The business analysis stage of the custom software development process.

Business Analysis

We start each custom software development project with detailed business analysis. First, the business analyst from ZYNK analyzes and documents your business field, processes, and systems. Second, they outline the high-level functional requirements of the new software. The outline should match your organization’s business model. Last, they engage with business leaders and users from your organization. This way, they learn how the new software can add value to your organization.

The architecture stage of the Agile development process.

Software Architecture and Design​

Together with your product owner, our experts identify the mandatory features and layers of the new software. Then, they outline the system architecture and define the data flow and the database. Last, they prepare and share with you a high-level visual representation of the product.

The implementation stage of the custom software development process.


The development team writes the code for the required components and features of the software. In short, our project managers split the implementation stage into 2- to 3-week phases called Sprints. Then, they define for each Sprint the Acceptance Criteria and set of deliverables. In addition, they give you complete visibility and control over the results daily. In short, tracking your project works like a breeze.

The testing stage of the Agile development process.


Following implementation, our Quality Assurance engineers complete a series of activities to ensure the software meets your acceptance criteria. For example, we can perform manual or automated testing and run unit, integration, and acceptance testing.

The deployment stage of the custom software development process.

Software Deployment

The deployment is the release of the final version of the software solution to the customer or the general public. Simply put, deployment means getting your software ready for use. For this purpose, we may deploy it to a test server where your QA team can further check it. As each software is unique, we customize the deployment process based on the functional and technical specifications. In short, you will get everything you need to run it in your IT environment, including the user’s guide.

The maintenance stage of the Agile development process.


Delivering the product to you does not end our collaboration. We will make any adjustments you might need to the software and respond to requests from its users. Such adjustments may include enhancing existing features, removing outdated components, and system optimization.

What are the Benefits of Custom Software Development?

Suitability of Custom Software

Custom software aims at meeting the specific needs of your organization better than off-the-shelf solutions. Without a doubt, your organization is unique, and so are its particular needs. Of course, there is no ready-made software that will fully meet them the way custom software can.

Productivity from Custom Software

Custom software makes your organization more productive than its off-the-shelf alternatives. The custom software is designed to do what you need. Consequently, it will help your team more than the ready-made one. In a nutshell, your people will work faster and with greater efficiency.

Cost of Custom Software

The initial investment with custom software development can scare the faint-hearted. However, such software is more economical than its off-the-shelf alternatives. Specifically, you break even with the custom software a few years after launch. In addition, you own the custom solution, unlike the ready-made software. Therefore, the long-term benefits are obvious.

Integrating Custom Software

The designers of your custom software know beforehand what systems it must connect with. Consequently, they can find the right solutions for seamless integration. Yet, you can usually integrate off-the-shelf software only with other popular ready-made solutions. Connecting it to your internal software might be difficult and expensive.

Flexibility with Custom Software Development

Your organization is constantly evolving in ways that may be unique. As a result, it may have to adjust the software it uses. In general, enough users may need features that ready-made software lacks. Without a doubt, this might not be the case with the changes or additions you need. On the other hand, custom software can evolve with and for your company.

Scalability of Custom Software Development

Businesses never stop growing. As most off-the-shelf software is charged per user, its cost increases with size. In short, the growth of your company can exponentially increase your costs with ready-made solutions.  Furthermore, such software may not be able to handle the heavy load, unlike custom software. Simply put, custom software grows with your company.

Security of Custom Software Solutions

Contrary to popular beliefs, your custom software can be safer than a ready-made solution. For one thing, hackers target commercial applications with many users. For the other, fewer users mean stronger security gates. While major providers of ready-made software take security seriously, they also face way more threats than owners of custom software. With a good IT security department and affordable investments in hardware and software, you can have a foolproof custom solution.
