How do i generate a quotation on quickbooks plus?

Hello, cwsimusokwe-gmai. 

Yes, estimate is the other term for quotation. To generate or create a Quotation is super easy. I'll show you how to do it: 

1. Click + New.
2. Select Estimate.
3. Choose a customer from the Customer dropdown.
4. If the work has already started, press a status from the Pending ▼ dropdown. This is optional.
5. Set the Estimate date and the Expiration date.
6. Enter the products and services you plan to sell.
7. Enter any other info you need.
8. When you're ready, tap Save and close. 

For more details about it, please see this article: Create and send estimates in QuickBooks Online 

On the other hand, If you wish to rename the Estimate to Quotation, we can go to Custom Form Styles. From there, we just have to modify it. Here's how: 

1. Click the Gear icon at the top.
2. Under Your Company, pick Custom Form Styles.
3. If you have a template for the estimates, click the Edit link below the Action column.
4. If you don't, click the New style button and select Estimates.
5. Go to the Content tab.
6. Select the header of the template.
7. In the Form section, change the Form name to Quotation.
8. Hit Done.
