SaaS companies deliver software over the internet instead of requiring customers to install and maintain traditional software on their own infrastructure. The model supports everything from customer relationship management and accounting to design, collaboration, cybersecurity, and project management.
For businesses, the attraction is straightforward: users can access applications through a browser or app while the provider manages much of the underlying infrastructure. The National Institute of Standards and Technology (NIST) defines Software as a Service as a cloud model in which customers use applications running on a cloud infrastructure without managing the underlying servers, operating systems, storage, or network.
What Are SaaS Companies?
SaaS companies build and operate software products that customers access as a service. Instead of purchasing a permanent software license and handling updates themselves, customers commonly pay through a subscription, although pricing models vary.
The provider typically takes responsibility for hosting, software updates, infrastructure, availability, and much of the technical maintenance. Customers generally manage their accounts, users, configurations, and the data they put into the application.
This creates a different relationship between software vendor and customer. The product is not simply sold once; the provider must continue delivering useful functionality, security, support, and a reliable user experience.
How the SaaS model works
A typical SaaS arrangement has four basic components:
- Cloud-hosted application: The software runs on infrastructure operated by the provider or its cloud partners.
- Internet access: Customers normally reach the application through a web browser, desktop application, mobile app, or API.
- Recurring commercial model: Customers may be charged per user, per month, by usage, by feature tier, or through another arrangement.
- Continuous service: Updates and improvements can be delivered without customers having to manage traditional software installation cycles.
NIST notes that SaaS usage can be billed according to factors such as users, time, bandwidth, executions, or stored data, depending on the service.
Major Types of SaaS Companies
The SaaS market covers a wide range of business functions. A company may focus on one specialized workflow or combine several products into a broader platform.
| SaaS category | Typical purpose | Example use |
|---|---|---|
| CRM | Manage customer relationships and sales activity | Leads, accounts, sales pipelines |
| Collaboration | Help teams communicate and work together | Messaging, meetings, shared documents |
| Project management | Organize tasks and projects | Planning, assignments, deadlines |
| Marketing | Automate and measure campaigns | Email, lead generation, analytics |
| Finance | Manage financial operations | Invoicing, accounting, expenses |
| Creative software | Create and edit digital content | Design, photography, video |
| Developer tools | Build and manage software | Code repositories, issue tracking, deployment |
The boundaries are not always strict. A platform may begin with one core function and expand into adjacent products, integrations, automation, analytics, or artificial intelligence.
For example, HubSpot offers marketing, sales, customer service, content, data, and revenue products around its customer platform. Atlassian provides cloud products such as Jira and Confluence that can be connected for project work and documentation.
Examples of SaaS Companies
Well-known software businesses illustrate how broad the model has become.
Microsoft operates subscription-based Microsoft 365, combining productivity applications, cloud storage, collaboration, security, and AI-related features depending on the plan.
Adobe offers Creative Cloud subscriptions that provide access to creative applications and related online services. Its current plans include products such as Photoshop, Illustrator, Premiere, and Acrobat.
HubSpot focuses heavily on customer-facing business functions, including marketing, sales, service, content, and data management.
These examples also show why defining SaaS only as “software you use in a browser” can be too narrow. Modern services may combine web applications, desktop software, mobile experiences, cloud storage, APIs, integrations, and automated services.
💡 Pro Tip: When evaluating a SaaS provider, test the workflow your team uses most often rather than judging the product by its feature list. A tool with fewer features can be more valuable if employees can adopt it quickly and use it consistently.
Why Businesses Use SaaS
The main advantage is reduced operational responsibility. A business does not necessarily need to purchase servers, deploy application updates, or maintain the software stack itself.
Other practical benefits include:
- Faster deployment: Users can often create accounts and begin configuring a service without a lengthy installation project.
- Flexible scaling: Subscription plans can frequently be adjusted as teams grow or requirements change.
- Remote accessibility: Internet-connected applications can support distributed teams and users working across locations.
- Automatic updates: Providers can release software changes centrally.
- Integration: Many services expose APIs or connectors that allow data to move between applications.
- Predictable budgeting: Subscription pricing can make software expenses easier to forecast, although costs can increase as usage expands.
However, SaaS is not automatically cheaper or simpler in every situation. A subscription can become expensive over many years, especially when an organization accumulates numerous applications with overlapping capabilities.
What to Check Before Choosing a SaaS Provider
The right product depends on the problem being solved, not simply on brand recognition or the number of features.
Start by defining the required workflow. Identify who will use the software, what data it will contain, which systems it needs to connect with, and what success should look like.
Then assess:
- Security and access controls: Review authentication, permissions, encryption practices, audit capabilities, and relevant security documentation.
- Data ownership and portability: Understand how you can export your information and what happens if you cancel.
- Reliability: Examine the provider’s published service commitments and incident history where available.
- Integration: Confirm that required APIs, connectors, and authentication options actually exist.
- Pricing: Calculate the expected cost at your current size and at a realistic future scale.
- Support: Check available support channels, response expectations, documentation, and training resources.
Security deserves particular attention because using SaaS changes the division of responsibility between the customer and provider. NIST has separate guidance addressing access-control considerations for SaaS, PaaS, and IaaS environments.
Common SaaS Mistakes
One common mistake is buying software before defining the business requirement. This can lead to unused features, duplicated subscriptions, and complicated workflows.
Another is overlooking exit planning. A company should know how its data can be exported, whether integrations depend on proprietary functionality, and how user access will be removed during a transition.
Teams should also avoid assuming that the provider handles every security responsibility. Account configuration, user permissions, authentication policies, data handling, and administrative practices can remain important customer responsibilities.
📌 Key Takeaway: SaaS works best when the service fits a clearly defined business process and the buyer evaluates more than features. Security, integrations, data portability, support, reliability, and long-term cost should all be part of the decision.
Frequently Asked Questions
What does SaaS stand for?
SaaS stands for Software as a Service. It is a cloud service model in which customers use a provider’s application without managing the underlying infrastructure. Applications are commonly accessed through browsers or other client interfaces, while the provider manages the core hosting environment.
How do SaaS companies make money?
Many use recurring subscription models, with prices based on users, features, usage, storage, or service tiers. Some combine subscriptions with usage-based charges, professional services, implementation fees, or other commercial arrangements. The exact model depends on the product and its target customers.
Is SaaS the same as cloud computing?
SaaS is one service model within cloud computing. NIST distinguishes SaaS from Platform as a Service (PaaS), which provides development and deployment capabilities, and Infrastructure as a Service (IaaS), which provides computing resources such as processing, storage, and networking.
What should a small business consider before buying SaaS?
A small business should examine total cost, ease of use, security, integrations, data export, customer support, user limits, and contract terms. It is also useful to test the product with the people who will actually use it before committing to a larger rollout.
Can SaaS be used by large enterprises?
Yes. SaaS can support organizations ranging from small businesses to large enterprises. Enterprise buyers may require additional controls such as centralized identity management, detailed permissions, audit capabilities, compliance documentation, integration support, and contractual service commitments.
Conclusion
SaaS companies have changed how organizations acquire and use business software by turning applications into continuously delivered services. The model can simplify deployment and maintenance, but it also creates new considerations around subscriptions, security, data portability, integrations, and vendor dependence.
For buyers, the most useful approach is to start with the business problem and evaluate the service against measurable requirements. A strong SaaS product is not simply one with many features; it is one that reliably solves an important problem while fitting the organization’s technical, financial, and operational needs.
