It can be challenging when you can't inactivate an expense, FPCNS. I'm here to share some details about this.

When you create your company in QuickBooks Online, specific default accounts are created for you depending on the business entity you selected. On the Chart of Accounts page, it’s important to understand that some of them can't be deactivated.

I've listed the following accounts that you're unable to inactivate:

• Undeposited Funds (also called Payments to Deposit When you record a payment to your company, the funds are added to this account until you deposit them into your bank account.
• Opening Balance Equity: This is the default account for adjustments.
• Retained Earnings: This account reports the net income of your company on the Balance Sheet report. 
• Inventory/Stock Asset and Cost of Goods Sold/Cost of Sales: If you try to edit or deactivate these accounts, any edits to your Products/Services will be recreated.
• Sales of Product Income: This is used to track sales for inventory items. 
• Reconcile/Reconciliation Discrepancies: This account is created if you reconcile an account and the transactions in QuickBooks Online don't match the transactions reported on your bank statement.
• Unapplied Cash Payment Income: This account is created if you record a cash payment from a customer without applying it to a sales form, such as an invoice.
• (Sales tax agency name) Payable: This account is created if you set up sales tax for a tax agency. 
• QuickBooks Checking: When you activate QuickBooks Checking, the QuickBooks Checking bank account is created. 
• Uncategorized Expense and Uncategorized Income: These accounts are created automatically and track money your business earned or spends that still needs to be categorized.
• Uncategorized Asset: This account records any asset that can’t be matched to an account.
• Owner's Equity (also called Owner Draws, Owner’s Investment, or Owner’s Pay & Personal Expense This account represents the cash or assets you’ve invested in the company.
• Services: This is the default income account in QuickBooks Online.

If the account is listed above, it is the reason why you encountered an error. Otherwise, I suggest accessing your account using a private window. This way, we can determine whether this is a browser cache-related issue. The browser utilizes cached data to load web pages quickly. However, excessive cache can lead to problems that impact the appearance and functionality of your account.

An incognito mode helps us verify the issue since this doesn't save any files. Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + N

If you inactivate it, clear the browser's cache. Doing so deletes all the data from your browser and optimizes its performance. Using other supported browsers also helps us verify if this is a browser-specific issue. 

Please let us know if you have additional questions about inactivating accounts or any QuickBooks-related concerns. I'm always here to lend a hand. Stay safe and well.
