Hello again, @David Press.
QuickBooks Self-Employed (QBSE) features simple invoicing, which helps create professional-style invoices for use in billing your clients.
As mentioned by GeorgiaC, able to import invoices in QBSE is not an option. For the meantime, you'll need to enter each invoice manually. We're always looking for ways to improve QBSE, so we appreciate you sharing your ideas. Rest assured, I'll share your comments with our Product Development Team so they may consider this for future upgrades.
To know more on how Invoice feature works in QuickBooks Self-Employed, you can check this article: Create an invoice in QuickBooks Self-Employed.
If you're unsure about committing to a new version of QuickBooks, you can test out the products for 30 days. Just go to this link https://quickbooks.intuit.com/uk/pricing/ and select Free one month trial.
If there's anything else I can help you with in managing your QuickBooks account, please let me know by commenting below. I'm more than happy to further assist you.
