How To Choose The Right Partner for Software Development

Here are some tips on how to choose a suitable company for your business needs.

Check out the expertise and team’s skill set

Make sure you work with qualified specialists who offer quality services. It’s essential to work with a certified team of experts as they can suggest how to improve your product, release bug-free software, and ensure high user satisfaction with your product.

You can scrutinize the company’s services and see what technologies they use (Ml, AI, big data, etc.). Also, make sure that the team has experts in the finance industry to build a relevant product.

As for developers, they should hold expertise in some of the most widely used fintech programming languages:

  • Python
  • Java
  • C++
  • VBA
  • SQL
  • Scala
  • R

Don’t forget to look through the portfolio. You can find similar cases and figure out what challenges and results the company managed to obtain.

Ensure user data safe storage and use

Cybersecurity should be a cornerstone of your digital product. Do not neglect safety issues when developing fintech solutions. That’s why your partner should be well aware of all possible harms and threats on the web.

Ask software development companies about their approaches to security problems and what solutions they offer to mitigate issues on the web.

Find out what regulations and protocols they follow when developing products.

Discuss pricing in advance

Of course, you can check out service charges on the software development company’s website, but discuss the project pricing. Multiple factors will impact it.

Pay attention to the pricing based on hours, programmers’ qualifications, or turnkey service. You can discuss these aspects before placing your order and then compare the best variants.

Read reviews

Start with the company’s page and then move to the independent resources like Clutch, Goodfirms.

These resources will help you get a comprehensive picture of companies. You can assess their rating and find out what clients tell about their services.

Pay attention to the company capacity

Depending on your goal, you may need different specialists to be involved in your product. That’s why you should check out in advance whether a company has all specialists: developers, testers, designers, finance experts, UI/ UX designers.

When you hire a dedicated team, you save plenty of time and effort. Otherwise, you’ll need to work with multiple specialists from different agencies to finalize your project.

Ask about risk mitigation plan

Fintech software development also hides many risks and different roadblocks. So it’s better to get ready for them beforehand.

Don’t omit this tip, and make sure the software development company has a risk mitigation plan to avoid conflicts. For example, a developed product is delivered with regulatory compliance and desired quality, etc.

​​Look at the team’s soft skills

In today’s fast-changing world, soft skills are essential for every member. Every team member should be willing to discuss and negotiate different issues. Otherwise, you may get a final adverse result.

Pay attention to the team’s flexibility, time management, problem-solving, and innovative thinking. Former clients might have already mentioned this information in their reviews. But also, you can ask the team directly about their vision of these factors.

One Last Thing

The primary advice is not to be afraid to hire a team of specialists who succeed in this niche and offer top-quality tech solutions, especially when you are aware of the top rating companies in the market.

One of the latest projects was an app built for the Space Needle, an observation tower in Seattle.

The Space Needle Official app is your companion as you explore everything there is to do at Seattle’s newly-renovated icon.

Our team used React Native to design cross-platform mobile solutions. We also integrated Augmented Reality into the React Native application. Although AR mainly uses Unity, we coded a native bridge with Swift, a programming language. So we could fulfill the primary task. Plus, we discussed all details with Apple, as we couldn’t upload an app to the App Store. The Space Needle app actively tracked geolocation data in the background, and the App Store blocked a release of the app. But our SPD Group’s team handled all challenges and provided everything on time.

Have a look at what you can get, choosing SPD Group services:

  • build applications for online banking, market data analytics, workflow automation, and other purposes;
  • develop and integrate secured payment systems according to PCI DSS and GDPR compliance;
  • introduce custom solutions like promotions, loyalty programs, and bonus cards;
  • create dynamic dashboards with supported report types for customers analytics and BI reporting; and
  • integrate AI-driven fraud detection systems.

Our team consists of certified specialists. We’ve all got our professionalism and expertise. But the most important — we want to share them and create bespoke successful products.
