How to buy an online business

Every week someone buys a "profitable" content site for a 3x multiple, discovers that 80% of the traffic came from one algorithm update that has already rolled out, and spends two years earning back half the purchase price. The failure is rarely bad luck. It's skipping four hours of verification.

This guide is that four hours, written for a first-time buyer who is willing to read a P&L.

1. Why buying beats building (sometimes)

You buy a business when time is your scarcest resource. An established business gives you three things a new one doesn't: cash flow on day one, a customer list that already trusts someone, and proof that the demand exists. You cannot fake any of those.

You should not buy when you need the business to be exactly what you'd have built. You are inheriting decisions — tech stack, brand, suppliers, pricing, staff — and changing them costs money. If you want control more than cash flow, build.

2. Where online businesses actually change hands

• Curated marketplaces. Places where sellers are vetted and numbers are semi-verified — including the deal flow at builders.to. Best for buyers who want volume with some filter.
• Brokers. They run a process for the seller and charge 8–15%. You get less choice and better-prepared sellers. Good for deals over $500k.
• Direct outreach. The highest-quality deals are never listed. Find a business you'd love to own, email the founder something useful, and ask if they've considered a transition. Slow, but the multiples are lower because there's no auction.
• Communities and founder networks. Newsletters, Slack groups, and indie communities where people mention they're "thinking about moving on". Watch for these; they're warm and unsophisticated, in a good way.
• Marketplace auctions. Cheapest listings and the most adverse selection. Fine if you do full diligence; terrible if you bid on a teaser.

3. The 30-minute screen: kill bad listings fast

Most listings deserve two minutes, not two weeks. Ask these six questions before you read the memorandum:

1. What exactly makes the money? One product, one channel, or diversified? A business earning $10k/month from one Google keyword is a bet on that keyword.
2. How much does the owner work? Ten hours a week is an asset. Fifty hours a week means you're buying a job — and the price already includes unpaid labour.
3. Is the revenue recurring or transactional? Subscriptions and retainers are worth materially more per dollar than one-off sales.
4. How old are the customers? Cohort data beats total revenue. If all growth came from a spike eight months ago, you're buying a memory.
5. What is the traffic or acquisition source, specifically? Paid ads that stop the day you take over are not traffic. Ask for channel-level numbers by month.
6. Why is it for sale? Boredom, a baby, a new job — fine. "Moving on to new projects" plus declining traffic — a warning.

If a seller won't share profit-and-loss statements and traffic by channel before you sign an NDA-backed LOI, they're not selling. They're advertising.

4. How to value an online business

Prices are quoted as a multiple of profit — usually seller's discretionary earnings (SDE) or annual net profit. The multiple is set by durability, not by size.

Business type	Typical multiple	What moves it up
Content / affiliate site	2.5x–4x profit	Diversified traffic, email list, evergreen content
Ecommerce / DTC	2x–4x profit	Repeat customers, brand search, supplier moat
Micro-SaaS	3x–5x profit	Low churn, organic acquisition, small team
Newsletter / media	3x–6x profit	Sponsor diversity, open rates, audience ownership
Productized service	2x–3.5x profit	Documented delivery, non-owner team, retainers

Rules that keep you out of trouble:

• Value profit, not revenue. A $500k-revenue store with 8% margin is a $40k profit business.
• Normalise the profit. Add back the owner's personal expenses, one-off costs, and any salary you'll have to replace. Then subtract the market cost of the work the owner was doing free.
• Discount single-channel risk. Cut 20–40% off the multiple if more than half of traffic or revenue comes from one source.
• Pay for what transfers. Audience, brand, customers, and code transfer. The founder's personal Twitter following usually doesn't.

5. Due diligence: the checklist that matters

Financial

• 24 months of P&L and bank statements — reconcile them. Revenue that doesn't hit a bank account isn't revenue.
• Processor statements (Stripe, PayPal, Shopify) with chargebacks and refunds.
• Customer concentration: what percentage of revenue comes from your top customer?
• Any debt, loans, or liabilities that attach to the business rather than the person.

Traffic and marketing

• Analytics access (read-only) for 12 months, not screenshots.
• Search Console: which queries, which pages, and any manual actions.
• Ad account history: spend, CAC, and what happens when you pause.
• Email list size, last send date, and open rates.

Technical

• Who owns the domain, the code, and the hosting accounts — and will they transfer all three?
• Any custom workarounds only the seller understands. Get them documented before close.
• Licences, plugin costs, and API dependencies that could break or increase.
• Security basics: backups, admin list, and whether customer data is being handled legally.

Legal and operational

• Contracts with suppliers, freelancers, and customers — which ones need consent to assign?
• Trademarks and any claims of infringement.
• Tax registrations in the jurisdictions where you sell; uncollected sales tax or VAT can become your problem.

6. Deal structure: cash, earn-outs, and escrow

A simple asset purchase is normal for small deals: you buy the domain, code, content, customer list, and accounts, and you don't inherit the seller's company. For anything larger or with employees, use a lawyer and probably a share purchase.

• Escrow. Never wire full payment directly. Use an escrow service and release funds when accounts transfer.
• Holdback. Keep 10–20% for 30–90 days against undisclosed liabilities. Standard, and honest sellers accept it.
• Earn-out. If the seller claims the business will grow, pay part of the price against future revenue. It aligns incentives and caps your downside.
• Seller financing. 20–50% financed by the seller over 12–24 months is common and usually means they believe the numbers.
• Transition support. 30–60 days of agreed hours, with an intro to key suppliers and customers, written into the agreement.

7. The transfer and the first 90 days

Closing is an administrative event; the transfer is the actual work. Do these in order, and change nothing else for a month.

1. Domains, DNS, hosting, repos, and analytics moved to accounts you control.
2. Payment processors re-verified under your entity; payouts pointed at your bank.
3. Email list exported and moved to your sending platform — check deliverability before you send.
4. Passwords rotated, old admin access removed, two-factor on everything.
5. Customers told something true and short, from the brand, not from you personally.
6. Suppliers and freelancers introduced, contracts re-signed in your name.
7. Only after week four: start testing improvements. Changing the offer and the ad account and the pricing in week one means you'll never know what broke.

8. Red flags and common mistakes

• Revenue you can't verify. Screenshots are not statements.
• Traffic in a single keyword. One update can halve the business.
• The seller's personal brand is the distribution. If they leave and the audience follows them, you bought a ghost.
• No documented processes. You're buying a black box you must reverse-engineer while it runs.
• Paying a full multiple with no holdback or earn-out. You've removed every incentive for the seller to help.
• Buying something you don't want to run. The most common regret isn't price; it's the Tuesday-afternoon work.
• Skipping tax advice. Cross-border asset purchases have real consequences. One hour with an accountant is cheap.

FAQ

How much money do I need to buy an online business?

Small content sites and micro-SaaS change hands from $10k. Meaningful cash flow usually starts around $100k–$300k, and seller financing or an SBA-style loan can cover part of it.

How long does the process take?

Six to twelve weeks from first contact to close for a small asset purchase, assuming clean numbers. Diligence, not negotiation, is what takes the time.

Can I buy a business with no experience in the niche?

Yes, if you're willing to learn the customer and the channel fast, and if the business doesn't depend on a relationship you can't inherit. Buy a boring business you can operate, not a dream you'll have to rebuild.

Do I need a lawyer and an accountant?

For anything above roughly $25k, yes. A template asset purchase agreement plus a fifty-minute tax conversation prevents the expensive mistakes.

What multiple should I expect to pay?

Two to five times annual profit is the normal band for small online businesses. Above that you should be buying something with real recurring revenue, low churn, and a team that stays.
