Custom software services in Switzerland are the design, development and long-term maintenance of software built for one company’s workflows, data and legal obligations, instead of licensing a generic product. FEEL IT Services builds this kind of software for Swiss SMEs and enterprises in finance, insurance, pharma, manufacturing, logistics and MedTech, with compliance with the revised Swiss Federal Act on Data Protection (revFADP, in German nDSG) and the EU GDPR designed in from the first sprint.

This guide is for CTOs, IT managers and operations leads at Swiss companies who are deciding whether to build or buy. It covers when custom software pays off, which Swiss rules it has to meet, what a project with FEEL IT looks like step by step, and what drives cost.

Key takeaways

• Custom software makes sense when off-the-shelf tools force manual workarounds, create compliance gaps or lock you into a vendor’s roadmap.
• Since 1 September 2023, the revFADP requires privacy by design and by default, and allows fines of up to CHF 250,000 against responsible individuals.
• Swiss software usually has to work in at least two of the country’s four national languages.
• FEEL IT runs projects in two-week sprints with one dedicated project manager, and the client owns 100% of the source code.

When does custom software make sense for a Swiss company?

Off-the-shelf software is built for the widest possible market. That works for standard functions like email or basic accounting. It stops working when your competitive advantage sits in a process the product was never designed for, or when Swiss regulation asks for controls the vendor does not offer.

Custom software development is usually the better choice when at least two of these apply:

• Your team runs spreadsheet workarounds to bridge gaps between tools that don’t talk to each other.
• You pay for features nobody uses while the ones you need sit on a vendor roadmap with no date.
• You can’t prove where personal data lives or who accessed it, which becomes a problem under the revFADP and GDPR.
• Your users work in German, French and Italian and the current tool only half-supports that.
• A legacy system holds critical data and nobody wants to touch it, but it blocks every new initiative.
• Licence costs rise with every new user or module, and switching vendors would mean losing your data model.

See examples of how FEEL IT has solved these problems in the FEEL IT project portfolio, from enterprise integrations to bespoke SaaS platforms in the DACH region.

Which Swiss compliance requirements must custom software meet?

The main law is the revised Federal Act on Data Protection (FADP), which entered into force on 1 September 2023 and replaced the 1992 version. It applies to every company processing personal data of people in Switzerland. Companies that also serve EU customers must meet the GDPR in parallel. The table below shows what these rules mean in practice for software architecture.

Requirement	What it means for the software	How FEEL IT builds it in
Privacy by design and by default (Art. 7 FADP)	The most privacy-friendly settings must be active out of the box; data collection is limited to what’s needed.	Data minimisation and default settings defined in the discovery phase, before any code is written.
Data breach notification (Art. 24 FADP)	Breaches that pose a high risk must be reported to the Federal Data Protection and Information Commissioner (FDPIC) as soon as possible.	Audit logs, access monitoring and alerting so incidents can be detected and documented quickly.
Records of processing activities (Art. 12 FADP)	Companies must document what personal data they process and why. Firms with fewer than 250 employees are exempt unless the processing is high-risk.	Data maps and processing documentation delivered with the software.
Data protection impact assessment (Art. 22 FADP)	Required before high-risk processing, such as large-scale sensitive data or profiling.	Risk assessment support during architecture design.
Cross-border data disclosure (Art. 16 FADP)	Data may go abroad only to countries with adequate protection (such as EU/EEA states) or under safeguards like standard contractual clauses.	Hosting choice, including Swiss data centres, agreed per project and documented.
Sector rules (e.g. FINMA for banks and insurers)	Outsourcing of critical functions must meet supervisory requirements on control, audit and data access.	Architecture and contracts aligned with the client’s compliance team from day one.

Penalties under the revFADP target individuals, not just companies: intentional violations of certain duties can lead to fines of up to CHF 250,000 (FDPIC). That makes compliance a management issue, not only an IT one. Switzerland also holds an EU adequacy decision, reconfirmed by the European Commission in January 2024, so well-built Swiss systems can exchange personal data with the EU without extra paperwork.

Custom software vs off-the-shelf: how do they compare?

Criterion	Off-the-shelf software	Custom software by FEEL IT
Fit with your processes	You adapt your processes to the tool	The software follows your processes
revFADP / GDPR control	Depends on the vendor’s settings and hosting	Designed in; you choose hosting location
Languages	Often limited to German or English	DE / FR / IT / EN built in where needed
Code ownership	Vendor owns it; you rent access	Client owns 100% of the source code
Integration with ERP, CRM, banking	Limited to available connectors	Custom APIs for any system
Upfront cost	Low	Higher
Long-term cost	Licence fees grow with users and modules	No per-user licence; maintenance under SLA
Time to start	Days to weeks	Weeks to months, with working software every two weeks

Language support matters more in Switzerland than in most markets. According to the Federal Statistical Office (FSO), about 62% of the population names German as a main language, about 23% French and about 8% Italian. A tool used across Zurich, Geneva and Lugano needs all three to work properly.

What do FEEL IT’s custom software services in Switzerland include?

FEEL IT’s cross-functional teams cover the full lifecycle: business analysis, UX design, backend architecture, frontend development, QA testing and DevOps. The core services are:

• Web and mobile applications with multilingual interfaces and Swiss hosting options.
• Process automation and workflow engines that remove manual, repetitive work.
• API development and system integration connecting ERP, CRM, banking systems and third-party services into one data environment.
• Data platforms and dashboards giving management real-time views of operations, finance and KPIs.
• SaaS product development, from validated MVP to market launch in Switzerland and Europe.
• Legacy system modernisation using careful data migration and parallel running, so operations continue during the switch.

How does a custom software project with FEEL IT run?

FEEL IT uses an agile delivery model adapted to what Swiss clients expect: predictable timelines, clear budgets and full visibility. A typical project runs in six steps.

1. Step 1: Discovery. FEEL IT maps your business goals, current systems, users and compliance requirements. The output is a scope, a technical concept and a cost estimate.
2. Step 2: Architecture and UX. Data model, hosting, integrations and privacy settings are fixed. Users test clickable prototypes before development starts.
3. Step 3: Development in two-week sprints. Each sprint ends with a demo of working software, so decisions are based on real progress rather than documents.
4. Step 4: Testing and compliance checks. QA, security testing and a review of data protection settings before go-live.
5. Step 5: Launch and migration. Data is migrated and, where needed, old and new systems run in parallel until the switch is safe.
6. Step 6: Support and maintenance. SLA-backed support keeps the software secure, performant and up to date.

Throughout the project, one dedicated project manager is your single point of contact for scope, timelines and escalations. Clients choose between fixed-scope and time-and-materials contracts depending on their risk profile. Read more about the FEEL IT delivery approach and technology selection.

Which industries does FEEL IT serve in Switzerland?

FEEL IT builds custom software for finance and banking, insurance, pharmaceuticals, MedTech, manufacturing, logistics and professional services. Regulated sectors benefit most, because their requirements, such as FINMA rules for financial institutions or strict data handling in MedTech, are rarely covered fully by standard software.

How much do custom software services in Switzerland cost?

Cost depends on four main factors: scope and number of features, the number and complexity of integrations, team size, and timeline. A focused automation tool and a full enterprise platform sit at very different price points, which is why FEEL IT gives a fixed estimate only after a free discovery consultation. In that session, requirements, expected ROI and milestones are defined in writing before any commitment.

When comparing offers, look beyond the day rate. Check who owns the code, what the SLA covers after launch, and whether compliance work is included or billed separately.

Frequently asked questions about custom software in Switzerland

What are custom software services in Switzerland?

Custom software services in Switzerland are the development of software built for one company’s specific workflows, data and Swiss legal requirements, rather than licensing a standard product. The client usually owns the source code. FEEL IT delivers these services with revFADP and GDPR compliance built into the architecture from the start.

Does custom software have to be hosted in Switzerland?

No. The revFADP does not require Swiss data residency. Personal data can be stored in countries with adequate protection, such as EU and EEA states, or elsewhere with safeguards like standard contractual clauses. Some sectors and clients still require Swiss hosting by contract, and FEEL IT supports Swiss data centre options.

Who owns the code of software built by FEEL IT?

The client owns 100% of the source code from day one. This removes vendor lock-in: you can host, extend or hand the software to another team at any time, without depending on a third party’s pricing or product roadmap.

Is FEEL IT’s software compliant with Swiss data protection law?

Yes. FEEL IT designs software for compliance with the revised Swiss Federal Act on Data Protection (revFADP/nDSG) and the GDPR. Privacy by default, access controls, audit logging and documentation of data processing are defined in the discovery phase and built in from the first sprint.

Can custom software integrate with our existing ERP, CRM or banking systems?

Yes. System integration is one of FEEL IT’s core services. Custom APIs connect ERP, CRM, banking platforms and third-party tools into one data environment, so information flows automatically instead of being copied between systems by hand.

How is a custom software project billed?

FEEL IT offers fixed-scope contracts for clearly defined projects and time-and-materials contracts for projects where requirements will evolve. Both start with a free discovery consultation in which scope, milestones and expected ROI are agreed in writing.

Next step: is custom software right for your business?

If your teams rely on workarounds, your compliance team can’t see where personal data lives, or licence costs keep climbing, custom software services in Switzerland are worth evaluating. FEEL IT builds software that follows your processes, meets revFADP and GDPR requirements by design, works in your users’ languages and stays fully yours.

Book a free, no-obligation discovery consultation. You’ll leave with a clear view of scope, timeline and expected ROI, whether or not you work with FEEL IT.
