Navigating Payment Processors for Offshore Digital Banking

Trying to get a better handle on the current landscape for payment service providers (PSPs) when setting up an offshore digital banking presence. We're past the initial setup with the bank itself, but the friction point now is really streamlining the onboarding and KYB process for our clients through the PSP. It feels like some providers are still operating with processes that are surprisingly archaic for the digital age, leading to significant delays and client drop-off. For those of you who've successfully integrated robust PSPs with offshore accounts, what's your experience been regarding their technical integration capabilities and, more critically, their approach to efficient, yet compliant, KYB for a global client base? Are there specific types of PSPs better suited for this, or perhaps red flags to watch out for beyond just fees and payout reliability? Any insights on mitigating that initial onboarding drag would be genuinely helpful.
