4. Step-by-Step Procedure

Phase 1: Requisition and Supplier Verification

• 1.1 Identify operational requirement and verify budget availability within the departmental cost center inside the ERP system.
• 1.2 Confirm prospective vendor is registered with the Accounting and Corporate Regulatory Authority (ACRA) of Singapore and holds a valid Unique Entity Number (UEN).
• 1.3 Verify vendor tax status (GST-registered vs. non-GST-registered) via the IRAS GST registered business search portal.
• 1.4 Secure a minimum of three (3) competitive quotations for expenditures exceeding SGD 10,000, in accordance with Template Registry procurement thresholds.

Phase 2: PO Drafting and Tax Structuring

• 2.1 Access the Template Registry Singapore PO template or procurement module.
• 2.2 Populate the header with Template Registry's legal entity name, registered business address, and Singapore UEN/GST registration number.
• 2.3 Input vendor details precisely as listed on ACRA bizfile, including official trading name, registered address, UEN, and GST registration number (if applicable).
• 2.4 Assign a unique, sequentially generated PO Number adhering to the format: TR-SG-YYYYMMDD-[XXXX].
• 2.5 Itemize line items with precise descriptions, SKU codes, unit quantities, and agreed unit prices denominated strictly in Singapore Dollars (SGD), unless foreign currency hedging has been pre-approved by Treasury.
• 2.6 Calculate subtotal, apply applicable Singapore GST (9%) exclusively to taxable supplies, and state the final gross total clearly.
• 2.7 Attach mandatory commercial terms, including Incoterms 2020 (if importing physical goods) and standard payment terms (default: Net 30 Days from invoice receipt).

Phase 3: Authorization and Issuance

• 3.1 Route drafted PO through the automated workflow engine for sign-off based on the Delegation of Authority (DoA):
  • Up to SGD 5,000: Department Manager
  • SGD 5,001 to SGD 50,000: Head of Procurement & Finance Director
  • Above SGD 50,000: Managing Director / Executive Board
• 3.2 Ensure electronic signatures/timestamps are cryptographically locked upon final executive approval.
• 3.3 Transmit the authorized PO to the vendor via secure corporate email or the InvoiceNow (Peppol) network.
• 3.4 Archive the digital read-only PDF copy in the secure Document Management System (DMS).

5. Quality Assurance & Verification

5.1 Key Metric Thresholds

• Cycle Time: PO generation to vendor dispatch must not exceed 24 business hours for standard requisitions.
• GST Accuracy Rate: 100% compliance on tax code application (standard-rated, zero-rated, or exempt supplies).
• DoA Compliance: Zero unauthorized commitments.

5.2 Common Pitfalls

• Incorrect UEN Format: Failing to include the correct 9-character or 10-character alphanumeric UEN format required by Singapore authorities.
• Implicit GST Inclusion: Quoting gross prices without breaking down the 9% GST component, leading to tax reconciliation failures during Goods and Services Tax returns (F5 filings).
• Currency Mismatch: Issuing POs in foreign currency without linking the exchange rate to the Monetary Authority of Singapore (MAS) daily exchange rate index.

5.3 Audit Checklist

• Does the PO contain Template Registry’s corporate UEN and GST registration number?
• Is the vendor's UEN verified against ACRA records?
• Are taxable and non-taxable line items clearly separated for GST calculation?
• Does the approval trail match the financial Delegation of Authority matrix?
• Is the digital audit trail preserved for the statutory 5-year retention period mandated by Singapore law?

6. Troubleshooting FAQ

Q1: The vendor is an overseas entity not registered for Singapore GST. How should the tax line be handled on the PO?

• Solution: For overseas vendors supplying services or digital goods consumed in Singapore, apply the Reverse Charge (RC) mechanism if Template Registry meets the annual registration thresholds, or mark the line as "Out-of-Scope" for GST. Ensure shipping terms (Incoterms) and import permits (Declared Value via CrimsonLogic / TradeNet) are cross-referenced if importing physical goods. Do not calculate local 9% GST on non-registered foreign invoices unless importing physical freight, where GST is handled separately by Singapore Customs at the point of entry.

Q2: A purchase order must be amended after it has been fully approved and dispatched to the vendor. What is the protocol?

• Solution: Do not alter an issued PO in-system. Issue an official "Purchase Order Amendment" referencing the original PO number with a clear version increment (e.g., TR-SG-20231024-0012-V2). Re-route the amendment through the corresponding DoA approval workflow if the monetary value increases by more than 10% or alters core scope, then dispatch the revised document to the vendor alongside a formal cancellation notice for the prior version.
