Hello, I want to create Purchase order direct from invoice, how can I do that with one click ?

Hi sales-cafeapplia,

It is not possible to create a purchase order from an invoice. However, you can create a purchase order manually in QuickBooks Online by following these steps. 

1. Select + New.
2. Select Purchase order.
3. From the Supplier ▼ dropdown, select the supplier.
4. Enter the Purchase Order date.
5. Enter details needed.
6. Select Save.

Also, you can check on this article for your reference: Copy a quote to a purchase order.

Let us know if you need further assistance. Have a nice day!

You can create a quote on another app and integrate it with your QBO. Once your client approved it, you can convert the data to purchase order with a single click.
