You do have several ways you can do this in Estimator – regarding hourly rates. Two examples – let’s say you have a $400 window component and you pay your installer $50 to install that window. You could then use COMPONENT tab and assign the unit price for the column ($400) (attribute of QUANTITY – default) and unit of EA – then click on the + button to create a new cost entry and keep attribute of quantity – use *(# of hours) in the multiplier, unit rate for labor and HRS (or whatever you use) in the units displayed – save.
Then each similar window component you select will total $450 – pick two and it is $900, etc.
OR – you could use Quotes if you want to to enter unit rate and number of hours.
Hope this helps and please let me know if you have any other questions.
