Why does it do this? When I upload my logo, it is a PNG, its shows with a black background.

Let's perform some troubleshooting steps to rectify the issue with your logo, Josh.

First, please create another copy of your logo and upload the updated version to ensure that the file isn't corrupted.

If the issue persists, I recommend clearing your browser's cache to eliminate outdated files. You can also consider using a supported browser to optimize your QuickBooks experience.

Once done, you can upload your logo again in QuickBooks.

You can always get back to us if you have additional concerns about QuickBooks.
