At PGS, we make the most of the free open software packages available today. For simple websites, we recommend the WordPress content management system. For sites that require online transactions, we recommend the PrestaShop online store system. WordPress is a content management system (CMS) that grew from its humble roots as a blogging tool. It possesses a rich set of easy to use features for building and managing your web site, and is supported by a massive ecosystem of plugin developers who extend its capabilities further every day. Many of the community produced plugins are free, but a wide selection of premium solutions are also available. PrestaShop is an online store system that offers powerful catalog, payment and shipping management, sales analysis and reporting, SEO (Search Engine Optimization), and even marketing support. Like WordPress, PrestaShop has a large community of add-on developers that offer both free and premium solutions for customers with additional needs.
