Onboarding & KYB for scaling B2B fintechs – hidden costs and red flags

Hey everyone,

Been thinking a lot lately about the long-term impact of initial broker/PSP choices, particularly from an infrastructure and scaling perspective. We're a fintech providing a niche B2B payment solution, and while we've navigated the initial hurdles of finding partners who could handle our specific transaction types and volumes, I'm starting to see how much the onboarding and ongoing KYB processes can either accelerate or seriously bog down growth. It's not just about the upfront API integration; it's the operational overhead of constant documentation updates, re-verifications, and the sheer variance in how different providers interpret and implement AML/KYC regulations. We've had situations where a relatively minor change to our corporate structure led to weeks of suspended payouts from one provider, while another barely blinked. It makes me wonder about the true 'total cost of ownership' beyond just spreads or transaction fees.

My main question to those of you scaling similar ventures is: what are your red flags when evaluating potential partners specifically around their onboarding flexibility and ongoing compliance demands? Are there any specific contractual clauses or service level agreements you push for to mitigate these operational headaches down the line? We're trying to move towards a more proactive stance rather than reactive problem-solving, especially as we eye new markets where regulatory landscapes are even more complex. The friction from a cumbersome KYB process isn't just an annoyance; it directly impacts our ability to onboard clients swiftly and reliably, which is critical for our growth trajectory. Any shared experiences or best practices here would be invaluable.
