Web Application Development Services in Switzerland

When a standard website is not enough, a web application can provide the functionality your business actually needs. SwissLayer develops custom web applications and web-based software for businesses in Zurich, Geneva, Lausanne and across Switzerland.

We build applications around business workflows, user roles, data, integrations and specific operational requirements.

When a Web Application Makes More Sense Than a Website

A standard website primarily presents information. A web application allows users to interact with functionality, data and business processes.

A web application may be appropriate when your users need to:

  • Log into an account
  • Use a dashboard
  • Make bookings
  • Access customer-specific information
  • Interact with other systems
  • Manage information
  • Submit requests
  • Manage business processes
  • Work with structured data
  • Business objectives
  • User journeys
  • Existing designs or website structures
  • Content and CMS requirements
  • Required functionality
  • Third party tools and integrations
  • Technical requirements

For example, a website might explain your services and provide a contact form. A web application could allow customers to log in, manage their information and submit requests through a defined workflow.

This could include customer portals, booking systems, internal tools, marketplaces, management systems or other custom platforms.

Not every business needs a custom application. If an existing SaaS product, CMS or no-code platform already handles the required functionality, custom development may not be necessary.

What We Develop

Customer Portals

Web applications that allow customers to log in, access relevant information, submit requests or manage their account.

Business & Internal Tools

Web-based systems designed around internal processes, recurring tasks, information management and operational workflows.

Booking & Reservation Systems

Applications supporting bookings, availability, requests and related processes where required.

Marketplaces

Platforms that connect different groups of users, providers, customers or listings through defined workflows.

Custom Web Platforms

Applications built around specific business requirements that cannot be reasonably handled through a standard website or platform.

Business Software

Web-based software designed around a company’s internal requirements, workflows and data.

The functionality depends on the application. Features are defined according to the actual requirements rather than added simply because they are available.

Custom Web Application Development

Custom development can make sense when standard software does not fit the way your business operates.

Website wireframes and interface sketches for custom website development

It may be appropriate when you need:

Specific user roles and permissions

Custom business workflows

Specialised data structures

Connections between existing systems

Functionality not available through standard CMS platforms

Web-Based Software Development

For example, if your team currently manages a specialised process across spreadsheets, emails and several separate tools, a custom application may provide a more structured way to handle that workflow.

Custom web application development should solve a specific business problem. It should not be chosen simply because it sounds more advanced.

The first step is understanding what the application needs to do and why existing solutions do not adequately meet that requirement.

Web-Based Software Development

Web-based software allows authorised users to access business functionality through a browser rather than relying on a traditional desktop application.

Depending on the project, this can include:

Internal business systems

Customer management tools

Workflow platforms

Dashboards

Data management systems

Business portals

For example, instead of keeping operational information across spreadsheets and separate email conversations, a web-based system can provide authorised users with a defined place to manage the relevant information and tasks.

The application structure depends on its users, functionality, data and existing technology environment. Requirements should be established before deciding how the software should be developed.

User Roles, Workflows & Permissions

Many web applications are built around different types of users.

An administrator may manage the system, staff may handle operational tasks, while customers may only access information relevant to their own account.

This can involve different:

Accounts

Permissions

Dashboards

Actions

Data

Workflows

For example:

Administrator → manages system settings and information Staff → handles assigned operational tasks Customer → accesses their own account and relevant services The exact structure depends on the application. Defining these roles early helps establish what each user should be able to see and do.

This is particularly important when the application handles different types of information or when users need different levels of access.

Frontend & Backend Working Together

A web application has more than the interface users see. Different parts of the system work together to support the required functionality.

Frontend

The frontend is the part users interact with, including screens, forms, navigation, dashboards and other interface elements.

Backend

The backend handles application logic, processes, data handling and other functionality that operates behind the interface.

Database

Where required, application data needs to be stored and managed in a structured way.

APIs

APIs can allow the application to communicate with external websites, software, databases or other systems.

Together, these components form the foundation of many full stack web applications.

The technical structure should be selected around the application’s requirements rather than forcing every project into the same approach.

Applications That Connect With Existing Systems

Responsive website layouts displayed across desktop, laptop, tablet and mobile devices

Your application may need to work alongside systems your business already uses.

Potential connections can include:

Existing websites

Databases

CRM systems

E-commerce platforms

Booking systems

APIs

Business software

Internal tools

The existing technical environment should be reviewed before deciding how systems can communicate.

For example, an application may need to retrieve information from an existing system, send information back to it or use an external service as part of a specific workflow.

The feasibility of each connection depends on the existing system, available access, APIs and technical environment.

Web Applications for Existing Business Processes

Many application projects start with a business process rather than a technology requirement.

You may have a process where:

Employees enter the same information repeatedly

Customers send requests by email

Teams rely on spreadsheets for a complex workflow

Information is stored across multiple systems

Internal processes depend on manual handovers

A web application can potentially provide a central place for users to complete defined tasks and work with relevant information.

For example, a customer request could move from submission to staff review through a defined workflow rather than being managed through separate emails.

The application should be designed around the actual process rather than simply replacing an existing spreadsheet or manual step with software.

What Businesses Use Web Applications For

Customer Self-Service

Provide customers with access to information, requests, account functions or other relevant services through a dedicated application.

Internal Operations

Support teams with structured workflows, recurring tasks and controlled access to business information.

Booking & Scheduling

Support appointment, reservation or availability related workflows where these form part of the business requirement.

Data & Reporting

Give authorised users access to relevant business information and reporting views within the application.

Marketplace Operations

Support interactions between different user groups, listings, transactions and related workflows where required.

Custom Business Processes

Develop functionality around specialised processes that do not fit comfortably within standard software. The appropriate use case depends on the business problem, users and workflow rather than the technology itself.

What We Consider Before Building the Application

Modular WordPress website structure with reusable content sections and responsive layouts

There is no single structure that suits every application.

Before development, relevant considerations can include:

  • Users
  • Data
  • Integrations
  • Expected functionality
  • Roles
  • Business rules
  • Security requirements
  • Future requirements
  • Users
  • Roles
  • Data
  • Business rules
  • Integrations
  • Security requirements
  • Expected functionality
  • Future requirements

A simple internal tool may have very different requirements from a customer portal or marketplace.

For example, a system with three user types may require different dashboards and permissions for each group, while an internal reporting tool may focus more heavily on data access and reporting.

The application’s structure should therefore be considered after the business requirements and workflows are understood.

Security, Access & Data

Web applications can handle information that should only be available to specific users.

Depending on the project, requirements may include:

  • User authentication
  • Role based access
  • Secure connections
  • Protection of sensitive business information
  • Access permissions
  • Data handling
  • API access
  • User authentication
  • Access permissions
  • Role based access
  • Data handling
  • Secure connections
  • API access
  • Protection of sensitive business information

You may also be wondering whether changing the CMS means rebuilding the entire website or losing the design your business already uses.

The first step should be understanding the existing website rather than immediately replacing it.

We can look at how the content is structured, how editors currently work with the CMS and where the existing setup creates unnecessary friction. The existing design, content and functionality can then be considered before deciding whether the right solution is improvement, restructuring or a different CMS.

You may already have a starting point for your application.

This could include:

Web Application Development From Existing Designs

Figma designs

UI designs

Wireframes

Prototypes

User flows

Technical specifications

Existing material can provide a useful foundation for development.

However, application development may also require details that are not visible in a static design, such as:

Interactive states

User roles

Responsive behaviour

Application workflows

Error states

Forms

Data requirements

Where design support is required, this can connect with our

You may already have a web application but need further development.

Potential requirements can include:

Existing Application Development & Improvement

An existing application should first be reviewed together with its technical environment before deciding what can be changed or extended.

New functionality

Additional user roles

New workflows

API connections

Interface improvements

Backend changes

Database related work

This helps establish whether the requirement involves the interface, application logic, database, integrations or a combination of these areas.

If the existing system is outdated, undocumented or dependent on third party technology, its current structure and access requirements should be assessed before defining the development scope.

Our Web Application Development Process

01

Understand the Business Workflow

Identify the business problem, users, roles, processes, data and functionality the application needs to support.

02

Define the Application Structure

Map important workflows, permissions, functionality and relevant system requirements.

03

Design the Interface

Review existing designs or establish the required application interface and user flows.

04

Develop the Application

Build the frontend, backend, database functionality and required integrations according to the agreed scope.

05

Test Workflows & Access

Test relevant user journeys, permissions, forms, data handling and integrations.

06

Launch & Handover

Prepare the completed application for deployment and handover according to the project requirements. The development scope and duration depend on the functionality, users, integrations, data requirements and overall complexity.

When Custom Software Is Not the Right Choice

Custom software is not automatically the best solution.

A standard SaaS product, CMS, no-code platform or existing business tool may be more appropriate when:

The required functionality already exists

Custom functionality is minimal

A standard product adequately solves the problem

The business does not need a specialised workflow

The right solution should be based on the business requirement.

If a standard platform can handle the required functionality effectively, custom development may not be necessary.

For example, building a custom system for a straightforward content-managed website may add unnecessary complexity when an established CMS already provides the required functionality.

UI/UX requirements can be considered alongside application architecture and development requirements.

03

Existing Systems Considered

Relevant websites, software, databases and integrations can be considered when defining the application requirements.

04

Custom Functionality Where It Is Justified

Custom development is considered when standard tools do not adequately support the business requirement.

The approach should follow what the application needs to do, rather than forcing the project into a fixed technology or development model.
