How to Buy a Micro-SaaS Business: The Complete Acquirer's Playbook
Acquiring an existing micro-SaaS is one of the most effective strategies for software entrepreneurs to skip the zero-to-one phase. By purchasing a business with proven product-market fit, paying subscribers, and working infrastructure, you can focus directly on growth and expansion rather than unvalidated MVP development.
1. Define Your Micro-Acquisition Criteria
Before browsing marketplaces, establish clear acquisition boundaries. Consider your technical skill set, target monthly recurring revenue (MRR), desired deal size, and operational bandwidth.
Most first-time acquirers target businesses priced under $50,000 generating between $500 and $3,000 in MRR. At this scale, products are typically operated by a single founder with low technical overhead, making code handoff manageable.
2. Verify Financial Metrics and Payment History
Never rely solely on screenshots or self-reported metrics. Always request read-only access to the business's payment processor—typically Stripe, Lemon Squeezy, or Paddle.
Examine the last 12 months of net revenue, refund rates, customer churn, and customer lifetime value (LTV). Be wary of sudden revenue spikes right before a listing, which may represent temporary annual billing pushes.
3. Perform Technical & Codebase Due Diligence
Review the application's source code architecture. Is the repository clean and documented? What third-party APIs does it rely on (OpenAI, AWS, Supabase, SendGrid)?
Calculate monthly infrastructure costs against gross revenue. If an AI SaaS generates $2,000/mo but incurs $1,200/mo in LLM tokens and vector hosting, net margins may be too thin.
4. Structure the Offer and Escrow Transfer
Use a standardized Asset Purchase Agreement (APA) outlining all transferred intellectual property, domains, customer data, and code repos.
Fund the purchase via a neutral escrow platform such as Escrow.com. Inspect domain ownership, server admin rights, and database access before authorizing final fund release.
