Hello, @jsteb16-gmail-co.
Let me share some information on how you can maximize the use of QuickBooks Self-Employed in tracking your transactions.
QuickBooks Self-Employed is designed to track your business-related transactions from self-employment. Currently, the ability to enter a purchase order is not available. What you can do is track your actual income and expense transaction in the system and we will account for all business-related transactions for your estimated tax calculation.
You can connect your bank account with QuickBooks. Once your transactions are downloaded, you can categorize it into the correct self-employed category. To know more about expense categories and how they are shown on Schedule C report you can click this article: QuickBooks Self-Employed Schedule C Categories breakdown.
On the other hand, the feature to enter a purchase order is available in other QuickBooks products. You may want to check this article about different QuickBooks products and versions: See which version of QuickBooks is right for you.
Keep me posted if you have other questions about managing your transactions in QuickBooks. I'm always here to help.
