The first question is are you quoting new or existing parts? If existing, then your FIFO costing method will cost you jobs. We use FIFO as well and using expected cost could hide the fact that your production has improved over time unless you have an aggressive program for updating NAV to reflect reality. I quote outside of NAV because it allows me to use averages over a period of time.
This is especially useful for new jobs that are the same as except because I can pull data from a whole family and use those run rates to predict how long the new job should take. The scrap factor can also be averaged and applied.
This conversation is very interesting to me. I try to do everything within NAV, but I just can't find a great way to use it for quotes. If you come up with a great method please share.
Good luck.
