Good morning, @lisa jm53.
Thanks for taking the time to reach out to the QuickBooks Community. I hope you're having a great day so far.
When you change your preferences to Cash basis, all Company and financial reports will default to Cash basis except the Details reports (Profit & Loss Detail, Income by Customer Detail, and Balance Sheet Detail).
I understand how beneficial it is to have all reports show on a cash basis for you and your business. Since this isn't an option for all reports in QuickBooks Desktop, I will personally submit this feedback directly to our Product Development team for consideration in future updates.
QuickBooks is constantly evolving and I can assure you that our customer's voice does matter. I encourage you to submit feedback as well. Here's how:
1. At the top menu bar, go to Help, then choose Send Feedback Online.
2. Enter your request/product suggestion, then select Next.
3. Tap on Skip, then send a message, and choose Feedback as the Category.
Please don't hesitate to let me know if you have any additional questions or concerns. Have a good one!
