What does the ACH process look like? As far as I understand I can simply give a customer by banks ACH/routing info and have them pay directly.

If there's some value add here I'd jump on it. Offering ACH has been a significant credibility boost with my (enterprisey) customers.

Also, wow you guys have grown. I remember when your team page had two rows.

Is BACS in the pipeline?

(BACS is the UK equivalent of ACH as far as I can tell.)

No, it's not. ACH (which standard for 'automated clearing house') is just a bank transfer - and a slow one at that.

Direct Debits in the UK are distinct to bank transfers because they're guaranteed by the bank - you can dispute a direct debit and have your bank refund it, but this is considerably harder (if not impossible) to do with ACH.
