Procurement & Sourcing: 5 Key Terms

By Devon Coombs, CPA, MBA · Teaching Professor of Finance, Santa Clara University · Reviewed August 2026

Procurement and sourcing describe how organizations decide what to buy, from whom, and on what terms, extending finance work into the supply side of the business. The vocabulary ranges from strategic frameworks such as category management and the purchasing portfolio matrix to analytical tools such as the should-cost model, which estimates what a purchased item ought to cost based on its underlying inputs. Concepts like best value and tail spend matter because sourcing decisions are rarely settled on price alone, and small unmanaged purchases often accumulate into meaningful cost. Learners in the free Applied AI for Finance and Accounting course apply these terms when using AI to analyze spend data and evaluate supplier economics.

These terms are taught in Appendix: Procurement and Sourcing of the free Applied AI for Finance and Accounting course; the full course glossary collects every chapter in one place.

Best value

The award decision that weighs total cost, quality, and risk rather than lowest price alone.

Category management

Managing related spend as a portfolio with a tailored strategy per category, rather than buying transaction by transaction.

Purchasing portfolio matrix

Kraljic's framework classifying spend by profit impact and supply risk to set a sourcing strategy for each category.

Should-cost model

An independent, bottom-up estimate of what a product should cost to produce (material, labor, overhead, margin), used to test vendor bids and inform negotiation.

Tail spend

The many small, fragmented purchases across numerous vendors, where consolidation savings often live.

Put the vocabulary to work: the free calculators and decision guides apply these terms, and the free Applied AI for Finance and Accounting course teaches them in context.
