Custom Software Development Company Hiring Guide

What is a software development company?

A software development company is a service provider that specializes in building programs, systems, platforms, and other digital interfaces to help businesses improve workflows, boost productivity, and customize existing programs according to their needs. 

“Software development companies are the architects of innovation. They go beyond coding, addressing complex challenges, and crafting custom software solutions.  

These firms empower businesses to streamline operations, boost productivity, and stay competitive in a rapidly evolving landscape. In essence, a software development company is the driving force behind digital transformation, shaping the future of industry and enterprise.” [Kane Jason, Client Success Manager at Ace Infoway] 

What are the different types of software development firms?

The different types of software development firms can be categorized based on these parameters: 

Industry and field specialization Platform and system type specialization
  • Healthcare software companies
  • Education software companies
  • HR software companies 
  • Retail software companies 
  • Telecom software companies 
  • And more 
  • Web development companies
  • UI/UX development
  • Mobile development companies 
  • Enterprise software companies 
  • eCommerce development companies 
  • IoT development companies 
  • Artificial intelligence and machine learning specialized companies 
  • Cloud development  
  • Big data-specialized companies 
  • And more 

 

Additionally, custom software development companies can be grouped based on their service types: 

  • Staff augmentation or dedicated teams: They hire and manage teams of IT professionals dedicated exclusively to your organization, acting as an extension to its in-house team. This is typically a long-term partnership. 
  • Project-based development: These are often short-term, one-time partnerships that last until the successful delivery of the client’s project. 

What does a software development company do?

A software development company creates, improves, and maintains software solutions for a variety of purposes across a wide range of industries, users, and organizations. 

Software development companies conceptualize ideas and then create products that help brands improve workflows and optimize productivity. These products are usually referred to as “solutions” because they solve problems, ranging from the mundane and personal to the complex and professional. Software developers can also improve and personalize existing programs to meet an organization’s needs. 

Besides custom software development, software development agencies typically provide these services:  

  • Project management 
  • Consulting 
  • High-quality documentation 
  • Product development 
  • Software integration into other systems 
  • Data migration 
  • Big data and analytics 
  • DevOps 
  • Mobile app development 
  • Website development 
  • UI/UX design 
  • eCommerce development 
  • Specialized services 
  • Software testing and product quality assurance (QA)  
  • Troubleshooting  
  • Deployment 
  • Post-launch support 
  • Cloud software solutions 
  • And more 

A software development company’s workflow usually comprises the following stages [Kane Jason, Client Success Manager at Ace Infoway]:  

  1. Understanding clients’ needs in-depth 
  2. Crafting highly detailed and accurate blueprints 
  3. Writing custom code to build and customize software 
  4. Performing stringent testing to ensure product’s reliability  
  5. Giving constant customer feedback for further improvement 

How much time does it take to build software?

Building software typically takes four to nine months. This timeline covers: 

PhaseInclusionsEstimated timeline
DiscoveryDocumentation of requirements and design 2-4 weeks 
Planning, architecture & development Coding and framework construction 3-6 months 
Testing & compliance Coding review, end-to-end testing, and user acceptance testing (UAT) 3-6 weeks 

How much do top software development companies charge for their services?

The top software development companies can charge from $30,000 to over $300,000 for their services. 

The total cost of developing software depends on these factors: 

  • Level of expertise 
  • Third-party charges 
  • Project scope and complexity 
  • Number of platforms 
  • UI/UX design 
  • Technology stack 
  • Team size 
  • Location
  • Timeline 

Depending on location, these agencies typically have a $20 to $200/hour rate. Here’s a breakdown by region: 

RegionAverage hourly rate 
North AmericaUp to $200
Eastern Europe $22 to $38 
South Asia $18 to $25 

When it comes to the developer’s level of expertise, the hourly fee can be broken down further as follows:

Level of expertiseAverage hourly rate
Junior programmer $25 to $40 
Mid-developer $35 to $55 
Senior developer $45 to $70 

Based on the size and complexity of the project, software products might end up costing the following: 

Project complexityAverage project cost
Small apps$30,000 to $45,000 
Simple apps$40,000 to $120,000 
Large-scale apps$100,000+ 
Custom CRM software for small companies Up to $100,000 
Custom CRM software for startups $10,000 to $100,000 
Complex apps $200,000 to $300,000+ 

The more complex a project is, and the more developers are involved, the higher the expected cost. A small app that usually takes around 700 hours to develop comes at a lower price, while more complex software with server-side applications can have a six-figure price tag. 

Given a rate of $25 per hour, here’s a cost segmentation for a few key aspects of software development and their estimated time: 

Software featureEstimated project cost Number of hours 
Search$300 to $500 12-20 
Push notifications$625 to $875 25-35 
User login$750 to $1,125 30-45 
User profile editing$1,125 to $1,500 45-60 
Payment processing $1,500 to $1,875 60-75 
In-app calls $6,500 to $9,250 260-370 

As applications are essential in today’s business landscape, software development companies also offer mobile app development services. The cost of developing a custom mobile app varies greatly depending on the desired features.  

The average costs for app development are itemized as:  

App development projectAverage project cost
Minimum Viable Product (MVP) $5,000 to $20,000 
Simplified app $20,000 to $60,000 
Average-scale app $60,000 to $150,000 
Complex, full-scale mobile app $150,000+ 

“On average, software development budgets represent 4-6% of a company's total budget. Precise budgeting should align with the specific project's needs.” [Kane Jason, Client Success Manager at Ace Infoway] 

The top 50 software development agencies on DesignRush charge an average of $59/hour. Roughly 6.1% of software development companies on the platform have a minimum budget of less than $1,000, while 6% have a $50,000 minimum budget. 

What is the difference between custom software and commercial software?

The difference between custom and commercial software is that the former is specifically designed and developed for a particular user, while commercial software is pre-built and available for purchase and use by anyone. 

Here’s a breakdown of their differences and similarities: 

 Custom software Commercial software

  • Results-driven based on consumer needs and general market strategies 
  • Broad technical pool 
  • Easy installation 
Designed forUnique requirements by specific users Purchase and access by anyone 
ExampleBanking services Microsoft Office 

Why does your organization need custom software?

Your organization needs custom software especially when: 

  • Technology is leaving your brand behind: With competition monitoring, deep data gathering and analysis, and increased productivity via automation, customized solutions can help you stay ahead of other businesses. 
  • Your current software limits your work: If your current product isn’t doing its job properly, then it is time to let go of it, especially if it causes problems and slows you down. 
  • There is an increased necessity for manual work: If you already own off-the-shelf solutions that require manual workaround, you’re not maximizing your productivity. Customized solutions can automate manual processes. 
  • Reaching customers is getting tougher: If you find it difficult to reach and manage your customers, then it might be time for a technological upgrade. 
  • Your business is expanding: As your business grows, your software requirements will change, and off-the-shelf products may become too limiting. Customized solutions will scale with you. 

Why hire a custom software development company?

The main reason to hire a custom software development company is to obtain tailored solutions and leverage the latest technologies, allowing for scalability and seamless systems integration. 

Providing specialized skills, experience, and flexibility, software development companies are key partners to businesses that want to thrive in an ever-changing technology-driven business environment. 

Other reasons to partner with a specialized company are: 

  • Proven software development methodology 
  • More scalable solutions than off-the-shelf products 
  • Advanced management tools 
  • Dedicated technical support from experts  
  • Dedicated maintenance  
  • More robust cyber security measures 
  • Automation 
  • Integration between different departments within an organization 
  • Superior quality 
  • Timely completion 

Here's a case study that reinforces these reasons further. TradeSmith partnered with software development company Itransition to create a cutting-edge platform for effective portfolio management and stock market updates. 

Itransition launched the client's flagship investment management product, TradeStops, which gained a user base of 30,000+ traders and investors. Further demonstrating the benefits of hiring a top agency, TradeStops's total value of managed portfolios has exceeded $20 billion.
