Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
Use a purchase order when you need to confirm goods, services, quantities, prices, delivery terms, and internal approval before the supplier bills you. The PO should identify the buyer, supplier, PO number, issue date, requested delivery date, item descriptions, quantities, unit prices, currency, tax treatment, and payment terms. For South Korea, use KRW unless the contract states another settlement currency.
A PO is a commercial control document. It is not the South Korean VAT tax invoice. South Korea uses VAT, and compliant tax invoices under the Value-Added Tax Act identify VAT rather than GST or sales tax. The PO should collect the details the supplier will later need, especially names, business registration numbers, supply value, and the expected VAT amount.
South Korean VAT tax invoices use business registration numbers as the core tax identifiers. A compliant VAT tax invoice must state the supplier's registration number and name or trade name, plus the registration number of the person receiving the supply. Add those identifiers to the PO when available so accounts payable can match the PO, delivery record, and tax invoice without chasing missing data.
The standard South Korean VAT rate is 10 percent of the taxable supply value unless a zero-rate or exemption rule applies. A VAT tax invoice must separately state the value of supply and the VAT amount. Your PO can show an estimated VAT line, but the supplier's final tax invoice controls the official VAT record for input-tax credit support.
The most common PO problem is a mismatch between the purchasing instruction and the later supplier document. A product name that differs from the quote, a missing service period, or a price shown tax-inclusive in one place and tax-exclusive in another creates approval delays. Use one line per item or service and keep discounts, freight, and tax treatment visible instead of hiding them in notes.
South Korean tax invoices are generally issued at the time of supply, with statutory exceptions such as consolidated monthly issuance by the 10th day of the following month where the VAT Act permits it. Corporate businesses and prescribed individual businesses must issue electronic tax invoices, and issuance details generally go to the National Tax Service by the day after issuance under decree rules.
A free PO template is enough for a one-off supplier order, a small purchase, or a simple services engagement with fixed scope. It gives you a clean document to approve internally and send to the supplier. Keep the signed PO, quote, delivery evidence, and final VAT tax invoice together so the accounting record stays complete.
A managed workflow fits recurring projects, variable billable work, or teams that price labor differently by person, project, or task. Everhour separates cost and billable rates, supports per-person defaults and per-project overrides, preserves dated rate history, and can price billable work by project, member, or task before billing documents are prepared.

A South Korea purchase order is not a VAT tax invoice. The PO records the buyer's order and approval before or during fulfillment. The VAT tax invoice is the statutory tax document under the Value-Added Tax Act and must include required registration, supply value, VAT amount, and preparation-date details.
The business registration number is the tax-registration identifier used on Korean VAT tax invoices. The supplier's registration number and name or trade name must appear on the VAT tax invoice, and the buyer's registration number is also required for the person receiving the supply.
A Korean PO should show VAT treatment clearly when the price is taxable, especially when the supplier expects the buyer to approve a tax-exclusive supply value plus VAT. South Korea's standard VAT rate is 10 percent of the taxable supply value unless a zero-rate or exemption rule applies.
Payment terms can be set by the PO, contract, or supplier agreement. South Korean VAT invoice-content rules do not set a universal net-payment period. Ordinary payment due dates are contractual, while commercial overdue claims may be affected by the Commercial Act default-interest framework.
A missing business registration number causes avoidable matching work because the VAT tax invoice must identify the supplier and buyer registration details. Price-format mismatches also create delays, especially when the PO shows tax-inclusive totals but the tax invoice separates supply value and VAT amount.
Everhour separates internal cost rates from client-facing billable rates, with per-person defaults and per-project overrides. Teams can preserve dated rate history and price billable work by project, member, or task, so approved work uses the correct rate when billing documents are prepared.
Use the template for one supplier order. For recurring project work, Everhour keeps dated rates, project pricing, and billable work aligned before invoices are prepared.
