phpMoneyBooks is a PHP/MySQL program that aims to be a Web-based QuickBooks replacement. It can manage bank accounts and check registries; manage customers and create statement charges; print statements to bill customers; and display profit and loss reports. The design is modular so that features can be added by any PHP/MySQL developer. With new modules, you can direct the user to a URL. Clients can log in and check their own bills and pay online, create memorized billing cycles with Auto Billing (good for recurring billing), and more.
