Also known as: GPO

A group purchasing organisation is an entity that pools the purchasing volume of many members to negotiate better prices and terms with suppliers.

A group purchasing organisation (GPO) aggregates the demand of independent buyers — hospitals, businesses or institutions — and negotiates contracts on their behalf. By combining volume, members access pricing and terms they could not secure alone, while the GPO handles supplier negotiation and contract management. Members typically retain the choice of whether to buy under each contract.

GPOs are well established in sectors like healthcare and hospitality where many small buyers purchase similar goods. The benefit is lower prices and reduced sourcing effort; the trade-off can be less tailored terms and reliance on the GPO's chosen suppliers. Marketplaces achieve a similar aggregation effect by concentrating demand and supplier competition in one place.

Key points

  • GPOs pool many members' volume to negotiate stronger pricing and terms.
  • Members usually keep discretion over whether to buy under each contract.
  • The trade-off is less tailored terms and reliance on the GPO's supplier panel.
