Hi there,
That's a great question. QuickBooks Online is designed to be flexible with your needs, and branding is so important to any business. I can appreciate that the template options may not be exactly what you're looking for. While the template options don't vary between the plans, it's possible to upload your very own invoice or estimate template from a Word document.
To upload a custom invoice or estimate template, follow the steps listed in this article: Import custom form styles for invoices or estimates. This feature helps reflect your brand identity into your sales forms with less effort and time.
I hope this helps get all your questions answered. If you need help uploading your custom template, please don't hesitate to reach out to our tech support team for assistance.
Cheers!
