Gabrovo, Bulgaria
Custom software development — Gabrovo
Web systems, platforms and mobile apps built around your process, with code that belongs to you.
We build software when off-the-shelf products do not fit the way your company works: platforms such as FIX and LiftexPro, booking systems such as ZapaziChas, and call centers such as Elite Call Center. We work with Next.js, .NET and React Native on PostgreSQL. Before you receive an offer, you see a demo of the core screens.
We work from Sofia with clients across the country — remotely, and on-site when the project requires it.

Questions and answers
How much does it cost?
€3,000–€29,300, usually around €8,600. The exact price is stated in the written quote.
How long does it take?
It depends on the scope—we’ll include it in the quote. For comparison, here are examples from our portfolio: Elite Call Center — 6 months, Saitami — 6 months, LiftexPro — 8 months.
Who owns the code?
Yours. The code, data and access credentials are handed over with the project, and you can continue development with another team.
What happens after launch?
If you wish, we can maintain the project for €100–€350 per month. We specify what maintenance includes in the quote.
Can you connect the system to what we already use?
Yes, if your system has an API or can export files. We have connected Stripe, Econt's API, SIP telephony and MyPOS.
What technologies do you work with?
Next.js and React for the web, .NET and Node.js for the server, React Native for mobile apps, and PostgreSQL for data.
Custom software or an off-the-shelf system?
An off-the-shelf system is a faster start when your process is standard. Custom software is the better choice when your process is your competitive advantage or the ready-made system requires too many workarounds.
