How to Buy a SaaS Business
The seven steps to go from "I want to own a cash-flowing SaaS" to closing a deal that actually pencils out. Written for buyers who care about ROI and payback more than headline MRR.
Set a thesis before you look at listings
Decide what you're buying before you start browsing. Ticket size ($5k–$25k, $25k–$100k, $100k+), category (dev tools, prosumer, B2B SMB, mobile subscription), and hold period (flip in 12 months vs. own for 5 years) all change which listings are actually a fit. Buyers without a thesis end up chasing whatever's shiny and overpay every time.
Source deals from more than one place
The best listings never hit the largest marketplaces. Layer three sources: (1) curated indexes with verified metrics — Startup Index for TrustMRR-verified SaaS and apps; (2) large public marketplaces for volume; (3) direct outreach to founders in your thesis who don't have "for sale" in their bio. Rule of thumb: review 20 listings for every 1 you diligence, diligence 5 for every 1 you offer on.
Filter on ROI and payback first, not asking price
The two numbers that matter: annual ROI % (annual profit ÷ asking price) and payback in months (asking price ÷ monthly profit). Anything under 40% ROI/yr or over 30-month payback is broker-tier — fine for strategic acquirers, wrong for indie buyers who want cash back fast. Use our ROI calculator and payback calculator to sanity-check any listing before opening the diligence folder.
Underwrite the multiple against churn and growth
Small SaaS trades 2.5×–4× ARR. Growth and low churn push toward the top; concentration and rising churn pull toward the bottom. Every 1% monthly churn above 3% typically knocks 0.3× off the fair multiple. Read our valuation guide and use the SDE calculator to test the number the seller is asking against the number you'd defend to yourself.
Do the diligence that actually catches bad deals
Verify MRR against payment processor payouts (Stripe, Paddle, RevenueCat). Ask for cohort retention over the last 12 months — aggregate churn hides fresh cohorts churning 2–3× faster. Read the code repo and confirm the seller can hand it over cleanly. Check customer concentration (nobody over 20% of MRR is healthy). Our SaaS due diligence checklist is the full field guide.
Structure the offer with terms, not just price
Cash-at-close is what sellers want. Terms — earn-outs tied to retained MRR at 6 and 12 months, seller financing, escrow holdbacks for account takeover risk — are what protect you. A $50k deal with $10k held in escrow for 90 days against seller-side breakage is a very different deal than $50k wired at close. Use terms to bridge valuation gaps instead of walking away.
Plan the transition before you sign
The seller has a rolodex, the answers to a hundred small operational questions, and login credentials to a dozen third-party services. Negotiate 30–60 days of transition support in writing, with a working handoff document — customer list with notes, vendor list with account IDs, incident history, monthly opex breakdown. Deals fall apart in the 60 days after wire, not before.

Frequently Asked Questions
How much money do I need to buy a SaaS?
Indie SaaS deals start around $5k for hobbyist projects and stretch to $500k for cash-flowing indie businesses. The sweet spot for first-time buyers is $25k–$100k — small enough to write a check, large enough that the seller took it seriously.
How long does it take to buy a SaaS?
From first outreach to close: 4–12 weeks for indie deals under $100k, 8–20 weeks for larger deals. Diligence is the slow part — cohort retention, financial verification, and code review can each take 1–2 weeks.
Should I use a broker or buy directly?
For sub-$100k SaaS, direct is usually faster and cheaper. Brokerage overhead doesn't fit the ticket size. For $500k+ deals, a broker's diligence prep and closing infrastructure save time. Startup Index covers the direct band; brokerages cover the larger band.
What multiple should I pay for a SaaS?
Indie SaaS: 2.5×–4× annual revenue, with growth and low churn pushing to the top and concentration risk pulling to the bottom. Every 1% monthly churn above 3% typically knocks about 0.3× off the fair multiple.
What are the biggest risks?
Revenue concentration (top customer >20% of MRR), churn trending up over the last 6 months, code the seller can't hand over cleanly, and dependency on the seller's personal audience or SEO position that won't transfer. Each is a real deal-killer, not a haggle point.
Do I need a lawyer?
For deals over $25k, yes. An APA (Asset Purchase Agreement) with proper reps and warranties costs $1,500–$5,000 and prevents most post-close disputes. Under $25k, a well-drafted template plus escrow is often enough.
