An invoice app for South Korea should help you prepare a VAT tax invoice for taxable goods or services, not a GST invoice or United States sales-tax invoice. South Korea uses value-added tax, and the standard VAT rate is 10% of the taxable supply value unless a zero-rate or exemption rule applies.
The practical job is simple: create a document the buyer can review, approve, and use for tax records. A South Korean VAT tax invoice must show the supplier's registration number and name or trade name, plus the buyer's business registration number. It must also show the supply value, VAT amount, and date of preparation.
The business registration number is the core tax identifier on Korean VAT tax invoices. Treat it as a required party field, not an optional note. Item details, supply date, supply value, VAT amount, and preparation date all support the buyer's input-tax credit record and reduce back-and-forth after delivery.
A clean service invoice might list consulting services supplied in June, a supply value of ₩1,000,000, and VAT of ₩100,000 as a separate line or tax summary. The total amount due is commercial billing information, while the supply value and VAT amount are the tax invoice amounts that need to stay distinct.
South Korean VAT tax invoices are generally issued at the time of supply. The VAT Act allows statutory exceptions, including consolidated monthly issuance by the 10th day of the following month in permitted cases. An invoice app should make the supply date and preparation date easy to verify before the document goes out.
Electronic tax invoice rules matter for many Korean businesses. Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices rather than paper tax invoices. After issuance, electronic tax invoice details must be transmitted to the National Tax Service by the statutory deadline, generally the day after issuance under the decree rules.
A free invoice app is enough when you need a single Korean VAT invoice, already know the buyer's registration number, and can confirm the VAT treatment, supply date, and payment term from the contract. It also works for a small batch of repeatable invoices when the underlying time, expenses, and approvals already exist elsewhere.
A managed workflow becomes necessary when billable time, project costs, approvals, and invoice status need one source of record. Everhour Reporting gives teams customizable reports with 45+ columns, filters, grouping, exports, scheduled email delivery, and profitability dashboards, so billable work can be reviewed before finance prepares or reconciles invoices.

Yes. South Korea uses VAT for taxable supplies, so a Korean tax invoice needs VAT fields rather than GST or United States sales-tax fields. The invoice should separately show the supply value and VAT amount, with the standard VAT rate at 10% unless a zero-rate or exemption rule applies.
The business registration number belongs on a Korean VAT tax invoice. The supplier's registration number and name or trade name must appear, and the buyer's business registration number must also be recorded for the person receiving the supply.
A South Korean VAT tax invoice is generally issued at the time of supply. The VAT Act permits exceptions, including consolidated monthly issuance by the 10th day of the following month in allowed cases. Use the supply date and preparation date carefully, because they are separate invoice facts.
Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices instead of paper tax invoices. After an electronic tax invoice is issued, the issuance details must be sent to the National Tax Service by the statutory deadline, generally the day after issuance under decree rules.
The app can store a payment term, but South Korean VAT invoice-content rules do not create one universal net-payment period. Ordinary due dates come from the contract. Commercial overdue claims may be affected by the Commercial Act default-interest framework, so the invoice should mirror the agreed term.
Everhour Reporting lets teams review billable time, costs, clients, projects, invoice status, and profitability with customizable reports that include 45+ columns. Teams can group, filter, export, or schedule those reports before Korean VAT invoice amounts move into the billing process.
Everhour Billing & Invoicing can generate invoices from uninvoiced time and expenses, then mark included time as invoiced. That workflow protects previously billed work from accidental reuse while keeping invoice status, number, issue date, and amount visible in Everhour.
Use Everhour Reporting to review billable time, costs, and invoice status before billing. Export or schedule reports so recurring South Korea invoice work stays easier to audit.
