Hi, simple. Qbo plus if setup in settings to use any of two features, the fifo (first in first out ) or average cost feature, then the field in product/item becomes inactive ( you can enter anything there if you want or leave it at zero, because qbo plus calculates the costs. Yes,It needs to show these calculated costs to users during invoice, eatimate creation. However,You can see this calculated cost, just enter all items in estimate or invoice, click save, then in "more options" at bottom bar click transaction journal ? Or something like that it's called. I use this info and go back and change sales prices manuay. Yesss... We need markup feature. Every product category its own mark up setup.
