Hi holycrosslaval-g,
Welcome to Community! QuickBooks Online is a dynamic program that provides the ability to import Customers, Suppliers, the Chart of Accounts, Products and Services, Invoices and Bills. At this time, there isn't a way to import sales receipts. I'd be happy to point you in the right direction, so you can accomplish your QuickBooks goals!
If you'd like to see this option available in feature updates, you can submit a suggestion to our Development team. In the interim, you can review the available apps that sync with QuickBooks Online, or follow the link directly from your QuickBooks account. Here's how:
1. Open Settings ⚙ in the top right
2. Under Tools, select Import Data
3. Scroll down to 'Need to bring in sales receipts, invoices, and expenses'?
4. Hit Try this app
Please feel free to reach back out if you have other questions. We'd love to help!
