Which is better for an online store: open-source or SaaS?
This all depends on the size of the project. If you’re considering selling a few items and running a relatively small online store, SaaS is perhaps the best way to go. By choosing SaaS, you’ll have more time to focus on your business, as functionality will be pre-defined and provided to you as a service.
However, if you are considering running an online store which will grow over time, an open-source platform, such as Magento, is a better choice.
Open-source platforms will enable you to easily scale, extend and customize your online stores, without migrating to an entirely different platform, or worse, paying subscription fees for additional functionality.
