Hello mjjconcreting-bi!
Entering income is the most exciting part of a business bookkeeping activity, and I'm happy to share how to do this in QBO.
You can record your income based on your actual transactions. For example, if you issued invoices, you can record them as invoices as well. If you provided sales receipts, you can create sales receipts as well. To do these, simply click the +New button on the left-hand side and choose Invoice or Sales Receipt.
We have a test account. You can use it to practice entering transactions before using your actual account. You can also check out our Help articles. You can click on the Manage customers and income section for more references for customer-related activities.
You can always go back to this thread if you still have questions about recording an income. The next available agent will continue to assist you. Stay safe and enjoy the rest of the weekend!
