|Stable release||4.5.0 / June 9, 2014|
PostBooks is an open source accounting and enterprise resource planning business system geared toward small to medium-sized businesses. It is released under a CPAL license and is thus free software. PostBooks is maintained as an open source project on GitHub but is based on the commercially licensed xTuple ERP system created by xTuple, a private software company based in Norfolk, VA.
The name PostBooks is derived from three aspects of the project. First "Post" alludes to the common concept of posting journals in accounting. Second, the name refers to the project's technological roots as it runs exclusively on the PostgreSQL database. Finally, the name suggests PostBooks as a logical step of progression for businesses that have outgrown the popular QuickBooks small business accounting product by Intuit.
PostBooks is the foundation of the xTuple ERP software solution developed and marketed by the company of the same name beginning in the year 2000. All of the xTuple ERP Editions are targeted toward small to midsize companies. PostBooks is the Free and Open Source Edition; Commercial offerings are the Standard Edition and the Manufacturing Edition.
The first stable release of PostBooks was version 2.2.0 announced in September 2007 when its code was first made publicly available on SourceForge. Since then source code management has been moved to GitHub.
PostBooks is divided into 7 functional modules: Accounting, Sales, CRM, Manufacture, Purchase, Inventory and Products. It supports multi-currency and multi-language capability and is therefore suited for international deployment. All modules are integrated into a single common code base in the client, and reside in a single database schema on the server. The difference between the two is completely managed in the database schema where the OpenMFG database includes additional tables and functions to support larger enterprises.
PostBooks has a mature and established community. While the project is technically maintained on GitHub, most community activity is initiated at the xTuple hosted community website where additional forums and technical documents are available.
PostBooks is written using English as the base language but has been or is being translated into several languages by the community at large including Spanish, French, German, Russian, Turkish, Chinese and Portuguese.
