Choosing a deal structure is one of the most consequential decisions when you buy an online business. This guide compares asset purchases, stock or equity purchases, earnouts, holdbacks, seller financing, and transition agreements so you can identify the risks, questions, and safeguards to address before signing.
Overview
A deal structure determines what changes hands, which liabilities remain with the seller, when the seller gets paid, and what happens if the business performs differently after closing. The safest structure is not universal. It depends on the business type, the seller’s legal entity, the quality of the records, the transferability of key assets, the buyer’s available cash, and the level of post-closing support required.
For many small online businesses, an asset sale is easier for a buyer to isolate and review because the agreement can list the specific websites, domains, code, customer records, contracts, inventory, social accounts, and intellectual property being acquired. A stock or equity sale transfers ownership of the company itself, which may preserve contracts and accounts but can also leave the buyer exposed to the company’s existing obligations. These outcomes depend on the jurisdiction, entity type, contracts, and purchase agreement.
Earnouts, holdbacks, and seller financing are payment mechanisms that can be added to either broad structure. They are not substitutes for due diligence. Each should define measurable conditions, deadlines, control rights, dispute procedures, and the consequences of missed performance or delayed cooperation.
| Structure or term | What changes hands | Payment timing | Key questions | Common failure point |
|---|---|---|---|---|
| Asset sale | Specified business assets and selected contracts | Often paid at closing, subject to negotiated conditions | Are all required assets listed and transferable? | An omitted domain, account, license, or liability disrupts operations |
| Stock or equity sale | Ownership of the company and its existing operations | Usually paid to the owners at closing, with possible deferred amounts | What liabilities, contracts, taxes, and claims remain inside the company? | The buyer inherits an obligation that was not identified or protected against |
| Earnout | No separate asset transfer; part of the price depends on future results | Paid after closing if defined targets are met | How are revenue, profit, churn, refunds, and buyer decisions measured? | Ambiguous metrics create disputes over whether the target was achieved |
| Holdback or escrow | Part of the agreed price is retained temporarily | Released after a period or after specified claims are resolved | What claims qualify, and who controls release? | The release process is unclear when a warranty issue appears |
| Seller financing | The business transfers while the seller receives scheduled payments | Over an agreed repayment period | What happens after a missed payment, default, or business downturn? | Security, control, and default remedies are not documented precisely |
| Transition agreement | Seller support, introductions, training, or handover services | Included in the price or paid separately over a defined period | What work is required, for how long, and how will completion be judged? | Informal promises leave the buyer without the knowledge needed to operate |
This table is a planning tool, not a substitute for advice. A lawyer and tax professional should review the proposed structure, especially when the transaction involves employees, regulated data, intellectual property, international parties, or a company with substantial liabilities.
Checklist by scenario
When an asset sale may be appropriate
- Create a complete asset schedule covering domains, websites, source code, databases, content, trademarks, social profiles, analytics properties, customer lists, inventory, equipment, and transferable contracts.
- Separate included assets from excluded assets. A seller’s personal brand, unrelated website, or shared software account should not be assumed to transfer.
- Check whether each platform allows the relevant account, subscription, advertising profile, payment account, or customer data to be transferred.
- Assign responsibility for liabilities tied to pre-closing sales, refunds, taxes, chargebacks, privacy requests, warranties, and intellectual property claims.
- Define how credentials, administrative access, backups, documentation, and recovery methods will be delivered.
When evaluating a stock or equity sale
- Review the company’s formation documents, ownership records, financial statements, tax filings, contracts, bank accounts, debt, and outstanding disputes.
- Identify obligations that remain with the company after the transaction, including employment commitments, subscriptions, vendor agreements, loans, and unresolved customer issues.
- Confirm that ownership can be transferred and that important contracts do not require consent after a change in control.
- Request representations, warranties, indemnities, and survival periods that address the risks discovered during diligence.
- Consider whether the buyer will have enough control to manage the business immediately after closing.
When using an earnout
- Choose metrics that both parties can calculate from records that already exist, such as collected revenue or customer retention under a defined formula.
- Specify the measurement period, target, reporting date, accounting method, permitted business changes, and payment date.
- State how refunds, discounts, taxes, payment processing fees, cancellations, migrations, and unusual one-time sales are treated.
- Address the buyer’s operating discretion. A buyer should not be forced to run the business in an uneconomic way, while the seller may need protection against deliberate actions designed to avoid an earnout.
- Include a records-access and dispute process, with a deadline for raising objections.
When using seller financing or a holdback
- Document the principal, interest if any, payment schedule, maturity date, prepayment rights, late-payment rules, and default remedies.
- Decide whether the seller receives security, a lien, a personal guarantee, or another form of protection, subject to professional advice.
- For a holdback, define the account custodian, release dates, notice requirements, eligible claims, and what happens when a claim is disputed.
- Stress-test the arrangement against lower revenue, a platform suspension, a key customer loss, or a delayed transfer.
What to double-check
Before signing, compare the term sheet, letter of intent, purchase agreement, schedules, escrow instructions, financing documents, and transition plan. They should describe the same transaction. A headline price can be misleading if one document includes working capital, inventory, prepaid expenses, liabilities, or assumed contracts and another does not.
Pay particular attention to:
- Ownership and control: Identify the exact closing moment and the person responsible for each transfer.
- Representations: Confirm that statements about revenue, expenses, traffic, customers, intellectual property, legal compliance, and data are accurate and supported by records.
- Indemnification: Understand which losses are covered, whether limits or deductibles apply, and how claims must be submitted.
- Escrow mechanics: Use a clearly documented release process rather than relying on informal messages between the parties.
- Transition support: List meetings, introductions, training materials, response times, and the point at which support ends.
- Tax treatment: Ask how the purchase price will be allocated among assets or equity and how deferred payments may be treated. The answer can affect both parties.
Use a website acquisition due diligence checklist to connect the proposed structure to the underlying evidence. For valuation context, review how online businesses are valued, but do not let a multiple replace a review of transferability, liabilities, and cash flow quality.
Common mistakes
- Choosing the structure from the price alone. A lower upfront price may carry more operational, tax, or enforcement risk if the deferred terms are vague.
- Using an earnout to solve a trust problem. An earnout works best when the parties can agree on records and controls. It cannot repair missing financial data or unclear ownership.
- Leaving transferability until closing. Verify platform and contract requirements before committing to a structure that depends on accounts moving.
- Relying on a verbal handover. Seller knowledge should become a written transition plan with dates, deliverables, and access requirements.
- Ignoring post-closing disputes. Every deferred payment, holdback, warranty, and earnout needs a process for notices, records, objections, and resolution.
- Assuming an asset sale has no liabilities. The agreement, local law, contracts, and conduct of the parties determine what obligations may follow the assets.

When to revisit
Return to this checklist before submitting a non-binding offer, before signing the purchase agreement, immediately before closing, and again when a deferred payment or earnout becomes due. Revisit it before seasonal planning cycles if the business has material seasonality, because payment capacity and earnout targets may look different across periods.
Update the checklist whenever the business changes its payment processor, advertising platform, hosting provider, customer-data workflow, legal entity, or contract base. Platform transfer rules and escrow practices can change, so confirm current requirements rather than relying on a previous transaction or an old template.
Your final action list should be short and specific:
- Write down the proposed structure and the reason it fits the transaction.
- Mark every open question about assets, liabilities, payment timing, control, and transferability.
- Attach evidence to each material representation.
- Convert verbal promises into schedules, deadlines, or contract clauses.
- Have qualified legal and tax professionals review the documents before you sign or transfer funds.
There is no universally safest way to buy an online business. A well-defined structure is safer because both parties understand what is being transferred, when money moves, how performance is measured, and what happens when the transaction does not go according to plan.
