  3. Headless Database Backend Platform like Firebase
  4. Headless Content Management System CMS
  5. Headless eCommerce system

Our topic of the day is open-source headless eCommerce solutions for building eCommerce web, mobile, and desktop apps.

Developers can benefit greatly from these solutions. They can start building their eCommerce, shopping cart apps, and apps directly without worrying about backend development.

Headless CMS VS headless eCommerce

Headless CMS (Content Management System) solutions, which are designed for building CMS or general-purpose web and mobile apps. However, a headless eCommerce solution aims to aid in building complex eCommerce and digital shops solutions.

What can you do with a headless eCommerce system?

  1. Lower the cost of building an eCommerce system from scratch
  2. Minimize the development time and cost
  3. Provide all API functionalities to build eCommerce and digital shop solutions

Self-hosted Headless eCommerce VS Headless-as-a-Services eCommerce

Many services offer headless eCommerce services for a fee, which may seem cost-effective as they take out the headache of hosting, setup, update, upgrade, and security.

However, an open-source self-hosted headless system can serve furthermore as they allow you to own your data, avoid lock-in, and have better control of the system.

Enterprises can scale and extend your self-hosted thanks to experienced developers. As example, adding another payment gateway, or integrate a 3rd-party service.

Can you use a Headless CMS as a headless eCommerce solution?

Short answer, Yes, it is possible, but at a cost.

A Headless Content Management System (CMS) aids in building rich-content web, mobile or desktop apps.

Using it to build an eCommerce portal or a storefront requires custom setup, custom workflows (products, orders, inventory, shipping, payment), and effort/ time to integrate payment gateways, shipping services, and more.

On the other hand, Headless eCommerce solutions are packed with all infrastructure required for building eCommerce and business solutions. They often have built-in payment gateways and dozens of integration-ready tools.
