Are there different versions of QB that may or may not allow Vendor Payment Discount Terms? Where I set up new terms there is not an option to insert the discount amount.

QuickBooks is an easy-to-navigate program that helps you to manage your accounting with ease. I'll provide ways on how you can apply Vendor Payment Discount Terms, whether you are using QuickBooks Desktop or QuickBooks Online.

If you're using QuickBooks Desktop, you can update your QuickBooks and find the Set Discount button. You can also create a Vendor credit and apply it as partial payment to the bill, then pay the remaining amount.

1. From the Vendors menu, select Enter Bill.
2. Choose the Credit radio button just above the Bill transaction name.
3. Select the vendor and enter the discounted item and the amount.
4. Click Save.

Pay the bill the usual way, then click on Set credits and select the credit you created.

If you're using QuickBooks Online, there's no Set Discount button when paying a bill, but you can create a vendor credit and apply it to the bill. Here's an article for your reference: Enter a credit from a vendor.

Since the Vendor Payment Discount Terms are not yet an actual feature, I recommend leaving feedback by heading to the Gear icon and selecting the Feedback option. These comments are viewed and considered by out developers as they create new feature and updates for QuickBooks.

I hope this helps! If you have any other questions, feel free to reach back out here.
