What is a hourly invoice template?
An hourly invoice template bills a client for time worked, showing hours multiplied by your rate for each task. It is the standard invoice for freelancers, consultants, contractors, agencies and anyone who charges by the hour.
A good hourly invoice makes the time transparent: it lists what you worked on, how many hours each task took, and your rate, so the total is easy to verify and approve. Pair it with a timesheet to track the hours first.
What to include in a hourly invoice
An hourly invoice should make the time and the rate clear:
- Your business details: Your legal or trading name, address, email, phone and logo, so the client knows exactly who to pay
- The word "Invoice" and a unique invoice number: A clear label and a sequential number (for example INV-0001) that you can reference in your records and the client can quote when paying
- Client details: The customer's name or company, billing address and contact, so the invoice reaches the right person
- Invoice date and due date: The date issued and the date payment is due, plus your terms such as Net 15 or Net 30
- Tasks with hours and rate: Each task or day with the hours worked, your hourly rate, and the line total (hours times rate)
- Total hours: The sum of hours billed, so the client can reconcile it against their own records or your timesheet
- Subtotal, tax and total due: The subtotal before tax, any sales tax applied, and the final amount owed in bold
- Payment terms and methods: How you accept payment (bank transfer, card, check), late-fee terms, and a short thank-you note

When a hourly invoice template is not enough
A hourly invoice template is a fine way to send a clean, professional bill. What it cannot do is keep track of what you have invoiced, chase the payments that are late, and tie every paid invoice back to your books. That work grows quietly as your business does.
FinStackk is an accounting and tax compliance platform for U.S. businesses, and its bookkeeping module, Fin-Books, takes that work off your plate. The Fin-Books team manages customer invoicing, invoice follow-ups, accounts receivable and reconciliation as part of your monthly books, so revenue is recorded correctly and nothing falls through the cracks.
That matters most when invoices turn into tax and compliance obligations: recognizing revenue in the right period, reconciling deposits, tracking sales tax you collect, and keeping GAAP-ready financials for a lender or investor. If you have outgrown filling in a template by hand, that is the point to move from a blank file to managed books.
Common mistakes to avoid on a hourly invoice
- No task detail: Group hours by task or day with a short description; a single lump of hours invites questions
- Rounding inconsistently: Pick one rounding rule (for example to the nearest quarter hour) and apply it every time
- No timesheet backup: Keep the timesheet behind the invoice in case the client asks for detail
- Unclear rate: State your hourly rate plainly, and any different rates for different work
Frequently asked questions (FAQ)
How do I invoice by the hour?
List each task with the hours worked and your rate, let the line total calculate as hours times rate, sum the hours and amounts, add any tax, and send. The generator above does the math for you.
Should I attach a timesheet?
It helps. Track hours on a timesheet first, then transfer the billable totals to the invoice. Clients approve detailed hourly invoices faster.
Can I bill different hourly rates on one invoice?
Yes. Use a separate line for each rate (for example design vs. revisions) so the client sees how each total was reached.
Is this hourly invoice template free?
Yes. Download it in Excel, Word or PDF, or fill it in online, at no cost.
Can I use AI or ChatGPT to create an invoice?
You can ask an AI tool to draft invoice wording, but it will not reliably calculate your totals or tax, and it keeps no record of what you have billed. A ready-made template, or the generator above, is faster and more accurate for the invoice itself. For the accounting behind your invoices, recording the revenue, reconciling the payment and tracking what clients owe, FinStackk's Fin-Books handles that as part of your US bookkeeping.
Which format should I use: Word, Excel, PDF, or Google Docs and Sheets?
Use Word or Google Docs when you want to type into a document and control the layout. Use Excel or Google Sheets when you want the line totals, subtotal and tax calculated for you. Use the PDF when you just need a fixed file to print or send. Many businesses keep an editable master in one format and send a PDF to the client.
How do I get paid faster, and what should I do about late payments?
Send the invoice the day the work is done, set short and clear terms such as Net 15, make payment easy, and follow up politely the day after the due date. As your invoice volume grows, chasing payments by hand gets expensive. FinStackk's Fin-Books manages customer invoicing, invoice follow-ups and accounts receivable, so late invoices get chased and your books stay current.
Do I need to charge sales tax on an invoice?
It depends on what you sell and where the customer is. Many professional services are not taxed, but most states tax physical goods and some tax specific services. If you have sales tax nexus in a state and sell something taxable there, you generally collect and remit the tax. FinStackk's Fin-Tax helps US businesses identify and manage their sales tax obligations as they grow.
How do I handle different hourly rates on one invoice?
Put each rate on its own line (for example design at one rate and revisions at another) with the hours and rate shown, so the client can see how each total was reached. Track the hours on a timesheet first, then move the billable totals onto the invoice.
