After the grand finale tests are done and the custom software solutions are vetted as 100% stable, we start the roll-out process. Depending on the system’s complexity, we can opt in for a multi-stage release with one branch launched first, and additional locations added slowly; or a full-blown all-at-once implementation. It’s up to you to decide. If any training is required for the users, operations managers, or your in-house IT support, we can schedule the training sessions and go through the extensive supporting documentation together.

Custom Software Development FAQ

What is custom software development?

Custom software development is the process of building software for the specific needs of a specific business. A team of in-house IT specialists can perform it or the company can opt to outsource custom software development services to a third-party.

Unlike commercial off-the-shelf software, custom software is designed in accordance with a set of your specific requirements. If you want a unique set of functionality precisely addressing your users’ requirements, then custom software development is what you need.

Custom software development is complex and requires solid tech expertise, which is why businesses often turn to custom software development agencies. Their custom software development consultants help you define technical requirements and build a clear roadmap based on your business objectives so as to avoid any unnecessary twists and extra spending.

Why do businesses need custom software development?

Custom software development has a wide range of advantages. It grants companies a competitive edge because custom solutions are unique and available only to a particular company, as opposed to ready-solutions that are available to anyone on the market.

With customized software, you access unique functionality tailored to your needs. That is why companies that have special processes as their backbone or offer innovative products to the market often need custom software application development.

Even though custom software development might be more costly than ready off-the-shelf software, you can get significant profit from your custom software in the longer term. Besides that, one more advantage of custom software is that it is customizable to your budget and business expectations. It is also more secure and often much easier to integrate into your business processes.

How to choose a custom software development company?

Pay attention to the company’s experience, ask your vendor whether it has success cases with the type of software development that you want. Even a general understanding of what your business needs are, what functionality you require and what expertise is needed for that will come in handy during your search. Ensuring that your potential custom software development firm follows high-security standards is also critical.

Communication skills are important as long as the process of designing custom software is often challenging and many questions need to be discussed and properly clarified. Make sure that you feel convenient in communication with your vendor and that you are able to negotiate matters in an efficient manner. Discuss and take into account desirable delivery time and budget expectations.

What are the total costs of custom software development services?

The total cost for delivering a fully viable custom software depends on a plenty of different factors. Among the most crucial are: software scalability and complexity, set of features and capabilities, supported platforms (web or/and mobile), infrastructure requirements, potential integrations with other solutions, etc.

Moreover, SDLC (software development life cycle) implies variability and flexibility in terms of the involvement of professionals with various expertise levels, and correspondingly having different cost for their work, when building software. So the best way to understand the budget range of the planned development projects is to request a particular project cost estimation from a software development vendor.
