Buyer's guide
Freelancer vs. agency vs. offshore vs. in-house team: who should build your software?
By Nick McCandless, founder of EltherionLast updated
The short answer
Hire a freelancer for a small, well-defined project you can manage yourself. Hire an agency when you need a complete team (design, engineering, testing and project management) to deliver a defined product without building a department, and consider an offshore team when budget is the main constraint and you have strong technical management in-house. Build an in-house team when software is your core business and you will keep developing it for years.
Side-by-side comparison
| Criterion | Freelancer | Agency | Offshore team | In-house team |
|---|---|---|---|---|
| Cost | FreelancerLowest for small scopes. You pay one person's rate and do the project management yourself. | AgencyTypical US agencies charge $120k to $300k for a first customer-facing web app. Eltherion projects start as low as $1,000. | Offshore teamOften cheaper per hour than US agencies. Low quotes sometimes exclude scope, so compare what is included. | In-house teamThe median U.S. software developer wage was $135,980 in May 2025. Benefits add more, and a product usually needs several roles. |
| Time to launch | FreelancerQuick to start. Slower for large scopes, because one person has limited capacity. | AgencyStarts in weeks. In our experience a first version takes three to six months. | Offshore teamQuick to start and staff up. Time zone gaps can slow feedback loops. | In-house teamSlowest to start, because recruiting comes before building. |
| Flexibility | FreelancerVery flexible, but limited to one person's skills. | AgencyBroad skills on demand. Scope changes go through the contract. | Offshore teamCan add people quickly. Communication overhead grows with team size. | In-house teamMaximum control and business context, but fixed capacity. |
| Ownership and IP | FreelancerThe freelancer generally owns the copyright unless it is assigned to you in a signed, written agreement. | AgencySame rule. Also ask how any reusable components or libraries the agency brings are licensed to you. | Offshore teamSame rule, and enforcing a contract across borders is harder. | In-house teamWork an employee creates within the scope of the job is a work made for hire owned by the employer. |
| Maintenance | FreelancerDepends on that person staying available. | AgencyUsually a support or maintenance retainer after launch. | Offshore teamUsually a retainer. Plan the handover if you ever bring it in-house. | In-house teamYour team maintains it, and payroll continues whether there is a project or not. |
| Risk | FreelancerSingle point of failure. Treating a contractor like an employee can also create tax classification issues. | AgencyHigher price, and quality varies widely between firms. | Offshore teamQuality, communication and data-handling risk, unless you manage closely. | In-house teamHiring mistakes are expensive, and so is losing a key engineer. |
| Best fit | FreelancerSmall, well-defined tasks, or adding one skill to an existing team. | AgencyA defined product or system that needs a full team for months, not years. | Offshore teamBudget-led projects with a strong in-house technical lead. | In-house teamSoftware that is your core product, developed continuously for years. |
01
When a freelancer is the right choice
A good freelancer is the most cost-effective option for a clearly defined piece of work: a website, a single integration, a prototype, or one specialist skill your team is missing. You get direct access to the person doing the work with no agency overhead.
The trade-off is that you become the project manager, and everything depends on one person. Two legal points matter. Under U.S. copyright law, a contractor generally owns what they create unless rights are transferred, and the U.S. Copyright Office explains that commissioned work only counts as work made for hire in nine narrow categories with a signed written agreement. A transfer of copyright must be in writing and signed. And if you control how, when and where a contractor works like an employee, the IRS classification rules may treat them as one.
Good signs
- The scope fits on a page and is unlikely to change much.
- You or someone on your team can review the work technically.
- The project is weeks, not months.
- You have a plan if that person becomes unavailable.
02
When an agency is the right choice
An agency makes sense when you need a whole team, including design, engineering, testing and project management, to deliver a defined product, and you do not want to build a software department to do it. You buy coordinated delivery and accountability for an outcome, not just hours.
Agencies cost more per hour than freelancers or offshore teams, so the question is whether that buys you less risk and less of your own time. Ask exactly who will work on your project, see work similar to yours, and insist that code lives in a repository you own from the first day.
Good signs
- The project needs several disciplines working together.
- You want one accountable party for scope, budget and timeline.
- You do not have a technical leader in-house to manage a team.
- The work is a defined build, not an open-ended product roadmap.
03
When an offshore team is the right choice
Offshore teams can stretch a budget a long way, and many are highly skilled. They work best when you already have a strong technical lead who can write precise specifications, review code and manage the team day to day.
Where projects go wrong is in the gaps: unclear requirements across a language or time zone difference, quotes that look cheaper because they leave scope out, and slower feedback. In our own calculator we model an offshore agency at 0.45 times and a mixed onshore and offshore team at 0.7 times the senior US cost. That is our planning assumption, not a market survey, and the savings only hold if rework stays low.
Good signs
- Budget is the main constraint.
- You have an experienced technical lead with time to manage the team.
- Requirements are detailed and stable.
- You have several hours of working-day overlap, or work that tolerates delay.
04
When an in-house team is the right choice
If software is your product, and you will keep improving it for years, you will usually want the core team in-house. Employees build deep context, and under U.S. law, work an employee creates within the scope of their job is a work made for hire owned by the employer, according to the Copyright Office.
It is also the largest fixed commitment. The Bureau of Labor Statistics puts the median annual wage for software developers at $135,980 in May 2025. Benefits add more: across private industry, they made up 30.0% of employer compensation costs in June 2026. If that average held, a median-paid developer would cost about $194,000 a year in wages and benefits, before recruiting, equipment, software and management time. A first product usually needs more than one person.
Good signs
- Software is the product you sell, or the core of how you deliver it.
- You have years of roadmap, not months.
- You can hire and lead engineers, or are ready to hire someone who can.
- You can carry the payroll between major projects.
Mixing models is normal
These options are not exclusive. A common pattern is an agency building the first version while you hire a small in-house team, then a handover. Another is an in-house lead who brings in freelancers or an agency for specialist work such as AI, mobile or a migration. What matters is that someone on your side owns the product and the code at every stage.
Questions to ask whoever you hire
These apply to freelancers, agencies and offshore teams alike:
- Who exactly will work on this, and how senior are they?
- Will the code live in a repository we own from day one?
- Does the contract assign copyright to us in writing, and how are any reused components licensed?
- What is included in the price, and what is explicitly excluded?
- How will we see progress, and how often?
- What does maintenance cost after launch?
- What happens to documentation and access if we part ways?
Honest advice
When not to hire a firm like Eltherion
We are a senior US team, which is the right fit for some projects and the wrong one for many. Look elsewhere if:
- The work is small and well defined. A good freelancer will be faster and cheaper.
- You already have an engineering team and need one extra skill. Hire a specialist contractor.
- You need a full-time team embedded in your company for years, and you are ready to hire and manage one.
- Software is your core product and you plan to develop it for years. Build the team in-house; a firm can help you start, but should not be your permanent engineering department.
Decision checklist
Use this to decide, then to vet whoever you choose.
- 01Write a one-page scope: users, core features, integrations, deadline.
- 02Decide who on your side manages the work day to day, and how many hours a week they have.
- 03Estimate how long you will keep developing the software: months or years.
- 04Compare three-year cost, not just the build quote.
- 05Get the copyright assignment in writing before any code is written.
- 06Make sure code lives in a repository you own from the first day.
- 07Ask who specifically will do the work, and talk to them.
- 08Check working-hour overlap and response times.
- 09Agree on documentation and handover terms up front.
