What's the impact of discounts on inventory turnover rates?

As an e-commerce manager, I'm struggling to understand how strategic discounting impacts my inventory management. I need to know whether offering discounts actually helps me move slow-moving stock more efficiently or if it simply erodes my profit margins. My current approach feels reactive, and I want to develop a data-driven strategy that balances liquidating excess inventory with maintaining healthy profit levels. What metrics should I track, and how can I use discounts as a precise inventory optimization tool?
