eCommerce Development Review from Jutamas Puengpinit
We engaged SoftLoft, Inc. to enhance our e-commerce platform, which is critical for delivering our modular IoT solutions efficiently across emerging markets. As Mandom Corporation (Thailand) Limited operates in a fast-paced production and tech environment, we needed a development team that could understand both our industry-specific needs and the technical depth required to support our operations. Our goal was to refine our platform's functionality, improve system stability, and enable easier configuration and ordering of IoT devices for clients.SoftLoft delivered far beyond our expectations. Their team, consisting of a Business Analyst, four Magento developers, and two testers, approached the project with remarkable professionalism. From the outset, the Business Analyst played a pivotal role in capturing our requirements in detail and transforming them into clearly defined tasks. This laid a strong foundation for the developers to implement complex features with precision, and for the QA team to conduct thorough, issue-free testing.The project involved building a new interface for configuring device packages, optimizing backend operations for better order management, and delivering detailed documentation to support ongoing maintenance. Every deliverable was executed with care, on time, and with full transparency.What stood out most was SoftLofts commitment to quality and their responsiveness. Communication was smooth and proactive throughout the project. Their attention to detail, flexibility in accommodating adjustments, and clear documentation ensured a seamless experience for our team. The improvements they implemented significantly reduced internal friction and enhanced client satisfaction.Our experience with SoftLoft was outstanding. They brought structure, clarity, and excellence to every phase of the project. We would highly recommend them to any business seeking a reliable and capable development partner for e-commerce solutions.

eCommerce Development Review from Lev Peysekhman
I had the pleasure of working with this development team on launching an eCommerce store for our healthcare retail business in Thailand. The project was complex building a Magento-based platform integrating over 10 different systems, including product and order management, plus financial tools. They also developed some really smart features, like a dynamic questionnaire that recommends vitamins based on user input, and a secure portal for doctors to manage prescription orders.What impressed me most was their professionalism and adaptability. We had a lot of stakeholders with varying needs, tight deadlines, and even changing regulations that required quick adjustments. Despite all this, the team remained agile, communicated clearly, and delivered exactly what was promised on time.Their technical expertise ensured seamless integration across all systems, which made the entire operation much smoother. Thanks to their work, we launched a fully functional store that improved customer experience and compliance with healthcare regulations. I highly recommend this team to anyone looking for a dependable, skilled partner for complex eCommerce projects.

eCommerce Development Review from Rob Duxter
I'm more than satisfied in my experiences with Soft Loft. I've worked with them for a few years now, on several projects from eCommerce sites (Magento, Shopify, custom) and even apps and information architecture requirements from tech stack evaluation/selection to DNS setup and management. Every team member I've engaged with from their Executives, to Business Analysts to Project Managers, QA and Developers or Information Architects .... total Pros. Whether a small project under $20k or large over $200k - the quality and professionalism is rock solid. Thank you Soft Loft. Keep it up!!

Cross-Platform App Development Company Hiring Guide
What is a cross-platform app development company?
A cross-platform app development company is a company that offers a seamless approach to mobile app creation. It goes beyond the traditional method of building separate apps for iOS and Android, opting instead for a single codebase that utilizes cross-platform frameworks like React Native or Flutter.
Businesses look for cross-platform mobile app development services because of these challenges:
- Low or declining brand visibility and sales
- App development using two code bases is slow and inefficient
- Updates are limited and slow to deploy
- Costly maintenance fees
- Limited app functionalities and features
With cross-platform app development companies, businesses can experience faster development times and potentially lower costs. Their framework experts ensure the app functions flawlessly on both iOS and Android devices, creating a flexible app that can reach a wider audience without the burden of maintaining separate codebases.
Success story
In the following success story chosen by our experts, we highlight how a cross-platform mobile app development company improves business efficiencies:
- Challenges: An American video rental company needed to upgrade its existing mobile app that was built with outdated coding practices, faced performance issues, and lacked device and orientation optimization. Its user interface (UI) was not intuitive, and it failed to load on a variety of devices.
- Solutions: Simpalm refactored the codebase, improving app performance and ensuring smooth operation on modern devices. Its new intuitive UI was now optimized for various devices and orientations. The team also integrated a proprietary AI engine alongside an off-the-shelf solution to create recommendation algorithms. These algorithms learn user behavior and suggest relevant content and deals, driving higher in-app purchases and monetization.
- Results: The collaboration improved the client’s mobile app. This resulted in increased user engagement, higher in-app purchases, and greater monetization for the client.
What do cross-platform app development companies do?

Success story
Cross-app development companies go beyond creating a seamless user experience (UX), as presented in the case study of Evolus and its partnership with Kingsmen Digital Ventures in creating an engaging app experience:
- Challenges: Evolus, a performance beauty company, struggled to enter the self-pay aesthetic market. The industry already had too many established giants, but its traditional communication methods could not grab user attention. It partnered with Kingsmen Digital Ventures to address the need for a customer-centric approach in the market.
- Solutions: Kingsmen Digital Ventures implemented a design and technologically driven approach to make Evolus stand out from the market. It prioritized user engagement and injected a playful, interactive tone throughout the user journey, along with fast-responding functionalities.
- Results: Within two quarters, Evolus rose to the #3 spot in market share. The app’s functionality translated to their ability to ship products to 3,500 accounts within 90 days. It has also fostered a user base that became active brand ambassadors. The platform’s engaging user experience led to referrals, propelling Evolus’ growth.
How much do cross-platform mobile app development services cost?
Cross-platform mobile app development services cost between $10,000 to $60,000 depending on the complexity of the app. Factors such as design, functionality, features, team size, and location of the team also affects the price of the cross-platform app development.
Here is a cost breakdown of cross-platform development app:
- Simple app development — $10,000 to over $30,000
Basic features such as login, user profile, in-app purchases, search - Moderate app development — $25,000 to over $45,000
Average features with additional inclusions such as social log-in and geo-tracking - Advanced app development — $40,000 and above
Complex features with longer timelines and custom design and system

On the other hand, 5.7% accept projects with a $50,000 minimum budget offering more complex services and features.
