Is it possible to change the P & L reporting in the app from cash to accrual basis?

Hi iantowsey-t3engi,

Thanks for posting in the Community!

At the moment, it is not possible to change the reporting method in the app. QuickBooks Online mobile app is a simplified version of the QuickBooks program. Some features aren't available in the mobile app. To change the reporting method from cash to accrual, you'll need to login on a web browser.

Here's how:

1. Go to Reports.
2. Search for Profit and Loss.
3. Select Cash or Accrual under Accounting method (you can also select the Customise button to open the Customise Report window and change the setting in the General section).
4. Select Run report.

Also, you can change the reporting method on your QuickBooks settings.

Here's how:

1. Select Settings, then select Account and settings.
2. Go to the Advanced tab.
3. In the Accounting section, select Edit icon.
4. Choose the Accounting method.
5. Select Save, then Done.

For more detailed information, you can check on this article: Choose between cash and accrual accounting methods in reports.
