Usually the same document, seen from opposite sides.
In everyday use, an invoice and a bill both tell a customer what they owe. The seller usually calls the document an invoice; the buyer may call it a bill. The practical difference is convention: invoices are common in business-to-business work with itemisation and payment terms, while bills often imply payment is due immediately.
Plain-English answer · Business and consumer usage · Invoice and receipt differences
The one-line answer — You send an invoice; your customer receives a bill. The wording changes more often than the document does.
The supplier records an invoice in accounts receivable. The customer records the same document as a bill in accounts payable.
Invoice is the standard term for itemised B2B work, sequential numbering and payment terms such as net 14 or net 30.
Bill is common for restaurants, utilities, subscriptions and other situations where the amount is presented for immediate or routine payment.
An invoice may allow a future due date. A bill often sounds immediately payable, but the actual due date and contract terms control when payment is owed.
The label alone does not determine tax treatment. The document still needs the information required for the transaction and jurisdiction, especially where it is a tax invoice.
Invoice and bill request or record money owed. A receipt proves the customer has actually paid. Marking an invoice paid may serve as proof, but a receipt is clearer.
Whether the heading says invoice or bill, confirm what was supplied, the total, tax and when payment is due.
Compare the document with the accepted quote, order or contract. Query unexplained differences before paying.
The supplier tracks an invoice receivable; the customer tracks a bill payable. Use the same document number so both records reconcile.
Once paid, update the invoice or bill status and retain the payment record or receipt.
A consultant completes $1,500 of agreed work and allows 14 days to pay.
Takeaway: Invoice and bill describe the same obligation from opposite accounting perspectives; the invoice number keeps both records aligned.

Accounting systems often separate money coming in from money going out. A sales invoice is money the business expects to receive; a supplier bill is money the business must pay. They can be the same document viewed by different organisations.
Not necessarily. Bill often implies immediate payment, but the stated due date and agreed terms control. Utility bills, for example, are called bills even though they usually have a future due date.
No, not by itself. It shows what was charged or owed. A receipt, bank record or invoice clearly marked paid with payment details is evidence that the money was received.
Use invoice for professional business billing, particularly when the document is numbered, itemised and gives payment terms. Use the legally required heading where applicable — for example, an Australian GST document may need to be clearly identified as a tax invoice.
Common fields are seller and buyer details, a unique invoice number, issue and due dates, itemised goods or services, subtotal, tax, total, payment terms and instructions. Mandatory requirements vary by country and whether the document is a tax invoice.
