I'll ensure you can upload receipts in QuickBooks Online (QBO).
In QBO, you can upload receipts through your computer, mobile device, or your email account. Before you proceed with uploading receipts, please take note of the following:
We don’t recommend uploading receipts with sensitive or personal info, like credit card numbers and government identifiers.
QuickBooks supports PDF, JPEG, JPG, GIF, and PNG images. If you have a newer iPhone or iPad, your images might be in the HEIC format. You can convert HEIC images to a compatible format.
Once ready to proceed, refer to the steps below in adding receipts from your computer or Google Drive:
Sign in to QuickBooks Online.
Go to Transactions, then Receipts.
Select Upload from the computer or Upload from Google Drive.
Each image or file should only contain a single receipt.
However, if you have the QBO mobile app, you can also snap a photo of your receipt on your mobile device. See this link for guidance: Upload your receipts to QuickBooks Online.
