Predictably fast ACH payments
ACH payments can feel like a black box. They can take several business days to complete and it’s unclear when funds will be available.
We offer same-day ACH, submit at every Fed window, and provide robust settlement tracking. This means that your payments can arrive in less than 24 hours—often even quicker.

Preview every inbound payment
Increase lets you preview incoming ACH transfers for one hour before allocating them. This gives you flexibility to reject unwanted debits or fund accounts just-in-time. For advanced use cases, create your own allow or disallow lists and write specialized rules or limits.
