Here is a detailed blog to help you understand the software maintenance cost with factors affecting pricing for business needs, objectives, budget and preferences.
What is Software Maintenance?
Software maintenance refers to the process of changing, modifying, and updating software systems to resolve errors, adapt to trends, and improve performance. It caters to a variety of purposes, addressing any default bugs or errors before the software is launched. Being one of the integral parts of the software development life cycle, it has a core focus on eliminating errors and improving the development process to deploy secure products.
For instance, any retail ERP software requires compliance with GST updates, like changes in invoice format or tax slabs. It is a part of software maintenance where the developing team will modify a tax calculation module with integrated APIs and deploy a patch.
Mostly, software development aims to satisfy its users without any glitches. CTO or QA experts are required to focus on the software upkeep cost to address bottlenecks.
Key Factors that Affect Software Maintenance Cost
Developing team to look into estimating measure cost to maintain software, and it depends on multiple factors. From weak API documentation, outdated tech stack, to poor quality code, this can result in complex architecture and affect the software maintenance cost. Let’s take note of these factors and analyse how they influence software maintenance pricing.
Quality of Code
Poorly structured code might complicate the architecture and directly increase maintenance costs. So, developers spend more time comprehending logic and clean module code to reduce repetitive testing and debugging, to reduce long-term maintenance costs and longer development cycles.
Technology Stack
Using outdated and less-used technologies can add to maintenance costs due to limited access for skilled developers and tools. Modern stack offers better community support, debugging tools, and frequent updates that make software maintenance easier. Developing teams rely on a well-supported stack to reduce technical debt.
API Documentation
Insufficient documentation results in time wastage as developers apply reverse engineering before changes, and raise maintenance costs. Comprehensive documentation helps to ease software maintenance with easy identification and logic flows to improve efficiencies.
System Architecture
With poorly designed architecture, it becomes difficult to implement any modification, debugging and scaling for devices. Systems that are built with a scalability approach are cheaper to maintain, while bad architecture might increase complexities and maintenance costs.
Team Expertise
A development team with limited experience in software efficiencies and tech stack will find it difficult to maintain after-launch concerns and increase software maintenance costs. A skilled team can promptly resolve issues, write clean code, and prevent bugs at less cost through minimising downtime.
Software Testing
Manual testing is time-consuming, and there is a risk of human error that increases software maintenance costs. However, automated testing ensures safe and fast deployment that significantly reduces maintenance costs with prompt debugs and hotfixes.
Software Maintenance Cost Breakdown
Based on the industry norms, the average cost to maintain software can constitute 15% to 25% annually of the overall software development cost. Multiple factors affect the overall cost structure based on Software types and features integration. Here we are sharing the software maintenance cost breakdown and its core elements:

Different Types of Maintenance Plans
Software development has witnessed a major shift in terms of changing technology, process and deployment phases. Transforming from manual to automation, the development and QA teams are exploring multiple aspects of software maintenance rather than sticking to fixing bugs. Here are the following different types of maintenance plans and their importance:
Preventive Software Maintenance
This plan works to make any changes and adapt to the software so it can increase its longevity. A preventive approach might include optimising code, security audits, refactoring and updating documentation to prevent the deterioration of software.
Example: Amazon Web Services or AWS investing for preventive software maintenance with regular refactoring for code and it helps to improve scalability and security for Amazon platform.
Corrective Software Maintenance
This maintenance plan addresses the faults and errors within the software application that impact different parts, including logic, design and code. It helps to detect errors even before customers spot them and helps to save your brand reputation.
Example: Microsoft can invest in issuing regular Patch Tuesdays for fixing security bugs and flaws designed for Windows and Office products.
Adaptive Software Maintenance
It focuses on changing the environment for software, it can be in terms of hardware, software, cloud storage, and even operating systems. Adaptive software maintenance can reflect on policies and rules to modify for vendors or payment procedures.
Example: Netflix followed adaptive software maintenance to integrate updates like smart TV models, OS changes, or browser updates.
Perfective Software Maintenance
This focuses on changing requirements and features that exist with your software system. It can do anything adding as well as removing features, which helps for future enhancements to maintain software integrity and functionalities.
Example: Instagram uses it for the reel section, where frequent changes are required for features and improving UI/UX for stories based on user behaviour and competitive trends.
Hidden or Unexpected Maintenance Costs
Overlooking the proper mechanism for testing and maintenance factors might cause issues related to functionalities, unexpected errors, improper documentation and others. It turns up multiple hidden maintenance costs that expand the budget. Let’s discuss here:
API Changes
These costs are incurred when you take on external services like APIs or third-party libraries due to changes, elimination or depreciation. This can lead to additional maintenance costs for rewriting code, testing and redeployments.
Example: Payment gateways like Razorpay or PayPal require it to update changes for transactions.
Team Turnover
In case any core member of development and QA walks out of the team, this creates a burden of cost to find the right replacement and training for the code. It can slow down the fixes and the deployment of features.
Example: if any senior engineer leaves the organisation, it takes around 4 to 6 weeks to replace them, and it defers maintenance, causing more trouble.
Infrastructure Escalation
Many times, you design software based on your existing user base, and this might increase expenses due to hosting services, software tools, or scaling infrastructure. This comes with unexpected changes as not planned for your original budget.
Example: In case you reach the user limit or free features like GitHub action limits or AWS free bandwidth, you have to pay $400 per month extra for DevOps or cloud service.
Cost Comparison: In-house vs Outsourced Software Maintenance
Most companies are stuck on whether to choose in-house or outsource software maintenance, as both options have specific advantages. An in-house maintenance team can have better control, while outsourcing will be cost-effective. Here is the table for the cost breakdown for a comprehensive comparison:
| Cost Component | In-House (Annual in USD) | Outsourced (Annual in USD) |
