4. Step-by-Step Procedure

Phase 1: Requisition and Scope Formulation

  • 1.1 Draft the Consulting Statement of Work (SOW) utilizing Template Registry Form SOW-C01, defining explicit deliverables, milestones, timeframes, and acceptance criteria.
  • 1.2 Verify that the proposed consulting engagement aligns with departmental OpEx/CapEx budget allocations within the current fiscal year.
  • 1.3 Confirm vendor status in the Vendor Master Database; if the consultant is a new entity, initiate onboarding via the Vendor Portal to secure tax and banking validation.

Phase 2: PO Generation and Line-Item Coding

  • 2.1 Access the Enterprise Procurement System and initiate a new Purchase Requisition, selecting "Professional Services - Consulting" as the procurement category.
  • 2.2 Input the vendor identification number, effective service start date, and termination date.
  • 2.3 Populate line items reflecting distinct milestones or hourly allocations (avoiding vague, open-ended line items). Ensure accurate General Ledger (GL) coding mapped to the correct cost center.
  • 2.4 Attach the executed SOW, approved budget variance form (if applicable), and compliance certificates directly to the requisition header.

Phase 3: Authorization and Workflow Routing

  • 3.1 Submit the requisition into the automated routing workflow based on financial thresholds:
    • Tier 1 ($2,500 - $24,999): Department Head Approval
    • Tier 2 ($25,000 - $99,999): Director of Procurement & Finance Controller Approval
    • Tier 3 ($100,000+): Chief Operations Architect & Chief Financial Officer Approval
  • 3.2 Audit the compliance flags triggered by the system regarding data handling, indemnification limits, and IP assignment clauses.

Phase 4: Dispatch and Vendor Acceptance

  • 4.1 Upon final systemic approval, convert the requisition to a legally binding Purchase Order containing standard Template Registry procurement terms and conditions.
  • 4.2 Dispatch the PO electronically via the procurement portal to the consultant's designated point of contact.
  • 4.3 Require formal electronic acknowledgment and countersignature of the PO within 3 business days of issuance.

Phase 5: Service Verification and Intake

  • 5.1 Monitor milestone delivery and ensure the consultant logs operational hours or artifact delivery via the project tracking interface.
  • 5.2 Execute formal sign-off on deliverables utilizing Template Registry Acceptance Form AC-02 prior to invoice submission.

5. Quality Assurance & Verification

5.1 Key Metric Thresholds

  • PO Cycle Time: Requisition to PO dispatch must not exceed 48 business hours.
  • PO Compliance Rate: 100% of consulting engagements must have a valid PO issued prior to the commencement of billable work (Zero Retroactive POs).
  • Match Accuracy: Three-way matching (PO, SOW Milestone Acceptance, and Invoice) must achieve a 98% first-pass accuracy rate.

5.2 Common Operational Pitfalls

  • Retroactive PO Generation: Issuing a PO after consulting work has commenced, violating internal controls and creating unapproved financial liability.
  • Vague Deliverables: Utilizing generic descriptions (e.g., "Consulting Services - Q3") instead of measurable, time-bound milestones.
  • Unverified Tax Classification: Engaging international consultants without a verified W-8BEN-E, leading to statutory withholding non-compliance.

5.3 Audit Checklist

  • SOW attached matches exact PO line-item totals.
  • Delegated authority limits respected based on financial matrix.
  • Vendor insurance certificates (if on-site) verified by Risk Management.

6. Troubleshooting FAQ

Q1: What action is required if a consultant begins work before the PO is officially dispatched?

A: Immediate Work Stoppage must be enforced by the Requesting Manager. The procurement system will flag the transaction as an "Unauthorized Commitment." The Requesting Manager must submit an Incident Exception Report detailing the operational justification, which requires sign-off from the Chief Financial Officer before the retroactive PO can be processed and evaluated for disciplinary review.

Q2: How should an overrun in consulting hours or project scope be handled operationally?

A: Do not permit the consultant to continue working beyond the authorized PO threshold. The Requesting Manager must issue a formal PO Amendment Requisition in the procurement system, attaching a revised SOW outlining the justification for the additional scope and capital allocation. The amendment must follow the exact routing and approval matrix defined in Phase 3 before additional services are rendered.

Q3: What is the procedure if the vendor's invoice does not match the milestone amounts specified on the PO?

A: Accounts Payable will place a systemic hold on the invoice (3-Way Match Exception). The Requesting Manager must reconcile the discrepancy with the vendor. If the invoice reflects incomplete milestones, the vendor must reissue the invoice. If the variance is due to an approved change in scope, a PO amendment must be fully executed to align the PO value with the revised billing amount before the hold can be released.
