Submission Windows

ACH transactions are processed in batch submissions once per business day. Standard ACH settles in 1–2 business days; Same-Day ACH settles the same business day when submitted before the daily cutoff.

Settlement	Settlement Timing	How to Request
Standard ACH	1–2 business days	Default
Same-Day ACH	Same business day	Set `SameDay: true` on the request

ACH is not processed on US federal holidays or weekends. Transactions submitted after the daily cutoff are queued for the next business day.
