Buying a SaaS Business
Forget the ARR Headlines
Venture-scale SaaS trades on ARR multiples; the SaaS a searcher buys does not. BizBuySell's sold software and app listings put half the market between 2.38x and 4x SDE across 2021 to 2025, with a 3.12x median. The publisher reads 4x as the top of that middle range rather than the floor of a premium tier: a business over $1M of sales may approach it, while one under $200k trades just above 2x. ARR multiples only enter the conversation for growing, team-run companies. When a listing quotes an ARR multiple on a founder-run product, translate it back to SDE before comparing anything.
Churn Is the Thesis
Recurring revenue is only as good as its retention, and analysis of SaaS pricing consistently shows churn differences translating into multiple-turn valuation gaps. Pull cohort retention, not the blended rate: logo churn and revenue churn separately, expansion revenue, and how the oldest cohorts behave. A product whose customers leave at 8% a year is a fundamentally different asset from one at 3%, whatever the identical MRR charts suggest.
The Founder Is Usually the Engineering Team
Most searcher-sized SaaS was built and is maintained by the selling founder personally, which puts the company's entire technical capacity on the departing party. Underwrite the handoff explicitly: documentation quality, code maintainability (an independent technical review is worth its fee), deployment and incident processes, and what happens on the first serious bug after the transition period ends. Your plan needs a named answer to 'who fixes production at 2 a.m.,' and that answer costs money that belongs in the model.
Revenue Quality Beyond the Churn Rate
Map the acquisition channel too, since a product fed by the founder's audience or content often churns its growth engine at close. Two assignments decide whether an asset deal works at all: a change of registrant on the domain starts a 60-day transfer lock unless the seller opts out first, and the payment account moves only with notice and a written assumption. A stock sale avoids both. Look inside the MRR:
- Annual prepays create deferred-revenue obligations that transfer to you
- Discounted legacy plans cap your pricing power
- A few whale accounts can concentrate a 'diversified' subscription base
- Marketplace-dependent distribution (an app store, a platform's plugin directory) imports platform risk exactly as FBA does
What to Verify in Diligence
Beyond cohorts and code: infrastructure and hosting costs at current pricing, third-party API dependencies and their terms (a critical API repricing can erase the margin), license compliance in the codebase, data-protection posture, and breach history, support ticket volume and who answers it, intellectual-property assignment from every contractor who ever touched the code, and the payment stack's transferability. For anything AI-adjacent, unit economics per customer at real usage, since inference costs scale with success.
Financeability Notes
Small SaaS deals often close with more structure and less bank debt than main-street businesses: earnings histories are short, collateral is nonexistent, and many lenders pass, though SBA loans do close on established, documented products. Seller notes, earnouts tied to retention, and marketplace escrow are common. Model debt service, where debt exists, on retention-adjusted revenue with a real budget line for the development capacity you must replace.
Terms in This Industry
Expansion revenue
Extra money from existing customers, through more seats, more usage or a higher tier.
Logo churn versus revenue churn
Two measures of the same leak: one counts the customers lost, the other counts the dollars.
Gross revenue retention
What last year's customers still pay this year before any upgrades, capped at one hundred percent.
Seat-based versus usage pricing
Whether customers pay per person or per unit of what they consume, which sets how revenue moves.
Successor assignment
The clause that lets a customer contract follow the business, and the conditions that void it.
What the Data Says
BizBuySell's sold software and app listings put half the market between 2.38x and 4x SDE across 2021 to 2025, with a 3.12x median, on a $625,000 median sale price and $483,261 of median revenue. The publisher reads 4x as the top of that middle range rather than the floor of a premium tier: a business over $1M of sales may approach 4x while one under $200k trades just above 2x.

SaaS Capital's 14th annual survey of more than 1,000 private B2B SaaS companies puts 2025 median growth at 22%, down from 25% in 2024, with only 7.3% of companies flat or shrinking and bootstrapped companies at 20% median against 25% for equity-backed; the growth backdrop any SaaS deal's projections get underwritten against.

The publisher names low owner involvement among the drivers that put a software business at or above the upper quartile, alongside consistent financials, growth potential, a defensible niche and subscription revenue, with full-time owner involvement and many direct competitors pushing it to the bottom. Nobody at this bar quantifies what documentation is worth, so treat the effect as directional.

What It Costs to Replace the Owner
The multiples above are quoted on SDE, which adds the owner's pay back into earnings, so they hold only if you do the owner's job. Hire someone instead and the going rate for the role comes back out. For this trade that is usually the technology manager who owns delivery, paid a median of $175,140 a year nationally. Subtract it from SDE before applying any multiple, because at a 3x multiple that wage also takes about $525,420 off what the business is worth to you.
