You have reviewed all the crucial information that will help you compare companies. With that in mind, your investment in the IoT creation will be profitable. Pay attention to these criteria which we followed when making a list of IoT product engineering firms, and you will see that the selection process is easy.
Further, you will read about opting for a vendor with well-defined stages that are battle-tested by a plethora of brands worldwide.
How to select an Internet of Things software development company?
To make a well-informed decision that can make or break your solution, you need to learn about the core steps to take when choosing a provider for IoT software development. Below, you will find the four phases of the selection process, described step-by-step for your convenience.
Check technical skills
According to the type of product you need, like remote asset monitoring or location tracking, you may need to find an IoT development company that excels in Artificial Intelligence for process automation, or can deliver enterprise-grade deployment.
Here are the skills to check and ensure the coders’ tech proficiency:
-
Programming languages: Python, JavaScript, Node.js, C, or C++.
- Cloud computing: AWS, Google Cloud, Azure.
- Networking: WebSockets and other protocols, TLS/SSL encryption.
- Frameworks: Django, .NET, Vue.js, Swift/Kotlin.
- Databases: MySQL, MongoDB.
The final choice of the tech stack will depend on your needs and common trends, for example, the MQTT protocol, which is chosen by 60% of respondents in Industrial IoT in the research. Below, you will find out how to check this tech compatibility efficiently.
Evaluate security
In the case of IoT solutions, you need to ensure the provider’s ability to handle the security of connected software and the device. From data encryption to authentication of end-users, every aspect has to be protected and monitored.
Let’s say that you need a solution for health monitoring, where you receive sensitive information, so Internet of Things software development companies will make every effort to avoid vulnerabilities like data stolen, unauthorized control over hardware, and so on.
You are able to check the portfolio of works we mentioned before, ensure that the cooperation will not lead to financial or reputation problems because they value security and follow cutting-edge practices.
Review client testimonials
Building trustworthy relationships with a provider starts with you checking the testimonials their previous clients posted online on various sources or even on their websites. These reviews will tell you if the firm has:
- social proof
- tech reliability
- strong communication
- balanced price and quality
- robust ongoing support
- your industry fit
For example, comparing IoT agencies, our experts paid attention to testimonials left by customers, evaluating pricing, fulfilling the needs of a business, values.
Consider post-launch support
IoT projects are typically long-term because these solutions are aimed at receiving continuous data-based insights and supporting scalability is vital. When selecting a supplier of IoT software development services, it is preferable to examine if they will not abandon you on the half of the way.
Now, as you already know what stands behind the selection of a provider, it is time to improve your comparison abilities and find out what you need to ask a firm to ensure that they are 100% your fit.
What to ask when choosing an IoT provider?
The selection of an Internet of Things software development company involves asking questions to ensure this vendor is the right choice. Our experts prepared a comprehensive list of queries for an initial interview that will help you to examine tech proficiency, communication, project planning, and support.
Tech expertise
Here, you are able to check more than just understanding of how the IoT works but real experience with the technology. We recommend paying attention to the last one, since your operation location will define regulations to follow, and you may need to work with a UK software company or one that understands the nitty-gritty behind compliance.
- Can you walk me through the past featured IoT project and describe the tech stack you used?
- Which communication protocols have you used and in what cases?
- Did you work with IoT cloud platforms (AWS IoT Core, Azure IoT Hub, Google Cloud IoT)?
- How do you ensure compliance with different regulations?
Project management
The quality of communication is vital as you will be cooperating for long term and have to remain on the same page.
- How will you estimate my project timeframes?
- What channels will you use to communicate with me and my team?
- How often will you update me about the progress of a product development?
Ongoing maintenance
Since you need to ensure that your software performs smoothly 24/7 and gather data effectively without delays, you need constant support from the vendor’s side.
- Do you provide maintenance after the launch stage?
- How do you react to emergencies, like downtimes or bugs?
- Will you handle features and security patches updates?
Armed with these questions, you are ready to choose the IoT software engineering company that 100% meets your needs. Further, it is time to define the trickiest point of comparing firms — the pricing approach, common rates, and more.
How much do IoT software development services cost?
The market size of IoT is higher than ever and it is only continuing to grow. We think that it is very important to have a full understanding of the corresponding pricing policy to become part of this sphere for years to come.
The prices of creating these specific goods depend on a variety of factors since the amount of funds you will put in would undoubtedly change based on the number of connected devices, depth of data processing, cloud infrastructure and security levels required.
For the agency, it isn’t just connecting codes to develop solutions; it’s also about seamless integration of hardware, real-time data transmission, and safeguarding sensitive information against theft and cyber attacks.
Small-scale projects may only dip their toes in basic connectivity, but large-scale implementations demand a whole new ball game of AI-driven analytics and strong defense protocols. Above all, understanding the difference in cost would determine whether the product could sail smoothly or land the company in stormy financial surprises.
|
Project scale |
Cost range |
Development time |
|
Small-sized IoT solutions |
$20,000 – $50,000 |
3 – 6 months |
|
Medium IoT deliverables |
$50,000 – $150,000 |
6 – 12 months |
|
Enterprise-grade software |
$150,000+ |
12+ months |
Finances have to be thought through well when investing in IoT in the same way as if you hire software developers, because the pricing can vary from simple applications costing small sums of money to huge thousands for locations of big, complex ecosystems.
However, the addition of advanced capabilities such as AI-driven analytics, predictive maintenance, and multiple-device synchronization at that time quickly pushed the budget into another territory.
Factors affecting IoT development costs
When looking for an IoT software development company and evaluating the budget, it is preferable to know what forms the final price. Here are the core factors:
- Type of connections. If you require Wi-Fi connectivity, it will have a lower impact, while Cellular, like 5G, is costly, and Bluetooth is lower in price.
- Infrastructure. If you select the cloud type, you have to consider paying for data storage, transferring, management, different integrations, and more.
- Project complexity. You may need a simpler system or an enterprise-level, like Audi connect®, which will cost more due to advanced features and connections.
- Customization. Off-the-shelf or pre-made products are cheaper but limited for adaptation to your needs. Tailored solutions mean building one from scratch.
Also, costs grow significantly when you add features like AI-driven analytics, predictive maintenance, multi-device sync, etc.
Typical budget ranges for different IoT solutions
When selecting an IoT software developer, it is advisable to know what budgets are common for different types of software. With the information below, you will be able to hire software programmers with a clear understanding of the price you can expect.
|
Type |
Description |
Average price |
