Error message if i want to attach a pdf file to an invoice for security reasons, we do not allow you to upload this type of file I have uploaded a hundered times before?

Hello Nimaloka_2003.

Let me share some details about the error when attaching a PDF file to an invoice.

Some of the QBO users are also having issues with uploading PDF files to invoices and sales receipts. Our engineers are currently working on finding the cause, so they can implement a fix.

As a workaround, try removing the extra space between the file and the extension. The file name should look like this "filename.pdf". Then add the attachment once more.

Here's how:

1. Find and open the desired invoice.
2. From the bottom left, select Attachments.
3. Browse and select the document you want to attach.
4. Select Open, then Save and close.

While the investigation is ongoing, I'd suggest contacting our phone support team so we can add you to the list of affected users. This way, we can notify you via email about the status of the issue.

Thank you for your patience while we're working to resolve this. Please feel free to let me know if you have other questions about QuickBooks Online. Have a good one.

Disappointing to see this is a known issue from December 2018 and still occurring. 

Thank you for reaching in the Community, @Sherrinotafan.

I understand how you feel when something isn't working in QuickBooks Online. I am here to let you know that this error has been resolved by our engineers. If you're still getting the same behavior, let's clear the app's data to refresh the connection.

To start, let’s log in to a private window and access your account there. This way, you'll know if it's your browser that’s causing the error.

Here are the keyboard shortcuts:

• Google Chrome: press Ctrl + Shift + N.
• Mozilla Firefox: press Ctrl + Shift + P.
• Internet Explorer: press Ctrl + Shift + P.
• Safari: press Command + Shift + N.

If you can successfully isolate the problem, proceed to clear the cache. Clearing cache and cookies will also help improve your experience in navigating your account. The following link will walk you through the steps: Delete or Disable Cache and Temporary Internet Files in Your Web Browser.

Once it work's fine as suggested, let's proceed to the workaround provided by my colleague above then try to add the attachment again.

Please let me know how it goes or if you need further assistance. I'll be around to help. Take care!

This isn't a browser issue. I too am having the same issue when trying upload receipts.

I am trying to upload some receipts saved as pdf files in the attachments and I am getting an error. I tried with images as well and still the same error. Please help

QBO throws this error when an ampersand character (&) is used in the filename.

This is still an issue 10/2022.

I have tried all the solutions mentioned and nothing works. There are no special characters in the file name. 

What's Frustrating is that I was uploading the exact same types of documents just a month ago with no issues, and now for some reason any receipt I try to attach to an expense gives me this error message. 

It would be extremely helpful if QBO could at least include an "information" icon explaining what type of document is flagged for security reasons.

Very frustrating.
