QBSE. How to I reduce the Business Income in SE to show a customer refund? Can anyone advise please> TIA

Hello Deborah9,

Thanks for joining the QuickBooks Online Community. 

To do this, you will need to create an expense transaction by selecting an expense category on the transaction line to show the money going out of the account. There is not a specific category for refunds, you could use 'other business expense' for this however this will depend on whether the expense is allowable or disallowable. We'd advise to check with you're accountant if you are unsure of which specific category to use :)
