Approve.com

Approve.com is a cloud-based procurement platform founded in 2019 in Israel that lets businesses stand up a proper purchase-order process quickly, streamlining purchase requisitions, multi-step approvals, real-time budgets, and vendor onboarding with real-time spend controls and insights.
