You can use an off-the-shelf eCommerce solution like Shopify, which makes building an online store a quick and easy process. However, it will also mean less customization, as you will need to choose from an existing pool of themes and tools provided by the platform. If you opt to run a dropshipping business, eCommerce solutions like Oberlo will allow you to get the store off the ground and start selling in as little as few hours.
BigCommerce is most easily compared to Shopify. Both platforms offer a similar experience when building an ecommerce platform. Like Shopify, BigCommerce offers a range of prices and packages tailored to different types of businesses. The platform is highly customizable if you are comfortable with some light coding. It is also possible to use themes and templates to build your website, but some of these will come at an additional cost.
