Integrations / 03Yellion / Karlstad

Less manual handling. Better flow.

We connect systems, data and business processes so information reaches the right place, manual steps disappear and people can spend their time on work that needs a human.

Starting point

When systems work separately, but not together.

The need for integration often appears as duplicate data entry, unreliable information or a recurring task someone has to remember. We start with the friction — not the API documentation.

01

The same data is entered more than once

Information is moved manually between ERP, CRM, web, SaaS services or spreadsheets, increasing the risk of errors.

02

The workflow stops between systems

A step is completed in one system, but the next person or service receives no signal and the process has to be monitored.

03

Legacy connections have become fragile

An integration is difficult to understand, lacks monitoring or breaks whenever one of the connected systems changes.

What the service includes

The right information, in the right place, at the right time.

A system integration should make daily work easier and data more reliable. We map the flow, build the connection and make sure errors can be detected and handled.

01

API integrations

We connect existing systems and SaaS services through stable APIs, webhooks and clearly defined data flows.

02

API & backend development

When no ready-made connection exists, we build the layer that makes data and functionality securely available to other systems.

03

Automated workflows

Recurring administrative tasks can be triggered, checked and completed automatically with clear traceability.

04

Modernisation & monitoring

We make legacy integrations understandable and robust, with logging, error handling and alerts when something needs attention.

In practice

Small points of friction that grow over time.

Typical engagement / 01

Two systems hold the same customer information.

Staff still have to move data manually. An API integration synchronises the right fields and makes discrepancies visible.

Typical engagement / 02

An Excel process has become business-critical.

Imports, calculations and follow-up are automated in a controlled flow without losing the organisation’s business rules.

Typical engagement / 03

The order ends where the next process begins.

Order, payment, delivery and feedback are connected so status follows along and the right step starts automatically.

How we work

Explore. Build. Improve.

We follow information through the organisation, find where it stops and build a flow that can be understood, monitored and changed.

  1. 1

    Explore

    We map systems, ownership, data and exceptions, then assess where automation will actually pay off.

  2. 2

    Build

    The integration is developed with clear contracts, secure handling and tests based on real-world scenarios.

  3. 3

    Improve

    Logs and measurements show how the flow performs. We catch errors early and adapt as systems or processes change.

Technology when it adds value

Robust behind the scenes.

Good integrations are barely noticed when they work. That is why we prioritise data quality, idempotency, authentication, logging and manageable errors — technology that makes processes more dependable.
