How To Choose The Right Software Development Company In Bulgaria
Before making a decision, consider the following:
Vertical experience. If you’re building a fintech product, look for a team with fintech references — not just general software development credentials.
Engagement model. Some Bulgarian companies excel at fixed-scope projects; others are built for dedicated team augmentation. Make sure the model matches your needs.
Communication practices. Ask about sprint cadence, reporting formats, and how they handle requirement changes mid-project. A good partner documents everything.
IP and security. Confirm that contracts include clear IP assignment, NDA provisions, and data security policies — especially important for regulated industries.
Portfolio alignment. Review case studies that match your project type and industry, not just the tech stack.
