Spot Buy
Also known as: Spot purchase
A spot buy is a one-off, ad-hoc purchase made to meet an immediate need, usually outside of any standing contract or catalogue.
Spot buys happen when a requirement is urgent, infrequent or not covered by an existing agreement — a replacement part, a last-minute event supply, or a niche item. Because they are made quickly and individually, spot buys often carry higher prices and weaker terms than contracted purchases.
Uncontrolled spot buying is a major source of tail spend and maverick spend. Channelling spot purchases through a marketplace or catalogue restores price transparency and approval control, so even one-off buys stay visible, compliant and competitively priced.
