Corrective invoices: fixing an invoice under VeriFactu
Under VeriFactu an issued invoice is not edited or deleted: it is fixed with a corrective invoice. In FacturAda you create it from the original, pick the AEAT reason and the software assigns the type (R1, R2 or R4), links it and sends it to the AEAT.

How it works
Once the AEAT accepts an invoice, FacturAda locks it. A correction is a new corrective invoice that inherits the original's data, gets its own hash in the VeriFactu chain and is sent like any other invoice.
Open the original
From the invoice detail choose «Rectify».
Pick the reason
Select the AEAT reason code; FacturAda assigns the corrective type.
Fix the data
Corrective invoices are issued by substitution with the correct amounts.
Record and send
It gets its own VeriFactu record and is sent to the AEAT.
Corrective types FacturAda issues
| Type | When | Reason codes |

| R2 | Unpaid output VAT with an insolvency order | 85 |
| R4 | Invoice data: number, series, date, issuer, recipient, addresses, operation detail, period, invoice class or legal wording | 01 to 10 and 13 to 15 |
Frequently asked questions
Can I edit an invoice already sent to the AEAT?
No. An accepted invoice is locked. A rejected one can be fixed and resent; an accepted one needs a corrective invoice.
Can I query corrective invoices via API?
Yes, with GET /rectified-invoices. The API does not allow editing or deleting invoices.
