5. Step-by-Step Procedure

Phase 1: Requisition and Vendor Verification

• 1.1 Initiate the purchase requisition within the ERP system, ensuring the currency is explicitly designated (KRW or approved foreign exchange currency).
• 1.2 Validate the SK vendor against the National Tax Service (NTS) database using their unique 10-digit Business Registration Number (사업자등록번호).
• 1.3 Confirm the vendor's Corporate Registration Number (법인등록번호) and verify that the banking details match the registered entity name on file.

Phase 2: PO Drafting and Tax Structuring

• 2.1 Generate the Purchase Order draft utilizing the Template Registry SK-compliant PO template ID TR-SK-PO-2023.
• 2.2 Ensure the inclusion of mandatory statutory fields: Supplier Name, Representative Director name, Business Address, and exact Itemized Description.
• 2.3 Apply the standard 10% Value-Added Tax (VAT / 부가가치세) calculation line item unless explicit zero-rating documentation (e.g., export verification) is attached.
• 2.4 Attach all bilingual (English/Korean) Statements of Work (SOW) or technical specifications to the PO record.

Phase 3: Authorization and Issuance

• 3.1 Route the PO draft through the automated multi-tier workflow based on financial thresholds (Tier 1: < 10M KRW, Tier 2: 10M–50M KRW, Tier 3: > 50M KRW).
• 3.2 Secure digital sign-off from the departmental lead and financial controller using the enterprise digital signature protocol.
• 3.3 Transmit the finalized, system-stamped PO to the vendor via the integrated EDI or secure enterprise portal, retaining the delivery receipt hash.

Phase 4: Intake and e-Tax Invoice Matching

• 4.1 Receive goods or services, logging physical or digital proof of delivery (Inspection Report / 검수조서).
• 4.2 Receive the mandatory electronic Tax Invoice (전자세금계산서) issued directly from the NTS-approved ASP (Application Service Provider) system.
• 4.3 Execute a 3-way match (PO, Receiving Report, and e-Tax Invoice) within the ERP system to verify line items, quantities, and monetary values.

6. Quality Assurance & Verification

Key Metric Thresholds

• PO Cycle Time: Requisition to issuance must not exceed 48 business hours.
• Tax Matching Accuracy: 100% compliance required for NTS e-Tax Invoice validation; zero tolerance for manual tax adjustments without legal sign-off.
• Audit Trail Completeness: 100% of POs must possess an unbroken digital audit trail linking requisition to payment.

Common Pitfalls

• Failing to verify the 10-digit NTS Business Registration Number, leading to undeductible input VAT.
• Utilizing outdated PO templates lacking statutory Korean commercial clauses.
• Processing vendor payments without a matching NTS-verified e-Tax Invoice.

Audit Checklist

• Vendor Business Registration Number verified via NTS portal within 24 hours of PO creation.
• 10% VAT correctly isolated and calculated on the PO line items.
• Digital signatures applied via authorized corporate certificates.
• 3-way match successfully executed prior to payment queue entry.

7. Troubleshooting FAQ

Q1: The vendor's business registration status shows as "Closed" or "Suspended" in the NTS database during Phase 1. What action should be taken?

A: Immediately halt the procurement workflow. Do not issue the PO. Notify the requesting department lead and compliance officer. The vendor must re-register and provide updated, active status verification before the onboarding and PO process can resume.

Q2: How should discrepancies between the PO total and the issued e-Tax Invoice be resolved?

A: Do not process the 3-way match. Route the invoice back to the vendor with a formal Discrepancy Notice. The vendor must issue a revised e-Tax Invoice (수정세금계산서) through the NTS-approved platform reflecting the exact terms of the original authorized PO.
