Hi there. I just sent my first invoice but QB Self-employed didn't record it as revenue. Isn't that the best way to record income?

Glad to have you here in the Community, @MLapides.

The invoicing feature in QuickBooks Self-Employed (QBSE) won't affect the income account. You'll have to manually add a transaction from the Transactions page to record the revenue. Let me guide you through the steps.

1. In your QBSE account, click Transactions from the left menu.
2. Click Add transactions.
3. In the Category section, click Select a category and choose the income account.
4. Fill out the necessary information and click Save.

Here's an article you can read for more details: Manually add transactions in QuickBooks Self-Employed.
