Here it is the end of the year and my invoices are a mess.  I don't understand how to get the progressive invoices going.  I kept running balances on the contracts in a spreadsheet deleting payments and have correct balances in the spreadsheet.  at this point I'd like to delete all the invoices and go month by month creating an invoice and paying it or just deleting all the invoices and apply balances on the 25th of December so the P&L for 2020 shows the correct balances in a financial report.  However, this last fix will not work if we run a P&L at anytime during any month of last year so deleting and putting them in on a monthly basis seems the best opetion if I can do that.
