Questions

Frequently asked questions

Didn't find an answer?

Ask a question

Do you only work with companies from Bijeljina?

No. We are based in Bijeljina and work with clients across Bosnia and Herzegovina and the region. Most software, hosting and administration work is done remotely, and network and video surveillance installations are arranged on site.

How much does software or a website cost?

The price depends on the scope: the number of pages or features, integrations and content. After a short conversation about your needs we send a written quote with the price and deadlines.

Can you take over the maintenance of an existing system?

Yes. First we review the current state – the code, the servers or the network – and agree on what needs fixing, then maintenance on call or under a monthly contract.

Where are the hosting servers located?

The servers are in professional data centres with redundant power and connectivity. We back up the data regularly and check that it can be restored.

How can I try the RTK signal?

Send an inquiry with the model of your receiver or terminal and your location. We open trial access so you can check RTK FIX in the field, and you can see the coverage at rtk.ba/pokrivenost.
