Which one-person businesses have the best margins now?

Why can one-person businesses keep so much more money now?

The best one-person businesses can keep unusually high margins today because one founder can automate work that used to require several employees.

Software has always been cheap to reproduce. What has changed is everything surrounding it. A founder can build with coding assistants, automate billing and onboarding, outsource tax handling to payment platforms, answer routine support questions automatically and run infrastructure without a dedicated operations person.

Photo AI gives us a useful real-world benchmark. Its founder Pieter Levels disclosed that the one-person AI photo business was making about $105,000 a month in revenue and roughly $80,000 in profit. That works out to a profit margin of about 76% at more than $1 million in annualized revenue.

The wider SaaS market shows that this is not purely an outlier story. Acquire.com's latest report covered 950 profitable SaaS businesses offered for sale and found an average profit margin of 71%. The figure was 67% two years earlier and 71% in each of the following two years.

A solo founder can therefore reach margins that used to look unusual even for small software companies. The opportunity is especially strong when customers pay repeatedly but the amount of work required to serve another customer barely changes.

What does “best margins” really mean for a one-person business?

For a one-person business, the best margin is the amount of money left after expenses and after we acknowledge that the founder's time is limited.

This immediately creates a problem with consulting.

Imagine a specialist billing $200,000 a year while spending only $10,000 on software, insurance and administration. On paper, the business keeps 95% before tax. If generating that revenue requires 1,600 hours of client work, however, much of the apparent profit is really compensation for the founder's labor.

Now take a software product producing the same $200,000 while spending $40,000 on payments, infrastructure and other costs. Its cash margin is only 80%. Yet if the founder spends 400 hours a year maintaining it, the business produces far more profit for every hour of work.

That is the distinction we use throughout this comparison. A great solo business keeps a large share of revenue while requiring very little extra founder time as sales grow.

Business	Cash-margin potential	Founder time as revenue grows	Quality of margin
Traditional consulting	Very high	Rises quickly	Moderate
Digital downloads	Exceptional	Barely rises	High
Paid newsletter	High	Keeps recurring	High
Online courses	Very high	Low after creation	High
Micro-SaaS	Very high	Rises slowly	Exceptional
AI SaaS	High to very high	Rises slowly	Very high

Which one-person business has the best margins overall?

Narrow B2B micro-SaaS currently has the best overall margins for a one-person business.

The sweet spot is boring software that solves one expensive problem for a specific type of customer. Think automated reports for property managers, compliance reminders for a regulated profession, data synchronization between two tools or software that eliminates a repetitive back-office task.

These products can charge $50, $100 or several hundred dollars a month even when serving each additional account costs only a few dollars. Billing repeats automatically, software updates reach every customer at once and the founder does not need to manufacture or deliver another unit every time somebody pays.

Acquire.com's latest marketplace data is particularly useful here because it measures businesses that are actually profitable rather than venture-backed SaaS companies optimizing for growth. Across 950 profitable SaaS listings, average reported profit margins were 71%. Most profitable businesses in the dataset were above 50%.

Those numbers are hard for most physical businesses to touch. A retailer needs another product when another customer arrives. A restaurant needs more food and labor. An agency eventually needs another person. Well-built B2B software can add its 500th subscriber without multiplying the workload by 500.

The strongest versions also solve problems customers do not enjoy thinking about. A company will keep paying $99 a month for software that quietly handles a painful task if removing it would bring the pain back.

That combination of high margin, subscription revenue and low incremental labor puts narrow B2B SaaS first.

Are Shopify apps even more profitable than normal SaaS?

A good Shopify app can currently have some of the best economics available to a solo developer.

Shopify lets eligible app developers keep 100% of their first $1 million in gross app revenue under its current revenue-share structure. Billing still carries a 2.9% processing fee, and revenue above the threshold is subject to Shopify's 15% share.

Suppose a solo developer sells an app for $100 a month to 500 merchants. That is $50,000 in monthly gross revenue. The 2.9% billing charge represents about $1,450 before the app's own hosting, support and tax costs.

The developer gets something else for that money: access to merchants who are already looking for software, built-in billing and an ecosystem where installing another business tool feels normal.

That can make customer acquisition far easier than launching an independent SaaS product from an empty domain.

There is a real trade-off. Shopify controls the platform, the marketplace and many of the underlying features. A product can lose value if Shopify incorporates the same function directly or changes an API.

Even with that risk, a boring app solving inventory, merchandising, reporting, shipping or another recurring merchant problem can be an exceptional one-person business today.

Do AI businesses have better margins than regular software?

AI software can produce excellent solo-business margins, but ordinary low-compute SaaS still has the cleaner economics.

Photo AI is a striking example of what is possible. At roughly $105,000 in monthly revenue and $80,000 in disclosed monthly profit, its margin comes out near 76%.

That is excellent for a product generating computationally expensive images. It also shows why AI SaaS should be separated from ordinary SaaS.

A conventional application might retrieve records from a database, generate a report or trigger an automation at very little incremental cost. An AI image, video or model inference has a measurable cost every time somebody uses it. Heavy customers therefore eat directly into margin.

Pricing can solve much of the problem. Credit systems, usage caps and higher-priced plans stop a few power users from consuming unlimited compute under a cheap flat subscription.

The most attractive solo AI products today are ones where the customer values the output far more than the inference costs. A business paying $100 to automate a task that saves an employee several hours is much easier to monetize than a consumer paying $10 for unlimited expensive generations.

AI can still create fantastic businesses. For pure margin, software that barely costs anything to run has an obvious head start.

Can digital products make even higher margins than SaaS?

Digital downloads can beat SaaS on pure percentage margin because selling one more template, spreadsheet, design asset or code package costs almost nothing.

A $50 template can be created once and sold 10,000 times without manufacturing 10,000 copies. After the product exists, payment and distribution fees become the main variable expenses.

That makes direct distribution particularly attractive. A payment stack charging only a few percentage points leaves almost the entire sale with the creator. Marketplaces can take substantially more in exchange for providing customers.

The problem is repeat purchasing. Someone who buys a budgeting spreadsheet today usually does not need the same spreadsheet again next month.

A SaaS customer can pay for three years. A template buyer may pay once.

That is why digital products are arguably the pure-margin champion but not our overall winner. They work especially well when a founder already has search traffic, an audience or another cheap source of customers.

The same logic applies to ebooks. Amazon KDP currently offers eligible ebooks a 70% royalty option, with its qualifying U.S. price band recently expanded to $2.99–$12.99. That can be attractive for intellectual property that keeps selling for years, but direct digital products can retain a materially larger share of the customer's payment.

Are online courses still great one-person businesses?

Evergreen online courses remain among the highest-margin solo businesses when the founder owns the audience and the subject does not need constant updating.

The economics can be remarkably simple. Record the material once, host it online and allow hundreds or thousands of students to consume essentially the same product.

Distribution makes an enormous difference.

Udemy currently pays instructors 97% of qualifying net revenue when the customer purchases through the instructor's own coupon or referral link. When Udemy itself generates the sale through its marketplace, the instructor receives 37%.

That is a 60-percentage-point gap for essentially the same course.

We see the same pattern elsewhere in the solo-business economy: creating a cheap product is only half the game. Whoever controls customer acquisition can claim a large part of the economics.

Courses also work better in some categories than others. Mathematics, negotiation, accounting fundamentals or enduring professional skills can remain useful for years. A course about a fast-changing software interface may require continuous rewriting and rerecording.

When the material stays useful and customers arrive organically, a course can come surprisingly close to the economics of a digital download while supporting much higher prices.

Can a paid newsletter really have software-like margins?

Paid newsletters can generate very high margins today, although the founder still has to keep producing something worth opening.

Platform economics vary sharply.

Substack currently takes 10% of each paid transaction, while Stripe's payment and recurring-billing fees sit on top. Beehiiv says it takes 0% of paid-subscription revenue on its paid-subscription stack, leaving ordinary Stripe processing costs.

On $500,000 of subscription revenue, a 10% platform share alone represents $50,000. Once a newsletter reaches meaningful scale, platform choice stops being a tiny operational detail.

The harder issue is time. A useful newsletter has to keep being useful. Research, interviews, analysis and writing do not disappear because subscriber number 5,000 costs almost nothing to email.

Recurring databases, research memberships and intelligence products improve this model because the value can come partly from information rather than constant essays. A founder who maintains a database of permits, procurement opportunities, funding rounds, specialist pricing or regulatory changes can charge repeatedly for access to something customers need refreshed.

That can produce SaaS-like subscription economics without building a large software product.

For newsletters themselves, margins can be excellent. The founder's recurring workload keeps them a step below the best automated businesses.

Are paid databases actually better than SaaS?

A niche paid database can rival micro-SaaS because customers pay repeatedly for information that competitors cannot recreate overnight.

The strongest database businesses gather information that is fragmented, annoying to collect or commercially valuable. Examples include industry pricing, planning applications, tenders, regulatory updates, suppliers, transactions or specialist job openings.

A professional customer might happily pay $100 a month if the data saves several hours of research or surfaces opportunities worth thousands of dollars.

Serving subscriber number 1,000 barely costs more than serving subscriber number 100. The expensive part is gathering and cleaning the information.

That is where these businesses split into two very different categories. If maintaining the database requires the founder to spend all day manually checking records, the apparent software economics disappear. If collection can mostly run through APIs, scraping and automated processing, margins can become exceptional.

Historical data also creates a useful defense. Someone can copy the interface of a simple SaaS tool fairly quickly. Recreating five years of clean proprietary data is much harder.

For the right niche, a solo database business belongs in the same top tier as micro-SaaS.

Is consulting secretly the most profitable one-person business?

Consulting can show spectacular margins, but a consultant usually earns those margins by selling their own hours.

A specialist charging $300 or $500 an hour may have almost no material expenses. Cash margins can easily look better than those of a software company.

The limit appears when demand grows. Ten extra SaaS customers can sign up overnight. Ten extra consulting clients require substantially more time.

Productized services improve the equation.

Take a $5,000 audit that originally requires 30 hours. That produces about $167 of revenue per delivery hour. If templates, software and a repeatable process cut delivery to five hours without changing the price, revenue per delivery hour rises to $1,000.

At that point, the service starts behaving more like a product.

This is why consulting is such a useful starting point for solo founders. Repeated client work reveals exactly what people will pay to fix. The founder can then automate pieces of that work, sell standardized deliverables or eventually build software around the recurring problem.

Traditional consulting is still one of the fastest ways to earn a high income alone. It does not win our margin ranking once founder time is treated as a real cost.

Are mobile apps less profitable than web software?

A mobile app can have excellent margins, but a web business usually lets a solo founder keep more of each direct sale.

Apple's Small Business Program currently charges qualifying developers a 15% commission on paid apps and in-app purchases, provided they remain within the program's revenue limits.

Compare that with a typical direct web card payment, where processing may cost only a few percentage points.

That difference compounds quickly. Giving up roughly 15 cents from every dollar instead of roughly three cents can represent tens of thousands of dollars once a business reaches several hundred thousand dollars in annual sales.

App stores do provide something valuable in return. Customers already have payment details stored, installation is easy and the store itself can generate discovery.

For a consumer founder without an audience, giving up part of the sale can therefore make perfect sense.

A B2B founder usually has less reason to accept that trade. Businesses are already comfortable entering a company credit card on a website, which gives web-based SaaS a margin advantage.

How much does owning your audience change the margin?

Owning distribution can change the margin of a one-person business by tens of percentage points even when the underlying product stays exactly the same.

Udemy gives us the cleanest example. An instructor who brings the customer through a qualifying coupon or referral link receives 97% of net revenue. A normal marketplace-generated sale pays the instructor 37%.

Same course, radically different economics.

Paid newsletters show a smaller but still meaningful version of the same gap. Substack's standard creator fee is currently 10% of paid transactions, while beehiiv advertises a 0% platform cut on paid subscriptions, excluding ordinary payment processing.

Shopify apps sit at the favorable end for smaller developers because Shopify currently takes no revenue share on the first $1 million in qualifying gross app revenue, although its 2.9% processing fee still applies.

Once product-delivery costs approach zero, distribution often becomes the biggest line item left.

This is why an email list, search rankings, a recognizable brand or a community can be worth more than shaving another percentage point off hosting costs. A founder who can reach the next thousand buyers directly has a completely different margin profile from one who must keep renting access to customers.

Business model	Distribution/payment drag before internal costs	Recurring revenue	Founder workload after setup
Direct low-compute SaaS	Low	Strong	Low to moderate
Shopify app below threshold	Very low	Strong	Low to moderate
Direct digital download	Low	Usually weak	Very low
Owned paid newsletter	Low	Strong	Moderate to high
Mobile app-store product	Moderate	Often strong	Low to moderate
Marketplace course	Can be very high	Usually weak	Low

What ruins the margin of a solo business fastest?

Paid customer acquisition is usually the fastest way to destroy the margin of an otherwise attractive one-person business.

Suppose a digital product has a 95% contribution margin before marketing. If finding each customer requires spending 40% of the sale price on ads, much of that beautiful margin disappears immediately.

Support can be almost as damaging because it consumes the founder rather than appearing neatly on a software bill. Ten customers asking occasional questions is trivial. Thousands of low-paying consumers generating refunds, password issues and repetitive support requests can turn a supposedly automated business into a customer-service job.

Variable usage is the third danger. AI inference, third-party APIs, data licensing, video processing and other usage-based costs rise every time customers use the product.

The best solo businesses today avoid all three problems at once. Customers arrive cheaply, rarely need human help and cost very little to serve after they sign up.

That combination matters far more than whether hosting costs $100 or $200 a month.

Can a 90% margin disappear because the business is too easy to copy?

Yes. Some of the easiest businesses to run at 90% margins are also the easiest businesses for somebody else to reproduce.

Templates make the problem obvious. A spreadsheet can have almost no delivery cost, yet another creator can make a similar spreadsheet tomorrow. AI has made producing basic digital assets even faster.

Simple software can face the same pressure. If a product is little more than an interface around somebody else's API, the underlying provider or another founder may reproduce the useful feature quickly.

The stronger solo businesses accumulate something alongside their margin: proprietary data, years of search traffic, customer history, integrations, recognizable expertise or a workflow that becomes annoying to replace.

This is one reason boring B2B apps age surprisingly well. Once software contains a company's settings, runs every day and connects to other systems, switching to save $30 a month may simply not be worth the trouble.

A spectacular margin is valuable. A spectacular margin that survives competition is much rarer.

So which one-person businesses have the best margins now?

Narrow B2B micro-SaaS has the best overall margin profile for a one-person business today, with Shopify apps and automated paid-data products close behind.

Digital downloads can keep an even higher percentage of each sale, particularly when sold directly. Their weakness is that customers usually pay once rather than every month.

Evergreen courses have similarly attractive economics when the creator controls distribution. Paid newsletters can also be very profitable, although publishing valuable material keeps demanding founder time.

AI SaaS deserves a high position rather than first place. Photo AI's roughly 76% disclosed margin proves that a one-person AI company can produce extraordinary profits, but inference still creates a variable cost that ordinary low-compute software largely avoids.

Consulting ranks much lower once we stop treating the founder's working hours as free. The income can be excellent, but each additional client creates additional work unless the service is heavily productized.

The clearest pattern across everything we reviewed is simple: the best solo economics appear when customers pay repeatedly, delivery is automated, serving another customer costs almost nothing and the founder controls customer acquisition.

That is why a small, boring $100-a-month B2B tool can be a better one-person business than something with millions of users.

Rank	One-person business	Margin potential	Recurring revenue	Solo scalability	Verdict
1	Narrow B2B micro-SaaS	Very high	Strong	Exceptional	Best overall
2	Shopify app	Very high	Strong	Exceptional	Outstanding below the revenue-share threshold
3	Automated paid database	Very high	Strong	Excellent	Best information business
4	Direct digital products	Exceptional	Weak	Exceptional	Highest pure margins
5	Evergreen online courses	Exceptional	Weak to moderate	Excellent	Excellent with owned distribution
6	AI SaaS	High to very high	Strong	Excellent	Great if compute stays controlled
7	Paid newsletter / research membership	High	Strong	Moderate	Great margins, recurring founder work
8	Mobile app	High	Often strong	Excellent	Store economics reduce the take
9	Productized consulting	High	Usually weak	Moderate	Strong if delivery is heavily standardized
10	Traditional consulting	Very high on paper	Weak	Poor	Great income, weaker leverage

For someone starting alone today, we would choose a narrow B2B product with recurring payments over almost every other model. The product does not need a giant market. It needs a few hundred customers with an annoying enough problem to keep paying while the software quietly does the work.
