As I explained in your original question here: https://accountants-community.intuit.com/questions/1896747-onboarding-clients-to-qboa-cash-or-accrua...

The QB reporting will cover every perspective.

What will happens is that running Cash Basis reports for this entity with balance sheet activity means the activity will always show. Example: you use Receive Payment against a customer with no open AR balance (an error), which creates negative AR for accrual basis reporting. On cash basis reporting, you will see this as Uncategorized income, because it is required to show it for Banking purposes to be correct. Otherwise, a credit memo or invoice that creates AR does not typically show in Cash Basis reporting, but will show in both cash and accrual basis, when the sales or credit includes inventory or sales tax, because both of these are Balance Sheet (inventory asset and sales tax liability) activities.
