After enter about 15-20 different jobs into Quick Books and running a couple of reports to view my companies performance I have found some issues that I don't know how to solve. When I run the financial report by job, about 3-4 of the jobs have a negative number for the cost of materials. This number is then added to the revenue, aka money the customer paid me for the job. However when I ran a different report, expenses by job it shows all of the bills being paid with the correct amounts. There are no over payments of any bills so I do not know where the negative number came from. The odd thing is when you look at the profit from the two different reports, they are the same amount! Any ideas?
