Hi there, SP Enterprises.
Can you tell us what happens when you entered a 6-digit HSN code? I tried adding a new product with a 6-digit HSN code and I was able to save it. In the meantime, I'll share some steps to check if too much cache or a browser issue is preventing you from saving or entering the HSN code.
Start by using an incognito/private browsing session or a different browser. Here are some of keyboard shortcuts to quickly open an incognito session:
- Ctrl + Shift + N for Google Chrome
- Ctrl + Shift + P for Firefox
- Control + Option +P if you're using Safari
- Ctrl + Shift + P for Microsoft Edge
Once done, go back to your account and check if you can already enter the 6-digit code. If you're able to do that, follow the steps in this article to delete your browsing history: Clear Cache And Cookies To Fix Issues When Using QuickBooks Online.
Let me also share these articles with your for more reference about adding HSN codes in QBO:
