Category Management and Performance Services
Turning decades of on-the-ground experience into commercial advantage.

Built on more than 20 years of global inspection and technical expertise, GQS combines real-world supplier insight with procurement and category expertise. Our integrated approach helps organisations improves cost, margin, supplier performance and supply chain resilience.
Unlike traditional procurement consultancies, our recommendations are informed by insight gained through decades of inspection and technical assurance activities across global supply chains. This enables customers to identify opportunities to unlock value across the supply chain, while maintaining the highest standards of quality, safety and compliance.

Procurement Transformation
GQS helps organisations redesign and strengthen procurement functions to improve commercial performance, resilience and long-term value creation.
We begin with a free Discovery Assessment that establishes a clear baseline of spend, supplier risk, savings opportunities and ESG performance before developing a practical roadmap for improvement.
Rather than relying on generic frameworks, we can provide our Discovery Assessments within weeks, mapping, cleansing and categorising both direct and indirect spends.
Following our Discovery Assessment, our services include:
- Spend and supplier diagnostics
- Procurement operating model design
- Source-to-pay maturity assessments
- ESG and carbon baseline development
- Make-versus-buy analysis
- Localisation and near-shoring strategies
- Cooperative buying programmes
