How do I categorize when I participate in a seminar, conference related to a business

Hm that doesn't seem to be an option on my QB Online... :-(

I'll help you create an expense account in your QuickBooks Online (QBO), @CANUK.

Let's go to the Accounting menu and create an account from there.

Here's how:

1. Go to the Accounting menu, and select Chart of Accounts.
2. Select New to create a new account.
3. In the New account window, select Expenses as the account type.
4. From the Save account under field, select Other Business Expenses.
5. Fill in the needed details and select Save when done. 

You can also see this article for more details about this: Add an account to your chart of accounts in QuickBooks Online.

I'd also encourage consulting with your accountant for guidance in choosing the correct account and to steer away from any errors.

Once you're all set, you can now create an expense using your expense account. Please see this article for your reference: Enter and manage expenses in QuickBooks Online.

I'll be around to assist you if you need more help managing your accounts and expenses in QBO. Keep safe and more power to your business!

Thanks for this but that isn't the same as what I'm seeing in my QBO... See attached screenshot.

The layout is different and the closest to 'expense' I have is "expenditure". Under which, the other business cost isn't an option.

Any help appreciated - and why my QBO seems to look very different from yours!

Thanks for trying that, CANUK.

I don't see an attached screenshot, so I'm not sure how things look on your side. Just to make sure, are you using a different version of QuickBooks Online, such as an accountant subscription or QBO for a different country?

You may want to try the screenshot once more, or if you'd like to call in, agents have the ability to share your screen to determine exactly why you are seeing a difference in your QuickBooks Online account. Here's how to get in touch with the team:

1. Click the Help button in the top right corner.
2. Select Contact Us.
3. Enter Support in the field and choose Let's talk.
4. From here you can select to receive a callback at a time that's convenient for you, or begin a live chat session with an agent.
