Looking for a Payment Platform Like Stripe (But Not Stripe) for a Global SaaS - I will not promote”

Hi everyone, We’re founders from Argentina and Uruguay, and we’re looking for a payment platform that works globally—something like Stripe, but unfortunately, Stripe doesn’t support our countries. We do plan to set up an LLC in the future, but first, we want to validate our market fit. Since we’re a bootstrapped startup, profitability from day one is a priority, so we need a payment solution that works for now without requiring a US entity. Has anyone used PayPal for a SaaS business? Would love to hear your experiences or any recommendations for alternative payment platforms that work well internationally. Thanks for your help!
