PSP Integration and KYC/AML Bottlenecks for Multi-Jurisdiction Operations

We've been navigating the complexities of integrating new payment service providers (PSPs) for client onboarding across multiple jurisdictions, particularly in LatAm and parts of SEA. The promise from many sales teams is always seamless integration and rapid KYC/AML. The reality, as most of us know, is often a drawn-out process, especially when dealing with nuanced local regulations and varied documentation standards. We've seen significant delays in client activation purely due to the PSP's internal compliance queues or unexpected document rejections that feel arbitrary.

My question to the room is, what are your practical experiences in mitigating these onboarding bottlenecks? Are there specific PSP characteristics, beyond just the quoted transaction fees, that you prioritize to ensure a smoother, faster client journey? We're finding that even with API-driven solutions, the human element of KYC/AML review at the PSP level remains a significant chokepoint, directly impacting our ability to scale efficiently. Any insights on how you've streamlined this, or specific questions you now ask prospective PSPs during due diligence to uncover these potential friction points upfront, would be greatly appreciated. It feels like a constant battle between speed-to-market and regulatory thoroughness, with the PSP often dictating the pace.
