Ready-Made Sales & Warehouse PHP App

I'm in urgent need of a pre-existing, robust PHP application for sales and warehouse management. Time is of the essence, and I don't have the bandwidth to oversee the development of a new application.

Key Features:
- Comprehensive sales tracking
- Detailed reporting and analytics
- Efficient warehouse application management

Platform Compatibility: The application needs to be:
- Fully operational on Linux
- Compatible with PHP

User Access: The application must support:
- Multiple users

Ideal Skills and Experience:
- Proven experience in PHP application development
- Prior work with sales and warehouse applications
- Strong understanding of Linux compatibility
- Experience with multi-user system design

Please only bid if you have a ready-made application that fits these specifications. Thank you.
