Are Invoice Fly’s document generators really free?

Yes! All 11 of Invoice Fly’s document generators are completely free to use. You can create estimates, quotes, invoices, receipts, work orders, purchase orders, and other business documents without paying a fee or creating an account. Simply choose the generator you need, enter your details, and download your completed document as a PDF. There are no sign-up requirements to get started.

What’s the difference between a document generator and a template?

A document generator creates a finished document using the information you enter online. Add your business details, client information, products or services, quantities, and prices, and the generator automatically calculates the totals where applicable. You can then download your completed document as a PDF, ready to send or print.

A template, on the other hand, is a blank document that you download and edit yourself using compatible software. It’s useful if you prefer to work offline or want more control over the layout and content. Invoice Fly offers free templates in Word, Excel, PDF, Google Docs, and Google Sheets formats. Browse our free business templates to find one that suits your needs.

Should I send an estimate, a quote, or an invoice?

The right document depends on where you are in the job.

  • Estimate: Send an approximate breakdown of expected costs before work begins. The final price may change if the scope, materials, or requirements change.
  • Quote: Provide a fixed price for the agreed work or services. Your client can review and approve the price before you start.
  • Invoice: Send an invoice when payment is due, usually after completing the work or reaching an agreed payment milestone.

Using the right document helps set clear expectations, avoid pricing misunderstandings, and keep your billing organized. Read our guide to invoice vs. quote to understand when to use each.

When should I use a proforma invoice?

A proforma invoice is a preliminary document that outlines the expected cost of goods or services before a sale is finalized. You can send one when a client needs a formal breakdown of proposed costs before confirming an order, approving a budget, arranging payment, or making a deposit.

Unlike a final invoice, a proforma invoice is not a request for payment for completed work. It gives both parties an opportunity to review the prices, quantities, and terms before moving forward. Once the transaction is confirmed and the goods or services are delivered, you can issue the final invoice.

Can I add my business logo to an invoice?

Yes. Invoice Fly’s free invoice generator lets you upload your business logo and customize the invoice style and color before downloading it. Adding your logo helps make your invoice look professional and consistent with your business branding.

For a complete invoice, include your business and client details, a unique invoice number, issue date, payment due date, descriptions of the work or products supplied, quantities, prices, applicable taxes, and the total amount due. Review everything before downloading your ready-to-send PDF invoice.

Can I use Invoice Fly’s free generators on my phone?

Yes. Invoice Fly’s free document generators run directly in your web browser, so you can use them on your phone, tablet, or computer without installing an app. Whether you’re on a job site, meeting a client, or working from your office, you can open a generator, enter the required details, and download your document when you’re ready.

The generators are also free to access without creating an account, making it easy to prepare business documents wherever you have an internet connection.

How can I manage my invoices, track payments, and get paid?
