Hi,

I've been using OpenCart for my wholesale business but have run into several issues with it, so I'm considering trying out AbanteCart.

I've looked at the demo & browsed the manual but couldn't see the following features. Could someone please advise if the following are possible in AbanteCart? Thanks.

1. Can you add shipping fees after checkout has been completed and then resend the altered invoice?
2. Can you add an individual product code for the same sku numbers?
3. Is there an import/export feature or extension for products and categories from other carts (OpenCart)?
4. Is it possible to modify the CSS file for my theme/store or can you only modify the layout in the dashboard panel?

Thanks for any help & advice.
