Buy now pay later - Double taxation

Hi,

We have multiple stores that issue simplified invoices to customers. For example, if a customer is charged 5,000 SAR, with 750 SAR as VAT, they might pay using a Tamara card (a buy-now-pay-later service).

At the end of the month, we invoice Tamara for the amounts owed to us. However, we are required to provide them with an invoice that again shows the VAT amount of 750 SAR.

Do we really need to generate a tax invoice in this case?
