Hello,
Thanks for the question. The Launch plan is a minimal plan that is not considered ecommerce ready. If you review the business hosting plans you can see a chart which gives you a suggested list of their capabilities. Anything from the Power level and up are considered ecommerce ready. The Launch plan DOES have the option to support up to 2 MySQL databases, so it is possible to put a small ecommerce shop on the plan, but we definitely suggest starting with the Power plan if your intention is to build a website for ecommerce.
I hope that helps to answer your question! Please let us know if you have any further questions or comments. You can always contact our Sales or Support departments for live assistance - contact information is at the bottom of this page.
Regards,
Arnel C.
