How to set up a memorised transaction in Essentials for use as a blank template invoice. The blank would contain just the sales item and its price?

It's nice to see you here in the Community, communityoil,

I can provide information about setting up memorised transaction in QuickBooks Online.

The memorised transaction feature is only available in QuickBooks Desktop. In QuickBooks Online, what we have is the ability to set up recurring transactions for customers and vendors (such as checks, bills, invoices, sales receipts, estimates, etc). 

To create a recurring template, here's how: 

1. Click the Gear Icon at the top.
2. Under Lists, choose Recurring Transactions.
3. In the Recurring Transactions page, click the New button at the upper right hand. 
4. Choose the type of transaction to create, and click OK.
5. Enter a Template name. 
6. Choose a Type — Scheduled, unscheduled or reminder.
7. Enter the necessary information.
8. Click the Customize button at the bottom, then select Edit current.
9. Go to Content Tab and click the 2nd pencil icon which have the item details, then just put a check mark for Rate and Product/Service.
10. Click Done, then click Save template button.
