How to Hire a Developer for a Small Project (10-50 Hours)

If you want to hire a developer for a small project and actually get your money's worth, keep the job narrow: one outcome you can describe on a single page, a cap on the hours, and a clear definition of done. Jobs of 10 to 50 hours, like an API integration, a new report in your admin panel or a batch of bug fixes, suit a freelance developer well, as long as you settle those three things before anyone writes code.

I take on jobs this size on existing Laravel and JavaScript apps, so read this with that bias in mind. I'll also be clear about when hiring someone like me is the wrong call.

The short answer: what fits in 10-50 hours

My rule of thumb: if you can describe the result on one page and one person on your side can sign it off in an afternoon, it probably fits in 10-50 hours. If it needs several decision meetings, design from scratch or changes across multiple systems, it's a project, and different rules apply. My guide to hiring a developer covers that whole process, from defining what you need to signing a contract.

The onboarding tax: why small jobs cost more than the hours suggest

On a 20-hour job, the fixed costs of getting started weigh far more than they do on a 300-hour project.

The first time a developer works in your codebase, time goes into getting access, running the app on their own machine and understanding how the pieces fit together. That time is roughly the same whether the job is big or small. On a large project it disappears into the total. On a 15-hour job it can be a noticeable slice of the invoice.

Communication works the same way. A kickoff call, a few clarifying questions and a walkthrough at the end barely register over a multi-month engagement. On a small job, they're a real line item.

What that means in practice:

• The better prepared you are, the more of the paid hours go to the actual work.
• Bundling several small requests into one job usually beats sending them over one at a time.
• Once a developer knows your code, every later job gets cheaper. That's a strong reason to stick with the same person if the work is good.

If the code was written by a developer who has since left, expect more onboarding time. And if the code doesn't live somewhere you control, that's the first problem to fix. My guide on switching developers mid-project walks through getting access and an overview in place, and most of it applies here too.

How to run a small project with a freelance developer: 6 steps

None of these steps needs technical knowledge. Most of them are about removing guesswork before the clock starts.

1. Describe the outcome, not the solution

Write down what should be different once the job is done, and for whom. "When an order is paid, automatically create an invoice in Xero with the customer's VAT number" is a good brief. "Build an integration" isn't.

Also write what's out of scope, such as refunds or historical orders. That single line often saves the most hours, because it kills assumptions. One page is plenty. Attach screenshots of the current workflow and a few examples of real data if you can.

2. Hand over access and context on day one

At a minimum, the developer needs access to your repository (where the code lives), a test environment and a description of how the app gets deployed. If you have a staging environment (a copy of the app where changes can be tested safely), say so. If you don't, setting one up might be the first part of the job.

Tell them who built the app and whether that person can answer questions. Every missing login on day one means waiting, and on a small job, waiting usually means it slips to next week.

3. Ask for a range and a cap, not a single number

A credible estimate for a small job is a range, say 14-20 hours, not one number. Ask the developer what would push it toward the high end. Then agree on a cap: the point where work stops and you decide together before any more hours are spent.

If the job is too fuzzy to estimate, pay for 1-3 hours of investigation first. It's cheaper than a guessed estimate.

4. Agree on what "done" means

Write 3-5 conditions that must be true before you sign off. For example: works in the test environment, checked by you with real data, deployed to production, and a short handover note written. Agree on who deploys and when. Friday afternoon is rarely a good time.

5. One decision-maker and a fixed rhythm

Small jobs stall when the developer is waiting for answers or when three people on your side each want something different. Pick one person who can make decisions, and agree on a rhythm, such as a short written update every other day. Daily stand-ups are overkill for a 20-hour job.

If you're in a different time zone, agree on a fixed daily window for questions. Between Central Europe and the US East Coast, that's usually the US morning.

6. Insist on a handover that outlives the job

A good handover is the code in your own repository, usually as a pull request (a bundled change that can be reviewed before it's merged), plus a short note: what changed and why, how it was tested, and what was deliberately left out. That note is what makes the next job cheaper, even if a different developer picks it up.

Make sure the agreement says you own the code. That applies to a 15-hour job just as much as a big build. For everything else the agreement should cover, see my freelance developer contract checklist.

Fixed price, capped hours or a block of hours?

There are three common ways to pay for a small job. None is always best. It mostly depends on how precisely the job can be described up front.

The math is simple: hours times rate. At an example rate of €100 per hour excluding VAT, 10 hours costs €1,000 and 50 hours costs €5,000. That's arithmetic, not a market rate, and rates vary a lot across Europe. For a Danish benchmark, see my breakdown of freelance developer hourly rates in Denmark.

With a fixed price, you're paying the developer to carry the risk. That's fair, but it also means the price usually lands at the high end of their estimate. Hourly with a cap tends to be cheapest when the job goes to plan, and you still have a ceiling.

If you want a lower price, cut the scope rather than squeezing the rate. I've written about how to do that without hurting quality in my guide on how to negotiate with a developer.

When a prepaid block of hours makes sense

A block of hours is a set number of hours you buy up front and draw down as you go. In Denmark it's called a klippekort, a clip card, much like a coffee shop punch card. It works well when:

• your app is live and small requests and bugs keep coming in
• you want the same developer every time, so you only pay the onboarding tax once
• you'd rather have a fixed budget than a new quote for every small change

For a single job, it's a poor fit. You tie up money in hours you might not need, and you don't benefit from the developer knowing your app afterwards.

Read the terms before you buy. Ask whether the hours expire and what the minimum billing unit is. Fifteen minutes, thirty minutes or a full hour per task makes a big difference across many small fixes. Ask how quickly the developer responds and whether you get a running log of hours used. Without that log, the arrangement runs purely on trust, and it doesn't have to.

A block of hours also isn't the same as a maintenance agreement or retainer. The block pays for hours. A maintenance agreement usually also covers someone monitoring the app, keeping it updated and responding within an agreed time. If your app needs to run reliably every day, that's often what you actually need.

When not to hire a freelancer for a small job

Sometimes an outside developer is the wrong choice, even for a small job:

• You already have a developer or team who knows the code. The onboarding time for someone new can eat a big part of the job.
• Your app is down right now. An outage needs someone who already has access and knows the system. If you don't have that arrangement, set it up once the fire is out.
• The problem doesn't need code. Plenty of issues in Shopify, WordPress, Webflow or an off-the-shelf CRM can be solved with a setting, an existing plugin or the vendor's support team. Ask them first.
• The job is a few hours in code the developer has never seen. You'll get more for your money by saving up requests until there's enough to justify the onboarding.
• You need someone working your hours in real time. If your team is on the US West Coast and wants live pairing all day, a developer in Europe will frustrate you, however good they are.
• The app is built on a stack the developer doesn't use daily. I work in Laravel, PHP and JavaScript (React and Next.js). If your app runs on something else, you'll get better value from someone who works in it every day.

That last one is my own line too. A small job in an unfamiliar stack quickly turns into an expensive learning exercise, and you shouldn't be paying for it.

Next steps

Run through this list before you send a small job to a developer. It takes ten minutes and often saves the first few paid hours.

Frequently asked questions

Should I pay for an estimate on a small project?+

It depends on how much digging the developer has to do. A rough estimate based on a clear brief is often free. If the estimate requires reading your code or testing an API, paying for a couple of hours of investigation is reasonable. You get a more accurate number, and the time is rarely wasted, because the same knowledge goes straight into doing the job.

What's the smallest job worth giving to a freelancer?+

My rule of thumb is that a job in an unfamiliar codebase should be big enough that onboarding isn't most of the bill. That's rarely true for a two-hour task. If the developer already knows your code, even very small jobs can be good value. If you only have one tiny thing, wait and bundle it with the next few requests.

Can I use a small project as a paid trial?+

Yes, a paid job of 10-20 hours is one of the best ways to test a working relationship before committing to something bigger. You see how the developer estimates, communicates and hands over. Pick a job that's useful on its own, so the money isn't wasted if you don't continue. Free test tasks tell you less, because they rarely look like real work.

What happens if the job turns out bigger than estimated?+

If you agreed on a cap, the developer stops before reaching it and explains why. You then have three options: approve more hours, cut something from the job, or stop and get the finished part handed over with a status note. What matters is that the decision is yours and that it's made before the hours are gone.
