Custom Software Development Services

We build high-quality custom software and help you update your outdated systems and migrate to up-to-date technologies. Leverage our US- or European-based teams to enhance your in-house expertise, deliver several projects in parallel, or fully outsource project development.

Ascendix is a custom software development company from Dallas with international offices in Europe. We provide full-cycle tailor-made app development services to help you achieve your business goals, meet your end-users needs, and empower your company with top-grade solutions.

We build web, desktop, and mobile applications for small businesses and enterprises.

When you hire developers at Ascendix, you can choose the most relevant engagement model based on your business needs and budget.

If you want to actively manage our US-based, blended, or offshore teams, we can offer you a dedicated team model. In case you prefer to delegate all product development, we can fully undertake the process.

Our Clients Say

Saimir Qalliu Colliers about Property Listings Portal Development

Saimir Qalliu Colliers about Property Listings Portal Development

Ascendix Technologies migrated our business from our old CRM to Microsoft Dynamics, customizing it for both our industry and our specific workflow at the time. So, instead of spending 10 hours to provide a report or service to a client, our brokers can now do it 200% faster and be as efficient and probably more effective than they would otherwise have been a year ago.

We did some audits about how good the Ascendix service was and got very good feedback. But the main part why I was going with Ascendix was not technical or about our requirements. It was the spirit of you, Ukrainians, and the passion for your work. That was for me important. In digitalization, the smallest part of success is really the IT skills. It sounds weird, but I think the biggest part is passion and structure. And in the end, it was the reason why I decided to work with Ascendix Technologies.

What is custom software development?

Custom development is the process of creating tailored-made technology solutions specific to your particular business or end-users’ demands.

How could my business benefit from custom software development?

Unlike packaged or ready-made solutions, custom software provides your business with such benefits:

Meet specific requirements

If you have specific and unique business needs, we will help you meet them. We build bespoke solutions that cater to clients’ requirements and include particular custom app features that end-users love.

Be flexible

You can make changes, improve your custom software, and add new features when needed. It becomes possible with the help of high scalability embedded by our expert custom software developers.

Reduce costs 

Template and out-of-the-box solutions can provide your business with extra features that you may never use. Unlike packaged platforms, tailor-made product development allows you to build only the features you need. This way, your app development costs will be lower in the long run.

Get technical support and maintenance 

When your business grows, your application software should be improved and scaled. You can enhance the functionality or add new features to your custom app in a fast and cheap way.

How to choose a custom software development company?

When you decide to build solutions tailored to your specific business needs, it becomes important to choose the right technology vendor. However, there are many web agencies and they seem to provide quite similar services. So, what are the key indicators of an experienced provider?

Technical background and domain expertise 

Pay attention to the expertise of a company in building solutions with similar functionality within your business domain.

Portfolio and reviews

Clients’ reviews are one of the best ways to see how a company delivers its projects. Well-known platforms such as Clutch, GoodFirms, and The Manifest will help you get relevant testimonials and even contact the company’s clients to get some feedback about their collaboration. Portfolio and case studies also allow you to check the agency’s expertise and experience level.

Tech stack and engagement models

If you want to get a scalable and feature-rich app, the technology company should use a shortlist of technologies for each solution. Unless the agency specializes in everything, then you may get a low-quality application without high scalability and maintainability. Also, flexible engagement models are an important indicator that the app development company has enough expertise to offer dedicated, blended, or offshore teams.

Why Ascendix as a custom software development company?

Flexible Engagement Models

We offer our clients on-demand, dedicated, blended, and offshore engagement models to meet the requirements of any project. If you hire software developers at Ascendix, you get a lot of choices. In case you want to actively manage our US-based, blended, or offshore teams, we can offer you a dedicated team model. If you want to avoid active engagement, we can fully undertake the process.
