oh please do it! so many people NEED that platform. If you want more information, for example mercadopago (the financial arm of mercadolibre) which is the leading fintech in Argentina doesn't allow charing cards from the united states (or countries outside latam).
Which for SAAS is terrible
Oh I've been looking at MercadoPago too, didn't know they don't allow charging US cards (not an option then).
