Invoice vs bill: what's the difference?
Mostly they are the same document: the seller sends an invoice, and the buyer who receives it records it as a bill to pay. In everyday speech a bill is also any request to pay, on the spot or by a set date, like a restaurant bill or a phone bill.
How the words are used in the US and UK, and where each one goes in your books.
The short answer: one document, two sides
Is a bill an invoice? In business, mostly yes: an invoice and a bill are usually the same document, and the word you use depends on which side of the sale you're on. When you've done the work or delivered the goods, you send your customer an invoice, a document that says what you supplied, what it costs, and when and how to pay. Your customer receives that same document and, in their accounting software and in most American business talk, records it as a bill: an amount they owe and have to pay by the due date. So "invoice" is the seller's word and "bill" is the buyer's word for one and the same request for payment.
Accounting software makes this easy to see, because it keeps invoices in one place and bills in another. Invoices are money coming in to you and bills are money going out from you, which means every invoice you send turns up as a bill in somebody else's books. For example, a freelance designer who charges a bakery $1,200 for a new menu and logo has issued an invoice, while the bakery's bookkeeper has received a bill for $1,200. Nothing about the PDF changed on its way from one inbox to the other; only the point of view did.
The rest of the difference between an invoice and a bill comes from two other things: "bill" also has a looser everyday meaning, and British and American English use the word a little differently. The sections below explain both, and then how invoices and bills show up in the books. A bill of exchange, a bill of sale and a bill before Congress or Parliament are different things altogether and aren't covered here.
A bill in everyday life, and what makes an invoice
What is a bill outside the office? In everyday speech it's any request to pay for something you've already had: the bill at the end of a meal, the phone bill, the electricity bill, or the bill the plumber hands you after fixing a leak. Many of these are paid on the spot or by a fixed date, and nobody expects much paperwork. A restaurant bill is often just a list of what you ordered and a total, with no name on it and no number you would ever quote when paying.
An invoice is the formal kind of bill that businesses use, above all with other businesses, and it's made to be checked, paid and filed. That's why it carries details a casual bill often leaves out: a unique invoice number, the invoice date, your name and address and your customer's, a description of each item with its quantity and price, any tax you charge, the total due and the payment terms. Those details let your customer match the invoice to what they ordered, pay the right amount to the right account, and keep a record for their own taxes. The guide to what an invoice is and what it contains goes through each one.
How strict the rules are depends on the country. In the UK, the numbering is set out plainly. Every invoice needs a unique identification number, and a VAT invoice needs a sequential number, from one or more series, that uniquely identifies it. A VAT invoice is the one a business registered for VAT (value added tax, the UK's tax on most sales) issues, and it shows the VAT charged and the seller's VAT registration number.
The US is more relaxed. No federal law prescribes invoice numbering; giving each invoice a unique number is customary, and invoices to federal agencies must carry an invoice number, account number or other identifying number agreed in the contract. In practice both countries come to the same thing for you: give every invoice its own number and never use one twice. The full lists of what to include are on the UK invoice and US contractor invoice pages.
How the words are used in the US and the UK
Part of the bill vs invoice question is simply a matter of which English you speak. In the US, "bill" is both the household word and the bookkeeping word: Americans pay the electric bill and the doctor's bill, and in a company "bills" usually means invoices received from suppliers that are waiting to be paid. The team that sends invoices out is often called billing, and to "bill a client" just means to send them an invoice. One trap for visitors is that Americans ask for the check rather than the bill at a restaurant, and a check is also the paper payment many US invoices still accept, so "pay by check" on an invoice has nothing to do with dinner.
In British English, "the bill" is what you ask for at the end of a meal, and gas and phone bills are bills too, but in business the usual word is invoice in both directions. British bookkeepers talk about sales invoices (the ones you send) and purchase invoices (the ones you receive), kept in the sales ledger and the purchase ledger, and they call customers who owe money debtors and suppliers who are owed money creditors. Accounting software sold in the UK often labels purchase invoices "bills" all the same, so a British user may see both words for the same thing. "Billing" and "to bill someone" mean the same on both sides of the Atlantic, although the British spell the paper payment "cheque".
What this means for you is simple. Wherever you are, the document you send to get paid should say "Invoice" at the top, because that's the word your customer's bookkeeper looks for before entering it as a bill, and it's the word the rules in both countries use. "Bill" is fine in conversation, in an email ("I'll bill you at the end of the month") and on the buyer's side of the books.
Invoices and bills in your books
In bookkeeping, the two sides of the same document land in two different places. For the seller, a sent invoice is a sale and an amount the customer owes, recorded under accounts receivable, which is the money owed to you. For the buyer, the invoice received is a bill, recorded under accounts payable, which is the money you owe. When the customer pays, both sides close the item: the seller's receivables go down by the amount received, and the buyer's payables go down by the same amount.
Take the designer again. Their invoice INV-0042 for $1,200, due in 30 days, sits in their receivables as money the bakery owes. In the bakery's software it's a bill from the designer for $1,200 with the same due date, and when the bakery pays and quotes INV-0042 with the payment, the designer can match the money to the invoice straight away. That's why the invoice number and due date matter to both sides: without a due date a bill can sit unpaid because nobody knows when it's due, and without a number a payment can arrive that nobody can match.
Invoices you send and bills you receive are both business records, so keep them; the usual period is 3 years in the US and 6 years in the UK. The table below puts the three meanings of the words side by side.
| Invoice | Bill (in business) | Everyday bill | |
|---|---|---|---|
| Who calls it that | The seller who sends it | The buyer who receives the same invoice | Anyone asked to pay for something they've had |
| What it asks for | Payment for goods or services, by the due date | Payment to the supplier, by the due date | Payment on the spot or by a set date |
| What it usually shows | Number, date, both parties, items, tax, total, payment terms | Whatever the supplier's invoice shows | Often just the items and a total |
| Where it goes in the books | Accounts receivable (sales ledger) | Accounts payable (purchase ledger) | Accounts payable, if a business pays it |
| Example | Your invoice to a client for a new logo | That client's entry for your invoice | A restaurant check, a phone bill |
The invoice maker covers the sending side of this. Its overview lists your invoices with their status (draft, sent or paid), an Overdue filter picks out the ones past their due date, and a CSV export gives your accountant the whole list. It doesn't record the bills you receive from your own suppliers, which belong in your bookkeeping software or with your accountant.
Making an invoice when you're the one sending it
If you're the one getting paid, what you need is an invoice, and the maker on this page makes one in your browser: you fill it in and download it as a PDF or print it, without an account. A first invoice takes these steps.
- Enter your business details once: your name and address, your VAT registration number if you're registered for VAT in the UK, the bank details you want to be paid into (for a US bank, the routing and account number), and a logo if you have one.
- Add your client's name and address. Clients are saved, so you can reuse them on the next invoice.
- Add each item with its quantity, unit (hours, days, pieces) and price. If you're VAT registered in the UK, the standard rate of 20% is preset once your business country is set, and if you aren't registered you charge no VAT at all; in the US you add sales tax at your rate only on the lines that are taxed.
- Check the invoice number, which counts up automatically, set the invoice date and the due date, and write your payment terms in the notes.
- Download the PDF and send it yourself, then mark the invoice as sent; or, with a free account, send it from the maker by email or as a link, up to 10 invoices a month. When the money arrives, mark it as paid.
Two more documents sit either side of the invoice. If a client wants to know the price before you start, send a quote, which is an offer rather than a request for payment; when they accept, "Create invoice from this" turns it into an invoice with the same client, lines and prices and the next invoice number. The guide to the difference between a quote and an invoice explains when to use each. After the client has paid, some want a receipt as proof, and "Create receipt" on the invoice makes one with the same lines and amounts and marks the invoice as paid; invoice vs receipt covers when you need one.

Can I put 'Bill' at the top instead of 'Invoice'?
For a small job for a private customer, nobody is likely to object, and plenty of tradespeople hand over a 'bill'. For business customers, use 'Invoice': it's the document their bookkeeper is waiting for, and the rules in both countries are written about invoices. In the UK a VAT-registered business issues a VAT invoice with its own list of required details, which the UK invoice page sets out.
Is a bill the same as a receipt?
No. A bill or invoice asks for payment, while a receipt confirms that payment has been received. At a restaurant the two arrive minutes apart, which blurs the line, but in business they are separate documents with different jobs. The guide to invoice vs receipt explains when you need each.
What is a billing address?
It's the address the bill or invoice is made out to, which on an invoice is your customer's name and address. It can differ from the shipping or delivery address where goods actually go. When you pay by card, the billing address is the one your card issuer has on file for you.
Is a statement of account the same as a bill?
Not quite. A statement lists the invoices you've sent a customer over a period and the payments received, so they can see in one place what is still owed. It isn't a new invoice, and the customer shouldn't enter it as another bill, or the same amount would be counted twice.
