SaaS and B2B: Two Different Questions About the Same Product

SaaS and B2B are often written together, which makes them sound like one idea. They are two. SaaS answers how the software reaches you. B2B answers who the customer is. Keeping them apart helps you read vendor claims and search the right way.

The two questions

• How is it delivered? If the vendor hosts it and you subscribe, it is software as a service. If you install it on your own equipment, it is not.
• Who is the customer? If a business buys it, it is business to business. If a person buys it for personal use, it is business to consumer.

The four combinations

1. B2B SaaS: a company subscribes to hosted software. Examples include project tools and accounting systems.
2. B2C SaaS: a person subscribes to hosted software for personal use, such as a photo or music service.
3. B2B installed software: a company buys software and runs it on its own servers.
4. Consumer installed software: a person installs a program on their own computer.

Many real products straddle the lines. A tool might have a personal plan and a business plan, or a hosted version and an installed version.

Why the distinction matters when you buy

For a business purchase, the contract, the data terms and the security review are usually heavier than for a personal one. If a vendor sells both, make sure you are looking at the business terms, not the personal ones. Business plans often add features such as shared accounts, central billing and administrator controls.

Why the distinction matters when you search

If you search for software "as a service" you will see hosted products. If you search for "business software" you will see products aimed at companies, hosted or not. Combining the terms, as in B2B SaaS, narrows the field to hosted products for businesses. If you do not find what you need, try dropping one of the terms.

Where the money differs

B2B products tend to be priced per user, per site or per volume, billed to a company, and often paid annually. B2C products tend to charge individuals monthly at lower amounts. The same vendor may price each side differently, because the cost of serving and supporting a business is different.

Common confusions

• Cloud versus SaaS. Cloud describes where something runs. SaaS describes a way of selling software. Not everything in the cloud is SaaS.
• B2B versus enterprise. Enterprise is about size. B2B is about customer type.
• Platform versus product. Either can be SaaS, and either can be B2B.

When the distinction is not useful

If you simply need a tool, label-matching is a distraction. Describe the job, and look at how the vendor handles pricing, support and data. The labels matter most when you are searching, writing about the market, or reading a contract.

Example: one accounting vendor, three labels

Take a company that sells accounting software. Its hosted version, used in a browser, is SaaS. Its installed version, for customers who must keep data on their own equipment, is not. Both are sold to businesses, so both are B2B. The same company also offers a simplified personal plan for freelancers who pay by card, which behaves more like B2C, even though freelancers run businesses of one.

Each variation changes the contract, the support, and the price. Anyone comparing the vendor against another needs to know which combination they are looking at. Asking "which version, hosted or installed, and which plan, business or personal?" clarifies most confusion before it starts.

Using the labels in your own writing

If you write about software for a website, a proposal or a report, choose the label that answers the reader's question. Use SaaS when the point is delivery, B2B when the point is the customer, and both together when you mean hosted software for companies. Avoid stacking labels for effect, since unusual phrases such as "B2B2C SaaS" are kept for situations that truly involve three parties.

Questions to ask when a vendor uses both labels

When a vendor describes its product as B2B SaaS, a few follow-up questions bring clarity. Is the product hosted by you for all customers, or can it be installed? Is pricing per user, per site or by volume? What differs between your business plan and a personal plan, if any? Where is business customer data kept, and what do you promise about it? The answers turn a label into a description you can compare with other vendors.

Examples of how the labels show up in searches

Someone searching for "SaaS" often wants a definition or a list of hosted tools. Someone searching for "B2B" often wants software or services for companies. Someone searching "B2B SaaS" wants hosted tools for business purposes. Vendors write pages to match these intentions, so a page's wording often says which kind of reader it expects. Notice the wording when you compare vendors. It tells you whom the vendor has in mind, and whether that is you.
