Onboarding Friction for SMBs into Crypto PSPs

We've been exploring a few different crypto payment service providers for our platform, particularly looking at how they handle onboarding for small to medium-sized businesses. The KYC/KYB process seems to vary wildly, and some of the documentation requirements feel a bit over the top for smaller entities just trying to accept crypto. I'm curious if others have experienced similar hurdles or found particular providers that streamline this without compromising compliance.

Specifically, what has your experience been with the time to approval, and how transparent were they about the reasons for delays or rejections? It feels like some of these processes aren't built for speed, which is critical for growing a fintech startup.
