Credit notes and refunds

When an already-issued invoice is wrong or you need to return an amount to the customer, you don't delete it: you issue a credit note (rectificativa). In Aikount, credit notes are netted out of invoiced revenue, so both the KPIs and Modelo 303 keep reconciling with reality.

When to use a credit note#

• Void an issued invoice in full or in part.
• Correct a mistake in amount, base or VAT on a final invoice.
• Refund a customer for a sale that doesn't go through.

An issued invoice is already recorded in the books and numbered, so it isn't edited or deleted: it's corrected with a new document that references it.

How Aikount nets it out#

A credit note represents negative revenue. Aikount applies it to your sales figures so that:

• The period's invoiced revenue reflects sales minus credit notes.
• Output VAT is reduced in the same proportion, so the 303 captures the net amount.
• The Dashboard KPIs (Sales, Result, Margin) show the net, not an inflated gross.

Netting instead of deleting keeps the full trail: the original invoice and its credit note are both recorded, and the totals still reconcile. Deleting an issued invoice would break the numbering and throw the VAT out of balance.

Effect on the models#

Being negative revenue with negative VAT, the credit note flows into the models prepared from your accounting:

• Modelo 303: the credit note's base and amount reduce the quarter's output VAT.
• If the original sale was intra-EU, the adjustment is also reflected on Modelo 349.

Payments and refunds#

If you had already collected the original invoice and you refund the money, that outflow shows up as a bank movement to reconcile against the credit note. The reconciliation flow is the same as for any document: see How reconciliation works.

As always, Aikount prepares the figures; filing the models with the AEAT is up to you and your accountant.
