Magento’s ability to scale allows shops with only a few products and simple needs to easily expand to tens of thousands of products and complex custom behavior without changing platforms. It offers a variety of plug-ins and themes which can easily enhance a customer’s experience. There are a lot of aspects to the online store which need to be configured, and how well that is accomplished is often dependent on business acumen. When it comes to custom functionality, however, that is where more complex programming is required.
Magento is designed to be utilized as an application by someone who isn’t a developer. The Magento community is extremely large and very helpful. However, at some point the average person is going to hit a wall.
There are a number of reasons why developers are called upon to adjust a Magento website. It is a very robust system even at its most basic, more so even than a Drupal site (and Drupal is no lightweight). Once you begin to integrate with other systems, or introduce tens of thousands of products, businesses often need the assistance of experienced developers. The functionality can be changed only up to a point; beyond that, it needs to be customized by an expert who really understands Magento, and follows best practices.
Experienced developers will also tell you that speed is of the essence in ecommerce. No one wants to have to wait for systems to reload when you’re doing a lot of online shopping. With such a robust list of features native to the application, strains can be put on your server .
