The M&A Playbook for E-Commerce Companies: What Buyers Look For in Accounting and Tax
E-commerce M&A has matured. Buyers still care about growth and brand, but they now spend just as much time on how the business operates day to day, particularly its financial reporting and tax.
If a sale is something you may consider down the road, knowing what buyers focus on can help you feel more prepared when the time comes.
Diligence Readiness: Why It Matters
Being “diligence-ready” simply means someone unfamiliar with your business can understand how your financials and operations work.
Where Buyers Typically Focus
1. Accounting and Financial Reporting
Buyers look closely at how your financials are put together, especially areas that vary across e-commerce businesses:
- Revenue Recognition (ASC 606): How marketplace sales are presented, when revenue is recognized, and how returns are handled.
- Inventory Accounting: How inventory is valued, whether reserves are recorded for slow-moving or obsolete items, and how costs like freight, duties, and tariffs are treated.
- Quality of Financial Reporting: Reviewed or audited financials are often preferred, along with a clean cap table, a clear equity history you can trace from day one, and clean classification between debt and equity.
- Quality of Earnings: Buyers normalize EBITDA for owner add-backs, one-time costs, and other non-recurring items to understand the true run-rate margin. Be ready to support each adjustment, since this is often where the deal gets priced.
- Net Working Capital: Most deals set a working capital target at close. How inventory and payables are normalized into that target is frequently the largest post-LOI negotiation, especially for an inventory-heavy business.
2. Tax Considerations
E-commerce businesses often grow across many jurisdictions without realizing the tax footprint that creates. Buyers typically want to understand:
- State Income Tax (PL 86-272): These protections historically limited when states could tax out-of-state sellers whose only activity was shipping physical goods into the state. As activity has shifted online, states have begun reinterpreting those rules, and certain website features or customer interactions can affect whether the protection still applies.
- Sales and Use Tax: Marketplaces usually collect sales tax on the sales they facilitate, but sales through your own direct-to-consumer channels are typically your responsibility once you cross a state’s economic nexus threshold. Companies can also owe use tax on certain purchases or expenses. Buyers will also want historical exposure quantified and a cleanup path, such as voluntary disclosure agreements; any unresolved exposure is often covered by an escrow or holdback at close.
- Property in a State (FBA Inventory and Retail Fixtures): Physical property the company owns can create a presence in a state, even without an office or employees there. With Fulfillment by Amazon (FBA), inventory is stored across multiple states. Similarly, in-store displays, endcaps, and fixtures sitting on a retailer’s floor can count. In both cases, that property may create income and sales and use tax filing requirements.
- International Expansion: Selling into countries like Canada or across the UK and EU can introduce indirect tax requirements such as GST/HST or VAT once certain thresholds are met.
3. Business and Operating Metrics
Beyond the financial statements and tax filings, buyers look at how the business actually performs:
- Customer and Channel Concentration: Heavy reliance on a single marketplace (such as Amazon), platform, or a handful of SKUs is a top e-commerce risk and a real valuation driver. Buyers want to see diversification, or a credible plan to get there.
- Unit Economics: Buyers diligence CAC, LTV, AOV, repeat-purchase rate, and contribution margin as closely as the financials. Define these consistently and be able to show how they trend over time.
The Takeaway
Diligence readiness is less about avoiding issues entirely and more about being prepared to walk through them clearly.
If a sale becomes a realistic possibility, early planning can also help preserve tax benefits like Qualified Small Business Stock (QSBS), which can meaningfully improve after-tax proceeds for companies. Because that benefit depends on entity structure and holding periods, it’s one of the clearest examples of why planning years ahead of a deal matters.
