• Perform initial completeness reviews and validate business purpose, scope, dates, currency, amount, budget owner, payment method, accounting fields, vendor information, approvals, and supporting documentation.
• Follow up with requesters, vendors, and internal stakeholders to resolve missing information, prevent workflow delays, and expedite blockers promptly.
• Coordinate requests through the appropriate Procurement, FP&A, functional, Legal, Security, People, IT, vendor, and signature review steps while tracking normal and urgent requests against established service targets.
• Coordinate contractor and vendor onboarding, including statements of work, agreements, tax documentation, vendor records, banking information, portal completion, and required approvals.
• Partner with People Operations and IT on contractor classification, background-check requirements, equipment, email, application access, and onboarding tickets.
• Determine whether an NDA or mutual NDA is required and route the appropriate document for signature.
• Prepare approved contracts and supporting documents for signature; monitor DocuSign status, coordinate vendor countersignature, and ensure fully executed agreements are properly stored.
• Maintain accurate procurement records, including Zip request numbers, purchase order numbers, agreement numbers, vendor names, renewal dates, links, and other key identifiers.
• Support change orders and foreign-currency requests by confirming revised scope, amount, dates, payment terms, approval requirements, native currency, USD equivalent, FX-rate basis, and total purchase value.
• Support purchase order issuance and changes, invoice questions, vendor follow-up, and invoice reconciliation in coordination with Finance and Accounts Payable.
• Maintain visibility into aging requests, open vendor actions, outstanding signatures, pending invoices, renewal dates, and requests ready for closeout.
• Conduct monthly reviews of open purchase orders and requests, recommending items for closure, extension, or escalation and ensuring final documentation is complete.
• Develop and maintain process maps, queue trackers, handoff documentation, backlog-cleanup plans, and organized records of key deadlines, high-risk or high-value items, signature authorities, open vendor issues, and internal contacts.
• Prepare and distribute weekly queue and service-level dashboards to Procurement and Finance stakeholders, highlighting progress, risks, blockers, and recommended actions while ensuring timely progression of assigned requests.
