To get your transaction history, log in to your account at BSCpro.com. From there, click your name or profile pic at the top right of the page. That will take you to the Profile page. Then, click the "Payments" tab and then the "Transaction History" button at the top right of the Payments tab.
After the transaction history loads up, you can then see each individual charge you have received. You can click the down arrow on the left to see the details of the transaction and you can click the download icon on the far right of the transaction if you would like to download a PDF copy of that particular transaction.
