Efficiency Through Automation

When systems talk to each other, your business grows faster.

In many companies, critical systems work alongside each other rather than together. Accounting, ERP, CRM, website, shop or logistics are not cleanly connected – resulting in high manual effort, error sources and a lack of transparency.

We develop custom integrations that exchange data securely, in a structured manner and in real time between your systems – tailored to Swiss requirements, existing software and future scalability.

Architecture

The right API architecture for performance and maintainability

We consult and develop APIs not by trend, but by use case. REST for standard applications, GraphQL for flexible frontends or webhooks for real-time events.

REST & Modern Standards

The standard for modern business applications: fast, resource-efficient and easy to scale. Ideal for connecting mobile apps and web platforms.

GET /api/v1/customers/1024
{
"id": 1024,
"type": "business",
"active": true
}
Schema Validated

GraphQL & SOAP (Legacy)

We also master complex SOAP interfaces for enterprise systems or deploy GraphQL when frontend performance and precise data queries are critical.

query {
user(id: "1024") {
name
orders { total }
}
}
Integrations

An ecosystem, not just software.

We connect ERP, e-commerce and legacy systems into a seamless unit. Data flows automatically, errors disappear.

Abacus, Bexio or SAP

We develop a stable, extensible data pipeline for financial, customer and goods flows – with clear validations, complete logging and continuous monitoring. All relevant data is synchronised across systems and provided in a consistent structure. No manual exports, no Excel workarounds – but a central, reliable single source of truth.

E-Commerce

Shopify & WooCommerce integrations for logistics and tracking.

Headless CMS

Central data management for web, app and print via API.

Legacy Modernisation

We build modern APIs around existing legacy systems. Make your legacy database ready for mobile apps and cloud applications, without the risk of replacing the core system.

Security & Performance

Scalable, secure APIs for business-critical systems

An API is only as good as its stability under load. We implement rate limiting, intelligent caching strategies and scalable microservice architectures.

  • Enterprise Security

    OAuth2, JWT, role-based access control and OWASP compliance.

  • Lifecycle Management

    Versioning, deprecation strategies and Swagger/OpenAPI documentation.

SEO & AI Ready

How APIs support SEO, dynamic content & AI search

Technical SEO is based on data. We structure your API outputs so that search engines and AI models understand them optimally (Schema.org / JSON-LD).

Google Indexing API

For job portals and event platforms: get new content indexed immediately.

LLM Preparation

Provide data so that AI models (RAG) can give reliable answers.

Industry Expertise

API Solutions for Every Industry — Because Systems Need to Talk to Each Other

Every industry has its own system landscapes, data formats and integration requirements. We know the common industry software ecosystems and develop APIs that seamlessly connect your existing systems — secure, performant and future-proof.

Financial Sector & Trust

Secure API connections to accounting software, banking interfaces and compliance systems. OAuth 2.0, encryption and audit logging for regulated environments.

Healthcare & Pharma

HL7/FHIR-compliant interfaces for clinic systems and practice software. Secure patient data transfer and integration of laboratory and diagnostic systems.

E-Commerce & Retail

Payment gateway integrations, PIM connections and logistics APIs for online shops. Real-time inventory synchronisation and multi-channel distribution.

Industry & Manufacturing

ERP and PIM interfaces for SAP, Abacus and industry-specific systems. IoT data connections and machine-to-machine communication via REST and MQTT.

Hospitality & Tourism

Integration of POS systems, reservation platforms and delivery service APIs. Channel manager integration for hotels and automated availability synchronisation.

Professional Services

CRM integrations, calendar synchronisation and automated workflow APIs. Integration of project management tools and time tracking systems.

Education & Research

LMS integrations, student management APIs and research database interfaces. Single sign-on and LDAP connections for university infrastructures.

Public Sector

E-government interfaces, open data APIs and secure citizen data integrations. Connection to cantonal and national administrative systems.

Integrations that accelerate processes

API Development & Interface Programming for Businesses in Switzerland

When data is transferred manually between systems, unnecessary costs, errors and delays arise. With professional API development, we connect your business systems so that information flows securely, in a structured manner and in real time – from ERP and CRM to website, shop and business applications. The result: less operational friction, better data quality and an IT foundation that can scale with your company.

Your systems don't talk to each other yet?

Let us examine together where APIs can enable efficiency, security and growth in your company.

API development means we create a technical interface through which two or more systems automatically exchange data. Typical examples include synchronising customer and order data between website/shop and ERP, transferring invoices to accounting, or creating leads from forms directly in the CRM. For businesses, this reduces manual work, prevents duplication and increases data quality across all departments.
Virtually all systems that provide an API or can be integrated via files/events. Common integrations include ERP and accounting (e.g. Abacus, Bexio, SAP), CRM (e.g. Salesforce, HubSpot), CMS (e.g. TYPO3, WordPress, Craft CMS), e-commerce, logistics, PIM/DAM, DMS (e.g. SharePoint/DocuWare) and specialised industry solutions.
Costs depend heavily on scope and complexity: number of systems, data objects, transformation logic, real-time vs. batch, error handling, security and monitoring. We recommend: first a brief discovery (goals, data flows, risks), then a reliable effort estimate with milestones.
A lean MVP can be realisable within a few weeks depending on system access and data clarity. Larger integration projects take longer, as additional topics like data cleansing, versioning, load tests, security reviews and rollout strategy become relevant. We work in clear stages so that timeline and budget remain transparent.
REST is the standard in most business scenarios. SOAP is often found in older or heavily regulated systems. GraphQL is particularly useful when frontends need to retrieve data very precisely. We make the decision based on your system landscape, security requirements, data volume and future plans.
Stability comes from clean error handling, retry strategies, idempotency, logging, monitoring and alerting. We define clear rules for timeouts, data conflicts and faulty records. For business-critical integrations, we recommend SLAs and an operational setup with health checks and incident processes.
Very important, because APIs often provide access to core processes and sensitive data. We implement authentication (OAuth2/JWT, API keys), role-based permissions, rate limiting, input validation and TLS encryption. We also pay attention to auditability and compliance requirements.
Often yes. If a system does not offer a clean API, there are alternatives such as SFTP/file interfaces, webhooks, database views or event-based approaches. It is important that stability and maintainability are ensured.
The biggest lever is the elimination of manual work steps and the reduction of error costs. Processes become faster, data is consistent and analyses become possible in the first place. Additionally, a scalable foundation is created for headless architectures, automation and AI use cases.
