but your talking about your industry.  In my industry, we sign a large contract and slowly do the work over a period of months or years and the payments have to be applied to this "invoice"  We actually do not send out that invoice but use it to keep track in QB of the payments and the balance owed.  Recently QB started "progressive" invoicing which I switched to but now I have a lot of open invoices that should be "estimates" but are really signed contracts.  so my boss wants me to use this feature.  I want to put the balances on all the contracts into the estimate area and pay the balances off as we are paid.  However,  I have two concerns...(1)  am concerned if this is going to impact our accrual method of reporting.  Are these balances in the estimates going to show up on our P&L?  and (2) is the only way to make these invoices into estimates by deleting the invoices and redoing the entire database?  (of course, #2 is irrelevant if we are not going to be counting the balances of the signed contracts as accruals in the reports).
