Building a micro-SaaS

Differences worth understanding:

• ICP — micro-SaaS targets a narrow vertical (e.g. yoga studios, dental practices) where a full SaaS company won't be efficient.
• Price — $9-99/mo typically; full SaaS often $200+.
• Acquisition — self-serve via content/SEO; no sales calls.
• Support — low-touch; chatbot or async email is enough.
• Team — one person can run it indefinitely.

The trade-off: lower ceiling on revenue, much lower operational complexity, much higher solo-founder fit.

The best micro-SaaS niches share three traits:

1. Big-name SaaS is too expensive or too complex for the segment.
2. The buyer is reachable — they're in one community / read one publication / attend one conference.
3. Recurring need — software gets used every week, not every year.

Bad niches: "marketing for small businesses" (too broad, big-name competition). Good niches: "appointment booking for solo personal trainers" (narrow, specific, reachable).

Micro-SaaS pricing:

• Single low tier is fine when starting. $19/mo or $29/mo.
• Annual prepay with 20% discount improves cash and retention.
• Don't try to upsell if the product only does one thing. Just charge a fair price for it.

The temptation to add tiers and upsells before product-market-fit is the most common micro-SaaS mistake.

Self-serve channels that work for micro-SaaS:

• SEO for specific tool searches ("best X tool for Y").
• Niche communities where your ICP gathers.
• Marketplace listings if your category has them (Shopify app store, Notion templates, etc.).
• Comparison content ("Tool X vs Tool Y") for buyers researching alternatives.

Notably absent: cold outreach (price too low to justify), paid ads ([CAC payback](/glossary/payback-period) too long), influencer marketing (audience too broad).

Micro-SaaS economics only work if the founder isn't spending all day on support. The targets that keep solo micro-SaaS sustainable:

• Support tickets per 100 customers per month: under 10. Above that, the product has a UX problem (or you've sold to the wrong ICP); above 25, you can't grow without hiring.
• Median first-response time: under 24 hours. Doesn't have to be instant — micro-SaaS customers don't expect Slack-grade responsiveness — but anything past 48h kills retention.
• Self-serve docs cover 80%+ of common questions. A simple help-centre with 20-30 articles deflects more support than chat ever will.

The operational tools that earn their keep at solo scale: Plain or Help Scout for tickets (Crisp's free tier is OK to start), a status page (Atlassian Statuspage free tier or BetterStack), error tracking (Sentry free tier covers most micro-SaaS volumes), and Stripe Smart Retries for payment failures. Total tooling spend at this stage: under $80/mo. Resist adding more.
