What does secure custom software cost in Switzerland in 2026?

In 2026, a professionally built custom software project in Switzerland typically costs CHF 60,000 to 150,000 for a first production version and CHF 150,000 to 400,000 or more for a full system, with security and compliance requirements adding roughly 10 to 25 percent. Uliasti is a Zürich engineering firm building for banks and SMEs; these are the numbers we actually see and quote, and here is what drives them.

The short answer, in numbers

Ranges we consider realistic for senior, Swiss-run teams in 2026:

• Discovery and prototype: CHF 15,000 to 40,000. Scope, architecture, a clickable or thin working prototype, and a real estimate for the build. This is the cheapest insurance in the industry.
• MVP or first production version: CHF 60,000 to 150,000. A focused product that real users can work with, built to production standards, not a demo.
• Full production system: CHF 150,000 to 400,000 and up. Multiple roles, several integrations, reporting, admin tooling and the operational features that never appear in the sales deck.
• Enterprise programs: beyond CHF 400,000. Multi-system integration, migrations and regulated-industry requirements set the pace here, not the amount of code.

If a quote sits far below these ranges, the difference is usually hiding in seniority, in what has been quietly excluded, or in what you will pay later.

What "secure" actually adds

Security is not a line item at the end; it is a set of practices with a real but bounded cost. On top of a competent baseline, expect:

• Threat modeling during design, so the expensive decisions are made on paper.
• Dependency and static analysis wired into the build pipeline.
• Audit trails and access controls designed in, not bolted on. This is where regulated projects spend most of their security budget.
• An external penetration test before go-live: typically CHF 10,000 to 30,000 depending on scope.
• Compliance documentation where FINMA, revDSG or client audits require it.

Together this adds roughly 10 to 25 percent to a project. Retrofitting the same properties after launch costs a multiple of that, which is why "we will add security later" is the most expensive sentence in software procurement.

Where the money actually goes

The strongest cost driver is not the number of screens. It is:

1. Integrations. Every external system your software must talk to (ERP, banking interfaces, identity providers, legacy databases) adds analysis, error handling and testing. Two similar-looking projects can differ by a factor of three on integrations alone.
2. Roles and workflows. Software for one kind of user is cheap. Software for customers, back office, compliance and administrators, each with different rights, is not.
3. Data migration. Moving and cleaning years of existing data is regularly underestimated by everyone, including us, which is why we scope it explicitly.
4. Compliance scope. Audit trails, retention rules and data-residency requirements shape the architecture itself.

Why quotes for the same brief differ by a factor of three

Three reasons, usually in combination. First, seniority: a small senior team is more expensive per hour and dramatically cheaper per outcome than a large mixed one. Second, scope honesty: the low quote often excludes security testing, documentation, project management or any contingency. Third, model: fixed-price quotes carry a risk premium; time-and-materials with a fixed discovery phase is usually the better economics for both sides.

The practical defense is to buy the discovery phase first and make the estimate part of the deliverable.

What it costs to run

Budget for the years after launch, because they are longer than the build:

• Maintenance and evolution: 15 to 20 percent of the build cost per year. Dependencies, security patches, small features, the occasional integration change.
• Hosting and monitoring: CHF 500 to 3,000 per month for typical SME-scale systems on Swiss or EU cloud infrastructure. Regulated setups run higher.

A system with no maintenance budget is a system with an expiry date.

How we keep Swiss quality at a sane price

Uliasti runs architecture, product and client work from Zürich and senior engineering from our own team in Skopje. Same standards, same employment, one team, and a blended rate meaningfully below a purely Zürich-priced project without the risks of anonymous offshoring. It is the model behind our fintech MVP work and our systems for regulated industries.

Frequently asked questions

Fixed price or time and materials?

For anything beyond a small, fully specified project: a fixed-price discovery phase followed by time and materials with a capped budget per release. Pure fixed price on vague scope means you pay a risk premium and then negotiate change requests; pure open-ended T&M without caps removes the pressure to prioritize.

What does a fintech MVP cost in Switzerland?

Typically CHF 80,000 to 150,000 when compliance-aware engineering is included from the start: audit trails, proper identity handling and Swiss or EU data residency. A fintech MVP built without those costs less at first and more overall, because it has to be partially rebuilt before any serious partner or regulator engagement.

What is the cheapest sensible way to start?

A discovery and prototype phase at CHF 15,000 to 40,000. You get validated scope, an architecture, a prototype to put in front of users and a real estimate. If you stop there, you have spent the least possible money to learn the project is not worth building, which is also a win.

Is nearshore development safe for regulated Swiss data?

Yes, with the right structure: the data stays in Swiss or EU infrastructure, access is role-based and logged, and the nearshore engineers are employees of the firm you contract, not subcontractors of subcontractors. What is not safe is a chain of anonymous outsourcing where nobody you have met writes the code.
