Outbound Transfers (f.k.a. Payout) for credit card payments are made daily and contain payments processed two business days prior (this is how long it takes for your pending account balance to become available on this schedule). For example, payments received on a Tuesday are deposited by Thursday, and payments received on a Friday are deposited by Tuesday.

Outbound Transfers for ACH payments are deposited after the transaction has cleared (after 3-5 business days).

Stripe operates off of the UTC Time Zone:
All payments and Outbound Transfers are processed according to UTC time. As a result, the processed date may not be the same as your local time zone.
So the payments need to be made by midnight UTC (5/6pm ET - 2/3pm PT) to be rolled into the Outbound Transfer.
