What is B2B SaaS?

B2B SaaS is short for business-to-business Software-as-a-Service. In the B2B SaaS industry, companies offer software products and services to other businesses on a subscription basis. This means that instead of purchasing a software license and owning the product, they pay a recurring fee to access and use the software.

The idea behind the B2B SaaS revenue model is to provide businesses with a cost-effective and efficient way to access the software they need without having to invest in expensive hardware or infrastructure. The vendor themselves handles maintenance, updates, and infrastructure. Businesses pay for what they use, which dramatically lowers total costs of ownership.

SaaS products are hosted on the cloud, which is what makes this software delivery model possible. Rather than downloading the software onto a computer, users can access it through an internet browser or mobile/desktop app. All their data is stored securely on remote servers, and updates are automatically provided by the vendor.

• Subscription software

The Meaning of B2B SaaS vs. B2C SaaS

There are two types of SaaS products: business-to-business (B2B) and business-to-consumer (B2C).

They both operate under the Software-as-a-Service model. But they differ significantly in several categories.

• Target audience — B2B SaaS targets teams or departments within a company, and the decision-making process typically involves multiple stakeholders, including IT professionals, executives, and end-users. B2C SaaS is aimed directly at individual consumers or end-users.
• Pricing models — B2B SaaS pricing is often based on the scale of usage, with tiered plans that can include factors like the number of users, the level of data usage, or the range of features they access. B2C SaaS prices are generally more straightforward and lower in cost, reflecting the individual consumer’s willingness to pay.
• Sales cycles — B2B sales are complex and take months to close, involving demonstrations, proposals, and negotiations. B2B sales are instantaneous (or close to it), with users able to sign up and start using the service immediately.
• Feature focus — Features in B2B software applications can be complex and robust because they’re designed to address specific business needs and workflows. They also require integration with other enterprise systems. In B2C, the focus is on user-friendliness, simplicity, and appeal to a broad audience.
• Implementation — Business software sometimes takes months to completely set up because it’s integrated with existing systems (which all need to share data) and customized for specific needs. B2C software is ready to use straight out of the box.

When you picture B2C SaaS, think of Netflix: Every customer sees the same home page, pays the same price, and accesses the same content.

To grasp the concept of B2B SaaS, think of Salesforce: Every organization’s workflows are customized to their exact needs, with different teams having different levels of access and functionality. Every Salesforce customer pays a different price than the next.

Growth of the B2B SaaS Industry

The concept of delivering software over the internet began in the 1960s with the advent of time-sharing systems, but the modern SaaS model didn’t take shape until the internet became widely accessible in the 1990s. Salesforce, founded in 1999, is credited with pioneering the B2B SaaS model with its CRM software.

The early 2000s witnessed the rapid expansion of SaaS and the subscription economy, driven by broader internet adoption and the increasing reliability of cloud services. Companies like Google and Microsoft began offering enterprise applications via the cloud, legitimizing SaaS for larger enterprises.

In the past decade, the adoption of cloud computing has skyrocketed, with SaaS becoming the default delivery model for many types of business software. In that time frame, subscription revenue has grown at 437%, outpacing the S&P 500 by 4.6x.

TL;DR: SaaS is huge in B2B, and it’s only getting bigger.

How it Works: B2B SaaS Application Technologies

There are a few core technologies driving the Software-as-a-Service model:

• The cloud
• APIs
• SDKs
• CI/CD
• DevOps

The Cloud

At its core, SaaS is cloud-based software. This means that instead of installing and running software on your local computer or server, you access it over the internet via a web browser or application. All the data processing and storage happens remotely on servers operated by a third-party provider.

Examples of cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. These providers offer a range of services such as infrastructure management, storage, networking, and databases.

This is what allows your product to be accessible 24/7 from anywhere in the world. Users don’t have to worry about physical servers, maintenance, or security at the infrastructure level. And SaaS product vendors get faster deployments, lower upfront costs, and easier expansion as their user bases grow.

APIs (Application Programming Interfaces)

APIs are your connectors. Think of them as “translators” that allow your application to “talk” to other software. They facilitate interoperability and data sharing between different applications and systems.

• CRM
• ERP
• Payment processors
• Marketing automation tools

Your customers are already using these tools. If your SaaS can integrate easily with them through an API-first approach, you’re giving your users ecosystem compatibility that extends far beyond your product.

In addition to eliminating data silos and making your product more valuable, APIs also enable you to build partnerships and integrations with other companies. This can lead to new business opportunities, increased customer satisfaction, and a stronger market presence.

SDKs (Software Development Kits)

While APIs expose functionality, SDKs give developers pre-packaged code, libraries, and tools to build on top of your platform faster.

A few examples:

• Amazon Web Services has an SDK for Java that enables developers to access their cloud infrastructure and services through Java code.
• Apple’s SDKs allow developers to build apps for iOS, macOS, tvOS, and watchOS with Xcode (Apple’s IDE). It includes the Swift programming language, a graphical interface builder, and debugging tools.
• The Salesforce SDK for iOS allows developers to build apps that integrate with the Salesforce Platform using Swift or Objective-C.

By providing an SDK, you’re making it easier for developers to build custom implementations or features on your platform and increase user adoption. This also means more opportunities for partnerships and integrations with other companies in your industry.

CI/CD (Continuous Integration / Continuous Deployment)

CI/CD is all about automating the software release process. Developers push updates, and with CI/CD pipelines, those updates can be automatically tested, built, and deployed (sometimes multiple times a day).

This reduces the time between code changes and deployment (which could otherwise take months), improving the speed of delivery and making it easier to ship bug fixes. For example, if you have a bug in your API, with CI/CD, you can quickly identify the problem and deploy a fix without disrupting your entire system.

DevOps

DevOps is the culture and practice that brings everything above together. It’s about breaking down silos between development and operations teams.

In a traditional setup, developers write the code, and ops teams figure out how to deploy and run it. DevOps says, “Let’s collaborate from day one.”

The result? Higher velocity, greater stability, and a team that’s aligned around delivering value quickly and reliably.

Other Tools and Resources for SaaS Apps

Depending on how complex your SaaS architecture is, there are a few more foundational pieces you might have to consider:

• Containerization and orchestration: Patforms like Docker and Kubernetes let you package software in a way that’s consistent across environments and scale it with precision. This is especially useful for complex SaaS architectures.
• Monitoring and observability: Tools like Datadog, New Relic, or Grafana help you see what’s going on inside your system, which is critical for uptime and proactive issue resolution.
• Authentication and authorization: Tools like OAuth and SAML matter in B2B SaaS because clients expect enterprise-grade user management and data security.
• Infrastructure as code (IaC): Tools like Terraform and AWS CloudFormation let you manage your computing infrastructure (e.g., operating systems, storage, database connections) through code instead of manual configuration, making it easier to maintain and replicate.

Types of B2B SaaS Products and Examples

These days, it’s impossible to list all the different types of business software available to B2B companies. Everything from the Chrome plugin you use for help with sales prospecting to the massive database you use to manage your customer data is a SaaS app.

Broadly speaking, we can categorize them based on their architecture, functionality, and the market they serve.

Multi-Tenant SaaS Applications

In a multi-tenant architecture, a single instance of the software application serves multiple tenants (i.e., users). Each tenant’s data is isolated and remains invisible to other tenants, yet the infrastructure and software code are shared.

This model offers cost efficiency, simplified maintenance, and virtually limitless scalability since all users are on the same infrastructure and software version. In fact, the vast majority of your favorite SaaS tools are almost certainly multi-tenant:

• DealHub
• DocuSign
• Dropbox
• Google Apps
• HubSpot
• Mailchimp
• Salesforce
• Zendesk
• Zoom

…to name a few.

Single-Tenant SaaS Applications

Single-tenant architecture provides each customer with a dedicated instance of the software, along with the underlying infrastructure. This can offer enhanced security, greater customization, and more control over the deployment environment.

It’s far less common than multi-tenancy (to be a true cloud app, it has to be multi-tenant). Microsoft Word, which lives on each user’s local device, is an example of single tenancy.

Microservices

Microservice architecture structures an application as a collection of loosely coupled services, which implement business capabilities. Taking a modular approach enables customers to build a composite application that combines only the services they need.

As an example, DealHub users might only use DealHub CPQ. If they need more than a quoting tool, they can use DealRoom and DealHub Billing for a completely integrated quote-to-revenue process.

Vertical SaaS

Vertical SaaS is tailored for specific industries or sectors, incorporating industry-specific features and compliance standards. It caters to niche markets with particular needs.

For example:

• Clio targets legal firms with its practice management software
• Infor Hospitality is built for hotels and restaurants
• Replicon helps professional services firms with time tracking and billing
• Zillow serves the real estate industry with its property management platform

These solutions deeply integrate into industry workflows. They offer more specialized tools and data models that reflect industry practices, but companies outside their ICP probably won’t see much value in them.

Horizontal SaaS

Horizontal SaaS is designed to be used across multiple industries or business sectors, focusing on broad functions. Think of horizontal SaaS as general-purpose tools, such as:

• Dropbox for file storage
• HubSpot for marketing automation
• Mailchimp for email marketing
• Salesforce for CRM
• Slack for collaboration
• Trello for project management

Horizontal SaaS products aim for a wide market base, addressing common needs that are not specific to any single industry. They may, however, offer customizations and microservices that make them suitable for some niche markets.

Sales and Marketing SaaS

SaaS apps focused on sales and marketing processes help businesses manage their marketing strategy, sales pipeline, and customer relationships. They offer tools for data analysis, customer tracking, and automation of sales and marketing processes.

Examples include:

• CRM (customer relationship management)
• CPQ (configure, price, quote)
• Sales enablement
• Sales engagement platforms
• Email marketing
• Marketing automation
• Social media management
• Contract management

Data and Analytics SaaS

You’ll use data and analytics platforms to gain insights into your user experience, customer journey, and business performance. These tools often require integrations with other apps to collect data from multiple sources.

Examples include:

• Data visualization tools
• Data warehousing
• Customer data platforms (CDPs)
• Business intelligence apps
• Web analytics (e.g., Google Analytics)
• A/B testing solutions

You’ll connect your data platforms to your day-to-day business software to measure and analyze data, understand your user’s behavior, and make data-driven decisions.

Finance and Accounting SaaS

These apps help businesses manage their finances, accounting processes, invoicing workflows, and financial reporting.

Examples include:

• Billing and invoicing systems
• Accounting and payroll software
• Expense tracking tools
• Enterprise resource planning (ERP)
• Financial forecasting tools
• Tax prep software

You will integrate these with your sales software to create an end-to-end sales workflow, automate billing and accounting processes, and track sales performance. For instance, you can have your CRM automatically update a customer’s profile when they make a payment or log an expense.

Collaboration Software

Cloud-based collaboration software helps teams work together more productively, remotely or in person. It makes communication and information sharing easier, whether that’s messaging, video conferencing, or collaborative project management.

Examples include:

• Web conferencing
• Messaging
• Project management
• Knowledge management
• Document collaboration and file sharing
• Industry- or role-specific tools (e.g., Figma for design teams)

Collaboration apps are especially valuable in remote work setups, where teams are distributed and have limited opportunities for face-to-face interaction.

Artificial Intelligence Applications

AI is one area of software that has permeated B2B companies across different industries. It leverages algorithms to help companies make more informed decisions and automate processes.

Examples include:

• Virtual assistants
• Generative AI
• Natural language processing (NLP)
• Predictive analytics
• AI-driven customer service (e.g., chatbots)
• Sales AI

Most of the abovementioned SaaS applications also incorporate AI capabilities. For instance, most CPQ software features pricing automation, dynamic product suggestions, and lead scoring.

B2B SaaS Pricing Models

Simple SaaS solutions might offer a flat subscription fee for unlimited use of the software. However, most software companies have more complex pricing models based on usage, number of users, and features.

Here’s a brief rundown of different SaaS pricing models:

• Freemium — Offers free access to a basic version of the software, with limited features or usage, while charging for more advanced features.
• Flat-rate pricing — A fixed subscription fee for unlimited access to the software or specific features.
• Usage-based pricing — Charges based on the amount of usage or data consumed.
• Per-user pricing — Based on the number of users accessing the software, often with tiered pricing for different levels of access.
• Tiered pricing — Different tiers or packages with varying features and prices to appeal to a wider market.
• Value-based pricing  — Pricing based on the value or ROI the software provides to the customer.
• Enterprise SaaS pricing — Tailored pricing for your largest customers, based on their unique needs and usage patterns.

In general, SaaS business models entail multiple layers of pricing. You might charge a flat rate for each subscription tier with up to X users on the account, then charge an extra $Y/month for each additional user. For enterprise companies, you’ll offer sales consultations and personalized quotes.

Benefits of B2B SaaS Products

Compared to on-prem software (or worse, manual processes), cloud-based SaaS apps provide various benefits for businesses, including:

• Significantly lower upfront and ongoing IT costs
• Upward and downward scalability with changing business needs
• Accessibility from any location or device
• Seamless integration with other tools via microservices and APIs
• Continuous access to the latest features.
• Robust security measures.
• Advanced analytics for better decision-making.
• Easy team collaboration and communication.
• Customizability for your specific workflows

Measuring Success: Key B2B SaaS KPIs

To understand how your business is performing, you have to look at SaaS metrics. There are too many to count, but here are the most important:

• Customer acquisition cost (CAC) — The average cost of landing one new customer, from initial awareness through deal closure.
• Customer lifetime value (CLV) — The total revenue that customer brings in over the whole time they’re with you.
• Monthly recurring revenue (MRR) — Revenue you can expect to earn each month from your active customers (best for short-term analysis).
• Annual recurring revenue (ARR) — A similar metric to MRR, but measured over a full year (to zoom out over the long term).
• SaaS churn rate — The percentage of customers that stop using your software in a given period.
• Net Promoter Score (NPS) — A measure of customer satisfaction and loyalty, based on how likely they are to recommend your product.
• Customer acquisition rate — The number of new customers brought on in a given period.
• User engagement — e.g., active users, feature adoption, time to value

Common Challenges Facing B2B SaaS Companies

The B2B SaaS sector faces several key challenges in 2025, reflecting the industry’s dynamic nature and rapid technological evolution.

• Rising operational costs
• Intensifying competition
• Double-focus on retention and acquisition

And organizations worldwide use an average of 130 software applications each.

Selecting a SaaS Solution for Your Business

To pick the right SaaS app for your business, there’s a specific framework you need to follow, along with some important evaluation criteria and best practices.

Here are six steps to choosing a solution that will meet your organization’s specific needs:

1. Evaluate your business needs and objectives.

Before diving into tools and vendors, take a step back: What exactly are you trying to solve or improve?

Is it streamlining operations? Automating manual tasks? Enhancing customer communication?

Write down your top 3–5 business priorities. Then ask:

• What processes are slowing us down?
• Where are we losing time or money?
• What do we need to scale?

Clarity is what gives you a focused lens when evaluating tools.

2. Evaluate the most important factors.

You’re not looking for the flashiest SaaS, you’re looking for the one that solves your specific problems. Once you know what you need, start matching those needs to features.

• Ease of integration (will it work with your current stack?)
• User experience (can your team adopt it quickly?)
• Customization options (can it flex to fit your workflow?)
• Analytics and reporting (can it give you actionable insights?)
• Security features (especially for customer data)

Make a “must-have” vs. “nice-to-have” list. That way, you stay anchored when features start piling up.

For your business, say you’re managing multiple teams or clients remotely. Then, you’d want features like role-based access, cloud-based dashboards, and automated reporting.

3. Evaluate each vendor’s reliability and support.

When you sign up, you’re entering into a relationship with the vendor. Costs of implementation (and switching) are sizable, so it’s important to make the right decision on who to “partner” with the first time.

Look for:

• Track record (How long have they been around? Do they have strong case studies or references?)
• Customer support quality (Do they offer 24/7 support? Chat? Phone?)
• Product roadmap (Are they innovating or stagnant?)
• Service Level Agreements (SLAs) and entitlements (What uptime are they guaranteeing?)

Also ask yourself: If this platform has issues, how fast can I get help?

If a SaaS tool goes down, does that stall your client deliveries? Impact your revenue? Choose a vendor who treats support as seriously as you treat your customers.

4. Look closely at the pricing structure.

Some SaaS platforms charge per user, others per feature, some scale with usage. Some do all of the above.

Look beyond the sticker price. Ask:

• What’s the total cost of ownership over 12–24 months?
• Are there onboarding or training costs?
• Are there usage caps or overage fees?
• Can you downgrade if needed?

And consider scalability — does the pricing still make sense if you double your team or customer base? You might find there’s a better solution for scaled growth that’s less expensive in the long run.

5. Start with a free trial or POC.

A good trial or POC (proof of concept) lets you test drive the actual experience. During the trial, focus on answering these questions:

• Is it intuitive for your team?
• Are there roadblocks or confusing UX issues?
• How responsive is support during this phase?
• Does it actually save you time or just add another layer?

You can even set up a mini project or task inside the platform during the trial. That gives you a real-world sense of how it’ll perform in your business.

6. Make the final decision.

This is where you evaluate the full picture—features, pricing, support, scalability, team feedback. Create a short scorecard if you want to make it more objective.

Also, think long-term:

• Is this tool built to evolve with my business?
• Will this vendor still be around (and innovating) in 2–3 years?

From the very beginning involve your team (especially end users). Get their feedback and take inventory of how quickly they’ll be able to fully adopt the solution.
