Convert Purchase Order or Bill to an Estimate

Thanks for checking out the Community, Chrispotter

Currently, this functionality is unavailable in QuickBooks Online. As a workaround, you can manually create the estimate. Then, add a note or memo to indicate that it's based on the bill or purchase order. I'll guide you how:

1. Select the + New button.
2. Select Estimate.
3. Select a customer from the Customer dropdown.
4. If the work has already started, select a status from the Pending drop-down menu. 
5. Set the estimate and expiration date.
6. Enter products and services you plan to sell.
7. Enter the memo and other necessary information.
8. When you're ready, click Save and close or Save and send.

Alternatively, you'll want to go to our QuickBooks App Market or head to the Apps menu in your QBO account to find a third-party app that best suits your business needs.

I'm also adding these articles to learn how to personalize and convert an estimate to an invoice: 

• Create and send estimates
• Customize invoices, estimates, and sales receipts
