Existing website upgrade to ecommerce

Hi! I have a question about updating an existing page in the future. I want to create a webflow page that will show my products. At the moment, I do not need the option to sell products via website, and thus I don’t need the e-commerce plan, but I do not exclude this possibility in the future. If I buy a regular CMS plan now, can I upgrade my website to an ecommerce in the future or should I buy an ecommerce plan right away?
