Generally, you should receive your money within 1-2 business days. ACH transfers can be initiated the same business day or next business day, depending on the time the advance was requested.
If it is your first time taking an advance, a bank verification will be needed. This is an additional step outlined here: How do I verify my bank account? The initial microdeposits to verify your account typically arrive 1-2 business days after your request. Once you receive those, you can verify the account, at which point the advance will be paid out. So, if you are a first time customer, you will receive your advance 1-2 business days after you complete the verification of your bank account.
