How do I add a purchase order box to my invoice?

Hi there.

You can add a purchase order field to your invoice transaction by enabling custom fields in QuickBooks Online, and I'm here to show you how. 

First, let's ensure that you have turned on the purchase order feature. Then, we can proceed to set up your custom fields.

Here's how:

1. Go to the Gear icon and select Custom fields.
2. Click the Add Custom field button.
3. Enter a name in the Name field, such as Purchase Order.
4. Toggle the All Sales forms or Purchase Order checkbox. Or, select both.
5. To show the custom field on printed and delivered forms, turn on Print on the form. Otherwise, it’ll only appear in QuickBooks Online.
6. Select Save.

After setting up your custom fields, you can now see the Purchase Order box field when you create or open an invoice.

You can also consider adding purchase orders to expenses, bills, or checks in QuickBooks Online.
