What is the best ach payment processing for financial services? | Payment Gods Forum

Hey everyone, so I run a small financial advising firm, SecureWealth Partners, and honestly I'm getting hammered by credit card processing fees for larger transactions. We're talking like, fees eating into our margins big time on payments over $10k. I've heard about ACH but what is the best ACH payment processing for financial services specifically? I need something reliable and cost-effective as we just brought on a bunch of new high-net-worth clients.
