Your current account balance on your Stripe connected account is displayed on your dashboard in the shop backend.
It is also possible to evaluate the account balance and track your account movements in the account statements in the shop backend by offsetting all transactions since the last billing date. The account statements can be exported as an Excel file for this purpose.
From the time of the last billing date, the account balance is 0. If you have not received a payout, although orders have been received, your outgoing payments exceed the incoming payments since the last payout.
