Web application development: custom software in the browser
An internal system for your team, a customer portal or an online service, with no installation and on any device. Custom development with a small first version, and the source code stays with your company.
A web application is software used in the browser: nothing to install, it runs on computers, tablets and phones alike, and every update reaches everyone at once. It is a good fit for internal systems, customer portals and online services when off-the-shelf software does not match the process. Lorz Kft. in Miskolc, Hungary builds custom web applications with a small, usable first version, on the same technology lorz.hu runs on.

Web application development: what to know before you decide
01Website, web application or mobile app?
A website mainly informs and brings in enquiries. A web application does work: signed-in users create, change and look up data, according to roles and rules. A mobile app is installed on the phone and makes fuller use of its hardware and background operation.
For business tasks a web application is usually the right choice: one codebase for every device, no app store approval, and updates reach everyone at once. If the goal is enquiries, we build a website; if you need the phone's capabilities, a mobile app.
02Internal system or customer portal?
An internal system is used by your team: few, known users and many business rules, for example a business management system, a custom CRM or work order software.
A customer portal is also used by outside users: sign-up, password resets, a simpler but polished interface, higher load and stricter security, for example an online booking system. Often the two are one system with two interfaces.
03Small first version, then growth
Most software projects slip because they try to do everything at once. We start with the main process: the first version contains only what the work cannot be done without, and the rest follows from real use. Operations, updates and monitoring can be handled as part of our IT support.
How it works
- 1
Needs and process review
Who uses it, for what, with which data, and where the work gets stuck today.
- 2
First version plan
Only what the main process cannot work without. The rest waits for round two.
- 3
Development in short cycles
A usable state every few weeks, with real data and feedback from key users.
- 4
Rollout
Data migration, training, a short parallel run, then go-live.
- 5
Operations and growth
Monitoring, backups, bug fixes and further development based on real use.
What affects the cost?
We quote after reviewing your process. These are the main factors:
- 01
Roles
One internal team, or managers, staff, partners and customers with different permissions.
- 02
Processes and rules
How many main processes, and how many exceptions, approvals and calculations they contain.
- 03
External users
Customer portals need sign-up, password handling, more capacity and stricter security.
- 04
Connected systems
Invoicing, webshop, Microsoft 365, couriers: each is a separate connection.
- 05
Data migration
Cleaning and importing data from spreadsheets and older systems.
- 06
Operations
Hosting, backups, monitoring, bug fixes and further development on a monthly plan.
We give a fixed price after the discovery phase, in writing and itemised — we walk through the factors above together in the first, free consultation.
