What is an estimator?
An estimator is the person who prices jobs and builds bids. The U.S. Bureau of Labor Statistics describes cost estimators as collecting and analyzing data to assess the time, money, materials and labor a job requires, and notes that they work with sales teams to prepare bids. In commercial services, estimators may walk sites, take quantities off drawings and set the labor assumptions that decide margin.
Why it matters to a revenue leader
The estimator controls two things a revenue leader cares about: how many bids the company can submit and how profitable the won work will be. Estimating capacity is often the real limit on bid volume, so adding sellers without adding estimating capacity produces slower bids and lower hit rates. The seller and estimator relationship matters as much as either person's skill. Sellers bring customer context and competitive intelligence; estimators bring cost reality. When they work apart, the company wins the wrong jobs at the wrong price.
Example
A fire protection company with 10 sellers and two estimators sees bid turnaround stretch to three weeks. Bid-hit rate falls as faster competitors reach the GC first. The revenue leader adds a third estimator and asks sellers to qualify each opportunity before it enters the estimating queue.
"How long does a bid wait in the estimating queue, and how many bids did we decline for lack of capacity?"
