Custom software engineering

Software for processes off-the-shelf systems cannot handle.

oneeonee builds custom software for companies with complex internal operations. We connect existing systems, automate repetitive work and develop applications around the way your business actually works.

The starting point

Your company is already digital. Your systems often operate in isolation.

CRM, ERP, spreadsheets, email, internal tools and specialist software may all serve their purpose. Problems begin where information has to be transferred manually or where an essential workflow cannot be represented at all.

Spreadsheets travel between departments by email. Data is entered more than once. Information lives in separate systems. Existing software leaves out a decisive part of your process.
That is exactly where oneeonee comes in.

We build the missing connection.

Approach

Software that adapts to your process.

Not every business process belongs in a standard product. We analyse how the work actually flows, define the functions that are missing, and build a solution that integrates into your existing system landscape.

Services

What we build.

Custom business software

Web-based applications with their own database, roles, permissions and custom workflows — built around the actual process of your company.

System integration

When existing applications work well, they do not have to be replaced. We connect APIs, databases and internal systems and create one continuous flow of information.

Automation

Recurring work should not be done manually again and again. We automate data transfers, document generation, emails, approvals and internal workflows.

SaaS & digital products

From the first piece of business logic to a production system, we build digital products that can be operated and extended for the long run.

Mobile applications

Mobile applications for processes that do not end at a desk — built with Flutter, React Native or native iOS development.

Technology

Technology follows the task.

We do not choose technologies because they are popular, but because they make sense for the system at hand.

Your business should not have to adapt to software. Software should adapt to your business.
