Hi khansalim,
An e-commerce platform typically refers to a series of solutions which enables online merchants to build what will effectively be their store in cyberspace. A quick internet search should pull up a wealth of options with varying complexity, feature sets and of course, price points.
Given the vast amount of options available out there, I would recommend doing some research and establishing what features in a platform you need and what you can do without. With this in mind, your search for one which fits your budget will become significantly easier. With a little luck, someone in the community might even provide you with a list of recommended platforms. 🙂
Good luck!
-Ivan
