## Question

Fixed fee vs retainer contracts: how do we decide what's right?

## Answer

First, let's clear up the words. Fixed fee and fixed price are the same thing — some people say fee, some say price, but either way it means we agree on a scope and a number before any work starts. A retainer means you pay for ongoing access, usually monthly, and the work flows inside it.

Fixed fee works best when there are still unknowns and we need to control risk. Retainers work best when the work is ongoing, priorities change often, and you want steady access to the same person over time.

Early product work usually fits fixed-fee phases better. At that stage, the main job is learning what the product actually needs, not pretending everything is stable before it is.

The worst situation is both sides committing to unknown time and unknown cost. That is how projects fall apart.

## Which One Is Usually Cheaper?

Here's the honest answer: the retainer usually looks cheaper per month, and the fixed fee is usually cheaper overall.

That's because a fixed fee forces scope. We have to decide what matters before the clock starts, and that decision is where the savings live. A retainer without a clear destination has a way of quietly billing you for wandering.

Don't kid yourself though — a fixed fee only stays cheap when the scope stays honest. If you keep stuffing changes into the same phase, you're just paying for negotiation instead of wandering. Changes go into the next phase. That's the deal that keeps the price fixed.

## How to Choose

Fixed fee is for clarity, retainers are for steady progress on a known path. If we're still shaping the product, deciding what matters, and trying to reduce waste, I'd lean fixed fee. If the product is already live, the priorities are clearer, and you mostly need steady momentum, a retainer can make sense.

We choose based on where your idea is in its life cycle, not based on which billing model sounds more grown up.
