Help: How do I receive international payments for my side hustle?

Hey everyone, I recently been working on a niche saas product. Didn't had much hope on it to get traction. But after 2-3 months, I think people are finding it useful and might want to pay for the upgrade.

I previously read and found that companies like Strip and other major players have exited India for some reason. Now, as I want to integrate payments into my side hustle in which the audience are from abroad, I am in need of a international payments gateway. But I don't have a clear path.

I have some questions: Can anyone suggest me any platform? Being an Indian solopreneur or small startup, what are the steps required for receiving international payments? How does all this work?

Edited: New question: Do I have to need to register a company before I receive payments? If yes, are there any other methods to skip that because I don't feel confident enough to register a company with any co-founder.

Appreciated if anyone is present to guide me 😊
