In-house vs outsourced software development costs

Key takeaways

In-house vs outsourced software development depends on how long you need the team. Three UK developers on £50,000 cost about £183,000 a year with tools, before recruitment. A managed offshore team of similar size costs an indicative £20–£40 per developer hour. Keep product ownership in-house whichever route you choose.

• In-house: about £183,000 a year for three £50,000 developers with tools.
• Outsourced: an indicative £20–£40 per developer hour offshore.
• In-house: best for a long-term core product with constant change.
• Outsourced: best for defined builds and fluctuating capacity.

What does an in-house development team cost?

A developer on £50,000 costs about £58,063 a year in employment costs using 2026/27 rates. Add about £3,000 for equipment, software and cloud tools, and three developers cost about £183,000 a year. Recruitment is significant for technical roles, and you still need product management, testing and hosting.

What does outsourced development cost?

As indicative ranges, UK development agencies often charge day rates in the hundreds of pounds per developer, while managed offshore teams commonly charge about £20–£40 per developer hour depending on seniority. A three-person offshore team working full time costs roughly £104,000–£209,000 a year at those rates, so at the senior end it can cost as much as in-house. The bigger gains are no recruitment and the ability to scale down after a build. Always compare quotes on the same scope.

When should software development stay in-house?

When the software is your product, changes every week, and depends on deep knowledge of your customers and data. A long-term in-house team builds that knowledge and moves fastest on it. Many software businesses keep a core team in-house and add outsourced capacity.

When is outsourcing development better?

When you need a defined build, such as an internal tool, a customer portal or an integration, rather than a permanent team. Outsourcing also suits variable capacity: adding developers for a phase and scaling down after launch, without recruitment or redundancy.

How do you keep control of outsourced development?

Keep product ownership in-house: someone who decides priorities, accepts work and talks to users. Own the code repository, cloud accounts and domain, and write intellectual property transfer into the contract. Agree how work is estimated, reviewed and tested before it starts.

• A named product owner in your business.
• Code, cloud and domain accounts in your name.
• IP assigned to you in the contract.
• Regular demos of working software.
• Testing and code review built into the process.

What are the hidden costs on each side?

In-house, the hidden costs are recruitment, idle time between projects and the risk of one developer holding all the knowledge. Outsourced, they are your product owner's time, communication overhead across time zones, and rework if requirements are vague. Clear, written requirements reduce both.

How should an outsourced build be scoped?

Start with the problem and the users, not a feature list. Describe the processes the software must support, the systems it must connect to, and what a successful first release looks like. Ask providers to propose a first phase that delivers something usable in weeks, then plan later phases once it is in use.

• custom software roadmap

What does this look like in practice?

A pattern we see in UK brokerages and professional services firms: a custom CRM integration is needed, but hiring a developer for one project makes little sense. A defined outsourced build with an in-house product owner delivers it, and a small support retainer covers changes afterwards.
