PostBooks: Free Open Source ERP and Accounting Software.

PostBooks is a full-featured, fully-integrated accounting, ERP, and CRM system, based on the award winning xTuple ERP Suite.

Built with the open source PostgreSQL database, and the open source Qt framework for C++, it provides the ultimate in power and flexibility for a range of businesses and industries. It includes the following modules:

• Accounting (general ledger, accounts receivable and payable, bank reconciliation, financial reporting)
  
• Sales (quotes, order entry, sales reporting, shipping)
  
• CRM (universal address book, incident management, opportunity management, to-do lists, project management)
  
• Purchasing (purchase orders, receiving, vendor reporting)
  
• Product Definition (items, infinite-level bills of material)
  
• Inventory (multiple locations, other advanced warehouse features)
  
• Light Manufacturing (work orders, strong support for make-to-order)
  
• OpenRPT open source report writer

Like all xTuple products, it runs equally well on Windows, Linux, and Mac - and is fully internationalized (multi-currency, support for multiple tax structures, and multilingual translation packs maintained by our global community).

PostBooks is licensed under the CPAL, the OSI-certified Common Public Attribution License.
