The short answer
Fixed price gives you a known number upfront and pushes the estimating risk onto the developer, but it only works when the scope is clear. Hourly is fairer for genuinely unknown or evolving work, though you carry the risk if it runs long. For most defined small-business projects, fixed price is the safer default. Neither model is a scam.
Key takeaways
- Fixed price = known cost, risk on the developer, but it needs a clear scope to be honest.
- Hourly = flexibility for unknown work, but the overrun risk sits with you.
- For a defined small-business project, fixed price is usually the safer default.
- Hourly isn't a red flag. For genuinely exploratory work it's often the fairer, cheaper model, as long as there's a cap.
- The danger isn't the pricing model, it's using the wrong one for how well-defined your project actually is.
When you go to hire a developer, you'll run into two ways of paying: a fixed price for the whole project, or an hourly rate for however long it takes. It's tempting to assume fixed price is always safer and hourly is a trap that lets a developer run up the meter. That's not quite right. Both models are honest, both can be abused, and the right choice depends less on the developer and more on how well-defined your project is. Pick the wrong one for your situation and you'll either overpay for padding or watch an open meter spin.
We quote fixed prices, so you know our lean. We'll still make the honest case for when hourly is the better deal for you.
The two models, side by side
| Factor | Fixed price | Hourly |
|---|---|---|
| What you know upfront | The total cost | The rate, not the total |
| Who carries the risk | The developer | You |
| Needs a clear scope? | Yes, absolutely | No, handles fuzzy work |
| Handles changes | Via change orders, repriced | Naturally, just more hours |
| Incentive to watch | Developer wants efficiency | You must watch the hours |
| Best for | Defined projects | Exploratory or evolving work |
| The risk to you | Padding baked into the quote | An open meter running long |
We highlighted fixed price because it's the safer default for most small-business projects, but read the 'best for' row before you assume it's always right. If your project genuinely can't be defined yet, forcing it into a fixed price just means the developer pads the number to cover their risk, and you pay for uncertainty either way.
When fixed price is the better deal
Fixed price shines when you know what you want. You've got a clear scope, the project has a definable end, and you'd rather have one number to budget around than a meter you have to watch. The developer commits to that number, which means the risk of a bad estimate is theirs, not yours. If it takes them longer than they thought, that's their problem, not your invoice. This is genuine protection, and it's why fixed price suits owners who want certainty and don't want to manage the work hour by hour. The catch: it only works with a solid scope document, because a fixed price on a vague description is a fixed price on a misunderstanding.
When hourly is genuinely the honest choice
Now the part fixed-price shops don't emphasize. For truly exploratory work, hourly can be both fairer and cheaper. If nobody can say yet exactly what needs building, because you're figuring it out as you go, a fixed price forces the developer to guess high to protect themselves, and you eat that padding whether the risk materializes or not. Hourly means you pay for the actual work and nothing more. Good ongoing relationships, small evolving improvements, and research-heavy projects often run better hourly. The protection you want isn't to avoid hourly, it's a cap or a not-to-exceed ceiling, plus regular check-ins so the total never surprises you.
How each one can be abused
- Fixed price abuse: a lowball number to win the job, then aggressive change orders for anything not spelled out. Protection: a thorough scope and a clear change process.
- Hourly abuse: slow work, vague timesheets, and a meter that runs with no ceiling. Protection: a cap, itemized hours, and regular reviews of what you're getting.
- Either way: the real safeguard is transparency. A developer who's clear about what's included, what a change costs, and where the hours go is honest under either model.
The overrun risk is worth understanding on its own, since it drives which model protects you. See why software projects go over budget for the full picture.
How we price, and why
We quote a fixed price after a scoping call for our custom software work, because for a defined project it gives you the thing most small businesses want: a number you can budget around, with the estimating risk on us instead of you. If you ask for something outside the original scope, we price it as a change and you approve it before we build, so the number only moves with your say-so. For the ongoing changes after launch, where the work is naturally open-ended, we're happy to work on a retainer or hourly basis, because forcing that into a fixed number would just mean charging you for padding. The model should fit the work, not the other way around.
