How to correct a fiscalized invoice

Mistakes happen — wrong customer attached, wrong VAT applied, a line forgotten. Fixing a fiscalized invoice is a controlled process: cancel the original, issue a new corrected one. This article walks through the flow and the common cases.

The pattern

1. Open the original invoice. Verify it's truly fiscalized (IIC and NIVF present).
2. Cancel — actions menu → Cancel. The system sends a fiscal cancellation referencing the original. Status flips to CANCELLED.
3. Create a new invoice — same customer, corrected line items / VAT / amount.
4. Approve — submits to the tax authority as a fresh fiscal invoice. The audit trail now has the original (CANCELLED with old IIC) and the corrected (APPROVED with new IIC).
5. Reconcile payment — if the original was paid, decide refund vs new payment based on the difference (next section).

Common correction cases

Wrong customer (e.g., billed individual instead of company)

Cancel the original. Create a new invoice with the correct customer (the company), same line items, same total. If the original was paid, the payment record stays on the cancelled invoice — manually move it to the corrected invoice or refund and re-collect, depending on what the customer needs.

Wrong VAT rate

Cancel the original. Create a new invoice with the correct tax on the affected lines. The new total may differ from the old — refund the difference (or collect more) as the math requires.

Missing line item

Cancel the original. Create a new invoice with all the original lines plus the missing one. The corrected invoice's total is higher; collect the additional amount as a new payment on the corrected invoice. Don't issue a separate "supplement" invoice for just the missing line — fiscal authorities prefer one consolidated corrected invoice over a fragmented trail.

Wrong currency

Cancel and reissue in the correct currency. The fiscal record on the corrective uses the new currency from the start; the canceled original keeps its erroneous currency for the audit trail.

Avoiding corrections in the first place

• Verify customer, currency, line items, and VAT before clicking Approve. Once it's gone to the tax authority, the cleanup is more work.
• For complex invoices (groups, multi-currency, multi-tax), have a second person review before approving. Fiscal corrections are noisy on your reports and on the tax authority side; preventing them is cheaper than fixing them.
• Use DRAFT status as long as you can — drafts are freely editable. Only approve when you're sure.
