Hi jalee,

We will roll out updates for this through our QuickBooks blog. Here's the link for you reference, so you can keep up with all of what’s new and what’s coming soon in QuickBooks Online (QBO): https://quickbooks.intuit.com/blog/.

You'll want to follow the recommended steps provided by my peer, JonpriL, to add discounts on invoices.

Keep us posted if you have any follow-ups or other concerns. You can count on us.
