The benefits are derived to estimate the net cash flow when investing in the Replenishment Inventory System. It is found that the Economics order Quantity (EOQ) method can reduce the total cost of ordering and cost of inventory averaging 4.6% per year. The analysisof financial value by using Replenishment Inventory System, considering on the Payback period Method ;PB, Net Present Value ;NPV, Internal Rate of Return ;IRR, Benefit Cost Ratio ;BCR, Return on investment ;ROI and Switching Value Test, is found that the PB is less than expected.NPV is greater than zero, BCR is greater than one, ROI is 21% and IRR is higher than expected. The expected return is 4.5 %. The return can reduce 15% before NPV turns to zero, meanwhile Cost of investment can increase 17% before NPV turns to zero.Therefore,Replenishment Inventory Systemshould be used by the retailersfor inventory management.
