Due Diligence Checklist for Buying E-commerce or Amazon FBA Business
E-commerce diligence requires channel-level reconciliation, account transfer analysis, inventory quality, advertising economics, intellectual property, supplier continuity, platform compliance, data ownership, and concentration risk. Use this buyer checklist to verify earnings, operations, records, transferability, and hidden capital needs.
A practical research brief from the Business Buyer Check learning library.
Industry Economics to Reconcile
E-commerce diligence requires channel-level reconciliation, account transfer analysis, inventory quality, advertising economics, intellectual property, supplier continuity, platform compliance, data ownership, and concentration risk.
Build monthly and trailing views. Preserve the source, period, entity, and reconciliation for each material conclusion.
- Reconcile platform settlements, orders, refunds, chargebacks, payment reserves, bank deposits, sales tax, and tax returns
- Analyze contribution margin after fees, fulfillment, storage, returns, discounts, freight, advertising, and customer acquisition
- Normalize owner content, sourcing, advertising, customer service, software, contractors, and inventory write-downs
Operations and Assets
Observe the operating process and compare it with the financial story. Identify the people, equipment, systems, locations, and outside relationships that can stop revenue after closing.
- SKU-level sales, margin, cohorts, seasonality, returns, stockouts, aging, storage, and obsolete inventory
- Supplier contracts, MOQs, lead time, quality, tooling, exclusivity, freight, customs, and concentration
- Platform health, policy warnings, suspensions, reviews, brand registry, domains, code, creative, trademarks, and data
Official Records and Compliance Routes
Start with exact legal names, addresses, license or facility identifiers, and transaction structure. Search the responsible official authorities and record coverage limits; a no-result search is not a guarantee.
- Secretary of State, UCC, courts, trademark and relevant customs or product-regulator sources
- Sales-tax registrations and marketplace-facilitator treatment by state
- Consumer safety, FTC, FDA, FCC, CPSC, or other product-specific regulators where applicable
What Must Transfer
Obtain written confirmation where consent, assignment, change of control, new application, or account migration may apply. Build approval lead time into the closing plan.
- Marketplace and payment accounts under current platform rules
- Brand, trademark, domain, content, code, email list, analytics, and customer data
- Supplier, 3PL, warehouse, software, and advertising accounts
Industry-Specific Red Flags
Treat each warning as a verification trigger rather than an automatic accusation. Quantify revenue, margin, downtime, replacement, remediation, penalty, or continuity exposure only when support exists.
- Seller assumes a marketplace account can transfer without written confirmation
- Profit excludes advertising, returns, storage, freight, or owner labor
- Inventory value ignores age, restrictions, or landed cost
- One platform, SKU, supplier, or ad channel drives the business
Buyer Closing Controls
- Reconcile current financial performance immediately before closing
- Confirm licenses, consents, insurance, lease, key staff, and operational accounts
- Obtain payoff and release evidence for relevant liens
- Complete inventory, asset-condition, and working-capital procedures
- Version the report and list every change since the LOI
- Escalate legal, accounting, tax, environmental, insurance, or technical issues to qualified advisers
Official Sources and Verification Routes
Use the exact legal entity, address, filing number, license number, facility identifier, or carrier identifier shown in the source. Access, coverage, fees, and update timing vary.
Frequently Asked Questions
What should I verify first when buying an E-commerce or Amazon FBA Business?
Confirm the exact entity, reproduce the earnings figure, identify owner-dependent work, and verify the licenses, property rights, people, assets, and accounts required to operate on day one.
Can public records replace seller documents?
No. Public records can corroborate identity and surface specified filings or compliance history, but company financials, contracts, customers, employees, assets, and operating records remain essential.
What does a clear report guarantee?
It documents the sources searched, identifiers used, retrieval times, results, limitations, unresolved items, and next steps. It does not guarantee that no risk or undisclosed liability exists.
