Currently:

• The original invoice retains the removed item with no visible indication of correction
• The correction is generated as a separate invoice with a new number -The only traceability exists in: >Action logs >Item-level history

However:

• These sources are not part of official billing documents
• They are not accessible to external stakeholders (e.g., auditors, accountants)
• Users must perform manual investigation to reconcile documents

Impact

• Reduced transparency in billing documents Increased effort in reconciliation and audit processes
• Confusion for clients reviewing invoices Risk of perceived inconsistencies in financial records.

Proposed Solution
Introduce visible linkage and correction indicators at the document level, such as:

Option A: Cross-reference between invoices

On the original invoice:

Add note: “Item corrected – see Invoice #XXXX”

On the correction invoice:

Add note: “Correction of Invoice #XXXX”

Option B: Correction indicator on line item

Show:

Original item marked as “Corrected” or “Reversed”
With reference to correction invoice

Option C: Linked document view

Add a “Related documents” section:

Original invoice ↔ Correction invoice
