Micro SaaS is a narrowly scoped software-as-a-service product, usually run by one person or a small team. It does not need to become a platform for everyone; it only needs to solve one recurring problem well enough for a group of customers willing to pay.
The hardest part is rarely writing the first feature. Harder still is finding the right problem, reaching users and keeping the service stable for months after they pay.
What makes a good micro SaaS idea?
- The problem happens often and currently costs time or money.
- The customer group can be identified and reached.
- The solution can start with one core function.
- Value is created continuously, which suits a subscription model.
- Legal, data and platform-dependency risks stay within your control.
Find the problem before thinking about features
Look at the manual work in an industry you understand: spreadsheets that must be updated daily, reports assembled from several sources, notifications that are easy to miss, or data that gets re-entered repeatedly. Interviews should focus on how the customer works today and what the inconvenience costs, not on whether they like your idea.
An MVP only needs to complete one job
- 01
Describe the outcome
Write one sentence about what the user can complete faster after using the product.
- 02
Build the main flow
Focus on input, processing and output; postpone customisation that few people need.
- 03
Onboard manually
Set it up alongside your first few customers to understand the friction, rather than automating too early.
- 04
Charge early
One small payment validates the value better than a list of people who say they are interested.
Practical pricing and operations
- Price on value and usage, not just server cost.
- Set clear plan limits so one customer cannot consume all the resources.
- Monitor errors, backups, security and uptime.
- Write documentation, a status page and an easy-to-find support channel.
- Include support time in the profit calculation for each plan.
Three signals that matter more than sign-ups
- Activation: how quickly a user completes the core job.
- Retention: whether they come back after a few weeks.
- Churn: why customers cancel, stop using it or do not renew.
