What is the Difference Between Product as a Service and Software as a Service?
Product as a Service (PaaS) and Software as a Service (SaaS) are both subscription-based models, but they operate in different realms. Product as a Service focuses on delivering physical goods—such as vehicles, appliances, or industrial equipment—through a subscription or leasing model. The customer doesn’t own the product; instead, they pay for access or usage, and the provider maintains ownership, including responsibility for maintenance, repairs, and upgrades.
On the other hand, Software as a Service (SaaS) is a cloud-based service where users subscribe to access software applications over the internet. Instead of purchasing software outright and installing it on individual devices, SaaS allows customers to use the software remotely without worrying about maintenance, updates, or infrastructure management.
What is the Difference Between SaaS and SAAP?
SaaS (Software as a Service) refers to a software delivery model where applications are hosted in the cloud and accessed online through a subscription. Users don’t own the software but pay for its access and use as a service. Examples include Salesforce, Google Workspace, and Microsoft 365.
SAAP (Software as a Product), or Software as a Product, is a traditional model where software is sold as a one-time purchase, often installed on a user’s device. The customer owns the software and may need to manually update or upgrade it over time. Examples of SAAP include software like Adobe Photoshop (before it moved to a subscription model) or a Windows operating system license. The key difference is that with SaaS, the software is hosted and maintained by the provider, while in SAAP, the customer is responsible for updates and maintenance after purchase.
Is SaaS Considered a Product or Service?
SaaS is considered a service rather than a traditional product because it delivers software over the internet without transferring ownership to the customer. The user subscribes to access the service, and the provider handles all maintenance, updates, and data security. Unlike Software as a Product (SAAP), where the customer owns and controls the software, SaaS users benefit from ongoing support, access to new features, and automatic updates provided by the vendor.
What is the Difference Between SaaS and Software?
The main difference between SaaS and software lies in their delivery and ownership models. SaaS is a cloud-based service that users can access through a web browser or app, with all the software management handled by the provider. In contrast, traditional software (SAAP) is typically purchased as a one-time product, installed on a specific device, and managed by the user.
For example, Microsoft Office 365 is offered as SaaS, where users subscribe to access Word, Excel, and other tools. In comparison, the traditional Microsoft Office package was sold as a one-time purchase that users had to install and maintain on their devices.
Product as a Service vs Software as a Service: Examples
Product as a Service (PaaS) and Software as a Service (SaaS) can be found in different industries and use cases. Here are some examples:
Product as a Service Example: Philips Lighting offers “Light as a Service,” where businesses pay for lighting without owning the fixtures. Philips installs and maintains the lighting, ensuring efficient energy use and performance over time.
Software as a Service Example: Dropbox provides cloud storage as a service, allowing users to store and access files remotely. Users pay a subscription fee based on the storage capacity they need, without owning the underlying infrastructure.
In both models, the customer pays for usage or access but does not own the product or software, which is maintained by the provider.
Software as a Product Examples
In contrast to SaaS, Software as a Product (SAAP) involves purchasing and owning a software package. Here are a few examples:
Microsoft Windows: Sold as a one-time purchase, with users owning the operating system and responsible for installing updates.
Adobe Photoshop (before Creative Cloud): Users bought the software outright and installed it on their machines. Updates required a new purchase.
QuickBooks Desktop: Traditionally sold as software you purchase and install locally, users manage their financial data on their own system.
In these examples, the user maintains full control of the software, but with the added responsibility of updating and maintaining it.
SaaS vs Product-Based Companies
The key difference between SaaS companies and product-based companies lies in how they generate revenue and interact with customers. SaaS companies, such as Slack or Zendesk, offer digital solutions through a subscription-based model. Their focus is on delivering ongoing value through services like software updates, support, and new features.
Product-based companies, by contrast, rely on selling physical or digital products, often for a one-time fee. These companies include traditional manufacturers like Apple, which sells hardware like iPhones and MacBooks, or Microsoft, when it sold boxed software.
While SaaS companies generate consistent revenue through subscriptions, product-based companies often rely on new product launches and upgrades to maintain revenue streams.
What is Software as a Product?
Software as a Product (SAAP) refers to a traditional licensing model where users purchase and own the software. Once acquired, the customer installs it on their devices and is responsible for its maintenance and updates. Unlike SaaS, where the provider maintains continuous control over the software, SAAP gives customers full ownership. Examples of SAAP include legacy versions of Adobe Photoshop, AutoCAD, and Microsoft Office before these programs shifted to subscription models.

Is Software a Product or Service?
Software can be both a product and a service, depending on how it is delivered. When sold as a product, users purchase software outright and manage it themselves, such as traditional operating systems or graphic design programs. When sold as a service, such as in the case of SaaS, the software is delivered and maintained by the provider, and users access it via the cloud without needing to manage updates or installations.
Product vs Service
A product is a tangible or intangible good that customers purchase, own, and control, such as physical devices or standalone software. A service, on the other hand, is a process or function performed to meet customer needs, such as software access, maintenance, or support, without transferring ownership.
In the case of PaaS and SaaS, the distinction is clear:
PaaS (Product as a Service) delivers physical products like equipment or machinery under a subscription, focusing on access and maintenance.
SaaS (Software as a Service) delivers digital services through cloud-based applications, where users subscribe to access the functionality.
SaaP (Software as a Product)
SaaP (Software as a Product) is the traditional model of selling software as a one-time purchase. Customers own the software and are responsible for installing it, managing updates, and maintaining the system. Examples of SaaP include licensed game software, design tools, or accounting systems that are purchased and installed on local machines.
Software as a Solution
Software as a Solution refers to software designed to solve specific business or personal needs. This term is often used interchangeably with SaaS because SaaS delivers a comprehensive solution to a user’s problem (such as CRM, project management, or storage) through a service-based model. SaaS platforms like Asana, HubSpot, or Zoom provide specific solutions to organizational or personal challenges via cloud-based services, offering ease of use, scalability, and continuous updates.
