GCC is growing fast on Amazon.ae, Noon, Shopify and Salla. Margins are thin, so knowing your real costs, fees and conversion numbers is the difference between growing and quietly losing money.

What's changing: Marketplaces and ad platforms keep raising fees and ad costs, so sellers are focusing more on profit per order, repeat customers and their own stores rather than revenue alone.
