Proposed Module Structure:
  1. Customer Module
- Customer list
- Customer details (contact info, address, etc.)
- Customer-specific pricing and discounts
- Sales history and order tracking
  1. Vendor/Supplier Module
- Vendor/Supplier list
- Vendor/Supplier details (contact info, address, etc.)
- Vendor/Supplier-specific pricing and terms
- Purchase history and order tracking
  1. Invoicing/Billing Module
- Integrated with Customer Module for sales invoices
- Integrated with Vendor/Supplier Module for purchase bills
- Automatic population of customer/vendor information
- Array passing for customer/vendor selection
Benefits:
  1. Improved organization and data management
  2. Enhanced customer and vendor relationship management
  3. Streamlined invoicing and billing processes
  4. Reduced errors and increased accuracy
  5. Better reporting and analytics capabilities
Technical Requirements:
  1. Database design to accommodate separate customer and vendor tables
  2. API integration between modules for data exchange
  3. Array passing mechanism for customer/vendor selection
  4. User interface updates for seamless navigation between modules
  5. Data validation and security measures to ensure data integrity
Invoicing/Billing Module Workflow:
  1. User selects "Create Invoice" or "Create Bill"
  2. System automatically loads customer or vendor array based on selection
  3. User selects customer or vendor from array
  4. System populates customer or vendor information
  5. User completes invoice or bill details
  6. System generates invoice or bill document
Array Passing Example:
// Invoicing Module
customerArray = CustomerModule.getCustomers();
// Pass customerArray to invoicing form
// Billing Module
vendorArray = VendorModule.getVendors();
// Pass vendorArray to billing form
Implementation Roadmap:
  1. Database design and API integration
  2. Customer and Vendor Module development
  3. Invoicing/Billing Module updates
  4. Testing and quality assurance
  5. Deployment and training
By incorporating separate Customer and Vendor/Supplier Modules, Wafeq will provide users with a more comprehensive and efficient business management solution.
