Buying an established ecommerce business can be faster and less risky than building one from scratch, but only if the legal side is handled properly. This guide walks through each stage of an acquisition from a buyer's perspective and explains where legal risk usually hides.
1. Decide what you are really buying
An ecommerce business is a bundle of assets: a storefront or marketplace account, a brand, product listings, supplier relationships, inventory, customer data, content, domains and advertising accounts. Some of these are legally owned; others exist only because a platform allows them to.
Before making an offer, list which of these assets drive the revenue. If most sales come from one Amazon account, the transferability of that account matters more than almost anything else. If the brand is the value, trademark ownership becomes critical.
2. Agree headline terms in a letter of intent
Once you and the seller agree a price in principle, record the key terms in a letter of intent (LOI). A good LOI covers the price and how it is paid, whether you are buying assets or the company, the diligence period, exclusivity, and any conditions such as transition support.
Most LOI terms are non-binding, but exclusivity and confidentiality usually are. Getting structure and payment terms right at this stage avoids painful renegotiation later. See our guide to the letter of intent for ecommerce acquisitions for more detail.
3. Complete financial and legal due diligence
Due diligence is where you verify what the seller has told you. Financial diligence tests revenue, margins and add-backs. Legal due diligence tests ownership and risk: who owns the entity, the trademarks and the domains; whether contracts can transfer; whether there are tax, product, data or IP problems.
For ecommerce businesses, legal diligence should always include platform account health, IP complaints, supplier terms, sales tax and VAT exposure, and how customer data has been collected. Findings feed directly into price, escrow and the warranties you ask for.
4. Choose the deal structure
Most smaller online businesses are bought as an asset purchase: you acquire the assets and leave the seller's company, and its historic liabilities, behind. Larger businesses, or those whose accounts and contracts cannot easily move, are often bought by acquiring the shares or membership interests of the owning company.
Each structure has different tax, liability and transfer consequences. The choice should be made with both legal and tax advice, ideally before the LOI is signed.
5. Negotiate the purchase agreement
The purchase agreement is the document that protects you. Beyond price and assets, the most important sections are the seller's warranties (statements of fact about the business), indemnities (promises to cover specific losses), limitations on claims, escrow or holdback, non-compete and non-solicitation restrictions, and transition obligations.
Broker and marketplace templates are designed to get deals done quickly and are often light on buyer protection. Reviewing and negotiating these terms is usually where legal advice adds the most value.
6. Close the deal and transfer everything
Closing is when the price is paid and ownership passes. In ecommerce deals, it is really a process: accounts, domains, trademarks, inventory, supplier relationships and software subscriptions move over days or weeks. A written closing checklist, with escrow released against confirmed transfers, keeps control in the buyer's hands.
7. The first 90 days after closing
After closing, track the seller's transition duties, record trademark assignments, update policies and privacy notices under your name, register for any taxes the business now owes, and monitor any earnout or deferred payment. Warranty claim periods usually start at closing, so keep notes of anything that does not match what you were told.
