Storefronts using Uscreen Payments Gateway or PayPal will display the amount on hold and the amount to be paid out in the Sales > Payouts Report. The payouts report is designed to provide an estimate for the expected payout so you know how much money to expect at the beginning of each month. It might change as refunds or disputes are in process, which is also the reason funds are held for 30 days.
On the first of each month, payout payments will be made for money collected in the previous month that have been held for 30 days. Example: All payments received in the month of May are paid out on July 1st. So payouts that haven't been held for 30 days are rolled into the 1st of the next month.
The Pending Transactions displays the amount received less than 30 days ago. Once the payment has been held for 30 days, then it will switch to Upcoming Payout which is how much you will receive in your next payout on the first of the month.
After the first of the month, you can review which payments have been paid out under invoices.
Navigate to the Sales > Invoices and you can see your invoices here along with some handy filters to segment invoices further.
