- What’s the best way to secure transactions and prevent fraud?
- How can you scale your platform without constant performance issues?
- What tools ensure smooth inventory and order management without turning into a logistical nightmare?
An e-commerce platform isn’t just about listing products and hoping for sales—it’s a complex ecosystem requiring well-planned functional and non-functional requirements. From an intuitive user interface and secure payment gateway to reliable performance and scalability, every element contributes to a store’s success.
This guide breaks down all the essential e-commerce system requirements—helping you build an online store that’s not only efficient and secure but also delivers an outstanding customer experience. Let’s dive in!
