List four factors that should be considered before selecting a supplier.

1. Quality of products or services: It is important to ensure that the supplier can provide high-quality products or services that meet your standards and requirements.

2. Reliability and reputation: Consider the supplier's track record in terms of delivering orders on time, resolving issues promptly, and maintaining a good reputation in the industry.

3. Cost and pricing: Compare the pricing of different suppliers to ensure that you are getting a competitive rate for the products or services you need. However, it is also important to consider the overall value and quality provided by the supplier, rather than just focusing on the lowest price.

4. Location and logistics: Consider the supplier's location and logistics capabilities, as this can impact shipping costs, delivery times, and overall efficiency in the supply chain. It may be beneficial to choose a supplier that is geographically close to your business to reduce transportation costs and lead times.

1. Quality and reliability: Assess the supplier's track record for delivering high-quality products or services, and their ability to meet delivery deadlines and specifications.
2. Cost and pricing: Compare the supplier's prices with those of other potential suppliers, and consider factors such as discounts, payment terms, and any hidden costs.
3. Capacity and lead time: Determine if the supplier has the capacity to meet your demand, and if their lead times align with your production or operational schedule.
4. Reputation and references: Research the supplier's reputation in the industry, and ask for references from previous customers to gain insights into their performance and reliability.
