Thanks for joining us here today, @perminus.

I have some information about changing an item's account. First, you'll want to make sure you're logging in as the account Admin. This way, you're able to see the Also update this account in historical transactions checkbox. Otherwise, the previous transaction's account will not be changed.

After that, go to the Product and Services page to change the account. Refer to @DivinaMercy_N's post for details.

Additionally, try signing in to your QuickBooks Online (QBO) account using a private or incognito window. This mode doesn't use the existing cache data and helps us confirm browser-related issues. Here's how:

• For Google Chrome browser: Ctrl + Shift + N
• For Mozilla Firefox browser: Ctrl + Shift + P
• For Safari browser: Command + Option + P

That's all there is to it. In case you need help with other customer-related tasks, browse this link: Sales and customers.

Let me know how you get on after trying the steps, as I want to ensure this is resolved for you. Feel free to reply to this post and I'll get back to you as quickly as possible. Have a nice day ahead.
