It's great to have you here in the QuickBooks Community, @bifrostfarm. I have the information to successfully record your Venmo transactions in QBO.
When recording the transfer, if you ever want to track your income and who has already paid, we can use your client's name to record. However, if you don't need to record and keep track of who has paid, we can use Venmo directly to record the transferred payment.
Additionally, I recommend contacting your accountant for further guidance on recording these transferred payments from your Venmo account.
For more information, you can visit this article on adding your bank transactions: Add and match Bank Feed transactions in QuickBooks Desktop.
To create custom fields, you can check this article: Create and use custom fields in QuickBooks Desktop.
