Let me share a few details with your QuickBooks chart of accounts so you'll know the closest option on how to handle your issue, Matteo.

The chart of accounts provides an overview of your business and how the different financial parts are performing. When you create your company file, QuickBooks Online (QBO) automatically sets up standard accounts and gives you additional ones based on your business entity. Keeping them organized will help you especially when it's time to file your taxes.

Currently, inactivating accounts is the only option that you can do instead of deleting them. However, you can still add more accounts anytime if you need to track other types of transactions. To do so, follow the outlined steps below:

1. 1. Go to Settings ⚙ and select Chart of accounts.
   2. Select New. Depending on your account view, you’ll either see a panel labeled New account or New category. Select the option you see below for next steps.
