How to buy a micro-SaaS

A workflow-first foundation for sourcing, screening, diligencing, and taking over a small software business without confusing activity for conviction.

Primary question

What is the cleanest way to approach a micro-SaaS acquisition from search to transition?

Practical takeaway

Treat acquisition as a written operating process with thresholds, not as a deal hunt driven by vibes.

Key points

  • Define size, market, and complexity constraints upfront.
  • Use screening criteria before live diligence begins.
  • Model the transition workload, not only the purchase price.
  • Write the offer decision as a memo before you negotiate the final narrative.

Decision frame

Start with a search thesis, not with a marketplace tab

The fastest way to waste time in acquisitions is to browse too broadly. A better starting point is a thesis about revenue size, founder dependency, product complexity, and your own appetite for transition work.

That thesis becomes a filter. It prevents you from burning cycles on listings that look interesting but would create the wrong kind of workload after the deal closes.

  • Define what revenue band is worth your attention.
  • Decide whether you want technical, content, or workflow-heavy businesses.
  • Reject opportunities that fail the thesis before you start building narrative around them.

Build the search thesis first

A good acquisition search starts with constraints that protect your time and attention.

  • Set a revenue band that is big enough to matter and small enough to understand.
  • Define how much founder dependency you are willing to inherit.
  • Decide whether you want product complexity or operational simplicity.
  • Write down why this kind of business fits your current capability set.

Note

Browsing is not a strategy

The faster you move from curiosity to a written thesis, the less likely you are to waste weeks on opportunities that were never a fit.

Screening

Write your rejection rules before you start diligence

Most acquisition processes fail because the buyer keeps learning without deciding. Screening rules solve that.[1] They force a fast yes, no, or maybe decision before the diligence workload expands.

That means setting thresholds for churn, concentration, support burden, founder dependency, and evidence quality around the reported metrics.[2]

  • Revenue without retention evidence is not a real signal.
  • A business that only works because the founder manually rescues edge cases deserves a penalty.
  • The goal of screening is to preserve focus for the few deals that deserve full diligence.

Transition

Judge the business and the handoff separately

A decent business can still be a bad acquisition if the transfer burden is too high. Buyers consistently underprice knowledge transfer, customer communication, access changes, and documentation cleanup.

The handoff plan should be treated as a second risk profile with its own checklist, timeline, and support assumptions.

  • Model the first 30 days after close as an operating sprint.
  • Score how legible the product, support, and analytics setup already are.
  • Never collapse transfer risk into a single line item called onboarding.

First 30-day transfer lens

Week 1

Control the systems

Ownership changes for domains, hosting, billing, analytics, and support need a clear order so nothing mission-critical is left half-owned.

System control

Week 2

Stabilize customer communication

Customers should know how support works now, what changes, and where continuity still exists. Silence creates avoidable churn risk.

Customer trust

Weeks 3-4

Turn hidden knowledge into operating notes

The seller's tacit workflows should become documented routines before the support window ends.

Knowledge capture

Decision memo

Write the deal case before you write the offer

A buyer should be able to explain the acquisition in one page before price conversations get emotionally sticky. The memo should say what makes the business attractive, what could break after transfer, which assumptions still need evidence, and what price or terms those risks justify.

This matters because negotiation can make weak deals feel more real than they are. The memo keeps you anchored to operating logic instead of seller momentum.

  • Write the upside and the fragility in the same document.
  • Name the open questions that would still kill the deal.
  • Separate a good business from a good deal at this price.
