@johnrushx It’s not about ads, it is early stage acquisition of your web traffic. Wondering about maintaining long term relationships with the successful ones, though, otherwise, looks smart enough.
@levelsio If you pay €100 for something using Stripe and after payment you generate an invoice, you can write off your expenses, that's true, but you can't get back the VAT amount, that's why reverse VAT exists. The VAT number has to be provided before payment.
