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]
The different types of software development firms can be categorized based on these parameters:
| Industry and field specialization | Platform and system type specialization |
|
|
Additionally, custom software development companies can be grouped based on their service types:
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:
A software development company’s workflow usually comprises the following stages [Kane Jason, Client Success Manager at Ace Infoway]:
Building software typically takes four to nine months. This timeline covers:
| Phase | Inclusions | Estimated timeline |
| Discovery | Documentation 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 |
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:
Depending on location, these agencies typically have a $20 to $200/hour rate. Here’s a breakdown by region:
| Region | Average hourly rate |
| North America | Up 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 expertise | Average 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 complexity | Average 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 feature | Estimated 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 project | Average 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 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 | |
| Pricing | Flexible | Fixed |
| Features |
|
|
| Designed for | Unique requirements by specific users | Purchase and access by anyone |
| Example | Banking services | Microsoft Office |
