Thanks for reaching out to us here in the Community. I can help change the accounting method in QuickBooks Online (QBO), Not_a_CPA.
There's no option to set an accounting method for the reports since it will be based on your company's accounting method. With that said, I suggest toggling it from Accrual to Cash and then back. You'll need to manually change it and I'd be glad to help you with this.
- Select Settings ⚙, then select Account and settings.
- Go to the Advanced tab.
- In the Accounting section, select the Edit ✎ icon.
- Choose the Accounting method.
- Select Save, then Done.
Once done, pull up the report to double-check. Please know that the information showing on your Dashboard depends on the Accounting method you use or set up on your company settings.
