Free invoice generator

1. Enter your business name and contact details, and the client you are billing.
2. Set the invoice number, issue date, and optional due date.
3. Add one line per item you are charging for — description, quantity, and rate.
4. Optionally set a tax percentage; the subtotal, tax, and total calculate live.
5. Download the PDF or print it straight from your browser.

Once you have sent a few, the whole loop takes under two minutes per invoice. The fields pre-fill sensibly (today's date, a starting invoice number), so you are usually just typing the new line items and the client name.

An invoice is a legal request for payment, and a clear one gets paid faster than a confusing one. Every invoice should contain a small, fixed set of parts; anything beyond that is either helpful context or clutter.

The essentials

• Who it is from. Your business name and a way to reach you — email and phone at minimum. Without this, the client cannot ask questions or pay.
• Who it is to. The client or company being billed. This matters for their bookkeeping as much as yours.
• A unique invoice number. So you and the client can refer to this specific invoice without ambiguity, and so your records sort cleanly.
• The date issued and when it is due. The due date is what makes an invoice a commitment rather than a wish.
• Line items. One row per thing you are charging for, with a description, quantity, and rate. Vague single-line invoices (‘Services rendered — $1,500’) get queried and delayed far more often than itemized ones.
• The totals. Subtotal, any tax, and the total due, stated plainly.
• How to pay. In the notes: the methods you accept and the details for each.

What to leave off

Avoid embedding sensitive details beyond what the client needs to pay — full bank account numbers if a routing number alone suffices, for instance. Do not use the invoice as a marketing flyer; keep it clean. And do not include personal notes or commentary; an invoice can be shown to accountants, bookkeepers, and partners, so write it as if a third party will read it.

A well-formatted invoice is necessary but not sufficient. The businesses that get paid quickly share a few habits that have nothing to do with the PDF itself.

• Send the invoice immediately. The same day you deliver, if possible. Every day you delay sending is a day added to when you get paid, plus it signals that payment is not urgent to you.
• State the due date explicitly. ‘Due on receipt’ or ‘Net 14’ on the invoice removes ambiguity. Invoices without a due date float indefinitely.
• Make paying frictionless. Offer the method your client prefers, and put the details right on the invoice. A payment link or a card option gets paid faster than a bank transfer every time.
• Follow up politely and early. A friendly reminder the day after the due date catches most late payments, which are usually an oversight rather than a refusal. Waiting two weeks to follow up quietly communicates that you do not mind waiting.
• Itemize clearly. Clients question invoices they do not understand, and a question delays payment. A line per charge with a plain-English description prevents most queries before they happen.

The bookkeeping around invoices is unglamorous and worth getting right early, because fixing a tangled records system later is painful. Three rules cover most of it.

First, never reuse an invoice number. The number is the handle by which you and the client (and your accountant) refer to the document; duplicates make that impossible. If you make a mistake on an invoice you have already sent, issue a corrected one with a new number and mark the old one void, rather than editing the original.

Second, keep a single list of every invoice you issue — number, client, amount, date sent, date paid. A spreadsheet is enough to start. The point is that at any moment you can answer ‘which invoices are outstanding and for how much’ without digging through your email.

Third, save a copy of every PDF you send, in one place. When a client asks about an invoice months later — and they will — you want the exact document you sent, not a reconstruction.

An invoice is a formal request for payment for work already done or goods already delivered. It is not a contract, a quote, or a receipt. A quote (or estimate) tells a client what you will charge before they agree; an invoice tells them what they owe after they have agreed; a receipt confirms they have paid. Mixing these up causes real confusion.

This generator produces invoices only. If you need to send a quote first, write that separately — an email or a one-page document describing the scope and the price. Once the client agrees and the work is done, you issue the invoice. This sequencing protects you: you never start work on the basis of an invoice, and you never collect payment on the basis of a quote.

And to repeat the honest boundary: this tool does not move money. It produces the document that asks for money. Payment flows through whatever processor you use — a card processor, a payment app, a bank transfer — and the invoice simply tells the client where to send it.

Most independent businesses lose money not because their pricing is wrong but because the conversation around money is uncomfortable, so they avoid it, and avoidance costs them. A clear, professional invoice is one of the tools that makes the money conversation less personal and more routine — which is exactly what makes it easier.

Start with a deposit for any non-trivial job. Asking for a percentage of the total upfront, with the balance invoiced on completion, is standard in trades, consulting, and custom work. A deposit filters out clients who were never going to pay, and it means that by the time you send the final invoice, the client has already committed financially. State the deposit in your quote, then reflect it as a line on the final invoice so the math is visible and unambiguous.

Put payment terms on every invoice, in writing. Whether you ask for payment on receipt or net fourteen, stating it removes the most common cause of late payment, which is genuine uncertainty about when the client was supposed to pay. Clients rarely pay late on purpose; they pay late because nothing told them it was due. A due date and a preferred method on the invoice close that gap.

When a payment is late, follow up early and without apology. A short, friendly note the day after the due date — attached to the invoice itself — resolves the majority of late payments, which are oversights. Waiting two weeks out of a desire not to seem pushy quietly teaches clients that your deadlines are suggestions. Politeness and firmness are not in conflict; a clear, kind reminder that references the invoice number and due date is both.

Think about how you price before you invoice, because the invoice is where pricing becomes real. The two reliable models are hourly, where you bill for time and trust the client to respect it, and fixed-fee, where you quote a total for a defined scope and the client knows the cost up front. Hourly protects you against scope creep but invites scrutiny of every hour; fixed-fee sells cleanly but punishes you when a job runs long. Most seasoned operators blend them — fixed-fee for the predictable core of the work, hourly or a change-order for anything that expands beyond it. Whichever you choose, the invoice should reflect it transparently so the client never feels surprised by the total.

Finally, keep your records clean enough that you can answer the basic question instantly: who owes me, how much, and since when. If that question takes more than a minute to answer, your system — however informal — is leaking money. The invoice you send is the start of a tiny workflow that, run consistently, is the difference between a business that gets paid and one that hopes to. And at tax time, a clean run of numbered invoices is the single best record you can hand an accountant — far better than a pile of unnumbered emails, and worth the small discipline of numbering and filing each one as it goes out.
