Micro SaaS: Small Subscription Software Run by Very Few People

Micro SaaS is informal shorthand rather than a formal category. It describes software-as-a-service that is deliberately small: one clear job, a modest customer base, and a team of one to a few. This page speaks to two readers: the founder building one, and the business considering buying from one.

What makes a product micro

• One job. It does a single thing well rather than being a suite.
• A specific audience. Customers share a trade or a recurring problem.
• Small team. Often one person, sometimes two or three.
• Modest scope. It avoids features that would require a large organization to maintain.
• Subscription pricing. Customers pay regularly for continuing use.

For the founder: scope is the discipline

A small product stays alive by saying no. Every added feature adds support questions, bugs to fix and settings to explain. Decide what the product will not do, write it down, and refer requests to that list. Also decide in advance how many customers you can serve with the time you have. Growth beyond that point needs either help or a higher price.

For the founder: support is the real workload

Building the first version is often the shorter part. Answering questions, fixing issues and handling account problems continues as long as there are customers. Plan hours for it each week. Clear documentation, helpful error messages and an honest "what is and is not supported" page reduce the load more than any tool.

For the founder: pricing and honesty

Charge enough to pay for your time and the costs of running the service. Say plainly what the product does, what it does not do, and what happens if you stop running it. Customers deal better with a limit stated early than with a surprise later.

For the buyer: what to check

1. Continuity. What happens if the founder is unavailable for a month, or stops the product altogether?
2. Data. Can you export everything in a normal file?
3. Dependencies. Does it rely on another platform's connection that could change?
4. Support. Is there a published way to get help, and a realistic response time?
5. Terms. Are privacy and data handling written clearly?

Strengths of small software

Small products can be remarkably clear and focused. A founder who answers your email personally is a real advantage. Prices can be modest, and features often match a particular workflow closely.

Risks to keep in view

The main risks are concentration and continuity. One person leaving, one platform changing its rules, or one customer dominating the revenue can end a small product. Treat micro SaaS tools as replaceable parts of your process and keep your data portable.

When micro SaaS is not the right choice

If the tool holds data your business cannot afford to lose, or your process needs round-the-clock support, a small product may be a poor match. Likewise, if you are building one and the market needs much more than one job, a broader approach may be necessary.

Example: an inspection-report tool

A founder who used to work in a property office notices that colleagues spend hours each week producing the same inspection reports from photos. She builds a small web tool that arranges photos and notes into a report. She charges a modest monthly fee, keeps the product to that single job, and answers questions herself. After a while she has a small group of paying customers who found her through trade forums and word of mouth.

She does not try to add accounting, scheduling or tenant messaging, though customers sometimes ask. Each of those would mean a different set of rules, much more support and a larger team. The discipline of staying small is the source of both her satisfaction and her limits.

Questions a founder should answer before starting

• Can I describe the job and the customer in two sentences?
• Do people already pay for a clumsy solution, such as hours of manual work?
• Who will answer questions on a busy week?
• What happens to customers if I stop?
• Is the market large enough to support the effort, and small enough that larger companies ignore it?

Honest answers cannot promise success, but they will prevent the most common surprises.

Choosing where to host and what to rent

A very small product depends on rented services: hosting, payments, email delivery and sign-in. Pick well-established providers, understand their pricing as you grow, and keep your data exportable. Write down which service is used for which job so you can replace one if it changes terms. Avoid using obscure services for core functions, since you would be the only customer asking for help. Backups matter more, not less, when a single person runs everything.

Questions a buyer should ask a one-person vendor

• If you are unavailable for several weeks, how will customers get help?
• Do you have a plan for what happens if you stop running the product?
• Where is my data stored and who can access it?
• How often is the product updated, and how do you announce changes?
• Can I export everything, and have you tested that?

A candid, specific answer is worth more than an impressive feature list. Small vendors who have thought about continuity are the ones worth trusting with your records.
