It is easier and cheaper than ever before to add functionality to your website, whether that is a shop, a ‘click & collect’ facility or an appointment booking system, it is becoming mainstream and painless.
WordPress, WooCommerce, Shopify
WordPress linked to WooCommerce is a free solution which is widely used or some perfer a paid solution like Shopify. Which platform you use may be dictated by your POS (if you have a physical shop which needs to be linked into your online shop).
eBay, Etsy, Social Media
In fact you no longer need a website at all to be able to sell. There are many other options which may be better suited to your needs and budget. I can help you to set up an eBay shop, an Etsy shop, or selling through Facebook or Instagram.
