It’s absolutely essential for you to have accurate job costing so you can easily see what jobs and clients are profitable, and which ones are not. By focusing on eliminating unprofitable jobs, and growing the profitable ones, dramatic improvements in overall company profitability in your shop are possible.
The problem with job costing in most ERP systems is that they are cumbersome to keep accurate and even to look up job costing. The result: you don’t use them, and therefore have no idea beyond a gut feel of which jobs are profitable and which are losers and need to be improved. This lack of clarity is a major factor in inconsistent profitability.
