Can I add a 2nd chart of accounts to record entries through our second bank account to track a second type of work performed - all under the same entity

Hi there, 

Chart of Accounts is the complete list of all the company’s accounts and balances. In QuickBooks Online, it represents and organizes the company's assets, liabilities, income, and expenses. You can tell how much money your company has, how much money it owes, and how much money is coming in and out by simply looking at your Chart of Accounts. I'll help shed some light on recording entries for a second bank account. 

QuickBooks Online only uses one Chart of Accounts per subscription. While you're not able to set up a completely separate Chart of Accounts, you can add or edit the existing one by following these steps: Add to or edit the Chart of Accounts.

If you're trying to set up a new bank account in QuickBooks, you can do so through the Chart of Accounts. This account will be used to track all the transactions you post to this account. 

You can also sync multiple bank accounts to the Bank Feed. This tool allows you to automatically upload transactions from your bank account each night. Here's how to do that: Connect bank and credit card accounts to QuickBooks Online.

I hope this helps to answer your question. If there's anything else I can do to help, please let me know. 

Have a great day.
