Our company is also having the same issue with missing sales orders from the Open Sales Order Report by Customer. Support has been contacted, all fixes have been attempted. For a sales order we knew was not fully invoiced but missing from the report, we simply made a small change that was non financial and saved. Then the sales order would suddenly appear in the open sales report when previously it had not. Its continuously happening that we now feel the data integrity is flawed. Can QuickBooks please address this issue or advise what is recommended at this point?  We cannot operate a business using unreliable software.
