The xTuple ERP applications all started with OpenMFG, our original award-winning ERP suite first released in 2002. Today, the OpenMFG Edition of xTuple ERP is our premium commercial offering, recommended for manufacturing companies in both discrete and batch process production; make to order, make to stock, or mixed-mode; even job shops and engineer-to-order.
	The PostBooks Edition of xTuple ERP is our entry-level offering, available completely free and open source, and suitable for small businesses of all kinds. It includes full financials; robust CRM; Sales and Purchasing; financial and ad-hoc reporting; and lightweight inventory, manufacturing and distribution.
	xTuple ERP Standard Edition, our newest product, is a midrange commercial offering, which adds advanced inventory control, warehousing, and other features to the core package. It's a great option for distributors, retailers, light manufacturers, and anyone else who would prefer commercially licensed software.

All three editions are built on the same code base; in fact, the client software is exactly the same (so upgrading from one to another is a snap!) All three run equally well on Windows, Linux, and Mac - and are fully internationalized (multi-currency, support for multiple tax structures, and multilingual translation packs maintained by our global community). All three contain a full copy of OpenRPT, the open source report writer also created and maintained by xTuple.

And whether it's the free PostBooks Edition or the commercially licensed Standard or OpenMFG Editions, you get the full application source code (client and server). You can participate in the ongoing improvement and development of the software as much as you like. Best of all, xTuple will manage that multi-product community development process so that all companies - regardless of how technical they might be - can benefit from the open source way of doing things.
