Hi there, 

The new Receipts tab in QuickBooks Online allows you to manage and match your expenses with receipts in just a few clicks. Once you're done snapping your receipts and creating expenses, it's essential that you're able to review your digital copies so you can refer to them when necessary. I'll explain how you can go about seeing your previously scanned receipts. 

When a receipt is scanned/uploaded in the system, the corresponding transaction will be permanently linked with the receipt. In order to see the receipt you snapped, simply open the related transaction and scroll to the bottom of the screen until you see "Attachments". 

If you have any other questions, or need a hand finding your receipt, you can always reach out to our tech support team. 

Cheers.
