App development
Custom application development
We build web applications, business tools and digital platforms that solve the specific challenges of companies. We adapt the application to the way you work and connect it to the systems you already use.
How we build
- Around your processes
- Connected to existing systems
- Gradual rollout
- Maintenance after launch
What we build
Applications that solve a specific problem in your business.
We don't build software for its own sake. Every application replaces manual work, scattered spreadsheets or a tool that no longer keeps up with your business.
Business web applications
Applications for sales, orders, catalogues and customer work, accessible from a browser on a computer, tablet or phone.
What you gain: One system instead of spreadsheets and email.
Example: Scala – B2B Profi
Internal tools
Tools for work orders, records, approvals and internal procedures, tailored to how your team actually works.
What you gain: A clear view of who is doing what and by when.
Customer portals
Customers review orders, documents, services and invoices themselves and submit requests without calls or emails.
What you gain: Fewer routine questions for your staff.
Example: 3NET – domain management
Custom dashboards
Sales, stock, orders and key indicators from several systems in one place, with access based on user role.
What you gain: Decisions based on up-to-date data.
Booking and ordering
Systems for booking appointments and ordering services or products, with confirmations, reminders and an overview of capacity.
What you gain: Orders and appointments without double entry.
Integrations
We connect the application to your ERP, online store, CRM, accounting or supplier systems, so data is not retyped by hand.
What you gain: Data is entered once and is the same everywhere.
Modernising legacy systems
We gradually replace an outdated application or tool that nobody knows how to maintain anymore with a modern solution, without losing data.
What you gain: A more secure system that can be developed further.

Development process
From an idea to an application your team actually uses.
We develop the application in phases. You start using the first parts as soon as possible, and the next steps build on users' experience.
1. Process analysis
We talk to the people who will use the application and review how the work is done today.
Result: Scope proposal
2. Design and prototype
We prepare screen designs of the key steps so you can see and try the application before we build it.
Result: Clickable prototype
3. Phased development
We first build the core that brings the most value, then add features and connections to other systems.
Result: Working parts of the application
4. Pilot and launch
A smaller group uses the application first. We make fixes before launch and migrate existing data if needed.
Result: Application in use
5. Maintenance and upgrades
We take care of security updates and operation, and develop the application further as your business grows.
Result: Reliable operation

FAQ
What companies most often ask us about application development.
Have another question? Write to info@isaac.si.
Is it better to buy an off-the-shelf solution or develop a custom application?
If an off-the-shelf solution covers the way you work well, it is often the more sensible choice. Custom development pays off when ready-made tools require too much customisation, workarounds and manual work. During the analysis we tell you honestly which path is better for you.
We only have an idea. How do we start?
A rough description of the problem you want to solve is enough. Together we review the process and prepare a scope proposal, followed by a prototype on which you can check whether the solution meets your needs.
Can the application connect to our ERP or other systems?
Yes. We connect it through an API, web services or file exchange, depending on what the system supports. We check what is feasible before development starts.
Does the application work on phones and tablets?
We build web applications that work in the browser on computers, tablets and phones, without installing any additional software.
What happens to our old system and data?
We replace the old system gradually so that your business keeps running smoothly during the transition. We migrate existing data to the new application and check it together with you before launch.
Who looks after the application after launch?
We do. We offer long-term maintenance with security updates, monitoring and technical support, and develop the application further as needed.
How much does application development cost?
It depends on the scope, the number of user roles and the integrations with other systems. After the analysis you receive a written quote with a clearly defined scope and phases.
Let's talk about your application
Which task takes up most of your time today?
Describe how the work is done today and where it gets stuck. We will suggest how to solve it with a custom application.
