ShopSys vs. a custom build: when a framework pays off

A decision framework for e-shop owners facing the choice of platform.

The question "build on a framework or develop from scratch" comes back with every larger e-commerce project. The answer is not universal, but you can reach it with a few clear questions.

ShopSys is a professional e-commerce framework that gives a fast start and a robust architecture while keeping full control over the code and performance. That is a combination boxed solutions do not offer and a from-scratch build catches up to only at great cost.

A framework pays off when you need non-standard processes, custom integrations and scalability (Docker, Kubernetes, PostgreSQL, RabbitMQ), but do not want to pay for reinventing the basics of an online store.

A custom build from scratch only makes sense when your business model is so specific that you would rewrite the framework anyway. That is rare.

Our recommended approach: start with context. Once we understand your processes, the choice of platform is often obvious — and we can justify it with numbers, not preference.
