We are a thriving company in the food retail industry and are looking for a POS solution that can be partially (currently 3) expanded to include merchandise management or ERP.

• Expandable to merchandise management or ERP
• Inventory
• Invoicing (e.g., delivery notes, invoices)
• Purchasing
• Controlling, financial accounting
• Profitability report (with reporting) on, for example
• Profit and loss statement (P&L)
• Profitability, evaluations
• Personnel costs
• Cost accounting
• Interest
• Statistics
• Modular design would be advantageous
• DATEV interface
• Multi-client capable
• Windows compatible
• Network compatible

Warehouse management is not required.

In terms of software workstations, we currently plan to have 3 for merchandise management and 10 for cash register software for our three branches (each with 3 cash registers).
