Iirc, with our current partner bank Evolve + technology provider Synapse, ACHs and wires have “Synapse” as the sender name on a certain field, instead of your business name.
This is (as far as I understand) wrong. Fortunately
it usually doesn’t break anything, but Circle is more strict about this saying the business name.
We have a new partner bank we just launched where we have full control of the ACH stack, where we’ve resolved this. Also trying to fix the issue with the existing partner.
Caveat that I didn’t check this answer with anyone, since it’s early.
We use to be with Synapse and Evolve too - have thankfully moved on ;) We went through the same pain with Synapse that it's their name and not the customer's name on the wire. I thought at Mercury's scale you could get them to change this by now.
Why can’t a Mercury wire or ach successfully clear to Circle?
As a Mercury customer what I know is that not a single one I’ve tried has worked resulting in days locked funds.
