New merchandise management system wanted

We are looking for a new merchandise management system for our mechanical engineering company. The following functions are required:

• Sales
• Purchasing
• Warehouse management
• Order management
• Parts lists
• Optional serial number management
• Manufacturing/Production
• Planning
• Scanning via barcode
• Confirmation still manual, but should become automatic
• Project management
• Quality management (ISO 9001 certification coming soon)
• Time recording
• Payroll and accounting
• Financial accounting
• Intercompany

Interfaces to the CAD system AutoCAD and to MS Outlook are required. Furthermore, it must be possible to convert data into Datev format so that it can be sent to the tax consultant.

The system should be installed locally on a Windows server. Open source systems are also considered. A Turkish language component would be ideal due to a Turkish branch office, but is not mandatory. We want to make a decision by the end of 2014 and start implementation on 01.01.2015.
