My purchase orders aren't attaching when I save and send them to vendors.

I hear your concerns about the purchase orders not attaching in QuickBooks Online, info2050. It can be challenging when the same problem persists, but we can work together to resolve this issue.

One possible explanation for the attachment issue is an underlying browser issue caused by saving outdated and corrupted cache files. These files can occasionally cause issues like navigation and attaching documents to transactions in QuickBooks Online.

Let's go through some troubleshooting steps to identify and resolve any browser-related issues. We'll begin by accessing your QuickBooks Online account from a private/incognito window. Depending on your browser, use the following keyboard shortcut to open one:

• Google Chrome and Microsoft Edge: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P

If you can attach the purchase order after saving and sending it to the vendor, return to the main browsing window and clear the browser's cache. This will remove any outdated or corrupted internet files that could be causing the problem.

Alternatively, you can look and use other supported browsers for the best experience while working in QuickBooks Online. 

If you have any additional questions or concerns about the vendor, please leave a comment below. I'll review your response in this thread.
