Free Invoice Generator

Create a PDF invoice online

Use the invoice generator when you need a clean PDF invoice for freelance work, contractor jobs, consulting, services, retainers, deposits, or project milestones. Add your business details, client information, line items, taxes, discounts, shipping, payment terms, and notes, then download the document from the live preview.

What to include on an invoice

A useful invoice should include the invoice number, issue date, due date, seller and buyer details, line items, currency, subtotal, taxes or discounts, total due, and clear payment instructions. If your client uses a finance or AP team, include the PO number, project name, billing contact, and payment reference when they apply.

Use templates without losing control

Start with an invoice template for your industry, then edit the fields so the document matches the actual work. Templates help you avoid blank-page setup, but the final invoice should still use clear line item names, accurate quantities, and payment terms your client already understands.

Before you download and send

Check that the client name matches the agreement, the due date is realistic, the total matches the line items, and payment instructions are easy to find. If the client requires a PO number or bank transfer details, make those fields easy for accounts payable to copy. Drafts stay on your device for no-signup use, so you can return later without turning invoice details into account data.

Invoice fields explained

A good invoice is easy for both the client and their finance team to understand. These are common invoice fields, not tax or legal advice, and the exact fields you need may vary by client, country, and business type.

Invoice generator vs invoice template

The invoice generator is the editable tool where you create the final PDF. Invoice templates are starting points for layout, industry wording, or common fields. Pick a template when you want a faster setup, then use the generator to edit details, check totals, and download the finished invoice.

Common mistakes before sending

• Using a vague line item such as services without the work period or deliverable.
• Sending an invoice without a due date, payment terms, or payment instructions.
• Forgetting a PO number or buyer reference for clients with finance teams.
• Changing invoice numbers after sending the document to the client.
• Treating a template as tax or legal advice instead of a starting point for common invoice fields.
