I'm working in QuickBooks Enterprise Professional.  We purchased professional hoping we can do progressive invoices but it's so convoluted it's not worth it so although I've been putting in the full amount of contracts, I've just been posting the payments from invoices we send separately.  We cannot invoice from QB because these are government invoices that are sometimes 14 pages long.  The problem.  I now have open invoices form 2016, 2017, 2018, and 2019 and they are incorrect making my P&L incorrect.  How do I get rid of these invoices.  I'd like to delete or transfer all the invoices back to estimates and apply invoices with a correct balance at the end of each month for 2020 so reports are correct.  I have a spreadsheet with the contract amounts and have kept it going all year so I have the correct balances on the contracts.  Is this possible or do you know of a qB accountant that can show me how to do this?
