What is the supply chain?

We explain what the IT supply chain is and what each role has when choosing and implementing new technologies in the workplace

Supply and demand graph

The supply chain refers to the process in which goods and services are delivered to end users, including manufacture, distribution and physical delivery to the customer.

However, unlike traditional supply chains in retail, for example, the delivery of IT systems and services to customers doesn't rely on logistics as such, but the role of resellers, distributors and services providers and consultants to ensure the end user (the company) has the right infrastructure to meet its business needs.

Although logistics does apply if we're talking physical equipment, such as servers, computers, printers and other peripheries, the majority of IT sales are now digital, which means there isn't a physical handover of equipment, but more likely a company that will liaise with the end user to get the software or platform configured in the way it should be to benefit the business.

Direct vs. indirect distribution

At the top of the chain is the manufacturer of the product, whether it's the physical equipment or the software. This, in the IT supply chain has become known as the vendor'.

The vendor may decide to sell its products directly to the customer, in which case an in-house sales team from the vendor will directly communicate with the business to deliver the solution and set it up in the way. It means the vendor will need to invest in the training and sales staff in order to sell directly to end users.

An account manager will normally oversee this in the vendor organisation, building up a relationship with the business' point of contact - such as the IT manager or IT director who usually deals with the procurement of new equipment and software for the organisation.

However, if a vendor an also decide to go down the indirect channel route, using a partner network to sell into the company (end user) and this is where it gets a little more complicated.

Supply Chain Management

Supply chain management handles the entire flow of goods and services through the chain. It not only includes the physical movement of goods from their raw materials, through to production and onto the end user, it also handles the inventory too, making sure there's enough product to fulfil orders.

The process of supply chain management uses inspiration from various engineering processes, including industrial engineering, systems engineering as well as operations management, logistics, procurement, information technology and marketing.

It relies on both physical and information flows, ensuring everyone involved in the supply chain knows exactly what's going on at every stage to ensure products and services arrive with the customer in the most efficient way. This means there's a big focus on customer experience too and this can be communicated through marketing channels throughout their contacts with the business.

Although there are multiple components to effective supply chain management operations and much debate about what should be included, the most recognised include planning and control, organisational structure, product and information flow, management methods, power and leadership structure and rewards.

However, there are numerous interpretations about what supply chain management actually is and how it should be used in the most productive way to get shipments to customers.

What is clear is that the management of the supply chain is a constantly-evolving process, with businesses needing to be adaptive and flexible to meet the changing needs of the customer.


A distributor will work with a number of resellers (see below) to distribute products around the world. It will take the products from the vendor and work with resellers to distribute the products to the end user.

The distributor builds up a relationship with the resellers to help them make more sales to end users, offering the resources they need to make each sale a success. That could be through training, marketing or other areas that will ensure resellers are marketing and selling the product as widely as possible.

It's likely a distributor will supply the reseller with a range of products from different vendors rather than just sticking to one, giving the resellers a much better market coverage and therefore making them more attractive to end users. If a business knows they can buy multiple solutions from one reseller, it will save them time dealing with


A reseller takes the products from the distributor and sells them on to end users, acting as a middle man.

Buying from a reseller has a distinct advantage over buying direct from the manufacturer - they are able to tag on extra services or products the company may also find useful as value-adds'. This could include the software to go with the equipment, or it could include complementary services to make sure the business gets the most out of their applications.

It also means the business will have a much wider variety of vendors to choose from compared to choosing to buy products directly from the vendor.

Systems integrator

If a business wants to outsource the implementation of its IT systems and software, it can choose to use a systems integrator that will buy the different components from a number of different resellers on its behalf and then integrate' them into the business, without the IT department having to worry about having the resource or expertise to do so.

Using a systems integrator means a business has the reassurance that everything will work seamlessly together, and because a systems integrator is usually able to offer managed services, blurring the lines between them and a standalone MSP,  businesses can ensure everything from choosing the technology to use, implementing it and the after sales support is all present and correct.
