I am looking to build an e-commerce store that can handle many items (in the thousands) and many categories. I'm looking into Magento and X-cart but don't know which one will be easier to customize the template and the payment processing part. I'd prefer a solution that doesn't use smarty template bc I dont have experience with that. (I'm not sure if Magento/X-cart do).
For the payment processing, I need to be able to disable the built in payment process and write my own code so that I can post the orders to different suppliers depending on the items purchased by the user.
Thanks in advance for any of your input!
