Vendor payment terms The vendor information payment terms is filled in as Net 30. How do we get the payment terms to appear on PO's that we issue to our vendors?

I'll take care of your query about adding payment terms in purchase orders, userjgarcia.

Currently, purchase order (PO) formats are automatically set, and there isn't an option to add payment terms. As a workaround, you can consider using the custom fields to manage them. This way, you have custom data for more flexibility in having detailed reports.

For QuickBooks Online (QBO) Simple Start, Essentials, or Plus, here's how:
 

1. Go to the Gear icon, then select Custom fields.
2. Click Add field. If this is your first time creating a custom field, select Add custom field.
3. Input a name in the Name field.
4. Select the Purchase Order checkbox.
5. To show the custom field on printed and delivered forms, turn on the Print on form. Otherwise, it’ll only appear in QBO.

If you are using QBO Advanced, check out this article: Create and edit custom fields in QuickBooks Online Advanced.

Moreover, you can refer to this article when adding your purchase orders to expenses, bills, or checks: Add purchase orders to expenses, bills, or checks in QuickBooks Online.

Please don't hesitate to comment below if you have other questions about managing your purchase orders in QBO. I'll be willing to lend a hand at any time. Stay safe.

Weird. QuickBooks Desktop has fully customizable PO Templates, like all of its sales forms, and it's super easy to add Terms to a Template:

I suspect you can add Terms to the PO Templates when using QuickBooks Desktop because it makes sense and customers want them.

Maybe Desktop is a better version of QuickBooks? Yea, I think so too.
