About this app

Smart Bid Estimate Calculation — Simulate the estimated price and bid amount for KONEPS electronic bidding right on your mobile device.

Simply enter the base price and the estimate range, and it will generate 15 preliminary prices using the Public Procurement Service's multiple preliminary price method. It will then calculate the estimated price by drawing and averaging four of these prices. Additionally, it applies the minimum bid acceptance rate (bid rate) to calculate the bid amount in a single step, and allows you to output the results as a PDF report.
