Fixed price vs day rate for web projects: what to expect

Most web agencies and freelancers offer either a fixed price or a day rate. Both are legitimate. They suit different situations, and the wrong choice for your project can cause friction that has nothing to do with the quality of the work. Here's how to think about it.

What fixed price means in practice ¶

A fixed-price project starts with a written scope document. The scope defines exactly what will be delivered, by when, and at what cost. If the scope changes, the price changes, and that change is agreed in writing before the work continues.

The advantage for clients is predictability. You know the total cost before any work begins. The disadvantage is that fixed-price projects require a clear brief upfront. If you're still figuring out what you need, a fixed scope can feel constraining.

What a day rate means in practice ¶

A day rate project bills for time spent rather than deliverables. The agency or developer works on your project and invoices at the end of each week or month. The total cost depends on how long the project takes.

This structure works well when the scope is genuinely unclear at the start, or when the work is exploratory. It's also common for ongoing support and maintenance. The risk is that costs can exceed initial estimates if the project turns out to be more complex than expected.

Which one to ask for ¶

If you have a clear goal and can describe what you need in writing, ask for a fixed-price proposal. It protects you from cost overruns and forces the agency to think carefully about scope before the project starts.

If you're in an early stage and still working out what you need, a short day-rate engagement to produce a brief or a prototype can be a sensible first step before committing to a larger fixed-price project.

• Clear goal, defined deliverables: ask for fixed price
• Exploratory work or unclear scope: day rate for a defined phase
• Ongoing maintenance: day rate or monthly retainer
• Large project with phased delivery: fixed price per phase

The structure matters less than the clarity of the agreement. Whatever you choose, make sure the deliverables and the payment terms are written down before work starts.
