inVINCEable

I am trying to start this online ordering system for a business. Basically identical to how the pizza-hut and dominos online ordering! How do I go about that? Do I learn how to write code? Buy software for my business? And if I do pursue software from another company, if the business becomes bigger, will that limit the rights that's I have for it to be mine? Please help. I'm new to this and really want to learn the ropes here!
