Shift Pay is "Available Now" or "On the Way"
Edited
If you have a payment in your payout dashboard as "Available Now":
The business has paid you for the Gig. You can Instant Pay this money if you have a debit card as your payout method. Only funds that are listed as "Available Now" can be Instantly Paid.
If you have a payment in your Payout Dashboard, "On the Way":
Stripe has automatically transferred the funds to your account, which they do every business evening between 9 pm and midnight if there are funds in your Stripe account to send.
Once funds are "On the Way," they cannot be Instant Paid.
