Direct answer
Hiring a developer means employing a capability. Commissioning an agency means buying a project. So the first question is not which is better, but how long you will need the work and how much of it there is. A defined build with a beginning and an end, needing several skills at different moments, tends to suit an agency. A product you expect to change continuously, in a domain your own people understand deeply, tends to suit staff. Many businesses end up with a mix. This page gives you the criteria; it does not compare salaries or fees, because those depend on your market and your scope, and it does not claim that either option produces better software.
What each option really buys
An employee gives you continuity. They remember why decisions were made, they are available for small changes without a new scope conversation, and they build up knowledge of your business over time. In exchange you take on management: someone has to set priorities, review the work and cover for absence, and the person needs somewhere to grow.
An agency gives you a team assembled for a defined piece of work: typically several skills at once, such as design, back end, front end, testing and project management, and a delivery process that already exists. In exchange the relationship is shaped by a scope and an agreement, so the more your requirements shift, the more the conversation is about change control. Neither list is a verdict. They describe what you are actually paying for.
The single-developer bottleneck
The most common in-house arrangement for a smaller business is one developer. It can work well, and it carries a structural risk: all knowledge, all availability and all judgement sit in one person. Holidays, illness, a resignation or a disagreement affect the whole project. A single person also rarely covers design, infrastructure, security and testing at the same depth. None of this is a criticism of developers. It is a property of one-person teams, and if you go that way, plan for it: written documentation, code in an account you control, and a second person who can read the work.
The hybrid
The two are not exclusive. A common pattern is to commission an agency for the first build, when several skills are needed at once, and then bring maintenance or day-to-day change in-house, or the other way round: an in-house person owns the product and brings in an agency for a specific piece such as an integration, a redesign or a peak of work. The hybrid only works if the handover is designed. Ask what the agency will document, where the code and accounts will live and whether your own person can run the system without them.
What the agency must hand over
If you buy a build, the deliverable is more than a working application. Whoever inherits it, whether staff or another supplier, needs the source code, the accounts and hosting under your ownership, the credentials, documentation of how it is deployed and enough description of the business rules to change them safely. Settle this before the work starts, not at the end. What this looks like in practice is covered in who owns the code and accounts after a custom build.
When in-house wins
Staff is usually the better answer when the software is central to how you compete and will change every week; when the domain is specialised enough that months of an outsider learning it would be wasted; when you already have an engineering manager or a senior developer who can lead and review; or when you expect to keep several people building for years. In those conditions the continuity you get from employing people is the thing you actually need.
When LATYNEX is not the right fit
If you plan continuous, multi-year product development with a large internal team, an agency is probably the wrong shape of relationship for you, and we would say so at the first conversation. The same applies when you have already decided to hire and only want a supplier to fill idle capacity indefinitely. We are a good fit for a defined build, an integration, or a piece of work that a small team should deliver and hand over.
Next step
Write down, before you approach anyone: what you want built, what would count as done, whether you expect to change it continuously afterwards, and who on your side has time to manage the work. If most of those answers point to a finite project, ask an agency for a scoped proposal and compare it with what employing people would involve for you. If you are still comparing suppliers, how to choose a software development agency gives the questions to ask.

Questions
Is it cheaper to hire a developer or use an agency?+
We do not give a comparison because it depends on your market, the scope and how long you need the work. Compare the total of what each route would involve for your specific project, including management time and what happens when the work ends.
Can we start with an agency and then hire someone?+
Yes, and it is a common pattern. It works when the agency documents the system, the code and accounts are under your ownership, and your hire can read and run what was built.
What if our only developer leaves?+
Plan for it before it happens: documentation, code in an account you control and a second person who can read it. If you already have no one, an agency or another supplier can assess what exists.
Do agencies build better software than in-house teams?+
Not as a rule. Quality depends on the people and the process, not on the employment model. An in-house team with strong leadership can do excellent work, and so can an agency.
When should we not use an agency at all?+
When the product is your core, changes continuously and you have the people to lead and review its development. In that case employing the capability is usually the better fit.
