Credit card fees, what is everyone using as their processor?

I paid 15k in credit card fees last year. Yes, I’m aware it’s just part of my overhead, but does anyone have a better processing company they use that doesn’t take 3%. I use honeybook because it just streamlines my backend.

To be clear, I am aware I can -

A. Pass the cost on to the client either by wrapping it in to my pricing, or charging them 3% if they would rather pay with card over bank transfer/check.

B. Use a third party app like Venmo/cash app/zelle.

I want to keep taking card as I know clients appreciate it for the points/convenience/etc.
