In the opinion, the SAT indicates that advance payments for services for events, presentations, conferences, and other types of meetings cannot be considered as payments for a service provided for remuneration, since the service will be provided on a future date. Therefore, according to the opinion, no invoice should be issued at the time of the advance payment because the requirements established in the VAT law are not met; instead, a receipt for advance should be issued. When the service is provided, the corresponding invoice should be issued and any remaining balance due for the service should be settled.
