Supply is an economic word to describe the calculation of theory. It also is used by corporate process of gathering items for establishing the final products, or strengthening inventory of corporation when it comes to commerce.
Procurement is a military language which is often used for handling military equipment.
Supply chain is a gathering of company and inventory as a whole to address/make the final product.
I never use the language on logistics for my intention of clarifying the word choice.
