It's possible to delay the payment of commissions in one of two ways:
Delay the approval of the commission - This way, it isn't forwarded to your Payments page.
Use the "Up to" filter - You can use this feature to leave out commissions that are not yet eligible for payout.
This is useful in cases where you'd like delay the payment of commissions that are not past a refund period, or if you'd only like to pay the commissions up of a certain date (the end of the month, for example).
