Improving the cash-to-cash cycle time involves reducing the time taken to convert resources into cash flows. Implementing vendor-managed inventory (VMI) with key suppliers can significantly improve this cycle by reducing inventory holding costs and improving inventory turnover. In a VMI setup, suppliers manage the inventory levels of their products at the customer's location, ensuring optimal inventory levels and reducing stockouts and excess inventory. This arrangement improves cash flow as it reduces the amount of capital tied up in inventory. Finding suppliers with lower TCO, implementing VMI with customers, or targeting promotions, while beneficial, do not have as direct an impact on the cash-to-cash cycle time as VMI with suppliers.
