How do we proceed?

What do you sell, and to whom? In a single meeting we pin down scope, timeline and the quote.
Design
Home page and critical screens first. Nothing moves to code until you approve.

Code, content entry, speed and SEO settings. You see every stage on a staging site.
Launch and care
We launch on our own servers and handle updates and support. We stay after delivery, too.
What we have done with this service
Villa Vakti
Rental platform for a large villa portfolio across different regions.
Services we provide
- Villa rental platform and software
- Search engine and advertising work
- Hosting and technical support
The partnership with Villa Vakti, which began in 2018, has grown into a rental platform that gets a large villa portfolio to the villa a guest is looking for by the shortest path.
About Villa Vakti
On the first screen, visitors start searching by choosing check-in and check-out dates, number of guests, villa category and region. Advanced search goes down to more detailed filters, while the “Most popular villas” showcase on the home page speeds up the decision.
In the rental industry, trust is a precondition of sales. That is why the TÜRSAB guarantee and the reservation line sit on the first screen, and the WhatsApp button is reachable on every page.
Scope
Interface design, rental software, content structure and search engine optimisation were carried out by Kariha.
Han Emlak
Real estate site where sale and rental listings are managed from a panel.
PlatformReal Estate Website SoftwareHan Emlak is a real estate site running on the real estate software we developed ourselves. Listings are entered by the office from the panel and published on the site instantly.
About Han Emlak
Visitors can filter listings by category and location; price and key features are visible at a glance on each listing card. For a listing they like, they can reach the agent with a single tap by phone or WhatsApp.
Why ready-made real estate software?
