Is there a way to access expenses over 12 months old in the app? That's as far back as the drop down menu will allow me.

To review your expense transactions from the past year or longer, please log in to your QuickBooks Online (QBO) account using a web browser, roj_9, as accessing it through the mobile app is not an option.

You can use this link to access your account and enter your login credentials. After logging in, follow these steps to view your expense transactions:

1. In the left menu, click Expenses then go to the Expenses tab.
2. Click the Filter button.
3. Set the necessary filters.
4. Click Apply. 

That’s it! You will now see your previous expense transactions.

To know more how to handle your expenses via web browser in QBO, you can check this article for a guide: Enter and manage expenses in QuickBooks Online.

In addition, if you want to plan to pay your expenses in the future, you can enter them as a bill.
