Transparent pricing models
for your business goals

The cost of software development services is influenced by several key factors. These include project complexity, the sophistication of security features, the team’s expertise level, the testing scope, and timeline requirements. While these factors form the foundation of pricing, the choice of technology stack affects both initial development and long-term maintenance expenses, contributing to the final custom software development cost.

Fixed price

This model provides maximum cost predictability, regardless of the actual time or resources required. A set price is established at the project start based on well-defined requirements and deliverables. Any scope changes are accommodated through a formal change request process, which helps maintain project flexibility but may incur additional fees.

This model works best for projects with clear specifications where clients prefer predictable budgeting and minimal involvement in day-to-day development decisions.

Neontri assumes full responsibility for delivering the software according to the agreed scope and timeline. Our team handles all project risks, resource allocation, and quality assurance.

Time & materials (T&M)

This approach provides the agility to adapt to changing business needs and technical requirements. It offers maximum flexibility in both development and pricing, as billing is based on time spent and resources used.

This model requires efficient project management to control costs. At Neontri, we enable regular progress tracking and transparent reporting to improve project visibility and minimize the risk of cost overruns.

The T&M model is best suited for projects with evolving requirements or those where the scope is not fully defined from the beginning. It’s also ideal for co-development efforts, where custom software developers work with the client’s internal teams, fostering knowledge sharing and seamless integration of development practices.

Fixed-team

In the fixed-team model, a dedicated team is assigned to work exclusively on the project for a defined period. The team becomes deeply familiar with your business context, leading to improved efficiency and quality.

This approach to custom software development is suitable for long-term projects that need continuous development, support, and maintenance. It offers an optimal balance of cost control and development flexibility. It also encourages team ownership, fostering better collaboration, productivity, and quality outcomes.

Build-operate-transfer (BOT)

This is a staffing arrangement in which Neontri, as a software services provider, builds and manages a dedicated team for a set period, with the agreement to transfer ownership and control to the client once everything is fully operational.

The BOT model works best for innovative or experimental projects where organizations want to minimize initial risk while developing new technology solutions. It helps them test and validate their solutions.

This model is also well-suited for companies that lack internal technical expertise. It allows them to start quickly without building an in-house team immediately while we manage deployment, maintenance, and optimization until a handover is possible.
