I'm glad to hear that you are using QuickBooks to help you manage your business.
In QuickBooks Online (QBO), we can input orders by creating an estimate. Then, convert it into invoices. Estimates are non-posting transactions and will not include in the Profit & Loss report.
Currently, QBO doesn't have a final production list. However, we have a Product/Service List that you can review every day. I'd also suggest utilizing the inventory tracking feature in QBO: Add inventory products in QBO.
Here's how to create an estimate:
Go to the +New button.
Under Customer, choose Estimate.
Choose your customer from the drop-down arrow.
Select the Product/Service from the drop-down arrow.
