I got your back on your query about adding a bank account to the Chart of Accounts in QuickBooks Online (QBO), @PARKSG.

The Bank account type is available for QBO Singapore. Since you don't see the option, I suggest you open your browser's private window first. This will allow you to isolate cache, which is usually the cause of unusual behaviors in browsers. 

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge: Ctrl + Shift + P
• Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N

If that works, go back to your regular browser and clear its cache. Otherwise, open an alternative browser that's available for you. 

When you're done creating the bank account, if you decide to sync your bank to QBO, follow the steps in this article: Connect bank and credit card accounts to QuickBooks Online.

Tag me in a comment below if you have other questions about creating accounts in QBO. I'll get back to you as soon as I can. Have a pleasant day!
