Software Development Outsourcing Services

Software development outsourcing is a practice of delegating software creation, maintenance, or enhancement to a specialized external engineering team to build and deliver your software products faster without the cost of expanding the number of your own employees.

Belitsoft, recognized by Forbes Technology Council and Gartner Peer Insights, has 200+ IT professionals available for software outsourcing, and our certified staff is ready to manage your projects.

Full outsourcing gives our company complete responsibility for delivering the full scope of your software project.

We have senior experts in business analysis, architecture design, UX/UI, programming, testing, and deployment who have experience working with ERP, CRM, and data platforms, and building AI applications.

Belitsoft has successfully completed hundreds of projects, reducing development costs by 30%-40% compared to local U.S. or U.K. rates, lowering total project costs for our clients by up to 3x, and delivering software up to 2.5x faster.

Rely on our software development outsourcing services if you want a reliable long-term partner.

Custom Software Development Services

Custom software development is a process of designing, creating, testing, deploying, and maintaining reliable software tailored for the individual needs of particular companies.

Belitsoft's custom software development is built around Agile methodologies (Scrum and Kanban) combined with DevOps practices (CI/CD pipelines and automated testing) to guarantee fast software delivery and ensure that the code is secure and of high quality.

Rely on our custom software development services to transform your unique business processes or vision into intuitive digital solutions.

Unlike off-the-shelf tools, custom software development gives you wide access to microservices, AI/ML, and IoT solutions for any industry, whether it's healthcare, finance, or cybersecurity, and lets you use proven third-party components and public APIs to reduce development costs.

Custom software development services provided by Belitsoft offer experienced senior developers with more than 22 years of industry expertise across over 450 delivered large IT projects.

Our engineers follow globally recognized coding standards & security-by-design principles to maximize your ROI.

AI Automation and Agent Software Development Services

AI automation is the implementation of intelligent, autonomous systems, including agentic AI, to independently, or with a human-in-the-loop, perform data processing, decision-making, and multi-step workflow completion, using integration with business tools and systems (APIs, databases, software), allowing companies to operate with greater efficiency, speed, and scale.

Belitsoft's AI automation consulting focuses on first mapping how manual work happens today in your company and second testing a simple pilot version of an AI-supported replacement to make sure that this new software system runs as expected (can collect data from your existing business tools, understand what to do with it, and get the job done), and then scaling and monitoring it continuously to keep the AI performing under control.

Rely on our AI automation services to focus on revenue generation and strategic growth.

AI automation uses language, vision, and speech intelligence to turn raw business data (emails, documents, voice calls, scanned forms, etc.) into database records, ranked decisions, or recommendations, and then autonomously trigger and correctly execute workflow actions if only expert AI engineers design and build it.

AI automation services provided by Belitsoft offer AI developers skilled in custom agent engineering, multi-agent orchestration, domain-specific prompt engineering, fine-tuning, and integration of LLMs, third-party GenAI APIs and RAG pipelines to build conversational platforms and agentic AI solutions, so your business needs fewer staff.

We work with business owners who expect from AI automation an 90% reduction of repetitive back-office tasks, want to cut labor and operational costs by 35%, and aim to achieve ROI within 6-18 months.

Switch To The Trusted Enterprise Software Development Company Today!

Imagine that new software releases are delivered on time by your software development and testing outsourcing teams. Updates only improve your system and never break existing functionality. Your clients are happy and successful with your product.

However, your current offshore development vendor is performing very poorly in terms of speed and quality of work. Their team passively follows your instructions and never actively suggests improvements. That’s why you can’t reach your goals. You need true nearshore partners with senior, staff/lead, and principal software engineers, not just experienced by years, but by their ability to solve complex and large-scale challenges.

Our software application development company helps reputable enterprise clients with a history in the market augment or change their teams in India or other locations, and speed up and improve the quality of modernizing their current legacy software. We're their nearshore partner that can run a structured transition plan with codebase audits, documentation upgrades, and knowledge transfer sessions as they move off their India vendor. They get experienced senior+ engineers at affordable prices who can work overlapping hours, allowing communication until 4 p.m., U.S. Time Zones. We provide skilled staff who know how to add new features to monolithic systems without breaking everything and with your growth in mind (2-3 years of experience are not enough for such tasks).
