Welcome to the Community, @bskerrett.
In QuickBooks Self-Employed (QBSE), invoice transactions aren't connected to the Transactions tab. You'll have to manually add a transaction for the paid invoice to record it as an income. Let me walk you through the steps.
- Click Transactions from the left menu.
- Select the Add transaction button.
- Enter the invoice information and the amount.
- Choose the income category from the Category section.
- Click Save.
Here's an article you can read for more details: Manually add transactions in QuickBooks Self-Employed.
However, if the payment is coming from your bank and it's connected to your QBSE account, you don't have to enter a transaction for the revenue. The income transaction will flow to your QBSE account once downloaded.
