How to make an hourly invoice

An hourly invoice is simple at its core: for every task, you multiply the hours you worked by your rate, add the lines together, apply any tax, and you have your total. The template above does that arithmetic the moment you type, so you can focus on getting the details right instead of fighting a spreadsheet.

Fill in your business and client details, add a line for each chunk of work with the hours and your rate, set a tax rate if you charge one, and download. That's the whole job — usually under two minutes for a repeat client.

What every hourly invoice should include

• Your business details — name, address, email and phone so the client knows exactly who to pay and how to reach you.
• The client's details — the correct legal name and contact; getting this wrong delays payment.
• A unique invoice number — sequential (INV-0001, INV-0002…) so you and the client can reference it.
• Invoice date and due date — "Net 14" or "Net 30" sets a clear expectation.
• Itemised hours — a separate line per task with hours and rate. Detail builds trust and heads off "what was this for?" questions.
• Subtotal, tax and total — clearly separated so the math is obvious.
• Payment terms and instructions — how to pay, and what happens if it's late.

Tracking hours the right way

Bill in decimal hours, not minutes: 15 minutes is 0.25, 30 is 0.5, 45 is 0.75. Most clients expect rounding to the nearest quarter-hour. Track time as you go rather than reconstructing it at month-end — reconstructed time is almost always under-billed, and it's the single biggest leak in an hourly business.

If a task ran long because of something outside the original scope, give it its own line with a short note. Transparent itemisation is what turns a surprising total into an approved one.

Five ways to get paid faster

1. Send it the day the work ships. Invoice-to-send lag is the most controllable delay there is.
2. Use short terms. Net 14 gets paid sooner than Net 30; "due on receipt" sooner still.
3. Make paying effortless. Put bank details or a payment link right on the invoice.
4. Number everything. A clear invoice number makes follow-up painless for both sides.
5. Automate the nudge. A polite reminder the day after the due date recovers most late invoices.

PDF, Word or Excel — which should you send?

PDF is the default for sending to clients: it looks identical everywhere and can't be edited by accident. Word is handy when you want to tweak wording or save a reusable master. Excel/CSV is for your own records and bookkeeping — drop the line items straight into your accounting sheet. This template gives you all four from the same filled-in invoice.
