Hi wn-u-s-c-ca,
Thanks for reaching out. Entering receipts on your QuickBooks Self-Employed is a good way to keep records of your transactions without having to store a shoebox full of paper. I know how important it is to be able to add all the information (front and back) from your receipts. I'll be happy to assist you with this.
QuickBooks Self-Employed supports PDF and image attachments. You can have your receipt as a two-page PDF document and easily attach it to your transaction. The limitation on file sizes is 15 MB.
To assist you with entering your receipt, here's a useful article: Enter receipts on your QuickBooks Self-Employed mobile app
