It is important to invest in technology that will best meet your needs.
Analyze your estimators' tasks. Often, they go far beyond quantity takeoffs. How much do they communicate with the field? Do they order material for each job? Do they project future needs for inventory or for supplier price breaks? How about cost-coding the job for the accounting department? Good systems can make these tasks much faster, freeing the estimator from crunching numbers and allowing more time to analyze the job.
