There are also free osCommerce templates available on this website.

Familiarizing yourself with osCommerce.

The first thing you should do when thinking about starting up an online store is make a list of all of your needs. What products or services are you going to sell? How do you want to process payments? How much time do you have to set up and maintain an online store? What is your budget? In addition to selling products, what else do you want your store to do? Newsletters? Register customer accounts? Manage stock levels? Allow for customers to review products? Fully understanding your needs before choosing the e-commerce platform that's right for you will help ensure you're getting the functionality you need. There are a lot of good (and free) e-commerce platforms, so you should absolutely investigate all of them before committing to use a specific one. If you want to learn more about osCommerce, a good starting point is the osCommerce website.

If you're left with any questions or concerns, you may want to visit the osCommerce community support forum to meet some of the other osCommerce users to discuss your individual needs and concerns.

There's also a demo installation of osCommerce on the osCommerce website that you may want to check out. Keep in mind that the core-functionality is what's more important -- the look and feel of the website can be completely customized to appear however you want it using any of the widely available free osCommerce templates.

osCommerce requirements.

As already mentioned, osCommerce is completely free to use. It's pretty easy to set up and the server requirements are within the bounds of what your average hosting service provider offers. You'll need a domain name ( and a hosting account that supports PHP and MySQL, and if you're looking to process credit cards directly through your site you'll need a SSL certificate (for encrypting your customers' sensitive data).

osCommerce 2.2 vs osCommerce 3

There are currently two version of osCommerce that are used on a regular basis by the community; osCommerce 2.2 and the more-recent osCommerce 3.  Your website's requirements and your own preferences will determine which system is better for you.  osCommerce 3 is newer and has a more advanced, object-oriented coding approach, but it has not been supported by the community in the way 2.2 has, and therefore doesn't yet have as many modules or as much support documentation on the forums.

osCommerce 3 has a template system by default that allows you to manage the look of the website, while osCommerce 2.2 requires that you either edit every individual file or install a template system liks STS (which is what the templates on this website use).  This shouldn't keep you from considering 2.2, however, as installing STS is relatively quick and easy.

If you need help deciding which installation is best for you, you may want to check out the osCommerce forums.

Customizing your osCommerce online store.

While osCommerce is an extremely powerful e-commerce tool with a boat load of available plugins and modules to do just about whatever you want, the appearance of the default osCommerce installation leaves a little bit to be desired. The good news is that's okay -- the look of your osCommerce website can be completely customized using a free osCommerce template. Your store can go from looking amateurish and simplistic to sleek, sexy and professional in minutes, and you'll still retain all of the impressive e-commerce features included in the osCommerce package.
