There are a few things to consider when choosing a platform for your ecommerce store.
First, consider what kind of products you will be selling. If you are selling digital products, you will need a platform that can support digital downloads. If you are selling physical products, you will need a platform that can integrate with a shipping provider.
Second, consider what kind of features you need. Do you need a platform that can support multiple languages and currencies? Do you need a platform that has a built-in blog or forum? Do you need a platform that can support complex product options?
Third, consider your budget. Some platforms are free, while others can cost hundreds or even thousands of dollars per month.
A few popular ecommerce platforms include Shopify, Volusion, and Magento. You can read more about each of these platforms here:
