KYB for Small Businesses and Choosing a PSP

Looking into new PSPs for a small SME business. Don't have very high transaction volume, but need stability and reliability. Dealing with KYB from each provider has been a headache. Lots of documents, complicated, sometimes unclear what they really need. The process is slow, sometimes leading to missed opportunities. Customers can't pay.

Want to ask friends in the group if there are any PSPs with a reasonable KYB process for small businesses? Don't need anything special, just fast, functional, and on-time payouts. Don't want to keep asking when the money will arrive.
