How to Outsource Software Development: A Buyer's Guide
To outsource software development, write down the outcome you need, choose an engagement model that matches how well the scope is defined, and check each vendor on code ownership, access to engineers, security, references and change pricing. Start with a small paid piece of work before you commit the full budget. Put ownership, acceptance, change control and exit terms in the contract.

Why do companies outsource software development?
Companies outsource software development mainly to reach skills they cannot hire quickly, and second to control cost. Deloitte's Global Outsourcing Survey 2024 (report PDF dated December 2024) drew on "more than 500 global business and technology leaders". Its most cited driver for outsourcing was "Improved access to talent" at 42%. "Spend optimization" came third at 34%.
The same report shows the cost motive fading. The share of respondents naming cost reduction as a primary driver fell from 70% in 2020 to 34% in 2024. In the 2024 survey, 72% of organizations outsourced application and software development.
Hiring conditions explain the talent motive. The US Bureau of Labor Statistics, on a page last modified August 27, 2026, projects employment of software developers, quality assurance analysts and testers "to grow 10 percent from 2025 to 2035", with "About 106,100 openings" each year. The median annual wage for software developers was $135,980 in May 2025.
Two cautions apply. Deloitte's respondents are large organizations, and Deloitte sells sourcing advice. A lower hourly rate also does not guarantee a lower cost. Accelerance reported on November 24, 2025 senior developer rates of $31–$41 per hour in Asia, $60–$75 in Latin America and $64–$76 in Europe, based on its survey of 60 software development partners. In the same article, Olivier Poulard, a managing director at Accelerance, says, "rates are important, but they are not the same as costs." Accelerance sells outsourcing advisory services.
When does outsourcing make sense?
Outsourcing makes sense when the work can be described in writing, when you need a skill for a limited period, or when you must ship before you could recruit a team. It also needs one person on your side with the authority and the time to make decisions.
It is a poor fit in three situations:
- Nobody on your side can own the product. A vendor builds what you specify. Deciding what the business needs stays with you.
- The work needs constant side-by-side sessions. An in-house team suits that better.
- The data may not leave your environment, and the vendor cannot work inside it.
Keep the option to bring work back. In the Deloitte survey, 70% of executives had "insourced scope that was previously with a third-party over the past five years". The reason cited most often, by 68%, was "Better control over service quality and performance". Exit terms in the contract protect that option.
Which engagement model should you choose?
Choose by how well you can define the result and by who will manage the work. Four models cover most engagements.
| Model | What you buy | Who manages the work | How it is priced | Fits when |
|---|---|---|---|---|
| Fixed-price project | A defined result | The vendor | A set price, paid by milestone | The scope can be written down and will hold |
| Time-and-materials project | A result whose details will evolve | The vendor, following your priorities | Time worked, often with a cap | You know the goal and expect the details to change |
| Dedicated team | A standing team for one product | Shared | Per team, per month | The roadmap is long and priorities shift |
| Staff augmentation | Individual engineers | You | Per person, per hour or month | You run an engineering team and need capacity or a skill |
Large buyers have moved toward models that price results. Deloitte found that 67% of executives reported adoption of "managed or operate services (up from 45% two years ago)", against 29% for the "legacy staff-augmentation model". The report concludes that "organizations are interested in buying capabilities and outcomes, and not hours."
A fixed price moves risk to the vendor only while the scope stays fixed. Once the scope shifts, every change becomes a negotiation.
How do you choose a software development company?
Choose on evidence you can check: who will own the code, who will do the work, how the vendor protects your systems, what it has shipped and how it prices change. Ask for each answer in writing. The same checks apply to a custom software development company of any size.
| Check | What to ask | What good evidence looks like |
|---|---|---|
| Code ownership | Who owns the code, and which vendor-owned or third-party components are included | A written assignment of intellectual property; a repository in your account from the first commit |
| Access to engineers | Who will write the code, and whether you can speak to them | A call with the named engineers; a shared channel during the work |
| Security practices | How access is granted and revoked, and where credentials and production data are kept | Individual accounts with multi-factor authentication; a written offboarding procedure |
| References and live work | Which live products the vendor built, and which parts of them | Products you can open, with the vendor's role stated; a client you can call |
| How changes are priced | How a change is estimated, who approves it and at what rate | A written change process, with rates agreed before the first change |
| Quality process | Who reviews code, which tests run automatically, how AI-generated code is checked | Review on every change; tests in a CI pipeline; a staging environment you can open |
| Working hours | Which hours overlap with yours | An overlap window, stated in your time zone, in the agreement |
| Exit | What you receive if the contract ends | Repository, documentation, credentials and deployment scripts |
Why does code ownership need a written assignment?
Paying for software does not by itself make you the copyright owner. In the United States, Copyright Office Circular 30 (revised August 2024) explains that a commissioned work is a "work made for hire" only if it falls within nine listed categories and the parties agree so in a signed written instrument. The categories include a translation and a compilation. Custom software does not obviously fit any of them, which is why contracts add an explicit assignment of copyright.
The United Kingdom starts from the same position. Intellectual Property Office guidance published August 19, 2014 states: "When you ask or commission another person or organisation to create a copyright work for you, the first legal owner of copyright is the person or organisation that created the work and not you the commissioner, unless you otherwise agree it in writing." Have counsel confirm the wording for your jurisdiction.
What should you ask about security?
Ask how the vendor builds securely and how it controls access to your systems. Two public documents give buyers the vocabulary. NIST's Secure Software Development Framework, published February 2022, says "software purchasers and consumers can also use it to foster communications with suppliers in acquisition processes and other management activities". CISA and the FBI published the Secure by Demand Guide in August 2024, a set of questions for software buyers to put to suppliers.
A joint advisory dated May 11, 2022 from CISA and partner cybersecurity agencies advises customers of managed service providers (MSPs) that "Contracts should also require MFA to be enforced on all MSP accounts used to access customer environments". It also says contracts should state how and when the provider reports an incident. Both terms suit any vendor with access to production.
Why ask about AI-generated code?
Ask because your vendor almost certainly uses AI coding tools, and the output needs review. In the 2025 Stack Overflow Developer Survey, "84% of respondents are using or planning to use AI tools in their development process". Veracode reported on July 28, 2026 that "The average security pass rate across models is 56%" on its security test tasks. A vendor should be able to say who reviews AI-written code and which tests it must pass.
What should the contract settle?
The contract should settle eight points before work starts. Treat the list as a starting point for your lawyer.
- Intellectual property. Assignment of all work product on payment, and a list of vendor-owned and open-source components.
- Repository and accounts. Code, cloud accounts and domains held in your company's name.
- Acceptance. Written criteria for each milestone and a set period to accept or reject.
- Change control. How a change is requested, estimated, approved and billed.
- Confidentiality and data protection. For personal data covered by UK law, ICO guidance quotes the UK GDPR requirement that "Processing by a processor shall be governed by a contract or other legal act". The ICO marks this guidance as under review.
- Security duties. Multi-factor authentication, removal of access at offboarding and incident notice periods.
- Warranty. A period after delivery in which defects are fixed without charge.
- Termination and handover. Notice period, final deliverables and help with the transition.
Contract terms are a common weak point. In the Deloitte survey, 38% of respondents named "Poor contract and contract change management" among their outsourcing challenges.
What are the warning signs?
The warning signs are mostly refusals: to show people, code, past work or a process. Treat any of these as a reason to pause.
- You cannot speak to the engineers who would do the work.
- The code would stay in the vendor's repository until final payment.
- A fixed price arrives without questions about an unclear scope.
- Past work cannot be opened, or the vendor's role in it is vague.
- Testing is described as something done by hand at the end.
- Engineers would share accounts, or production data would sit on laptops.
- The vendor cannot say how AI-generated code is reviewed.
- The rate sits far below published ranges for the region, with no explanation.
How do you hire offshore software developers and run the work?
Hire offshore developers with the same checks as any vendor, then add written rules for time zones and communication. Six steps keep the risk low.
- Write the outcome. One page: what the software must do, for whom, and how you will know it works.
- Choose the model. Use the table above.
- Shortlist on evidence. Put each vendor through the checklist.
- Buy a small first piece. A discovery phase, an audit or one feature shows how the team estimates, communicates and delivers.
- Run the work in the open. Your repository, a shared board, regular demos of working software, and decisions recorded in writing.
- Review after the first milestone. Compare what was promised with what was delivered.
For offshore teams, fix an overlap window in your time zone, default to written specifications, and agree who responds when production fails outside the window.
Your own management effort decides much of the outcome. Deloitte's report states that "Internal management capabilities are a common cause of outsourcing challenges." The challenge cited most often, by 55%, was "Lack of benefit realization tracking & reporting".
Key takeaways
- Access to talent was the top outsourcing driver in Deloitte's 2024 survey at 42%. Cost reduction as a primary driver fell from 70% in 2020 to 34%.
- Match the model to the scope: fixed price for a stable scope, time and materials or a dedicated team for a changing one, staff augmentation when you manage the engineers.
- In the US and the UK, commissioned code does not automatically belong to the buyer. Get a written assignment.
- Ask how access is controlled, how changes are priced and how AI-generated code is reviewed.
- A small paid first piece tells you more than a proposal does.
Frequently asked questions
How do you outsource software development?
Write down the outcome, choose an engagement model, shortlist vendors on live work similar to yours, and buy a small paid first piece such as a discovery phase. Then sign a contract that covers ownership, acceptance, change control, security and exit, and run the work in a repository you own.
How do you choose a custom software development company?
Check eight things in writing: code ownership, access to the engineers, security practices, references and live work, change pricing, the quality process, overlapping working hours and what you receive on exit.
Why outsource software development?
The main reason is access to skills. In Deloitte's 2024 survey, 42% of respondents named improved access to talent as a primary driver, ahead of spend optimization at 34%.
Who owns the code when you outsource development?
Whoever the contract says. Without a written assignment, the creator usually holds the copyright. US Copyright Office Circular 30 limits commissioned "works made for hire" to nine categories, and UK guidance says the creator is the first owner "unless you otherwise agree it in writing".
How much does it cost to outsource software development?
Cost depends on rate, hours, your own management time and rework. For rates, Accelerance reported senior developer ranges of $31–$41 per hour in Asia, $60–$75 in Latin America and $64–$76 in Europe on November 24, 2025. These are one advisory firm's survey figures.
