What are disadvantages of just in time purchasing?

Just-in-time (JIT) purchasing can lead to several disadvantages, including increased vulnerability to supply chain disruptions, as there is minimal inventory on hand to buffer against delays. It also necessitates strong relationships with suppliers, which can be challenging to maintain and may result in higher costs if suppliers raise prices. Additionally, JIT systems can limit a company's ability to respond quickly to unexpected spikes in demand, potentially leading to lost sales. Lastly, the pressure on suppliers to deliver precisely on time can lead to quality control issues if not managed carefully.
