went from sq ft pricing (where we had been for almost 40 years) to room pricing in 1982. Huge increase in production times for jobs that had no estimator come out beforehand, saved the commission/car/gas/maintenance for the estimator for jobs that did have her out, and the customers could have an accurate price and book the cleaning job right over the phone. At the time we were doing between 50-60 jobs a day and now 160-200.
