The PurchasePaymentController (/purchases/payments) has been deprecated in favor of VendorPaymentController (/accounting/vendor-payments). 
    The VendorPaymentController provides enhanced features including:
    - Check printing capability
    - Multiple bill payment application
    - Journal entry integration
    - Payment status workflow (draft, printed, cleared, voided)
    - Bank account management
    
    Legacy routes at /purchases/payments remain active for backwards compatibility but should be migrated to /accounting/vendor-payments.
    Any new development should use VendorPaymentController.
