Hello @1935 1451 4278 549,
You'll have to enter the discount as a whole number. Let me walk you through you how.
- Go to Gear, then Recurring Transactions.
- Edit the recurring invoice transaction.
- Scroll down towards the Discount percent section, then enter the "20".
- Click Save template.
Please see this article for more information about adding a discount to an invoice or sales receipt in QuickBooks Online. I'm also sharing with you our page about managing customers and income for additional reference.
That'll do it. Please leave a comment anytime if you have other questions or concerns. I'd be sure to reply as soon as possible. Thanks for visiting us today and have a wonderful day.
