Reference Number Handling in POS

1. Normal Sale Invoices (linked to Advance/Proforma invoices)

• The POS allows the operator to enter a reference number when finalizing the invoice.
• The system automatically validates and tracks the reference number to ensure consistency with the linked advance/proforma invoice.

2. Refund and Copy Invoices

• The POS requires a reference number to be entered.
• This ensures accurate linkage to the original invoice and prevents submission errors.

Automation and Compliance

• All reference numbers are automatically validated by the POS against FRCS TaxCore.
• The system prevents incorrect submissions, minimizing user error, as it operates in real-time online mode with TaxCore.
