Hi there, Melinav53.

Thanks for reaching out to us.

Currently, we're unable to delete the company logo once it’s uploaded to QuickBooks Online. For now, you'll want to consider uploading a blank white picture or replacing the company logo itself. I'll show you how:

1. Click the Gear icon, go to Account and Settings.
2. From the Company tab, select the Company name section.
3. Click the company logo, then select the Plus icon.
4. Upload a new logo or blank white picture.
5. When you're done, click Save.

Another workaround is to hide the logo on your sales forms. Here's how:
 

1. Click the Gear icon, go to Custom Form Styles.
2. Select the appropriate template, then click Edit from the Action column.
3. Under the Design tab, choose Make logo edits.
4. Click Hide logo.
5. Select Done to save the changes.

At times, we roll out updates based on our customers' requests. Rest assured, we're taking note of your ideas and suggestions to improve your QuickBooks experience.

Additionally, here's an article that you can read to help personalize your invoices, estimates, and sales receipts in QuickBooks Online: Customize sales forms.

If you have any other questions, just let me know and I’ll be happy to help.
