This manufacturing firm only has three retail products for sale and wanted to start selling online with a low startup cost. I configured a PHP shopping cart script for them and set it up to calculate UPS shipping, feed to Froogle, and to use Paypal for payment processing. The whole project was relatively inexpensive and they are just paying for basic hosting on a Linux/Apache host. It suits their needs, but I'm wondering if it looks unprofessional compared to larger businesses with more high-end e-commerce applications. Please give me opinions and ideas.
