Commercial software refers to software products that are developed, sold and distributed by companies or individuals for profit. It is also known as proprietary software or closed-source software. Some synonyms for commercial software would be for-profit software, privately owned software, licensed software, and non-open-source software. While commercial software may be more expensive than open-source software, the benefits include customer support, ongoing updates and maintenance, and compatibility with other proprietary applications. Additionally, some commercial software may be specifically tailored for certain industries or professions, such as accounting or graphic design, which can provide more specialized features and functionality than open-source alternatives.
