Debit Notes and Credit Notes in FBR Digital Invoicing

When an issued invoice needs correcting — a return, price change or adjustment — you use a debit or credit note referencing the original. Here is how these work in FBR Digital Invoicing.


Why you cannot just edit a filed invoice

Once an invoice is registered with FBR it is part of the record. Corrections are made through a separate note that references the original invoice, not by quietly changing what was already filed.

This keeps a clean, auditable trail of what changed and why.

Debit note vs credit note

A debit note increases the amount owed relative to the original invoice, while a credit note reduces it — for example after a sale return or a downward price correction.

Each must reference the original FBR invoice it adjusts.

The details FBR expects

Notes require the reference to the original invoice and a valid reason for the adjustment, and there are format rules for the reference number. Missing a reason or reference is a common cause of rejection.

The adjustment also cannot exceed what was on the original line it corrects.

How Digi Invoice handles adjustments

Digi Invoice lets you raise a note against an existing invoice, capturing the reference and reason FBR requires and validating the adjustment before it is posted.

That keeps corrections compliant instead of becoming a source of errors.
