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](https://www.datafirefly.com/en/expertise/prestashop-store-creation/), [WordPress / WooCommerce](https://www.datafirefly.com/en/expertise/woocommerce-store-creation/), [Shopware](https://www.datafirefly.com/en/expertise/shopware-store-creation/) or [Shopify](https://www.datafirefly.com/en/expertise/shopify-store-creation/).

### 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](https://www.datafirefly.com/en/expertise/prestashop-8-to-9-migration/), [Shopify to WooCommerce](https://www.datafirefly.com/en/expertise/shopify-to-woocommerce-migration/), [Magento to Shopware](https://www.datafirefly.com/en/expertise/magento-to-shopware-migration/).

### Audit and maintenance

An outside look at the code, modules, security and performance, followed by monthly support: [PrestaShop audit](https://www.datafirefly.com/en/expertise/prestashop-audit/), [WooCommerce audit](https://www.datafirefly.com/en/expertise/woocommerce-audit/), [Shopware audit](https://www.datafirefly.com/en/expertise/shopware-audit/) and maintenance on each platform.

### Custom development and connectors

The module, plugin or ERP connector your store is missing: [PrestaShop](https://www.datafirefly.com/en/expertise/prestashop-module-developer/), [WooCommerce](https://www.datafirefly.com/en/expertise/woocommerce-extension-developer/), [Shopware](https://www.datafirefly.com/en/expertise/shopware-plugin-developer/), or a [multi-platform project](https://www.datafirefly.com/en/custom-module/).

### Tracking, consent and visibility

Server-side tracking, Consent Mode, attribution, technical SEO and visibility in answer engines such as ChatGPT and Perplexity. See our [AEO and llms.txt for e-commerce](https://www.datafirefly.com/en/expertise/answer-engine-optimization-ecommerce/) page.

## How we work

- **A written scope and a fixed price** before we start, with a fixed quote within 24h of the scoping call.
- **One technical contact** from the first call through to maintenance.
- **A staging environment** to approve each delivery before it goes live.
- **You own the code and the access credentials**, with no hidden licence and no commission on your sales.
- **Twelve months of compatibility updates** on everything we deliver.
