You can adjust the balance of an eligible Demo Account from its account card in the Client Portal.
Adjust a Demo Account balance
Sign in to the Client Portal.
From the left navigation menu, select Accounts.
Select Demo accounts.
Find the relevant Demo Account and select Deposit on its account card.
In the Balance adjustment field, enter the amount to add or subtract, not the desired total balance. Enter a positive amount to increase the virtual balance or a negative amount to decrease it. Check that the selected account is your intended Demo Account and that the currency and adjustment amount are correct, then select Confirm.
Return to the Demo Account card and check the balance shown.
Use the currency assigned to the Demo Account. Available values and controls can depend on the account configuration. If Deposit is unavailable or the balance does not update, open Service Hub and select Create Ticket.
