How We Chose the Best Custom Software Development Companies in Phoenix

With so many custom software development companies in the Phoenix area, it can get overwhelming searching through tons of options. From various coding languages to the platform the software lives on, there’s much at stake when selecting a knowledgeable, skilled developer to fulfill a start-up’s vision. This list includes custom software development companies based on various factors, including industries served, price, locations, and services. With that in mind, we assessed 14 companies that hit these next three marks.

Multiple Service Lines

Software developers are considered for many reasons, including great communication skills, experience, work ethic, and support services, such as aftercare and product updates. It’s important to employ a development team with the necessary skills to make your project a success. The companies on this list have a great assortment of specialties, including mobile app development, cloud services, implementation, user interface design, user interface engineering, program management, and web design.

Size of Firm

There are advantages to both large and boutique firms; it basically comes down to preference, comfort, and budget. Large development firms’ benefits include greater resources, numerous people with varying skills, and budget-friendly prices. However, a talented smaller company takes on fewer clients, offers unique, tailored software, and provides dedicated support.

Industry Focus

Software companies that cater to multiple industry segments can be powerful allies. However, this shouldn’t be considered a hard-and-fast rule, since niche development agencies might produce better results due to their innate specialties. Choosing a custom software developer that focuses on financial software when the goal is a photo editing program doesn’t make sense. Not to say they wouldn’t be competent to accomplish the goal, but it speaks to the importance of cohesion and specialty when selecting the right software development team. Some of the industries served by companies on this list include information technology, healthcare, financial services, and telecommunications.
