An e-commerce engine is the platform and code behind your online store, from storefront to checkout to fulfilment. IQDigital builds on Shopify Plus and WooCommerce, including headless storefronts with Shopify Hydrogen, checkout extensions for upsells and loyalty, ERP and 3PL integrations, and infrastructure ready for flash-sale traffic.
Who it's for
- Brands that have outgrown a default Shopify or WooCommerce theme
- Stores with large catalogues where speed and stability suffer
- Retailers automating fulfilment through ERP and 3PL partners
What is an e-commerce engine?
E-commerce is not just about a checkout button; it is about the entire transaction infrastructure. IQDigital builds high-octane commerce engines on Shopify Plus and WooCommerce that are designed for scale. We move beyond default themes to build custom, headless storefronts that offer unique brand experiences while leveraging the robust backend security and inventory management of established platforms.
How we build on Shopify and WooCommerce
For Shopify, we utilize 'Liquid' for deep customization and 'Hydrogen' for headless React-based frontends. We engineer 'Checkout Extensibility' to add upsells, donations, and loyalty points directly into the checkout flow. For WooCommerce, we optimize the database structure to handle thousands of SKUs without the dreaded 'WordPress bloat' and speed issues.
How we build for conversion and scale
We focus on 'Conversion Architecture.' We implement one-click upsells, bundled product logic, and dynamic pricing rules. We integrate complex ERP and 3PL (Third Party Logistics) systems to automate fulfillment. We ensure your store is not just a catalog, but a high-performance sales machine capable of handling Flash Sale traffic spikes without breaking a sweat.
What's included
- Headless Commerce — Custom frontends on robust backends.
- Checkout Optimization — Mobile-first flow to reduce friction.
- 3PL & ERP Integration — Automating the post-purchase flow.
- High-Concurrency Handling — Infrastructure for flash sales.

Questions about E-commerce Engine
Shopify or WooCommerce?
We build on both: Shopify Plus, customised with Liquid or as a headless React storefront with Hydrogen, and WooCommerce, with a database tuned for large catalogues.
What is headless commerce?
A custom frontend built on top of an established commerce backend. You get a unique brand experience while keeping the platform's security, payments and inventory management.
Can you customise the checkout?
Yes. Checkout extensions add upsells, donations and loyalty points directly in the checkout, along with one-click upsells, bundles and pricing rules.
Will the store cope with a flash sale?
We build for high concurrency so the store can handle the traffic spikes of flash sales and launches.
