KYC Automation for Cross-Border Payments in Emerging Markets

We're expanding into a few emerging markets, particularly for $USD-denominated cross-border payments. The challenge isn't just local compliance requirements, which vary wildly, but integrating a scalable KYC solution that can handle diverse document types and verification methods without becoming a bottleneck. Has anyone had success implementing an automated KYC provider that truly handles the nuances of multiple, less digitized jurisdictions efficiently? I'm less concerned with the 'big names' and more with actual operational performance and false positive rates.
