Yes, that’s the point. Is not 15 days, is the 15 day of the following month, but my understanding is that is after payment. In fact the wrong invoices sent were sent *before* IETF itself started, which make sense, because you already paid even if the “service” has not yet been provided.

I am not a lawyer and not a tax accountant but I was curious where you got the 15 days “after payment” from. According to German UStG 14 / 2 / 2 I would think generally it’s “within 6 months” after execution of the service. Given you are in .ES (and that’s why this matters mostly) UStG 14a / 3 probably applies which says “has to write an invoice until the 15th day of the month following …” Is that where it’s coming from? But given Alexa has already followed up that they are on it, I am sure it’ll all solve itself quickly. Maybe they can add a reference to the VAT FAQ ;-) /bz
