Glad to have you here in the Community, lasaindustries@y.
Usually, this error occurs when there's too much cache in the browser. To fix this, let's perform some troubleshooting steps. Let's start by accessing the QuickBooks account using a private browser. The following are the shortcut keys you can use:
- Google Chrome: press Ctrl + Shift + N
- Mozilla Firefox and Microsoft Edge: press Ctrl + Shift + P
- Safari: press Command + Shift + N
If this works, you can clear the cache and cookies of your browser. If not, you can use another supported browser. Possible that your current browser may have a temporary issue with QuickBooks.
I've also added this link about adding HSN to your invoices: How to add HSN and SAC codes to your products and services.
Please know that you can always get back to us if you have other questions. I'm more than happy to help. Take care.
