FAQs

Custom business software development is the design, build, testing and running of software made for one organisation's rules, data and users. Unlike a ready product, the software follows your process and your rules. Most custom software development services also include integration with the systems you already run.

Yes. Bespoke is the British word for the same thing: software built for one organisation instead of bought off the shelf. In the UK you hire a bespoke software development company, in the US a custom software development company. The work, the risks and the questions to ask are the same.

Buy off-the-shelf when a ready product covers your process and its roadmap suits you. Build custom software when your rules, data or audit needs are what makes your business different, or when the workarounds around a ready tool already cost more than building would. In the first review we compare both on your numbers and tell you if buying is the better choice.

Cost depends on how many rules and roles the software must enforce, how many systems it connects to, how much data must move from the old system and which security and audit requirements apply. A first version that solves one clear problem costs far less than a full platform, and it shows whether the rest is worth building. We give you scope and cost after the first review, not before.

It depends on scope and on how many systems the software must connect to. FCSS, a storage market we built for FIDL, went from first version to rebuilt product in about four months. We plan in short releases, so you see working software within weeks, not only at the end.

Your data stays yours. Ownership of the code and the documentation is agreed in the contract before work starts, together with how your team or another vendor can take the system over.

Yes. Software project rescue, modernisation and enhancement all start with an audit of the live system: how it fails, how it recovers and what it does under load. Then we keep what is sound, fix what can be fixed and rebuild the rest, while the system keeps running. For a global trade technology company we cut a backlog of unconfirmed records from millions to double digits this way.

Ask any custom software development company for projects like yours with real numbers, and ask who will do the work and who leads it. Check who will own the code and the documentation, and how the team handles a failure in production. In a regulated industry, also ask what an auditor can see and who approves changes. A good partner tells you when not to build.

Poland is in the EU, so personal data is handled under the same GDPR rules as anywhere else in the EU. Working hours overlap fully with the UK and the rest of Europe and partly with the US East Coast. Neti is based in Rzeszów and works in English with clients in the UK, Germany, Switzerland, France, the US and Canada.

Yes, when they solve a real problem. We build AI features that answer from your own documents and data, cite their sources and hand uncertain cases to a person. See custom AI development.

Yes, in a separate practice for banks and fintechs. See financial software development services for payments and digital assets, and asset tokenization platform development for bonds, fund units and gold.

Before your next big client, audit or integration depends on it. A system can be live and still not be ready for what comes next: it runs every day, yet nobody can say how it recovers from a failure or what happens under twice the load. In the first review we put a number on what waiting costs you, based on your own volumes.
