If a webmaster reads the documentation carefully and configures the software properly, he will have no problem starting up a shop with several thousand products.
Quick.Cart is fast because it stores data in RAM. Several years ago you could get only 16 MB of RAM on a server and it was difficult to have a shop with more than 2000 products. Now 128 MB of RAM is a server standard. With PrestaShop or OpenCart it's all good until too many customers visits your shop.

Nonsense! Our program is more efficient » than other programs. Quick.Cart.Ext offers functions, which are required in large shops, such as SEO mechanisms, access to administration panel for many admins, user login, ordering various versions of a product, control over stock volumes, integration with payment services, price comparison services, newsletter, polls, news and many others.
A great proposition for those who offer not just small websites, but are looking for tools that are fast, stable, easy to modify and most of all safe. - review by Jarosław Migoń »

A customer came to me about updating old Quick.Cart.Ext v3.5 shop to the v6.5 version. The customer wasn't complaining about anything, but admitted to having been "cheating on" Quick.Cart for the last half year and using PrestaShop. This experience allowed him to decide to go back to Quick.Cart.Ext.Review by a partner Zbigniew Sztandera from StudioStrona.pl
