Thanks for checking in with us, Learning112.
You can enter the Ref No. or Payment No. in the Description column. To learn more about customizing your sales forms, you can check out this article: Customize invoices, estimates, and sales receipts in QuickBooks Online (QBO).
You can also add them as a custom field in the Header section of the template. Just click the Header part of the sample form and click the + Custom field link under the Display section. Then, enter the Ref No. and Payment No. in each field.
For more details about this one, please refer to this article: How to add custom fields to invoices.
In the meantime, let's perform some troubleshooting steps if this issue persist. To start off, try logging into your QBO account using a different or a private browser. There are times that the browser is full of frequently accessed page resources, thus causing some errors and/or unusual responses.
To use a private browser, here's how:
If it works, return to your default browser and perform clear cache to remove temporary internet files on your computer. Before doing so, make sure to take note of your saved passwords and URLs.
That's it! Give this a try and let me know how it goes by leaving a comment below. Please know that I'm only a post away if you have any follow-up questions. Wishing you and your business continued success..
