Understanding the Different Types of Technology Suppliers
Selecting the right technology supplier is one of the most consequential decisions a business can make. The technology landscape is complex, with a wide range of supplier types offering overlapping but distinct propositions. Understanding the differences between these supplier categories is essential for making informed procurement decisions, negotiating effectively, and managing supplier relationships over the contract term.
Too many organisations default to familiar suppliers or accept vendor-led recommendations without fully evaluating the alternatives. This can result in paying more than necessary, accepting solutions that do not fully meet requirements, or locking into commercial arrangements that limit future flexibility. A structured approach to technology supplier evaluation, grounded in a clear understanding of supplier types and their relative strengths, reduces these risks and improves outcomes.
Whether you are procuring hardware, software, managed services, or a complex integrated solution, the choice of supplier type will significantly influence the cost, quality, flexibility, and risk profile of the engagement. This guide sets out the main categories of technology supplier, the advantages and limitations of each, and a practical framework for evaluating and selecting the right partner.
Original Equipment Manufacturers (OEMs)
OEMs design, develop, and manufacture technology products. In the IT sector, this includes server hardware, networking equipment, storage systems, operating systems, and enterprise software platforms. Buying directly from an OEM gives you access to the manufacturer's full product range, technical support, product roadmap information, and often the most competitive pricing for the specific products in their portfolio.
However, OEMs are not always the most cost-effective or most appropriate route to procurement. Their commercial focus is on selling their own products, which means the recommendations you receive will naturally be weighted toward their portfolio rather than the best solution for your requirement. OEM pricing structures can also be complex, with list prices, volume discounts, licence tiers, maintenance bundles, and renewal terms that require careful analysis to ensure you are getting genuine value. For organisations without deep technical procurement expertise, engaging with an OEM directly can result in over-specification or commitment to products that do not align with long-term strategy.
OEMs are best suited for situations where you have already defined your technical requirements and are confident that a specific product range is the right fit. For more complex requirements where the solution is not predetermined, other supplier types may offer a more objective approach. For a structured approach to defining IT requirements before engaging suppliers, see our IT procurement strategy guide (/post/it-procurement-strategy-a-6-step-process).
Value Added Resellers (VARs)
Value Added Resellers purchase products from OEMs and add value through services such as configuration, installation, integration, training, and ongoing support. VARs often hold partnerships with multiple OEMs, which in principle allows them to recommend the most appropriate solution from across several product ranges rather than being limited to a single manufacturer's portfolio.
The value in working with a VAR lies in their ability to combine products from different manufacturers into a coherent solution, provide local implementation and support services, and offer a single point of commercial and contractual accountability. For mid-sized organisations that need a complete solution rather than individual products, a good VAR can simplify the procurement process significantly by managing the complexity of multi-vendor integration.
The risk with VARs is that their recommendations may be influenced by their partnership agreements, margin structures, and vendor incentive programmes rather than purely by your requirements. Understanding which OEM relationships a VAR holds, how those relationships affect pricing and recommendations, and whether the VAR has genuinely independent advisory capability is an important part of the evaluation process. Ask for evidence of occasions where the VAR has recommended a product outside their primary partnerships because it was the better fit for the client's needs.
Managed Service Providers (MSPs)
Managed Service Providers take operational responsibility for defined IT functions or infrastructure, typically under a long-term contract with agreed service levels. Common managed services include network management and monitoring, security operations and incident response, help desk and end-user support, cloud infrastructure management and optimisation, and backup, disaster recovery, and business continuity.
The commercial model for MSPs is typically subscription-based, with monthly or annual fees covering agreed service levels. This model provides cost predictability and allows organisations to access specialist technical skills without building permanent in-house capability. For many SMEs, an MSP provides enterprise-grade IT management at a fraction of the cost of building an equivalent internal team.
The key considerations when evaluating MSPs are the clarity and enforceability of the service level agreement, the provider's track record in delivering against those service levels over time (not just in the sales process), the transition approach for migrating your existing environment into the managed service, and the exit provisions if the arrangement does not meet expectations. On-boarding and transition are frequently underestimated in managed service engagements. A provider that offers a low monthly fee but requires an expensive and disruptive transition may not represent the best value overall.
Our guide to IT procurement: how to choose the right supplier (/post/it-procurement-how-to-choose-the-right-supplier) covers the detailed evaluation criteria for managed service providers and other technology supplier types.
System Integrators
System integrators specialise in bringing together multiple technology components, often from different vendors, into a functioning, tested, and deployed solution. They manage the complexity of integration, data migration, testing, and deployment that would otherwise fall on the customer to coordinate across multiple separate suppliers.
For organisations undertaking digital transformation, ERP implementation, cloud migration, or large-scale infrastructure refresh projects, system integrators provide the programme management and technical expertise to deliver complex multi-vendor solutions. The system integrator takes responsibility for ensuring that the individual components work together as a coherent system, which is often the most challenging and highest-risk element of a technology programme.
Working with a system integrator involves higher costs than direct product procurement, but the value lies in their ability to manage technical and delivery risk, coordinate multiple workstreams and vendor relationships, and deliver a solution that meets business requirements rather than simply technical specifications. For large-scale transformation programmes, the cost of not using a system integrator, in terms of integration failures, delays, and rework, typically far exceeds the cost of the integrator's fees.
Understanding what is IT transformation procurement and the challenges involved (/post/what-is-it-transformation-procurement-what-are-the-challenges) provides important context for organisations considering this route.
Software as a Service (SaaS) Vendors
SaaS vendors deliver software applications over the internet on a subscription basis. This delivery model has become the dominant approach for business applications including CRM, HR, finance, collaboration, project management, and increasingly specialist functions such as procurement software (/technology/procurement-software), contract management software (/technology/contract-management-software), and spend analytics (/technology/spend-analytics-software).
The commercial advantages of SaaS include lower upfront costs compared to on-premise software, automatic updates and maintenance handled by the vendor, scalable capacity that grows with your organisation, and reduced internal IT support requirements. SaaS solutions can typically be deployed quickly, often in days or weeks rather than the months required for on-premise installations.
The procurement considerations for SaaS are distinct from traditional software purchasing. Data sovereignty and security are critical: where is your data held, under which jurisdiction, who can access it, and what happens to it if you leave the service? Contractual terms around data portability and exit need careful scrutiny because migrating away from a SaaS platform can be significantly more complex and costly than the initial adoption. Integration with existing systems should be tested rather than assumed, as API capabilities vary significantly between vendors. Total cost of ownership over the subscription term, including any per-user, per-module, or per-transaction charges, must be compared against alternatives to ensure the subscription model genuinely represents value.
Consultancies and Advisory Firms
Technology consultancies provide strategic advice, requirements analysis, vendor selection support, and programme oversight. They do not typically sell or implement products directly, instead offering independent guidance to help organisations make better technology decisions.
The value of a consultancy engagement is in the independence of the advice. A good technology consultant will evaluate your requirements objectively, assess the market without bias toward specific vendors, and help you develop a procurement strategy that delivers the best outcome for your organisation. This is particularly valuable when the requirement is complex, when you are entering an unfamiliar technology area, or when the procurement involves significant expenditure and risk.
At Athena, our procurement consulting service (/services/procurement-consulting) covers technology procurement alongside broader procurement strategy, combining commercial expertise with practical experience of public and private sector technology markets. We supported BDR Thermea through a £20 million IoT procurement process (/case-studies/ps20m-iot-procurement-process-led-for-bdr-thermea) and have delivered multiple successful technology-related framework registrations for clients.
How to Evaluate Technology Suppliers
Regardless of supplier type, effective evaluation requires a structured approach. Without clear evaluation criteria applied consistently across all options, procurement decisions risk being driven by the most persuasive sales presentation rather than the best fit for the requirement.
Technical capability and solution fit is the starting point. Does the supplier's offering genuinely meet your requirements, or will it require you to adapt your processes and expectations to fit the product? The best solution is the one that solves your problem, not the one with the most impressive feature list. Proof of concept or pilot deployments are valuable for validating technical fit before committing to a full procurement.
Commercial terms should be evaluated carefully, covering total cost of ownership over the contract term (not just the headline price), pricing transparency and predictability, flexibility to scale up or down, and exit provisions including data portability, transition support, and any termination penalties. Our contract reviews service (/services/contract-reviews) can help you assess the commercial terms offered by technology suppliers.
Track record and references are essential. Ask for case studies from organisations of similar size and complexity to yours, and where possible speak directly to reference clients. A supplier that performs well for enterprise clients may not be the right fit for an SME, and vice versa. Ask about implementation timelines, support responsiveness, and any challenges encountered during the engagement.
Support and service levels need to be clearly defined and backed by meaningful service level agreements with appropriate remedies for non-performance. A 99.9% uptime commitment is meaningless without clear definitions of what constitutes downtime, how it is measured, and what compensation applies when the target is missed.
Financial stability matters because a supplier that is financially unstable represents a risk to continuity of service. For critical systems, conducting basic due diligence on the supplier's financial health is a prudent step.
