Vertical SaaS vs horizontal SaaS: definitions, examples and economics
Vertical SaaS serves one industry, horizontal SaaS serves every industry. How each one sells and earns, with revenue mixes from public filings.
You are weighing a SaaS idea, a job offer or an investment, and someone calls the company “vertical SaaS” as if that settled the question. It tells you one thing: who the customer is. Vertical SaaS is built for one industry and tries to run most of that industry’s workflow. Horizontal SaaS does one job, such as email or accounting, for companies in every industry.
The label changes how a company finds customers, how big it can get and, often, where its money comes from. If you need the basic definition of SaaS first, read What is SaaS?. This guide assumes you know it and compares the two shapes, with numbers from two companies’ annual reports.
Vertical and horizontal in plain terms
Think of a general hardware store and a restaurant supply store. The hardware store sells hammers to plumbers, gardeners and office managers. The restaurant supply store sells only to kitchens, but it sells them almost everything: ovens, aprons, ticket printers, and sometimes the card terminal at the counter.
- Horizontal SaaS is the hardware store. It solves one function across industries: a CRM, a chat tool, a spreadsheet. Its buyer can be any company with that function.
- Vertical SaaS is the restaurant supply store. It solves many functions for one industry: a restaurant point of sale with menus, staff scheduling, online ordering and payments; or a construction tool with bids, drawings and site reports.
Neither is better. They are different bets on where to go deep.
How the economics differ
The table below compares the two models on the questions that decide how the business works. It is a generalization; individual companies cross the lines.
| Question | Horizontal SaaS | Vertical SaaS |
|---|---|---|
| Who buys | One department in any industry | The owner or operator in one industry |
| Market size | Very large, many competitors | Smaller, fewer direct competitors |
| How customers are found | Broad marketing, self-serve sign-up, partners | Trade shows, industry networks, referrals, field sales |
| Product depth | One job, done for everyone | Many jobs, done the way one industry works |
| Money beyond subscriptions | Usually small (services, add-ons) | Often large (payments, hardware, financing) |
The last row is the one that surprises people. A vertical product sits where the customer’s money moves: the restaurant’s card terminal, the clinic’s billing, the gym’s membership payments. Processing those payments can earn more than the software subscription itself.
Worked example: two revenue mixes from annual reports
Toast sells software and payments to restaurants, a vertical model. Salesforce sells CRM and related cloud software to companies in every industry, a horizontal model. Both publish their revenue by type.
Example: Toast’s revenue for the year ended December 31, 2025, from its Form 10-K, in millions of dollars:
| Revenue line | Amount | Share of total |
|---|---|---|
| Subscription services | $936 | 936 / 6,153 = 15.2% |
| Financial technology solutions (mostly payments) | $5,037 | 5,037 / 6,153 = 81.9% |
| Hardware and professional services | $180 | 180 / 6,153 = 2.9% |
| Total | $6,153 | 100% |
The three lines add up: 936 + 5,037 + 180 = 6,153. Only about one dollar in seven of Toast’s revenue is the software subscription.
Now the horizontal company. Salesforce reported total revenue of $41,525 million for fiscal 2026 (ended January 31, 2026), of which $39,388 million was subscription and support (Form 10-K). That is 39,388 / 41,525 = 94.9% subscription.
The two mixes are almost mirror images: 15% subscription at the vertical company, 95% at the horizontal one.
Why the revenue mix matters
Payments revenue is large but thin, because much of each card fee goes straight out again to card networks and processors. Toast’s results release for 2025 reported about $1.8 billion of GAAP gross profit from subscription services and financial technology solutions combined (Toast results release). Against $5,973 million of revenue from those two lines (936 + 5,037), that is a gross margin of roughly 1,800 / 5,973 = 30%.
A software subscription typically keeps a much larger share of each dollar, because the main cost is hosting and support, not money passed to a card network. So when you compare a vertical company with a horizontal one, compare gross profit, not revenue. A vertical company with $6 billion of revenue and a horizontal one with $2 billion can earn similar gross profit.
The other side of the trade is depth. Toast reported about 164,000 restaurant locations at the end of 2025 in the same release. Each one runs its orders and its payments through the product every day. That is why vertical companies often see customers stay for years: replacing the system means replacing the till, the menu and the payment terminal at once.
For how recurring revenue, gross margin and churn fit together in any SaaS business, see the SaaS business model.
Which one fits your situation
- If you are building: vertical is often easier to start, because you can name your first 100 customers and where they meet. The ceiling is the size of the industry, so check it before you commit. Horizontal starts harder, against many competitors, but the market has no single-industry ceiling.
- If you are buying: a vertical tool may replace three or four horizontal tools, with less integration work. You also depend on one vendor for more of your operations, and the pricing model may include a payments fee you must compare with your current processor.
- If you are investing or joining: read the revenue lines. “SaaS” on the label does not tell you whether most of the money comes from software or from payments.

Common mistakes
- Comparing revenue across the two models. Payments revenue carries a low margin, so a vertical company’s revenue overstates its software business. Why it happens: headlines quote revenue. Instead: compare gross profit and the subscription line, as in the example above.
- Calling any niche product “vertical”. A tool for one job in one industry, such as a dental appointment reminder, is a point solution. Why it happens: the industry is narrow, so the product feels vertical. Instead: ask whether it runs several of the industry’s core workflows.
- Dismissing vertical markets as too small. Toast’s restaurant-only model produced $6,153 million of revenue in 2025. Why it happens: one industry sounds like a niche. Instead: size the market by the money that flows through it, not only by the number of software seats.
- Assuming horizontal tools cannot serve an industry well. Many horizontal products sell industry templates and partner add-ons. Why it happens: the vertical vendor’s pitch says so. Instead: compare the specific workflows you need, side by side, on a trial.

In three sentences
Vertical SaaS runs many workflows for one industry, while horizontal SaaS runs one workflow for every industry. Vertical companies often earn most of their revenue from payments rather than subscriptions: in 2025, Toast’s subscription line was 15.2% of revenue, against 94.9% at Salesforce. Compare the two models on gross profit and the subscription line, because payments revenue is large but keeps a much smaller share of each dollar.
