From the unbilled charge report there are a number of transactions from years ago where we need to untick the billable field as the costs are never going to be billed.  We can then archive the customers and unused nominal codes.  The issue is that when we transferred to QBO it has some VAT codes that are no longer valid or even on the tax code list.  How do we clear these off the unbilled charges report without messing up the current VAT?  Any help greatly appreciated,  Thanks  Lisa
