Free Hourly Invoice Generator — Bill by the Hour, No Signup
By Innvoic
An hourly invoice lists the hours you worked, your rate, and the total. It’s how freelancers, consultants, and contractors bill for time. With Innvoic’s free hourly invoice generator, you set the unit mode to Hours, type in your time entries, and the math handles itself. Download a PDF or email it to your client.
How to create an hourly invoice
- Set the unit mode to Hours. Open a new invoice and switch the unit mode from Qty to Hours. Each line item now takes hours instead of units, and the amount becomes hours × your rate, calculated automatically.
- Add one line per task or workday. Write what you did (“Homepage wireframes,” “Client call, March 3”), the hours, and your rate. Timesheet-style lines get approved faster because the client sees exactly where the time went.
- State your rounding and minimum rules. Most hourly billers round to the nearest quarter hour and set a one-hour minimum for small tasks. Put that policy in the notes section so nobody argues about it later.
- Bill expenses on separate lines. Mileage, software, or materials go on their own lines. That keeps your hours clean and easy to audit if a client ever questions them.
- Download the PDF or email it. Everything runs locally in your browser, so your client list and rates stay on your computer. Send it with a due date and your payment details filled in.

Frequently asked questions
Should I round my hours on an hourly invoice?
Yes, and almost everyone rounds to the nearest quarter hour. A 20-minute call becomes 0.5 hours, a 40-minute task becomes 0.75. The key is stating the policy on the invoice itself so the client sees it’s systematic, not padded.
What’s a fair minimum billing increment?
One hour is standard for consultants and designers; 15 minutes works for ongoing clients you bill weekly. Whatever you choose, agree on it before the work starts and print it on every invoice. Surprise minimums are what start disputes.
How do I track hours without forgetting half of them?
Log time daily, not weekly. Memory lies after 48 hours. Even a notes app with “Mar 3: wireframes 10:00–16:30” is enough. When you sit down to invoice, you’re copying from notes instead of reconstructing from memory.
Should I charge for quick emails and short calls?
It depends on the relationship. Many freelancers bundle emails under 10 minutes into the project and bill calls longer than 15 minutes. Pick a rule, tell the client up front, and apply it consistently. Consistency matters more than which rule you pick.
Is a retainer better than hourly billing?
Retainers give you predictable income; hourly is fairer when the workload swings month to month. Plenty of freelancers mix both: a small monthly retainer covering a set number of hours, then hourly billing beyond that. Saved line items and one-tap invoice duplication make either pattern easy.
What if a client disputes my hours?
Detailed line items are your best defense. “Mar 3: Homepage wireframes, 6.5 hrs” is much harder to argue with than “Design work: 10.5 hrs.” If disputes keep happening with the same client, that’s a sign to move them to fixed-price quotes instead.
