Why a clear invoice is part of your financial record
An invoice is the bill you send after you deliver work or goods. It states who must pay, how much, and by when. GOV.UK invoice requirements lists what many UK VAT invoices must include, such as a unique number, dates, supplier and customer details, and a description of the supply.
In the United States, the IRS recordkeeping rules for small businesses explain that you must keep records that support income and expenses. A numbered invoice with dates and amounts is one of the simplest records you can keep. This generator creates a PDF you can send and file.
What to put on every professional invoice
- Your details: legal name, address, email, and logo so the client knows who to pay.
- Client details: who owes the money and how to reach them.
- Number and dates: a unique invoice number, issue date, and due date.
- Line items: what was supplied, quantity, rate, and amount.
- Totals: subtotal, tax, discounts, and the amount due.
- Notes: payment terms, bank details, or a short thank-you.
If you charge VAT in the UK, follow GOV.UK invoice requirements. If you report business income in the U.S., keep the PDF with the IRS recordkeeping rules for small businesses in mind. Totals on this page update as you type so the math stays consistent.
