Introduction to SaaS
When exploring technology solutions for your business, you will often encounter SaaS companies. These organisations have revolutionised how businesses access software, making powerful tools available online without complex installations. In this guide, we’ll explain what SaaS is, explore the SaaS meaning in a business context and show what SaaS companies do. We will also, look at how custom-built software can transform operations or even become a product your company can license to other businesses.
Whether you want to improve your internal systems or create a software product for customers, this post will help you understand the essentials of SaaS.
What Is SaaS? Understanding the SaaS Meaning
Traditionally, businesses bought software and installed it directly onto their computers. Most of this software came with single licences, meaning several copies had to be purchased so every member of staff could use it. Common examples include Microsoft Word, Excel, Adobe Photoshop, and accounting tools such as Sage.
This type of software had to be installed manually on each device, and updates also needed to be carried out by hand. Because of this, companies usually needed either an IT department or at least one person with technical knowledge. Sharing files or working together could also be slow and awkward, especially when staff were based in different locations or using different versions of the same software.
SaaS stands for Software as a Service. Instead of buying software, you access it through an internet browser. Your software and data will be stored and accessible live in the cloud. The cloud is a network of remote servers that store information online instead of on your computer. If you want to learn more about the cloud and how it works, see our guide to cloud computing.
Think of SaaS as renting software rather than owning it. SaaS providers manage the underlying infrastructure, ensuring your system remains reliable and up to date. You can log in from anywhere, whether that’s your office, home, or on the move. For example, instead of installing accounting software on each computer, your whole team can access the same system online, enter invoices, and view reports instantly, no matter where they are.
SaaS Subscriptions
The SaaS meaning today goes beyond just saving money. It allows businesses to work more flexibly, collaborate more easily, and access tools quickly. Most SaaS products operate on a subscription basis, which may be per user, per company, or groups of users. This flexibility allows you to control costs and scale as needed.
Here is an example of typical per-user subscription tiers based on team size:
| Users | Monthly Cost per User | Notes |
|---|---|---|
| 1 to 5 | £25 | Suitable for very small teams or start-ups. |
| 6 to 20 | £22 | Slight discount for growing teams. |
| 21 to 50 | £20 | Larger teams get volume pricing. |
| Above 51 | £18 | Enterprise pricing for large organisations. |
This shows how businesses can choose the pricing plan that best suits their size and needs, helping to avoid large upfront costs while scaling the software usage efficiently. For instance, a start-up with three employees would pay £25 per user per month, while a mid-sized company with 30 users could pay £600 per month at £20 per user.
How SaaS Companies Work
Much of this has been mentioned in the previous section, but to summarise, SaaS companies create, host, and maintain software that runs online. Customers pay a monthly or yearly fee to use the service, which they can access from any device with a browser or mobile app. Because everything is managed in the cloud, there’s no need to install or update the software yourself.
Behind the scenes, SaaS providers look after servers, security, and updates, so you can focus on running your business instead of worrying about IT issues.
Most SaaS tools offer several pricing tiers, allowing you to start small and upgrade as your business grows. This flexible approach means you only pay for what you need, avoiding large upfront costs.
Examples of SaaS Companies
You are likely already using SaaS without realising it. Some familiar examples include:
- 💬 Slack – A communication tool for teams to chat, share files, and manage projects.
- 📊 Salesforce – A customer relationship management (CRM) platform for tracking sales, customers, and marketing campaigns.
- 📈 QuickBooks Online – Accounting software for invoices, payroll, and expenses.
- 💼 Microsoft 365 – Cloud-based Word, Excel, and Outlook accessible anywhere.
- 🛒 Shopify – eCommerce platform enabling businesses to sell online.
These examples show the range of SaaS companies, and the different business needs they serve; from communication and marketing to finance and sales.
Why SaaS is so Popular Among Businesses
SaaS is popular because it is accessible, flexible, and easy to manage. Companies can get started quickly without installing software or buying expensive servers. Updates happen automatically, and the service scales as your business grows. Beyond these basic advantages, SaaS also supports collaboration, cost control, and rapid deployment.
Work from Anywhere
Because SaaS runs online, your team can log in wherever they are, in the office, at home, or on the move. All that’s needed is an internet connection, this makes teamwork and communication much easier.
Always Up to Date
You don’t have to worry about installing updates or patches. SaaS providers handle everything in the background, so you’re always using the latest version with the newest features.
Scalable Solutions
You can start small and grow over time. Add users, features, or integrations as your business expands. Subscription plans make it easier to manage costs while scaling. For example, a start-up might begin with a basic plan for five users and gradually upgrade as their team grows.
Reduced IT Costs
Since servers and infrastructure are managed by the SaaS provider, businesses save money on hardware, IT staff, and maintenance. This makes SaaS particularly cost-effective for small to medium-sized enterprises.
Data Protection and Backup
Data is backed up in the cloud, reducing the risk of lost files due to device failure or accidental deletion. Employees can switch devices without losing work, which is ideal for flexible working arrangements.
Rapid Deployment
SaaS can be set up quickly, often within hours. This is much faster than traditional software installations, which may require days or weeks of setup, configuration, and testing.
Challenges of SaaS
While SaaS offers many advantages, there are some considerations:
Dependence on Internet
A stable connection is essential. Some SaaS tools include offline functionality, but internet outages can temporarily disrupt access.
Data Security
Data stored in the cloud requires robust security. When using or developing SaaS, it’s not only about keeping data safe, but also about following the right laws and standards. Businesses must make sure their SaaS providers comply with rules such as the UK GDPR, ISO 27001, or SOC 2.
Limited Customisation
Off-the-shelf SaaS may not fit every business process perfectly. Features are designed for general use rather than specific company workflows.
Ongoing Subscription Costs
Although SaaS reduces upfront costs, monthly or yearly fees can add up, particularly for large teams or premium plans.
Most modern SaaS platforms address these challenges with secure infrastructure, offline options, and flexible plans, making them reliable for everyday business operations.
Custom Software: Built Around Your Business
Sometimes generic SaaS (general SaaS products built for a specific purpose or for an individual industry sector) simply isn’t the right fit. When a company has very specific processes, unusual requirements, or operates in a niche industry, custom software can be the best solution. Custom software is built from the ground up to match the exact way your business works, rather than forcing your team to work around generic tools.
How Custom Software Differs from Standard SaaS
Custom software is designed entirely for your organisation. It fits your workflows, mirrors your branding, and can link to any existing systems you already use. Unlike pre-made software, you decide what features are included, how the system grows, and how updates are handled.
For example, a care provider might need a unique rota system connected to patient records and compliance checks. Off-the-shelf tools might cover only part of this process, but custom software can pull everything into one simple platform.
Building With Growth and Revenue in Mind
If your business works within a niche industry, custom software can offer even more value. When your system solves a problem that others in your field also face, you may choose to license the software to other companies. This can bring in a new income stream and help you get a better return on your investment (ROI).
The software can be designed from day one with licensing in mind. This includes:
- Secure hosting and maintenance plans
- Multi-tenant architecture so each customer has their own secure space
- User management to control access
- Flexible features that can be turned on or off depending on the client’s needs
- Branding options for different companies
This means you not only create software that improves your business internally, but you also build a product that can generate long-term profit.

Choosing Between Off-the-Shelf SaaS and Custom Software
Every business has different needs, so the right choice depends on what you want the software to achieve. Sometimes a ready-made SaaS product is ideal. In other cases, a fully custom-built system is the better long-term option.
Below is a helpful comparison:
| Option | Best When… | Pros | Cons |
|---|---|---|---|
| Off-the-Shelf | You need general tools like email, file storage, accounts, or scheduling. | Quick to set up, low upfront cost, regular automatic updates. | Limited customisation, may not fit unique processes, subscription fees can add up. |
| Custom Software | Your business has unique workflows or you operate in a niche sector. | Designed around your needs, stronger integration, can scale with your business, can be licensed to others. | Higher initial cost, longer development time. |
| A Mixed Approach | You want the best of both worlds. | Use standard SaaS for everyday tasks and custom software for specialised needs. | Requires planning to ensure everything works together well. |
When choosing, think about:
- How unique your processes are
- Whether off-the-shelf tools can truly support your work
- Long-term value, not just the upfront costs
- Your security and compliance needs
- Future plans, including possible growth or licensing
This approach ensures you choose software that genuinely supports your business both now and in the future.
Measuring SaaS Success: Key Metrics to Track
If your business is thinking about creating or selling a SaaS product, it’s important to track certain performance measures. These metrics help you understand how well your software is performing and how your business is growing:
- 💰 Monthly Recurring Revenue (MRR) – The total predictable income your SaaS generates each month from subscriptions.
- 📉 Churn Rate – The percentage of customers who cancel or stop using your service. A lower churn rate means happier customers.
- 💡 Customer Acquisition Cost (CAC) – How much you spend on sales and marketing to gain each new customer.
- 📈 Customer Lifetime Value (LTV) – The total income you can expect from a customer during their time using your product.
- ⚙️ Active Users – The number of people who regularly use your software, which shows how valuable and engaging it is.
By keeping an eye on these figures, you can make better decisions about pricing, marketing, and product development, ensuring your SaaS remains profitable and sustainable.
The Future of SaaS
Cloud software continues to grow in popularity, especially as more businesses rely on remote working and digital tools. Companies now expect software that is:
- Flexible and able to scale as they expand
- Easy to use without needing much IT support
- Accessible from any device, wherever staff are working
- Secure and reliable
As these expectations rise, the SaaS industry must keep adapting to meet modern needs. New technologies, changes in working habits, and the demand for faster, smarter tools are shaping the direction of cloud software. This sets the stage for several key trends that are becoming increasingly important for businesses of all sizes.
Emerging Trends in SaaS
The SaaS industry keeps changing as new technologies and working styles appear. Here are some of the key trends shaping the future of cloud software:
Artificial Intelligence (AI) and Automation
Many SaaS tools now use AI to improve efficiency, analyse data, and automate everyday tasks. For example, AI can help predict sales trends, spot customer behaviour patterns, or speed up customer support.
Sustainability and Energy Efficiency
Cloud providers are focusing more on reducing energy use and running data centres in an environmentally friendly way.
Low-Code and No-Code Platforms
These tools allow people with little or no coding experience to build and adapt applications quickly. Businesses can create simple systems or workflows without needing a full development team.
Vertical SaaS
Instead of general-purpose tools, many providers now create software designed for specific industries, such as healthcare, logistics, or construction. This means more specialised features that fit industry needs.
Mobile-First Design
As more people work on the go, SaaS companies are making sure their products are easy to use on phones and tablets as well as desktop computers.
These trends show that SaaS continues to evolve, offering smarter, more accessible, and more responsible solutions for businesses of all sizes.
