You are about to outsource software development for the first time, or after a first attempt that didn't go well. The internet is full of advice about models and rates, yet most outsourcing projects that fail don't fail in the code. They fail earlier: in a contract that didn't match the work, or in a recruitment process that put the wrong people on the project.
This guide covers software development outsourcing from start to finish: the models, how the main regions compare, how a good provider actually finds and vets engineers, what to put in the contract, the main risks and how to choose a vendor. For how ITDS works, see our page on nearshore software development from Poland and Portugal.

What is software development outsourcing?
Software development outsourcing means using an external company to build, extend or maintain your software. That can mean a few engineers joining your team, a whole team working on your product, or a provider delivering a defined project.
Companies outsource for access to skills they can't hire quickly, for speed and for flexibility. The shortage is real: according to Eurostat, more than half of EU companies that tried to hire ICT specialists in 2023 struggled to fill those roles. Cost savings can follow, but they are the proof that outsourcing works, not the reason to start.
| Most outsourcing fails at the contract stage and the recruitment stage, long before anyone writes a line of code. |
Software development outsourcing models
| Model | What you get | Who directs the work | Best when |
|---|---|---|---|
| Staff augmentation | Individual engineers who join your team | You | You have a strong tech lead and clear skills gaps |
| Dedicated team | A complete team, often with its own lead | The team lead, against your priorities | You need a whole capability for a year or more |
| Project outsourcing | A defined scope, often at a fixed price | The provider | The scope is stable and the finish line is clear |
Many companies combine the models over time, for example starting with two augmented engineers and growing them into a dedicated team. Our guides to providing IT specialists, building IT teams and project development explain each one.
Software development outsourcing regions compared
| Region | Overlap with UK and EU teams | Overlap with US East Coast | Typical strength |
|---|---|---|---|
| Your own country (onshore) | Full | Full | Same culture and law, smallest talent pool |
| Portugal and Poland | Full or almost full | About 2 to 4 hours | Senior depth, EU law and data protection |
| Latin America | Little | Most of the day | Real-time collaboration with US teams |
| South and Southeast Asia | Partial or little | Little or none | Scale and low headline rates |
For European companies, Portugal and Poland usually offer the best balance of shared hours, senior talent and legal certainty. For US companies, the choice is between more live overlap in Latin America and deeper senior talent under EU law in Europe.
The IT outsourcing recruitment process, step by step
This is the part most guides skip, and the part that decides whether your project works. When you outsource, you are really buying a provider's ability to find, vet and keep the right engineers. Here is how a good process looks, using ours as the example.
- Role briefing. A call to understand the work, the stack, the seniority, the team and how you work. A good provider asks more questions here than you expect.
- Sourcing. Searching the provider's own network and the wider market. At ITDS, that means our own network of engineers in Poland and Portugal, plus a targeted search for each role.
- Recruiter screening. Experience, motivation, availability, contract preferences and communication.
- Technical interview. Run by a specialist in the stack, not by a generalist recruiter.
- Language check. English, plus any other language the role needs, such as French.
- Shortlist. Only candidates who pass every stage reach you. At ITDS, roughly one in five candidates passes our vetting, and for common profiles the first candidates often reach clients within about 48 hours.
- Your interviews. You meet the shortlist and choose.
- Offer and contract. The provider agrees terms with the engineer and with you.
- Onboarding. The engineer joins your tools and rituals. On average, our clients go from starting a search to an integrated engineer in about 20 days.
- Ongoing care. Regular check-ins with the engineer and with you, and fast replacement if something doesn't work.
When you compare providers, ask them to walk you through their own version of this process, with names and numbers. A provider that can't describe how it vets engineers can't guarantee who you will get.

Contracts and pricing
Most outsourcing is priced in one of two ways. Time and materials (T&M) means you pay for the hours or days worked, which suits work that will change as you learn. Fixed price means you pay an agreed amount for an agreed scope, which suits stable, well-defined projects. Our guide to optimising IT project costs without compromising quality covers the trade-offs in more detail.
Whatever the model, make sure the contract covers:
- IP ownership. Everything the engineers create belongs to you.
- Replacement terms. What happens, and how fast, if an engineer leaves or doesn't fit.
- Notice periods and minimum term. For both sides.
- What the rate includes. Recruitment, replacement, account management and any tools.
- Data protection. A data processing agreement if engineers can access personal data.
Rates vary widely with stack, seniority, country and contract, so ask for a written rate card and confirm current rates before you budget. This section is general information, not legal advice, so have your contract reviewed by your own counsel.
Risks of software development outsourcing and how to reduce them
- The wrong people. Reduce it by interviewing the shortlist yourself and asking how candidates were vetted.
- A contract that doesn't match the work. Avoid fixed prices for work that will change.
- Hidden management cost. Plan who on your side will lead and review the work.
- Turnover. Ask how long engineers usually stay, and what replacement cover you get.
- Two teams instead of one. Give external engineers the same tools, rituals and access as your own team.
- Data and security. Prefer engineers working inside the EU, and agree access rules up front.
Choosing a software development outsourcing vendor
Ask every vendor the same questions and score the evidence, not the pitch. Our 12-point scorecard for shortlisting IT outsourcing companies gives you the questions, a scoring method and a downloadable Excel file. Shortlist three vendors, then call two references for each finalist.
Where ITDS fits
ITDS is an IT staffing and nearshore company with teams in Portugal and Poland, part of House of HR. We deliver staff augmentation, dedicated teams and projects, so we can recommend the model that fits rather than the one we sell. Roughly one in five candidates passes our vetting, and our clients reach an integrated engineer in about 20 days on average.
Software development outsourcing: FAQ
It is how a provider finds and vets engineers for your project: role briefing, sourcing, recruiter screening, a technical interview with a specialist, a language check, a shortlist, your own interviews, the offer and contract, onboarding and ongoing care. At ITDS, it takes about 20 days on average from starting a search to an integrated engineer.
You agree a model with a provider, such as staff augmentation, a dedicated team or a fixed-price project. The provider finds and vets engineers, you approve them, and they work on your software under the terms of the contract.
For European companies, Portugal and Poland offer shared working hours, senior engineers and EU law. US companies often weigh Latin America's live overlap against Eastern Europe's senior depth.
It depends on the model, stack, seniority and country. Ask each provider for a written rate card, compare total cost rather than hourly rates, and confirm current rates before you budget.
IP ownership, replacement terms, notice periods and minimum term, what the rate includes and, where personal data is involved, a data processing agreement. Have your own counsel review it.
