Vendor Relations Coordinator - Costa Rica

Position Overview

The Vendor Relations Coordinatorkeeps Cornerstone's marketing engine moving by owning the path every marketing vendor agreement takes, from first redline to final payment.

• Own vendor onboarding, including supplier setup, tax and banking documentation, and security or data privacy reviews where required.
• Create and track purchase requisitions and POs, and partner with Accounts Payable to match invoices to POs, resolve discrepancies, and ensure vendors are paid accurately and on time.
• Maintain a central contract repository and tracker covering key dates, renewal and termination notice windows, spend, and owners, and proactively alert stakeholders before deadlines.
• Project manage a high volume of concurrent contracts and requests, setting clear timelines, communicating status, and escalating blockers early.
• Act as a friendly, knowledgeable guide for marketers, helping them understand what's needed, how long it takes, and how to plan ahead.
