Invoice Template

• Business name and logo go top-left
• Invoice number and dates go top-right
• Never reuse an invoice number
• Net 30 for companies, 7-14 days for freelancers

Your business name and address go top-left with your logo; the word Invoice, the number and the dates go top-right. Number invoices sequentially and never reuse one: auditors and accounting software both rely on gaps being meaningful. A due date is not optional. Net 30 is common for companies, 7 to 14 days for freelancers, and payment on receipt for one-off jobs.

• Describe what, how many, and at what rate
• Group hours by task, not by day
• Let the tool calculate amounts

Describe each deliverable in a way the client's accountant will recognise without asking you: what it was, how many, at what rate. Group hours by task rather than by day. Round rates to the cent and let the tool compute amounts so the arithmetic is never questioned.

• Show subtotal before any adjustment
• Discount first, then tax on the discounted amount
• List any deposit already paid
• Bold the balance due

Show the subtotal before any adjustment, then the discount, then tax on the discounted amount, then the total. If part of the total was already paid, a deposit for example, list it and show the balance due in bold. The balance due is the only number most clients look at.

In the generator's Korean business form, with tax excluded from unit prices (부가세 별도) at a 10% rate, a three-item sample totals 공급가액(supply amount) 1,960,000, 세액(tax) 196,000, and 합계(total) 2,156,000원, written out as 일금 이백십오만육천 원정 in the Korean-numeral line the form adds automatically.

• Bank details or payment link go in Notes
• Due period, methods and late fee in terms
• A short thank-you line is fine
• Keep the invoice to one page

Put bank details or a payment link in Notes, and the terms in Payment terms: the due period, accepted methods, and any late fee. A short thank-you line is fine; a paragraph is not. Keep the whole invoice to one page whenever possible: a three-item Korean-form sample renders as one page, but adding enough items pushes it to a second page, where the item table's header row (품목·규격·수량·단가·공급가액·세액) repeats at the top so the columns still make sense without flipping back.

• Sample PDF: one page, about 301 KB
• Korean font is embedded, not a fallback
• No Hangul rendered as empty boxes
• Font failure falls back to print-to-PDF

Downloading the three-item Korean-form sample produced a one-page PDF of about 301 KB with the NanumGothic font embedded in the file. The rendered page carried the title, the buyer's block, the supplier's box, a 합계 금액 (total amount) line, the item table with 공급가액 and 세액 columns, the totals, and the notes and payment terms; nowhere did Hangul render as empty boxes.

If the Korean font can't be loaded, the tool opens the browser's print dialog instead of a PDF so you can choose Save as PDF there; this failure path was not re-tested in this check. A Latin-only standard-layout PDF's file size was not measured here.
