NolaPro is a free, web-based Business Management & Accounting Suite. It includes all standard accounting modules as well as order entry, inventory tracking, full payroll services, and plug-ins such as point-of-sale, a business-to-business web portal, and an e-commerce shopping cart. You'll find its interface very flexible with user-customizable options for colors, icon sets, and menu displays. The software also allows multiple sets of books for different companies, unlimited simultaneous users, and no data restrictions. Administrators will be pleased with its high level of security for regulating user permissions (read, write, setup) by particular module area.
