Frequently Asked Questions
What is the difference between a supplier and a vendor?
In everyday business English the two words overlap a great deal. A supplier usually refers to a company that provides the raw materials, parts, or goods that another business needs to make or sell its own products. A vendor is anyone who sells goods or services, and the word is often used for the same companies a buyer purchases from. As a rough rule, you might call a long-term partner who feeds your production line a supplier, while you might call a one-off or smaller seller a vendor, but in practice the terms are frequently used interchangeably.
What does procurement actually involve?
Procurement is more than simply buying things. It covers identifying what the business needs, finding and comparing suppliers, negotiating prices and contracts, placing the order, and managing the supplier relationship afterwards. A good procurement team aims to secure the right quality at the right price while keeping the supply chain reliable. In larger companies procurement is a whole department, and it works closely with finance, operations, and the warehouse teams.
Why is lead time so important in the supply chain?
Lead time is the gap between placing an order and actually receiving the goods. It matters because it determines when you must reorder to avoid running out. If a supplier has a long lead time of six or eight weeks, you have to plan and order well in advance, and you may need to hold more stock as a buffer. Short, reliable lead times let a business keep less inventory and respond quickly to changes in demand, which saves money and storage space.
What is inventory and why do companies track it so carefully?
Inventory is all the stock and materials a company holds, from raw components to finished goods waiting to be sold. Companies track it carefully because inventory ties up money and takes up space. Too much inventory means cash is locked away in goods that are not selling, while too little can lead to running out and disappointing customers. By monitoring the stock level of each item, a business can order just enough to meet demand without overstocking the warehouse.
What does just-in-time mean?
Just-in-time, often shortened to JIT, is an approach in which materials and parts arrive exactly when they are needed in the production process, rather than being stored in advance. The aim is to keep inventory and storage costs as low as possible. The trade-off is that the system depends on reliable suppliers and short lead times; if a delivery is late, production can stop because there is no spare stock to fall back on. Many factories balance just-in-time with a small safety buffer to manage that risk.
What is a bottleneck in operations?
A bottleneck is a stage in a process that cannot keep up with the rest, so it slows everything down. The image comes from the narrow neck of a bottle, which limits how fast liquid can pour out. In a warehouse, a single packing station might be a bottleneck if goods pile up waiting to be packed. Identifying and fixing bottlenecks, perhaps by adding staff or equipment, is one of the most effective ways to increase throughput and speed up the whole supply chain.
What is the difference between logistics and distribution?
Logistics is the broad term for organising the movement and storage of goods across the whole supply chain, including transport, warehousing, and inventory. Distribution is a narrower part of logistics that focuses specifically on getting finished products out to shops or customers. You could say distribution is one important branch of logistics. Both involve careful planning so that goods reach the right place, at the right time, in the right quantity, and at a reasonable cost.
What does the last mile refer to?
The last mile is the final stage of delivery, when a product travels from a local depot or hub to the customer’s home or business. Despite the name, it is not always exactly a mile. It is often the most expensive and difficult part of the journey because deliveries are spread out, traffic in towns is slow, and customers may not be in. Companies invest heavily in last-mile solutions, such as parcel lockers and route-planning software, to keep delivery fast and affordable.
What is demand forecasting and why does it matter?
Demand forecasting is the practice of predicting how much customers will want to buy in the weeks or months ahead. It draws on past sales, seasonal patterns, and market trends. Accurate forecasting matters because it drives almost every other decision in the supply chain: how much to order from suppliers, how much stock to hold, and how many staff to schedule. Poor forecasting leads either to empty shelves and lost sales or to costly surplus stock that has to be discounted to clear.
What is the best way to learn supply chain vocabulary?
The most effective approach is to link each word to a real stage of the supply chain. Picture an order moving from procurement, through the warehouse as inventory, into distribution, and out on its last mile to the customer. Reading industry news and company logistics reports will show the words in natural use. Practise the 20 terms on this page with Flash Cards on LexFizz, then test yourself with the Quiz.
