Navigating Payout Reliability with Multiple PSPs for High-Volume FX

Hey everyone, fairly new to this side of the fintech game, transitioning from a more traditional prop firm background. We're looking at scaling up our retail FX offering significantly over the next 12-18 months, which means much higher daily transaction volumes and subsequently, much larger aggregate payout requirements.

My primary concern right now is payout reliability and efficiency, especially across different geographic regions. We've been using one major PSP for a while, and while their onboarding/KYB was a slog, they've been decent. However, relying on a single provider for what will soon be millions in daily payouts feels like putting all our eggs in one very large, but potentially fragile, basket. Diversifying seems prudent.

For those of you operating high-volume FX or similar retail trading platforms, how do you manage payout redundancy and reliability? Are you splitting volumes across multiple PSPs? If so, what criteria do you use to evaluate new partners beyond just fees and initial integration? I'm particularly interested in hearing about experiences with managing regulatory nuances and potential reconciliation headaches when using multiple payout channels. Any pitfalls or best practices for ensuring consistent liquidity and minimal delays for clients, especially when dealing with different banking cut-offs and holiday schedules globally? Just trying to get a handle on what might be coming down the pipe.
