Just recently graduated and now I'm freelancing there is this one job that I'm doing a redesign for a website that has a shop. Never got taught in class on how to manage or go about handling an already made online store. My question is what do I need to learn as soon as possible to make this job successful. Ive been looking online and a lot of sites mention a free or paid shopping cart service. Is that all that I would have to use to be able to place the items and have them work successfully for the company. Please need suggestions/help thank you
