EstimatesPlease 1.2.0.1   
by Berdwire   

If you make client estimates, estimate current or future sales, estimate amounts of items or go through complex "what if?" scenarios then EstimatesPlease is the calculator for you. Just enter what you know for an estimate. An approximate amount? No problem. An iffy sale? Same thing. Just click = and you have your "lowest-possible-case" estimate, your "highest- possible-case" estimate and everything in between. With EstimatesPlease, you don't need any hard-and-fast numbers or equations for a solution!
