Payments and Safe-to-Spend
If you'd like to save up for a payment over time, you can choose to create a Goal for the payment. Right now, this option is only available on the web.
If you choose to create a Goal for the payment, it'll save over time and it'll be scheduled to complete just before the payment is sent. Funds will slowly move from your Safe-to-Spend to the Goal, and once the payment is sent, the Goal will be automatically archived.
Please note: payments will be sent normally even if the Goal is not complete, as long as your total available balance is enough to cover the payment.
