What does the company do well? 3Dcart is a solid ecommerce platform that's reliable and easy to use. They have modern, responsive templates and it's relatively simple to configure the online store for your needs. Although it has a good selection of 3rd party add-ons (or apps) like most ecommerce platforms do, 3Dcart has a lot more built-in to it's system than most others. Customer service is helpful and responsive.
What does the company not do well? A little buggy here and there, occasionally causing some frustration. Sometimes it's a function of having a lot of options and sometimes there are some conflicts - such as shipping options not working properly. The back-end admin occasionally reverts back to their old system from several years ago - so there are some ghosts in the system, but no major consequences.
What about the company do you wish you had known before purchasing? Not much, it's a good company that has expertise and has been around a while and offers a good ecommerce platform. There are some limitations in the product options/configurability - which is only important if you want to have more customization options for your products, which not everyone does.
