Hi there, @usersrstephentn.

I'll share some learning about estimates in QuickBooks Online (QBO). 

Yes, both questions. You can create an Estimate template with the line items filled in using the Recurring transaction. That way, they will update products or services in QBO when you fill in the quantity and price numbers. 

Let me guide you how: 

1. Go to the Plus icon, then chose Estimates. 
2. Complete all the necessary data in the field. 
3. Hit the Make Recurring button on the bottom part.
4. In the Type drop-down arrow, choose Unschedule. So, you're able to copy and edit the customer's name anytime you need it. 
5. Tap Save Template.

I've added some articles about importing templates, memorizing reports, and other topics.

Please let me know if you have any more questions or concerns. I'm only a Reply away. Have a good rest of your day!
