Hi Taagen, If you don't already have a website that lists your products: It sounds like what you need is an existing e-commerce program, such as: OsCommerce ZenCart CubeCart If you already have a website that lists your products: If you've already done the legwork of building your website and listing your products, then you can may want to look into using Paypal's Buy Now Buttons. You will however still need to custom build the customer database and the php scripts that interact with it. Recommendation: Of the two options above, I recommend reviewing one of the e-commerce programs listed above. They're free and used by thousands of users on the web.
