Ecommerce is the act of selling products are services online. There are many ways that this can be achieved like building a bespoke website or using an ecommerce system such as WooCommerce.
We have designed and developed many WooCommerce ecommerce stores over the years for clients as it gives them features they need out-of-the-box such as coupon codes, reports and sales whilst also being flexible enough to let us develop custom functionality that the business may need.
There’s a myth in our industry that WordPress/WooCommerce isn’t a good choice for powering a “serious” online business – from our experience though, this is just bad education. When configured properly, WordPress and WooCommerce is more than adequate for many small to medium businesses.
