The Best Software Development Companies in Bulgaria
for Software Development Outsourcing
While Bulgaria may not always be the first country that comes to mind for software development, it's quickly establishing itself as a rising star in the global outsourcing market. Strategically located in Eastern Europe, Bulgaria offers a potent mix of affordability, technical talent, and business-friendly infrastructure that’s turning heads in the tech world.
One of the biggest advantages? Cost-effective expertise. Bulgarian developers offer competitive hourly rates that are significantly lower than those in Western Europe or North America. But more importantly, they bring a level of technical excellence that rivals global leaders. According to the latest Kearney Global Services Location Index, Bulgaria ranks among the top 20 outsourcing destinations globally, with a score of 5.59 out of a possible 7.09. This reflects a strong combination of financial attractiveness, digital resonance, and talent availability.
A Thriving Tech Talent Pool
Bulgaria is home to over 101,000 ICT professionals, according to the Emerging Europe Future of IT Report. That’s a substantial figure for a country with fewer than 7 million people. Many of these professionals are fluent in English and have strong academic foundations, thanks to Bulgaria’s robust education system. More than 50 universities offer IT programs, producing over 2,000 tech graduates every year.
Sofia remains the central tech hub, hosting the largest share of Bulgaria’s software development companies. However, cities like Plovdiv, Varna, and Burgas are rapidly becoming viable alternatives due to government-backed tech initiatives and growing local ecosystems.
Areas of Expertise Among Bulgarian Developers
Bulgarian software companies are highly experienced in mainstream programming languages like Java, JavaScript, PHP, and C#. But what truly sets them apart is their growing expertise in advanced and emerging technologies:
- Cloud Infrastructure: Many Bulgarian firms offer DevOps and cloud-native development using platforms like AWS, Azure, and Google Cloud.
- IoT Development: Companies in Bulgaria are actively building scalable IoT solutions across industries like manufacturing, healthcare, and logistics.
- Cybersecurity: With a focus on data protection and compliance, several Bulgarian providers offer world-class security engineering.
- Big Data & AI: Firms are increasingly working on machine learning models and big data architecture to support real-time analytics and predictive modeling.
This wide range of capabilities makes Bulgaria a one-stop destination for both legacy systems modernization and cutting-edge digital transformation.
Competitive Advantages of Bulgarian Outsourcing Companies
Highly Skilled Workforce: Bulgaria has long emphasized STEM education. Developers are known for their strong problem-solving skills, collaborative mindset, and adaptability.
- Cultural Compatibility: With its EU membership and Western-aligned business practices, Bulgaria offers a cultural and regulatory environment similar to Western Europe and North America.
- Time Zone Advantage: Located just two hours ahead of GMT, Bulgaria’s time zone allows for convenient collaboration with both European and U.S. clients.
- Data Protection Compliance: As an EU member, Bulgaria complies with GDPR regulations, ensuring high standards for data privacy and security.

Steps to Take Before Outsourcing Software Development
You’ll find all the details you need—from hourly rates to technical specialties—on our curated list of the top 15 software development companies in Bulgaria. But before choosing a partner, it’s essential to plan strategically. Here’s how to approach the selection process.
Choosing a Software Development Company in 7 Steps:
1. Set Out Your Objectives and Project Time Frame
Before searching for a development partner, clearly outline your goals. Define the scope of the software, desired functionality, and your expected delivery window. Tools like Lucidchart or Balsamiq can help you create quick mockups to visually express your requirements.
Be realistic about your MVP and final launch goals. Use these to set expectations during negotiations with Bulgarian companies or other outsourcing destinations.
2. Start Searching and Shortlisting by Reputation
If you're looking specifically for Bulgarian developers, we've already vetted the top companies. But if you're expanding your search, consider platforms like Clutch.co and GoodFirms to find verified reviews and ratings. Look for consistent praise across third-party sites and the company’s own digital footprint.
3. Delve Into the Companies’ Case Studies and Portfolios
Review detailed case studies to ensure a company has worked on projects similar in complexity and scope to yours. For example, companies listed on our custom software development page provide insight into past work that aligns with enterprise solutions, app builds, or systems integrations.
If portfolios aren’t available publicly, request samples or anonymized summaries. Also, check employee LinkedIn profiles for technical alignment.
4. Gauge Their Tech Expertise
Bulgaria is known for developers skilled in Java, PHP, JavaScript, and C#, but also emerging technologies like AI development and cybersecurity.
Ask the company about their core stack, testing methodologies, and tools used in deployment pipelines (e.g., Docker, Kubernetes, GitLab CI/CD). If you’re building a highly specialized product—such as in fintech or IoT—make sure they have relevant domain expertise.
5. Assess Their Project Management Capabilities
Look for firms that use Agile methodologies like Scrum or Kanban. Companies that follow iterative approaches are more likely to deliver functional, flexible software. Ask for clarity on how they manage sprints, documentation, QA cycles, and client feedback loops.
Request access to their preferred project management tools (e.g., Jira, Trello, or Asana) for transparency.
6. What Are Their Security Practices?
Data security is critical, especially if your product involves sensitive information or handles user data. Ensure the company is GDPR-compliant (Bulgaria is an EU member), and ask about practices such as two-factor authentication, end-to-end encryption, and secure code review.
You may also refer to EU-wide standards for data protection like the European Data Protection Board or the ISO/IEC 27001 framework.
7. What Is Their Software Maintenance Policy?
Development doesn’t end with deployment. Whether it’s bug fixes, updates, or feature expansions, software maintenance is a long-term concern. Ask whether post-launch support is included or requires an additional retainer. We recommend budgeting at least 15–20% of your total software development cost for ongoing maintenance.
If you don’t want to rely on one provider long-term, consider supplementing your strategy with staff augmentation services.
Can’t Find a Bulgarian Software Company You Like?
If none of the top software companies in Bulgaria feel like the right fit, explore software development outsourcing in other countries. You’ll find vetted rankings for regions such as:
By following this 7-step approach, you’ll be better positioned to evaluate potential partners and confidently outsource your next development project.
