An ISV, or independent software vendor, is a company that builds and sells software designed to run on another company’s hardware, operating system, or cloud platform. Unlike tech companies that manufacture devices or resell other vendors’ products, ISVs focus exclusively on creating their own software and licensing it to customers. The apps on your phone, the accounting tool your business uses, and the scheduling software at your dentist’s office were likely all built by ISVs.
How ISVs Differ From Other Tech Companies
The “independent” in ISV is the key distinction. An ISV develops and owns its own software, then distributes it through licensing agreements or subscriptions. This separates ISVs from several other types of technology businesses that might seem similar on the surface.
Original equipment manufacturers (OEMs) like Dell or HP build hardware and bundle software with it. System integrators take existing software products and customize or connect them for a specific client. Value-added resellers (VARs) purchase software from other vendors, add services or configurations, and resell the package. None of these companies are creating their own standalone software products the way an ISV does.
An ISV also differs from an in-house development team. When a bank builds custom software for its own internal operations, that’s not an ISV. The defining trait is that ISVs build software intended for external sale to other businesses or consumers.
What ISV Software Looks Like in Practice
ISVs build for two broad categories: horizontal markets and vertical markets. Horizontal software serves a wide range of industries. Think of project management tools, email marketing platforms, or payroll systems that work for nearly any type of business. Vertical software targets a specific industry, like electronic health records for medical practices, point-of-sale systems for restaurants, or case management tools for law firms.
Most modern ISVs deliver their products as software-as-a-service (SaaS), meaning customers access the application through a web browser or app and pay a recurring subscription fee rather than buying a one-time license. This model gives ISVs predictable revenue and lets them push updates to all customers simultaneously. Some ISVs still offer traditional on-premises software that customers install locally, though this approach has become less common outside of industries with strict data handling requirements.
How ISVs Make Money
The two dominant revenue models for ISVs are subscription pricing and perpetual licensing. With subscriptions, customers pay monthly or annually for continued access. Pricing often scales based on the number of users, the volume of data processed, or which features are included. A small business might pay $30 per month for a basic plan while an enterprise client pays thousands for premium features and dedicated support.
Perpetual licensing grants the customer a one-time right to use the software indefinitely, sometimes with an annual maintenance fee for updates and support. This was the standard model for decades and still exists in certain enterprise and specialized software markets.
Many ISVs also generate revenue through marketplace transactions. When an ISV lists its product on a platform like the Microsoft Azure Marketplace, AWS Marketplace, or Salesforce AppExchange, customers can discover and purchase the software directly through those storefronts. The platform typically takes a percentage of each sale in exchange for distribution, billing infrastructure, and access to its customer base.
The Role of Cloud Partner Programs
Major cloud providers actively recruit ISVs to build on their platforms because a rich library of compatible applications makes the platform more valuable to customers. To attract ISVs, these providers offer structured partner programs with technical and financial incentives.
Microsoft’s ISV Success program is a typical example. It’s a 12-month program that provides Azure credits, technical consultations, developer tools, early access to AI tools, and marketing support. To qualify, an ISV must be developing a business-to-business application that’s built on or integrated with Microsoft’s cloud, intended for repeat sales, and the company must commit to publishing the app on Microsoft’s marketplace within 12 months. AWS, Google Cloud, and Salesforce run similar programs with their own requirements and benefit tiers.
These partnerships are mutually beneficial. The ISV gets development resources, visibility in a massive marketplace, and co-selling opportunities with the platform’s own sales team. The cloud provider gets a broader ecosystem of applications that keeps customers locked into its platform.
Why ISVs Matter to Buyers
If you’re evaluating software for your business, understanding the ISV model helps you ask better questions. Because ISVs specialize in software development rather than hardware or consulting, they tend to iterate on their products faster and invest more heavily in the user experience of their specific application.
However, ISV software depends on the underlying platform it’s built for. A tool built for Microsoft 365 won’t necessarily work with Google Workspace. Before committing to an ISV’s product, confirm it’s compatible with your existing infrastructure. Check whether the ISV sells through a major cloud marketplace, since purchases made there often consolidate onto your existing cloud billing and may count toward any committed-spend agreements you have with that provider.
The subscription model also means your costs are ongoing. When comparing ISV products, look beyond the monthly sticker price and factor in what happens as you add users, need higher storage tiers, or require premium support. Many ISVs offer volume discounts or annual billing at a lower effective rate than month-to-month pricing.
ISVs as a Career and Business Path
For developers and entrepreneurs, launching an ISV has a lower barrier to entry than almost any other type of tech company. You don’t need to manufacture hardware or build your own data centers. Cloud platforms provide the infrastructure, and marketplace listings provide a distribution channel to millions of potential customers.
The tradeoff is competition. Because barriers are low, most software categories are crowded. Successful ISVs typically win by going deep into a specific vertical, solving a narrow problem better than anyone else, or building tight integrations with a platform ecosystem that make their product feel native to the tools customers already use.
