What is COTS (Commercial-Off-the-Shelf) Software?

Ever want to solve a business issue with a pre-packaged solution rather than constructing one from scratch? That’s where COTS (Commercial-Off-the-Shelf) software is used. Consider it as if you buy a smartphone—you don’t build the hardware yourself; you select a model that best meets your needs and get started immediately.

COTS software presents the same sort of convenience for companies. From managing inventory to processing transactions or operating customer service, COTS products provide pre-tested, established solutions that save time, money, and grief. Yet while it is a dream come true, deciding on the appropriate COTS product—and when not to—takes a little planning.

In fact, the total size of the software market, including COTS, was USD 730.70 billion in 2024, and this market is expected to grow at a CAGR of 11.3% during the projected period from 2025-2030.  

In this guide, we will explain everything about COTS software: what they are, their benefits, the implementation process and much more.

What is COTS software?

COTS software can be defined as software with existing capabilities, features, and functionalities, or a licensed solution, that needs no custom development nor ongoing maintenance. More specifically, software that is not to be written and maintained from scratch. In recent years, COTS software applications have significantly gained traction in popularity, primarily due to their economical and quicker viability.

COTS software is often viewed as a more practical option for the deployment of software systems by firms compared to custom software development (CS) and will come at a lower development time and lower cost and with expertise that is often lacking. COTS software can reach a large market across numerous industries or fulfill specific or specialized editions of industry or niche company growth solutions.

Commercial-Off-the-Shelf (COTS) software is a lexicon word used to succinctly convey an association with non-custom software, generally affiliated with ready-made applications, developed and sold in the open marketplace, or designed for general application to accommodate the typical needs of a firm. While COTS software applications have been recognized as an alternative to CS development routes, as it links the use directly with usability and eliminates much of heavy customization.

COTS software can be classified broadly into three types:

• General software applications: This includes software that can be used between business functions and industries, such as Microsoft Office, Adobe Creative Cloud, etc.

• Vertical Market Software: This is software written for a particular industry or market. Examples are medical billing software or retail inventory management systems.

• Horizontal Market Software: Horizontal market software applies to software that can be utilized across various industries but caters to a specific function within these industries, like CRM or HRM software.

Synonyms for the COTS definition are ‘off-the-shelf,’ ‘shrink-wrapped,’ or ‘boxed’ software. These all refer to the same phenomenon of pre-developed software that companies can buy and use without having to develop it custom.

• Modified Off-The-Shelf (MOTS): MOTS are software products or solutions intended for modification. They are essentially COTS products, although modifications are possible to satisfy specific requirements. This provides an even balance between the cheaper and more reliable COTS software and the flexibility of such custom-made software.
• Government Off-The-Shelf (GOTS): GOTS is government-produced software for the government. The benefit of GOTS is that it’s developed with the special needs of government agencies in mind. The downside is maintenance and upgrading GOTS can be costly, as it’s often accomplished by the government agency itself.
• Non-Off-The-Shelf (NOTS): The Department of Defense (DoD) in the United States uses these terms to refer to any items previously created for exclusive government use. NOTS may be acquired and utilized without additional development.

All of these different software types serve different purposes. Understanding what makes them distinct is important when making software decisions.

What is the Difference Between COTS and Custom Software?

All of these types of software will meet different needs, so it is important to understand their differences while making decisions regarding their acquisition.

Factor	Commercial-Off-the-Shelf (COTS) Software	Custom Software Development
Cost	Generally, COTS software offers a cost advantage as development costs are shared over many users.	Custom software, in general, tends to be expensive since the development costs are all allocated to just one organization.
Time	Since COTS software is already developed, time to implement is generally shorter.	Custom software uses considerable time for development and testing.
Customization	COTS software does offer various limited options of customizations targeted to a broader audience.	Customized software can be developed according to the specific requirements of individual businesses, allowing a larger degree of customization.
Maintenance	Most of the time, the maintenance is done by the vendor, which lightens the stress of the user.	Maintenance of generally developed custom software is usually the responsibility of the client who commissioned it, which can be resource-intensive.
Future-proofing	COTS software undergoes regular releases by the vendor and can thus always remain relevant with advancements in technology.	Custom software may become obsolete if not adequately and consistently updated. This can be an expensive and time-consuming process.

Benefits of Using Commercial-Off-the-Shelf Software (COTS)

Although commercial off-the-shelf software does not fit every organization or every purpose, there certainly are a number of advantages. Here are just a few points that highlight the benefits of COTS software:

• Cost-Effectiveness: Sharing the cost of developing COTS software with multiple users-it is generally cheaper than custom-built software and becomes suitable for many organizations at relatively small budgets.

• Time-Saving: There is no waiting time as required for custom development, and it largely fastens the pace of operations and overall efficiency because COTS software is pre-developed and ready to deploy by organizations.

• Ease of Maintenance: Among Other advantages of COTS software is that mostly the vendor is responsible for maintenance; thus, the end-user uses fewer resources and can allocate more time and energy to other important topics.

• Future-proof: Ongoing regular updates from the vendor would guarantee the continued evolution of COTS Software and ensure users have reliable and efficient software well into the future.

• Predictable Costs: COTS Software is most likely characterized by either a subscription or license fee; therefore, it is reasonable to see an organization’s ability to predict and plan for costs be improved over proprietary development and any hidden costs that may arise.

• Reduced Risk: The risk of failure becomes very low as projects are considered to have been effectively tested or proven by other users, lowering the risk of disruption due to bugs or flaws that could potentially hinder business functions.

• Standardization: COTS software consolidates by standardizing different systems and making the transfer and induction of new staff pretty easy; hence, more streamlined operations and productivity increase.

• Immediate Support: Vendors of COTS software generally offer immediate support to assist with any issues that arise, hence timely resolutions reducing possible downtimes.

Keep in mind that even with all of those positive aspects of COTS software, the decision of whether an organization should use COTS or develop a custom component is entirely dependent on the organization’s needs and available resources.
