2. Executive Summary & Purpose

This SOP defines the standard process for creating, approving, and issuing a purchase order (PO). A purchase order is a commercial document a buyer sends to a supplier to authorize a purchase at agreed prices and terms. It protects both sides: the buyer gets a record of exactly what was ordered and at what price, and the supplier gets a binding commitment to pay. Companies that skip POs end up with invoice disputes, duplicate orders, and spending nobody approved.

3. Scope & Prerequisites

• Scope: All purchases of goods and services above the company's petty-cash threshold. Applies to the requester, the approver, and accounts payable.
• Required Tools & Software:
  • The PO template (Section 8) or the company's procurement system
  • Approved supplier list with current pricing or quotes
  • Budget or cost-center code for the purchase
• Prerequisites:
  • Obtain at least one written quote for the goods or services (two or more quotes above your company's competitive-bid threshold).
  • Confirm the supplier's legal name, billing address, and payment terms.
  • Verify budget availability with the cost-center owner before issuing.

5. Step-by-Step Procedure

Phase 1: Request and Quote

• Identify exactly what is needed: item descriptions, quantities, specifications, and required delivery date.
• Get written quotes from approved suppliers. Record the supplier name, quote date, and quoted price for each.
• Select the supplier based on price, delivery time, and quality, following the company's bid rules.
• Confirm the budget code and available balance with the department manager.

Phase 2: Create the Purchase Order

• Assign the next sequential PO number from the register. Never reuse or skip numbers.
• Fill in the buyer and supplier blocks in Section 8 with full legal names and addresses.
• Enter each line item with description, quantity, unit of measure, unit price, and extended total.
• Add shipping, tax, and any discounts as separate lines, then compute the grand total.
• State the required delivery date, delivery address, and payment terms (e.g., Net 30).

Phase 3: Approve and Issue

• Route the PO to the authorized approver for signature. The requester cannot approve their own PO.
• Send the approved PO to the supplier by email or the procurement portal. Keep a copy.
• Log the PO number, supplier, amount, and date in the PO register or system.

Phase 4: Receive, Match, and Pay

• When goods arrive, receiving checks the shipment against the PO: correct items, correct quantities, no damage.
• Accounts payable matches the supplier invoice against the PO and the receiving record before paying (three-way match).
• File the closed PO with its invoice and receiving documents. Mark the PO number as fulfilled in the register.

6. Quality Assurance & Pro-Tips

Best Practices

• One PO per supplier per order. Combining multiple suppliers on one PO creates matching errors at payment time.
• Describe items precisely. Part numbers, model names, and sizes prevent the supplier from substituting the wrong item.
• Lock prices on the PO. The PO is the buyer's evidence if the invoice comes back higher than quoted.
• Set a PO threshold. Small routine purchases below a set amount can go on a company card; everything above needs a PO.

Common Pitfalls

• Ordering before the PO is issued. A verbal order with no PO means no agreed price and no budget check. The PO comes first.
• Missing delivery address. Suppliers ship to their default address unless the PO states otherwise. Always specify "ship to."
• Skipping the three-way match. Paying invoices without matching them to the PO and receiving record is how duplicate and wrong payments happen.
• Reusing PO numbers. Duplicate numbers corrupt the register and make audits painful. Sequential, gap-free numbering only.

Metric Thresholds

• PO-to-invoice match rate: 100% for all invoices above the PO threshold. No payment without a matching PO.
• Approval turnaround: POs approved within 2 business days of submission.
• Price variance tolerance: Invoice unit prices must match PO unit prices exactly; any variance requires written approver sign-off.

7. Frequently Asked Questions

• Q: What is the difference between a purchase order and an invoice?
  • A: The buyer creates the purchase order to request goods at set terms. The supplier creates the invoice after delivery to request payment. The PO comes first; the invoice references it.
• Q: Is a purchase order legally binding?
  • A: Once the supplier accepts it, a PO functions as a contract for that purchase in most jurisdictions. This template is for informational purposes; consult legal counsel for your jurisdiction.
• Q: Can I change a purchase order after sending it?
  • A: Issue a written PO amendment referencing the original PO number, and get the supplier's acknowledgment. Never edit a sent PO silently.
• Q: Do small businesses need purchase orders?
  • A: Any business that orders from suppliers benefits from POs. Even a one-person company avoids billing disputes with a simple numbered PO per order.
• Q: What payment terms should I put on the PO?
  • A: Use the terms you negotiated with the supplier (common options: Net 15, Net 30, Net 60, or due on receipt). If no terms were negotiated, state "Net 30" and confirm the supplier accepts it before issuing.
