Hello there, @RBrown45.

Glad to have you here in the Community today. I'm here to ensure that you'll be able to upload your logo and save it on your forms in QuickBooks Online.

When uploading a logo in QuickBooks Online, you'll need to make sure that you meet the system requirements for it to be successful.

These are the following:

• The logo is a .gif, .bmp, .png, .jpg, .jpe, or .jpeg file
• File size is smaller than 10 MB
• Have a bit depth (or color depth) of 24-bits or less
• Uses the standard RGB color space (RGB)
• The shape of the logo is square. Rectangles don't work.

Once verified, you can proceed with adding the logo on your QuickBooks. To guide all throughout the process, please check out this article: How to add, customize, and troubleshoot logo on sales forms.

However, if the issue persists I recommend switching to another browser. This is to verify if the issue is browser related. If it works fine, you can go back to your previous browser and clear the cache. Sometimes the cache becomes bogged down with older data, which can affect views and performance in QBO. This article will walk you through the steps: How do I clear my browser cache and temporary Internet files? 

Please let me know how it goes, @RBrown45. I'll be around to provide additional assistance. Have a great day!
