Do not like the new format?

Let me provide some information about the new invoice format, Austin.

May I know what specific format of the new invoice layout you don't like? In most cases, we redesign or reformat an existing layout to tailor features to the system's unique needs, and enhance financial organization, simplify bookkeeping, streamline invoicing and payment management, and ultimately save time and cost. 

With the new invoices, you can customize and adjust your forms right on the invoice that you are about to send. This means that there's no need for you to manage templates. Aside from that your customers can review and approve your estimate online from the email you send to them and get notifications as soon as they respond.

You may want to customize the look and info on your customer forms. See this resource for more details: Customize invoices, estimates, and sales receipts in QuickBooks Online.
