E-commerce technical architecture: choosing the right platform

SaaS or open-source: the choice depends on your revenue, the complexity of your business and your in-house technical capacity.

The foundation of all your sales flows

Your e-commerce platform carries the cart, payment, stock synchronization and customer data collection. A poor architecture becomes very expensive to restructure once volume is established.

The choice will determine your flexibility, your dependence on a provider, your costs and your ability to integrate your business tools.

SaaS: speed and predictability

Shopify, PrestaShop Cloud or BigCommerce delegate technical maintenance and let you go live in a few days, with a predictable monthly cost and a rich ecosystem of extensions.

The trade-off is dependence: you control neither future pricing nor the depth of customization of the application flow.

Open-source: control and fixed costs

Magento, WooCommerce or PrestaShop offer total customization freedom and fixed costs that become advantageous at high volume, but require in-house or outsourced technical skills.

You become responsible for security updates, backups and server availability.

Choose based on your actual situation

Below 500k to 1M euros of revenue with no technical team, SaaS remains the safest choice. Between 1 and 5M, the decision mostly depends on business complexity and required integrations.

Always test before investing: open a free trial and live with it for a few weeks rather than deciding from a comparison table alone.
