There is no way to "Delete Multiple Transactions" i.e. Sale Invoices, Bills, Other Transactions etc. in one go in QBO, and user has to Open each transaction to Delete, which is really a time taking task depending on the volume of data.

So the idea is there should be an Option through which a User can "Select Multiple Transactions/Entries" and can Delete all the Selected Transactions in one go. It will be efficient for the User with minimum wasted efforts. Thanks.
