# In-house, agency or dedicated team: how to decide who builds your software

Each model suits a different situation. The right one depends on how long the work will last, how much control you need and how fast you have to start.

## Key takeaways

- In-house hiring gives the most control and the longest ramp-up, and suits work that will continue for years.
- An agency suits a defined project with a clear end, and you pay for the outcome rather than the people.
- A dedicated team gives you an extension of your own engineering capacity, without the delay of hiring.
- Whichever you choose, check who owns the code and what happens if the arrangement ends.

## What are the three options?

- **In-house developers** — Employees on your payroll, working inside your company.
- **Agency or project supplier** — An outside company that delivers a defined piece of work for an agreed scope.
- **Dedicated team** — An outside team that works only for you, on your priorities, as an extension of your own.

## When does in-house hiring make sense?

Hire when the software is central to your business and the work will continue for years. You get full control, deep knowledge of the product and no dependence on a supplier. The costs are time and risk: recruiting takes months, a bad hire is expensive, and you need enough work and management to keep people productive.

## When does an agency make sense?

Use an agency when the project has a clear scope and an end date, such as a new website, a one-off integration or a first version. You buy a result, and the supplier manages the people. The trade-off is that your product knowledge sits partly outside your company, and changing direction mid-project usually means renegotiating scope.

## When does a dedicated team make sense?

A dedicated team fits ongoing work where you want control of priorities but cannot wait to hire, or where demand will rise and fall. You direct the work day to day while the supplier handles recruitment, employment and replacement. See our guide to [hiring a dedicated development team](https://www.cognivise.co.uk/blog/hiring-a-dedicated-development-team) for how to set one up.

## How do you compare them?

| | In-house | Agency | Dedicated team |
|---|---|---|---|
| Control of priorities | Full | Through the agreed scope | High |
| Time to start | Slowest | Fast | Fast |
| Best for | Long-term core product | Defined project | Ongoing work, uneven demand |
| Main risk | Hiring and retention | Scope disputes | Needs clear direction from you |

## What questions settle it?

1. Will this work last more than a year, or is there an end date?
2. Do you have someone who can direct engineers every day?
3. How soon must work start?
4. How much of the product knowledge must stay inside the company?
5. Can you afford the delay and risk of recruiting?

Many companies use a mix: a small in-house core with outside capacity around it. The article on [staff augmentation vs outsourcing](https://www.cognivise.co.uk/blog/staff-augmentation-vs-outsourcing) explains the supplier models in more detail.

## What should you check whichever you choose?

- the code and accounts are yours
- documentation is kept up to date
- there is a defined way to end or change the arrangement
- you know who is accountable when something fails
