OpenCart has the same level of customisation through its design themes and templates, giving the option to make adjustments to every element of the design and aesthetic of your website. With over 1,600 templates to choose from OpenCart enables the expansion of your store and website capabilities. However, this would require a level of HTML, CSS or PHP coding skill.
Shopify, on the other hand, offers the ultimate user-friendly experience. Although the themes and the level of customisation are not quite on par with OpenCart, Shopify allows the simple yet effective customisation of colours, fonts and so on. Additionally, the themes offered are industry-specific, ensuring you can truly pick the one that complements your business with the most efficient features.
OpenCart and Shopify both perform equally in this aspect. While OpenCart offers complete customisation it does require a level of expertise and coding knowledge, Shopify provides flexibility through the ease of its theme editor but doesn’t have quite the same range of customisability.
