An online store set up of a simple off-the-shelf solution can go live in a couple of weeks, but a bigger, feature-rich platform can take a few months to launch. Keeping in mind the final list of features and design goals, get a specific idea of how much time it will take for your online store to go live before you set a date in your mind. Tip: If someone quotes a really short time while promising an Amazon-like store, it’s probably too good to be true.
