Where are the payments for export in the balance of payment? I know that when we sell some goods abroad, we credit Goods&amp;Services part within Trade balance, which is a part of Current Account.

What part of the Financial Account is debited with the sum received for the exported goods?
The physical part of trade in goods and services is recorded in the Current Account and the payment (with financial assets) part of the transaction is recorded in the Financial Account. The Balance of Payments should be 0 after you sum up the Current Account balance, the Capital Account and the Financial Account balances. The trade in goods and services is recorded in Current Accounts. For instance, exports are credited and imports are debited.
