Microsoft Dynamics GP is organized in Series, each of which contains several modules. The typical Series are Financial, Sales, Purchasing, Inventory, Project, Payroll, Manufacturing, Company and System. The last two contain all the necessary modules to configure various company-wide and system-wide options. Each Series involves a full cycle of transactions for that particular Series, for example, the Sales Series implements the Quote to Cash process. In addition to the typical "out-of-the-box" modules, Microsoft's community of Independent Software Vendors (ISV) has developed a number of add-ons and verticals, all generally referred to as Third Party applications, which complement or enhance the existing functionality of the application. Some of these are also written in Dexterity, and so look and function in the same way as Dynamics GP standard modules.
