building a saas from zero takes years. buying one takes months.
more founders are skipping the cold start and acquiring existing saas businesses instead. recurring revenue from day one. customers already paying. product-market fit proven.
this is the complete guide to buying your first micro-saas.
why buy instead of build?
| building | buying |
|---|---|
| 12-24 months to revenue | revenue from day one |
| $0 revenue while building | €1K-50K MRR immediately |
| product-market fit uncertain | already validated |
| customer acquisition from scratch | existing customer base |
| high failure rate | proven business model |
the math is simple: if you can buy €5K MRR for €150K and grow it to €10K MRR, you have doubled your money faster than building from zero.
what to look for
not every saas is worth buying. here is what separates good acquisitions from bad ones.
the ideal micro-saas acquisition
| factor | ideal | acceptable | avoid |
|---|---|---|---|
| mrr | €2K-20K | €500-50K | < €500 |
| monthly churn | < 2% | 2-4% | > 5% |
| owner hours/week | < 5 | 5-15 | > 20 |
| age | 2+ years | 1-2 years | < 6 months |
| growth | stable or growing | flat | declining |
| customer concentration | < 20% top customer | < 30% | > 40% |

direct outreach
you can also find deals by:
- reaching out to saas founders directly
- posting in indie hacker communities
- networking at saas conferences
- contacting founders of products you use
direct deals take more effort but can result in better prices.
how to evaluate a deal
step 1: initial screening
before going deep, filter quickly:
- does the revenue match the asking price (2-4x annual profit)?
- is the churn sustainable?
- can you realistically operate this?
- does the market have room to grow?
if any answer is no, move on. there are plenty of deals.
step 2: financial analysis
calculate the real numbers:
| metric | formula |
|---|---|
| annual revenue | mrr × 12 |
| annual profit | revenue - all expenses |
| profit margin | profit / revenue |
| payback period | purchase price / annual profit |
| break-even mrr | your expenses / 12 |
a healthy micro-saas should pay for itself in 2-4 years.
step 3: due diligence
this is where you verify everything. see our full saas due diligence checklist.
key areas:
- revenue verification (stripe access)
- customer health (churn, retention)
- technical assessment (code quality)
- legal review (asset ownership)
- operational assessment (owner dependency)
how to value a micro-saas
the baseline is simple:
annual profit × multiple = valuation
typical multiples for micro-saas:
| business quality | multiple range |
|---|---|
| declining or high churn | 1.5-2x |
| stable, moderate churn | 2.5-3x |
| growing, low churn | 3-4x |
| fast growing, very low churn | 4-5x |
factors that increase multiples
- low churn (< 2% monthly)
- consistent growth (> 10% mom)
- low owner dependency (< 5 hours/week)
- verified revenue
- diversified customer base
- strong market position
factors that decrease multiples
- high churn (> 5% monthly)
- declining revenue
- high owner dependency
- unverified metrics
- customer concentration
- technical debt
how to negotiate
starting the conversation
never open with your maximum price. ask:
- "what is your ideal outcome?"
- "what would make this deal work for you?"
- "is the asking price firm?"
most sellers expect negotiation. the asking price is rarely the final price.
negotiation levers
price is not the only thing you can negotiate:
| lever | what it means |
|---|---|
| payment terms | lump sum vs installments |
| earnout | payment tied to performance |
| transition period | how long seller stays |
| non-compete | what seller cannot build |
| escrow holdback | protection against issues |
| asset inclusion | what is included in sale |
deal structures
typical micro-saas deal structures:
all cash: simplest. buyer pays full amount at close.
earnout: 70-80% upfront, 20-30% after 6-12 months based on revenue retention.
seller financing: buyer pays over time. common for larger deals.
closing the deal
the closing process
- letter of intent (loi): non-binding agreement on key terms
- due diligence: verify everything (2-4 weeks)
- asset purchase agreement (apa): legal contract
- escrow: funds deposited with third party
- asset transfer: code, domains, accounts moved
- verification: buyer confirms transfer
- escrow release: seller receives payment
what gets transferred
| asset | transfer method |
|---|---|
| domain | registrar transfer |
| codebase | github/gitlab transfer |
| hosting | account transfer or migration |
| customer data | database export/import |
| third-party services | account credentials |
| documentation | shared drive access |
the transition period
most deals include 30-90 days of seller support:
- answering questions
- introducing key customers
- explaining undocumented processes
- handling edge cases
negotiate this upfront. a bad transition can sink the deal.
post-acquisition playbook
you bought the saas. now what?
first 30 days
- learn the product deeply
- respond to all support tickets
- meet the biggest customers
- document everything you learn
- do not make changes yet
days 30-90
- identify quick wins
- fix obvious problems
- improve onboarding
- reduce churn
- stabilize operations
after 90 days
- implement growth initiatives
- optimize pricing
- expand marketing
- consider additional features
- look for operational efficiencies
common mistakes to avoid
- buying potential instead of results: pay for what exists, not what could be
- skipping due diligence: verify everything, especially revenue
- underestimating transition: budget time and energy for learning
- changing too much too fast: understand before you optimize
- ignoring technical debt: it will catch up with you
- overpaying for growth: stable revenue is often better than hockey sticks
