E-commerce agency
An e-commerce technical team, with no middleman between you and the code.
Store builds, migrations, audits, maintenance, custom modules. You talk to the people who write the code, on the platforms we work with every day.
An e-commerce agency first needs to know how to keep a store running: absorb a major update, handle a traffic peak, connect an ERP without losing an order. DataFirefly is a technical agency. We have run our own online stores for more than ten years and we publish 373 modules for PrestaShop, WooCommerce and Shopware. You work directly with the people who design and develop, with no account manager between you and the code.
What we do
Store builds
From scoping to go-live, on the platform that suits your business: PrestaShop, WordPress / WooCommerce, Shopware or Shopify.
Platform or version migration
Products, customers, orders, URLs and redirects carried over so you keep the search rankings you have built. Dedicated pages: PrestaShop 8 to 9, Shopify to WooCommerce, Magento to Shopware.
Audit and maintenance
An outside look at the code, modules, security and performance, followed by monthly support: PrestaShop audit, WooCommerce audit, Shopware audit and maintenance on each platform.
Custom development and connectors
The module, plugin or ERP connector your store is missing: PrestaShop, WooCommerce, Shopware, or a multi-platform project.
Tracking, consent and visibility
