We specialise in developing mobile-friendly ("responsive") eCommerce solutions for clients. But this is one area where, sometimes, a native app is not the right solution.
If you think about how potential shoppers find you (on Google rather than the app stores) and that you want them to see your products and check out as quickly and simply as possible, asking them to download your app (they'll probably wait until they are on free WIFI or forget and then they must remember to open it and register) might not be the right solution unless the app can offer something (such as location-services, simplified payment solutions, augmented reality) that a website can not.
That is why we often recommend starting with a mobi-friendly website, which can often be simply converted to an app later on. Our preferred eCommerce platform is Shopify because:
In 2016 we created a separate eCommerce consulting business, eCommerce Experts. In 2017 we became one of Shopify's first partners in South Africa. In 2018 we were officially recognised as a Shopify Expert (you can view our profile on Shopify's site here). We have built more than 60 eCommerce sites on the Shopify platform.
