We are a construction company also and it doesn't matter which report you run, the costs are ALL wrong! I spent an hour on the phone and sharing my screen only to be told that "this is how it works and nothing is wrong". BULLSH*T!!! I've used desktop for years and this was NEVER an issue. 

If one of my guys works 3 hours on a job, the Job Profitability Report AND the Project screen where costs are shown are pulling in his entire paycheck amount for the week. Also, if I enter a Home Depot statement and break out each item and cost it to a job, the JPR shows the ENTIRE Home Depot statement amount on each and every job I've broken out.

Not sure where to go from here. The owner hired me to get his job costing up and running and although I've done my job, QB isn't doing theirs and we pay a fortune to have this all up and running properly. I can't even show him a P&L by Job because it's ALL wrong!!!!!!!!
