I've got all the steps to help you scan and upload receipts in QuickBooks Online (QBO), cllw-consulting.
QuickBooks offers a Receipt Snap feature that allows you to scan and upload receipts. Then extracts info from it and creates a transaction for you to review. You can use the QBO mobile app to capture and upload receipts from your mobile device or upload them directly through the web interface.
If you haven't already, install the QuickBooks Online app for iOS or Android. Then, follow these steps to capture and upload the receipt:
Open the QuickBooks Online mobile app.
Go to the Menu ≡ icon.
Select Receipt snap.
Hit the Receipt camera and snap a photo of your receipt.
Click Use this photo, then Done.
