Short description of Estimate 2.02.01: Estimate is a generic costing and estimating system suitable for any trade or profession. You create a price list. You create a simple estimate by choosing items from your price list and inserting the quantity. Once estimates have been saved, they in turn can be chosen as items in later estimates. When prices change, you just update your price list and your estimates are recosted with the latest prices next time you load them.
