What is an invoice?
An invoice is a document a business sends to a customer requesting payment for goods or services provided. It lists what was delivered, how much it costs, and when payment is due. Invoices create a clear, professional record for both sides and are often needed for bookkeeping, tax filing and following up on unpaid work.

How PDF invoices work
When you click Download PDF, QuickInvoice renders your invoice exactly as shown on screen and generates a PDF file directly in your browser. Nothing is uploaded to a server — the file is created on your device and downloaded straight to it, so your business and customer data stay private.
How to make an invoice look professional
- Add your logo so the invoice is instantly recognizable as coming from your business.
- Keep item descriptions specific rather than vague ("Logo design — 3 concepts" instead of "Design work").
- Use a consistent invoice numbering system so invoices are easy to reference later.
- State your payment terms clearly, including the due date and accepted payment methods.
- Proofread names, amounts and dates before sending — small errors delay payment.
Common invoice mistakes to avoid
- Forgetting to include a due date, which makes it unclear when payment is expected.
- Reusing the same invoice number, which causes confusion in your records.
- Leaving out contact details, so the customer can't easily reach you with questions.
- Mixing up subtotal, tax and total, which can make the final amount unclear.
