Early in my career, I billed by the hour. It's what everyone did, so I did it too. And I noticed something uncomfortable pretty quickly.
When you bill hourly, efficiency is punished.
If I figured out the answer to a client's problem in two hours instead of ten, I got paid less. If I'd already solved a similar problem for another client and could apply that knowledge immediately, I got paid less. My experience and speed, the things that made me better at the job, were working against my income.
That's a broken model. So I stopped using it.
The incentive problem
Let's talk about what hourly billing actually incentivizes, even when nobody intends it to.
The consultant is incentivized to take longer. Not necessarily to pad hours consciously, though that happens. But there's no structural reward for being fast, efficient, or decisive. Every additional meeting, every extra round of analysis, every "let's dig a little deeper" puts more money in the consultant's pocket. The incentive to wrap things up efficiently simply isn't there.
The client, meanwhile, is incentivized to limit engagement. Every time you ask a question, the meter's running. Every time you want to talk something through, it costs money. So you hold back. You batch your questions. You try to squeeze value out of every minute. Instead of a natural, collaborative working relationship, you get a transactional one where both sides are watching the clock.
Neither of these dynamics leads to good work.
What fixed price changes
When I quote a fixed price for a project, the dynamics flip.
I'm incentivized to be efficient. If I can solve your problem faster because I've seen it before, great. I make the same money and you get results sooner. My experience works for both of us instead of against one of us.
You're incentivized to engage fully. Ask as many questions as you want. Call me when something comes up. Don't hold back a concern because you're worried about the bill. The price is the price. More communication leads to better outcomes, and nothing about the pricing discourages it.
We're both pointed in the same direction: get this done well.
"But what if the project takes longer than expected?"
This is the obvious question, and it's fair. If the price is fixed, who absorbs the risk of things taking longer?
Mostly, I do. And I'm okay with that, because I'm the one who scoped the project. If I underestimate how long something will take, that's on me. I should have asked better questions upfront, or built in more buffer, or been more realistic about the complexity.
That said, I protect against this in a few ways.
I scope carefully. Before I quote a price, I spend real time understanding what's involved. I ask a lot of questions. I think about what could go sideways. I've done this enough times that my estimates are usually in the right range.
I define scope clearly. The agreement spells out exactly what's included and what's not. If something comes up mid-project that's genuinely outside the original scope, we have a conversation about it. Sometimes I absorb it because it's minor. Sometimes we agree to adjust the scope and price together. Either way, nobody's surprised.
And I build in margin. Not a lot, but enough to handle the normal friction of working with real humans in real businesses. Things never go exactly as planned. The price accounts for that.
How I actually scope a project
The scoping conversation is the most important part of the whole process. Get it right and everything flows. Get it wrong and someone's unhappy.
I start with a conversation about what you need. Not what you think you need, necessarily, but what's actually going on. What are the problems? What have you tried? What does "success" look like? What are your constraints, whether that's money, time, people, or all three?
Then I go away and think about it. I figure out what needs to happen, how long it'll reasonably take, what resources are required, and what the risks are. I think about similar projects I've done and what I learned from them.
Then I come back with a price and a scope. Here's what I'll do, here's what you'll get, here's what it costs, here's how long it takes. If that works for you, we move forward. If it doesn't, we can adjust the scope until it does.
What I won't do is give you a number I don't believe in just to win the project. If I quote a price, I'm confident I can deliver at that price. If I'm not confident, I'll tell you, and we'll figure out what to do about it.
The objections I hear
"Isn't it more expensive than hourly?" Sometimes, on paper, yes. If a project could theoretically be done in 15 hours and my fixed price is equivalent to 20 hours, you might think you're overpaying. But you're not comparing equivalent things. You're comparing a known cost to an unknown one. With hourly billing, that "15-hour" project might end up being 25 hours. You don't know. With fixed price, you know exactly what you're paying.
"What if we don't use all the time?" There's no "time" to use. You're not buying hours. You're buying an outcome. If I deliver that outcome efficiently, that's a good thing for both of us.
"Don't you make more money on easy projects?" Sure. And I make less on hard ones. Over time, it averages out. More importantly, it means I'm not penalized for being good at my job, which keeps me motivated to do my best work on every project.
When fixed price doesn't work
I'll be honest, there are situations where fixed price doesn't make sense. If the scope is truly unknowable, meaning if we genuinely can't define what "done" looks like before we start, then fixed pricing is just guessing.
That's rare in the kind of work I do. Most operational improvements have a definable scope. But if I encounter a situation where fixed pricing doesn't fit, I'll say so rather than force it.
For most small business consulting, though, fixed price is better. Better for you because you know what you're spending. Better for me because my incentives are aligned with yours. Better for the work because neither of us is watching the clock.
