How to Invoice for Fixed-Price Projects (Without Tracking Time)

By Yufan Chen · 6 min read

Not everyone bills by the hour. Designers, developers, writers, and agencies often quote a single flat fee for the whole project — and clients love the predictability. The catch is that you still need to send a professional invoice, and most invoicing tools assume you tracked time to get there. You don't have to.

If you charge a fixed amount per project, here's how to send a clean, branded PDF invoice without starting a single timer.

Why fixed-price billing works

• Predictable for the client. They know the total up front, with no surprise hours.
• It rewards your efficiency. Finish faster and you earn the same — your expertise is the value, not your hours.
• Less admin. No timers, no timesheets, no reconstructing your day.

The one thing fixed-price work doesn't remove is the need to bill professionally and get paid on time.

The invoicing problem for fixed-price work

When you don't track time, your invoice usually becomes a Word document or a spreadsheet you reformat for every client. It works, but it looks ad hoc, it's slow, and it makes following up on payment awkward. A clean, branded PDF invoice signals that you're a professional — and it's faster to produce than wrestling with a template every time.

What a good fixed-price invoice includes

• Your branding — logo, business name, and address
• The client's details
• A clear line item describing the project and the fixed amount
• An optional discount
• A total, an invoice number, and a due date

How to invoice a fixed-price project in Tally — no time tracking

You can use Tally purely as an invoicing tool and never start a timer:

1. Add the client.
2. Create a project, turn on "Fixed fee," and enter your flat amount — say, $3,000 for a website build.
3. Add a discount if you want one.
4. Open the invoice preview, check it, and send the PDF — by email, share, or print — right from the app.

That's the whole flow. No hours, no timesheets — just a professional invoice for the amount you agreed on, with your branding on top.

Mixing fixed-fee and hourly work

Real-world work rarely fits one model. Some projects are flat-fee, others are hourly, and some are a flat fee with extra hours beyond a cap. Tally handles all of them: set a fixed fee per project, bill others by the hour, and even cap the hours included in a fixed fee — so every client gets the right invoice from a single app.

The bottom line

If you charge by the project, you don't need a time tracker — you need a fast way to send a professional invoice and get paid. Tally does exactly that in a few taps, and it's free to start.
