This study contains several tools that can be used to compute losses due to out-of-stocks as well as a calculator of the payout that can be expected when addressing out-of-stocks. To access the payout calculator, click here. This calculator provides the ability to play what-if scenarios in terms of how many products and stores they want to work on and which of the solutions they want to employ. No matter what, the payout is exceptional.
