What is the correct invoice format?

There is no single official layout. What matters is that the required details are there and easy to find: who is billing whom, a unique number, the date, what was supplied, any tax and the total due. The tax offices we checked list required details, not designs.

Is a bill format different from an invoice format?

In everyday use, bill and invoice mean the same thing for a business sale, and the layout is the same. If the law in your country names a particular document, such as a tax invoice, follow that wording and include the details it lists.

Does an invoice have to be in English?

Not always. In the UK, HMRC allows invoices in another language, but you must provide an English translation within 30 days if it asks. Other countries set their own rules, so check your tax office's guidance before billing in another language.

What date format should I use?

Use the format your customer expects, or avoid the question by writing the month in words, such as 27 October 2026. Number only dates are read differently in different countries, and a misread due date can turn into a late payment and an awkward phone call.

Can I use the same format for every country?

Mostly. The blocks, the order and the line table can stay the same. What changes is the tax part: the tax name, your registration number, the rate, and in Australia, Singapore, South Africa and the UAE, the title wording. A country preset in the editor handles those for you.

Invoice Format: Every Part Explained, With Country Rules

Invoice format, part by part

The standard invoice format has a header that names the document and gives its number and dates, two blocks for the seller and the buyer, a table of what was supplied, a totals block with any tax, and a footer for payment. This page explains each part, then how the format shifts by country and for services or goods.

The standard invoice format, top to bottom

Read an invoice from the top and it answers questions in the order a customer asks them: what is this, who sent it, what is it for, how much, and how do I pay? The table lists each block, what belongs in it, and why it is there.

Part	What goes in it	Why it matters
Header	Title, invoice number, issue date, due date	Identifies the document and starts the payment clock
Seller block	Your name, address, email, phone and tax number	Shows who is owed the money
Buyer block	Customer name, billing address, their tax number if needed	Shows who owes it
Line items	Description, quantity, unit price, line amount, tax rate	Lets the customer check the charge
Totals	Subtotal, discount, tax, shipping or fee, amount due	The figure to pay, with the working shown
Payment	Bank details or other methods, terms, late fee policy	Removes any excuse to pay late

How the format changes by country

The skeleton above works everywhere, but tax rules add fields in some countries and set the title in a few. The table shows the main difference in each of the ten countries we cover, from official tax office pages checked in October 2026.

Country	Tax and number	Title wording	Detail to know
Australia	GST, ABN	Tax invoice, if registered	Buyer’s identity or ABN over $1,000
New Zealand	GST, GST number	Optional since 2023	Minimal details at $200 or less
United Kingdom	VAT, VAT number	None set	Total VAT shown in sterling
Ireland	VAT, VAT number	None set	Breakdown by VAT rate
United States	State sales tax	No federal rule	Rates set by states and localities
Canada	GST/HST, business number with RT	Not required	More details from $100 and $500
India	CGST, SGST or IGST; GSTIN	Not in the CBIC rule summary	HSN or SAC code, place of supply
Singapore	GST, GST registration number	Tax Invoice, prominent	Simplified version up to $1,000
South Africa	VAT, VAT number	Tax Invoice, VAT Invoice or Invoice	Abridged version under R5 000
UAE	VAT, TRN	Tax invoice, clearly displayed	VAT shown in dirham

Format for services and for goods

The blocks stay the same, but the line items change shape. A services bill describes work and time; a goods bill describes items and where they went. Mixing both on one invoice is fine if each line is clear.

Services: describe the work and the period it covers, then hours times a rate or a fixed fee, as in “Bookkeeping, September 2026, 6 hours at $55”.
Goods: give the item name or code, the quantity, the unit price and the delivery address if it differs from the billing address. HMRC asks for the unit price on countable goods.
India: goods lines carry an HSN code and services lines an SAC code. CBIC asks for goods invoices in triplicate and services invoices in duplicate.

Three sample layouts, described

The same information can sit on the page in different ways. Here are three layouts that suit different kinds of business, each available as a design in the editor. Choose by how many lines you bill, not by looks alone.

Short service bill: seller details on the left, number and dates on the right, a few lines and a large amount due, as in the Minimal design.
Parts and labor bill: a ruled grid for a long list of parts, as in the Ledger design.
Formal professional bill: a centered header and generous spacing for consultants and studios, as in the Centered design.

Dates, language and currency

Small choices in format cause real confusion across borders. Dates are the classic case: 03/04/2026 is 3 April in Australia and March 4 in the United States. Writing the month as a word, such as 27 October 2026, avoids the problem in every country.

Currency has firmer rules in some places. Ireland asks for foreign currency figures to be shown in euro too, and the UAE wants VAT shown in dirham.
