Websites and online stores, mobile apps, custom internal systems, integration and hosting — from a simple site to full company IT, from one team, in plain language.
Enquiries usually get a reply the same day, on weekdays.
Presta.hu and delixor.com are our own products — we handle both the development and the day-to-day running.
Korelvision is a full-service IT and web development team. From a website to company-wide systems, we solve it all in one place — with more than ten years of experience.
The clients range from sole traders and small businesses to companies with revenue in the billions of forints. The same team handles a simple website and a complex internal system alike.
Own products are built here too — Presta.hu and delixor.com. We do not just develop them, we run them every day — so we know from the inside what keeping a system alive really takes.
No technical knowledge needed. Once the goal and the current pain points are clear, the build is our job.
Shows what the company does, and people find it. Fast, works well on a phone, and editable later without help.
Orders, shipping, payment, several languages and currencies if needed. Set up so daily order handling takes as few clicks as possible.
An app for customers or the internal team: orders, couriers, warehouse, job sheets. On iPhone and Android alike.
The program used all day long: stock, orders, customers, reports. Shaped exactly around how the company works.
Invoicing, accounting, courier and store connected, so data never has to be copied from one system to another by hand.
Backups, updates, security — for smooth, worry-free operation. When something stalls, there is someone to turn to.
A digital helper can now be built that knows a company’s own prices, past orders and internal rules. It gives no generic answers — it works from how the company actually operates, and it does the tasks someone types out by hand today.
It answers staff questions in seconds: what something costs, what was promised to a client, where a document is.
It answers recurring questions, checks where an order is, and calls in a colleague when a human decision is needed.
It reads incoming invoices, delivery notes and orders and enters them into the system — no typing.
It goes through orders and tasks and shows where things slip, what keeps repeating, and what is worth handing to a machine.
There is no need to automate everything at once. Whatever replaces the most manual work comes first.
It is not about flashy features, but about what eats the most time day to day. That is where the build saves the most.
Often a small change is worth more than a big build. When that is the case, that is what we recommend — even if it means less work for us.
What we build, we look after. Six months on, the same team is still available.
One team and one point of contact who knows how things work and why they were built that way.
Half an hour, free of charge. Clarifying the goal and the current situation, with questions about the daily routine.
One page: what gets done, how long it takes, what it costs. Clear, with no surprises.
Progress is visible every week — on a link, open any time.
A walkthrough and written notes at handover. From then on, the team stays available.
No finished idea needed. Most work begins with a short message: what the goal is, and where things stand now.
