What is an invoice?

An invoice is a document a seller sends to a buyer to request payment for goods or services. It records what was provided, how much is owed, and when payment is due. Unlike a receipt, which confirms a payment already made, an invoice is the request for payment itself.

A clear, professional invoice does more than ask for money. It sets payment expectations, gives your client's accounts team everything they need to pay you, and gives you a clean record for your own bookkeeping and taxes.

What to include on an invoice

Most invoices, in any country, share the same core elements. A complete invoice includes:

  • Your business name, address, and contact details, plus your logo if you have one.
  • The client's name and billing address.
  • A unique invoice number and the issue date.
  • A due date or payment terms, such as “Net 15” or “Due on receipt”.
  • An itemised list of what you are billing for, with quantity, rate, and line total.
  • The subtotal, any tax (GST, VAT, or sales tax), discounts, and the total amount due.
  • Your payment details: a bank account, a UPI ID, or a payment link.
  • Your tax registration number where required, such as a GSTIN, VAT number, ABN, or EIN.

You can make and download an invoice here in under a minute:

  • Add your business name, address, and logo. These are saved in your browser, so your next invoice already carries your letterhead.
  • Choose your country to apply the correct currency, tax, and tax-ID labels automatically.
  • Enter your client's details and a unique invoice number.
  • Add a line for each item or service with a quantity and rate. The totals update as you type.
  • Turn on tax, a discount, or shipping if you need them, and add your payment details.
  • Download the PDF and send it to your client, or print it.

Invoice vs quote, estimate, and receipt

These documents are easy to confuse, but each has a distinct job. An estimate is an approximate, non-binding projection of cost before work begins. A quote is a firm price you commit to. An invoice is the bill you send once work is done or delivery is agreed. A receipt confirms that a payment has been made.

A single job often moves through several of them: an estimate or quote to win the work, an invoice to bill for it, then a receipt once the client pays. You can switch between all of these here without re-entering your details.

How to get paid faster

A few habits make a real difference to how quickly you are paid:

  • Send the invoice promptly, ideally the day the work is delivered.
  • Set clear, short payment terms and state the due date plainly.
  • Make paying easy with a bank account, a UPI QR code, or a payment link.
  • Use a consistent, sequential invoice number so nothing gets lost.
  • Add a short, polite note with your terms and a thank-you.

Common invoicing mistakes to avoid

  • Leaving off a unique invoice number, which makes invoices hard to track and reconcile.
  • Forgetting the due date, so the client has no deadline to work to.
  • Getting the tax treatment wrong, or omitting a required tax registration number.
  • Vague line items that invite questions and delay payment.
  • No clear payment method, so the client has to stop and ask how to pay you.

Common questions

What format is the invoice?

A clean, professional PDF that you can download and send by email, or print. The layout follows standard invoice conventions.

Can I add GST, VAT, or a UPI QR code?

Yes. Choose your country to apply the right tax, add your GSTIN, VAT number, or ABN, and enter a UPI ID to show a scan-to-pay QR on the invoice.

Can I invoice as an individual, without a registered company?

Yes. Freelancers and sole traders invoice under their own name every day. Use your own name and contact details in place of a company name, and add a tax ID only if you are registered for one.

How should I number my invoices?

Use a simple, sequential scheme like INV-0001, INV-0002, and never reuse a number. A consistent sequence keeps your records clean and makes invoices easy to find. This tool increments the number automatically each time you start a new one.

When should I send an invoice?

As soon as the work is delivered or the goods are shipped, unless you agreed on a schedule such as monthly or on milestones. The sooner you invoice, the sooner you are paid.

What are payment terms and a due date?

Payment terms say how long the client has to pay, for example “Net 15” (15 days) or “Due on receipt”. The due date is the calendar date that period lands on. Both set a clear expectation for when you should be paid.

How do I correct or cancel an invoice I already sent?

Do not delete a sent invoice. Issue a credit note that references the original to cancel or reduce it, then send a corrected invoice if needed. This keeps both sets of records traceable.

Can I use this for freelancing, agencies, or other kinds of work?

Yes. Freelancers billing by the hour, consultants invoicing by the day, agencies sending retainers, and small businesses shipping goods all use the same editor. You can also switch the document type to send estimates, quotes, receipts, credit notes, or proforma invoices.

Is it really free?

Yes. Create and download as many documents as you like, with no account, no trial, and no watermark on the document itself.

Is my data safe?

Completely. Everything is built in your browser. Your logo, client details, and amounts are never uploaded to a server, so they never leave your device.

Do I need to sign up?

No. Just start typing. Your business details are saved locally in this browser, so your letterhead is ready the next time.
