I want to keep the format of the invoices but remove page numbers and I want add a watermark of my company name and also add 3 small images at the bottom

Hi there, @userreadytogohire.

Welcome aboard to the Community. I'm here to share some clarification about the invoice templates in QuickBooks.

If you're using the Airy new template, the option to remove the page numbers is unavailable. The only workaround is to change the template to a different one.

Here's how:

1. Click the Gear icon in the upper-right corner.
2. Select Custom form styles. 
3. Go to the Design tab.
4. Press Change up the template.
5. Change the template. 
6. Make the necessary changes.
7. Hit Done.

Also, the option to add a watermark and images at the bottom of the template isn't possible. For now, you can only add a single company logo, which you can add in the upper-left, right, or middle part of the form.

Though, it would be beneficial to have the feature in QuickBooks, too. Our engineers might be working to bring this feature over to this platform in the future. As we assess this, you can check our QuickBooks Blog for product updates.

For additional reference, you can use the following article to personalise sales forms in QuickBooks: Customise invoices, estimates and sales receipts in QuickBooks Online.
