What is an Invoice Generator?
An invoice generator is a tool that helps freelancers, small businesses, and agencies create professional, itemized bills for their customers without design software or accounting experience. The CrazyGamesUp Invoice Generator runs entirely in your browser: you fill in your business details, add line items, and get a print-ready invoice you can send or save as a PDF in minutes.
How to create an invoice
- Add your business details. Enter your company name, address, contact information, and an optional logo.
- Add your customer's details. Fill in who the invoice is billed to.
- Set the invoice details. Choose an invoice number, dates, currency, and payment terms.
- Add line items. List each product or service with quantity, unit price, tax, and any discount — totals calculate automatically.
- Add payment details. Include your bank information or a QR code so customers know how to pay.
- Print or export. Use Print / Save PDF to generate a polished A4 invoice, or download your data as JSON to edit later.
