CREATING PURCHASE ORDER IN QB ESSENTIALS VERSION

Good evening, @Pridepro1. 

Welcome to the Community! I'd be more than happy to help you create purchase orders in your QuickBooks Online Essentials account. 

Have you turned on the purchase order feature? This feature allows you to create PO's and more. Here's how: 

1. Go to the Gear (Settings) icon in the top right-hand corner. 
2. Choose the Account and Settings option under the "Your Company" column. 
3. Tap the Expenses tab. 
4. Press the Pencil (Edit) icon in the Purchase orders section. 
5. Turn on the User purchase orders option. 
6. If you want, enter up to three custom fields and a default message for vendors. These are optional. 
7. Click Save and then Done when ready. 

For more details about PO's, review this guide: Create and send purchase orders in QBO. 

This should do the trick. If you need any more assistance, don't hesitate to ask. Have a great day!
