What we build
From the backend that runs the business to the storefront customers buy from and the app they hold in their hand , Tecziq builds the full stack online retailers actually run on, not just one slice of it.

Custom backend systems behind the storefront , B2B ordering portals, inventory and EDI integrations, and bespoke applications that connect your ecommerce platform to the rest of your business, not just the platform itself.
40% better EDI efficiency

Multi-store architectures, B2B wholesale layers, and custom configurators built on the platform , for retailers who need more than a theme and a standard setup.
5-year tech partner

Native and hybrid apps for whichever platform you're already running , Prestashop, WooCommerce, OpenCart, Shopify, or BigCommerce , built by the same team that built the storefront underneath it.
