I appreciate your timely updates, Tack. You can modify the logo on customer invoices through an online web browser. Let me add details to this.

Since the QuickBooks Online app has limited options for modifying invoice templates, it's best to add changes to your sales forms through the website.

You may want to open your QuickBooks account via the web browser available on your mobile device. This way, you can utilize the feature and include logos on your invoices.

Once you're logged in, you can refer to the steps outlined by my colleague ShyMae above, which details the process for modifying your forms.

Once everything looks good, you can enter customer-paid invoices into your account to ensure the accuracy of your sales entries.

Utilizing these comprehensive steps will help you manage customizations on your sales forms, Tack. Don't hesitate to reach out to us if you require further support. We'll ensure you receive the assistance you need.
