Our Clients Say

Saimir Qalliu Colliers about Property Listings Portal Development

Saimir Qalliu Colliers about Property Listings Portal Development

We searched online for companies that worked with Microsoft Dynamics with a background in real estate. We found Ascendix Technologies and liked what they’d done for their other clients, so we interviewed them. They were skilled, responsive to our pitch, and willing to customize the platform to our needs, so we hired them. 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. They perform regular updates on the platform every 2–3 years and execute any technical improvements that Microsoft pushes through.

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 software development is the process of creating tailored-made software 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, custom software development 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, custom software 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. With the help of custom software development companies, you can improve 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 custom software, it becomes important to choose the right software development company. However, there are many web agencies and they seem to provide quite similar services. So, what are the key indicators of an experienced software provider?

Expertise in custom software development

Pay attention to the expertise of a company in building custom software for small businesses and enterprises.

Portfolio and reviews

Clients reviews are one of the best ways to see how a custom software development 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 custom app, the software 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 custom software development company has enough expertise to offer dedicated, blended, or offshore teams.
