At this time, QuickBooks Online is planning to release the Receipt Capture feature. We'll be updating our QBO UK product updates page for details on when this becomes available.
For now, you can make use of theAttachmentfeature to upload receipt transactions. Then, manually enter the information before you attach the photo/PDF.
Let's start with enabling the Attachment feature by following the steps below:
Go toExpenseson the left panel, then chooseSuppliers.
Select the supplier you’re working on.
Click on theGearicon in the lower right-hand corner, and mark the box for Attachments.
Now, you can add the receipts attachment. If you have created an expense, open it and proceed to theAttachmentssection to upload the photo.
All you need to learn about managing attachments and acceptable file types can be found in this article: Attachments in QuickBooks Online.
