Buying an E-Commerce Business
The post-aggregator market prices on sustainable profit, not growth stories. How FBA and DTC brands trade, why channel concentration sets the discount, and the inventory and supplier questions that decide whether the margin is real.
A Market That Already Had Its Bubble
E-commerce acquisitions went through a full cycle: aggregators bid FBA brands to peak multiples through 2021, then the correction repriced everything. 2025 to 2026 guidance describes buyers underwriting 30% to 40% below peak-era multiples, on sustainable contribution margin rather than revenue growth or pandemic spikes. For a searcher that history is useful: sellers anchored to 2021 stories are identifiable, and the market's scar tissue now does some of your diligence for you.
What Online Brands Trade For
2025 to 2026 roundups put Amazon-FBA-dependent businesses near 2.5x to 4x SDE and Shopify-led DTC brands around 3x to 4.5x, with repeat-purchase niches at the top and hybrid multi-channel brands commanding the premium tier. Channel concentration is priced explicitly: single-channel dependence is reported to cost multiple turns of discount while diversified revenue adds them. Sub-$5M-revenue deals underwrite on SDE; larger teams shift to EBITDA.
Platform Risk Is the Core Risk
An FBA business lives on an account it does not control: suspension, category and fee changes, listing hijacks, and review actions are existential events, which is exactly why FBA-heavy books price below diversified peers. Read the account health history, brand-registry status, and any past suspensions personally. The same logic applies in softer form to DTC brands built entirely on one ad channel, where an algorithm or cost shift rewrites the P&L overnight.
Inventory and the Real Purchase Price
Inventory is usually purchased at close on top of the headline price, which makes the real check bigger than the multiple suggests. Age the inventory honestly (dead stock is not an asset), reconcile landed costs including freight and tariffs against the margin story, and map the supplier base: a single overseas factory with no tooling ownership or backup source is a concentration risk exactly as serious as a top customer, and tariff exposure belongs in your model, not a footnote.
What to Verify in Diligence
Contribution margin by SKU and channel after fully loaded ad costs, since blended gross margin hides losers; ad efficiency trends and how much revenue is bought versus organic; review and ranking durability; email and customer-list quality for DTC; software subscriptions and app-stack transfer; any trademark and brand-registry assets, which are much of what you are actually buying; and the operator hours the seller really works, because 'passive' listings routinely conceal a full-time job.
Financeability Notes
Online businesses finance less cleanly than main-street ones: collateral is thin, history is often short, and some lenders decline the category, though SBA deals close regularly for established brands with documented earnings. Expect more scrutiny of earnings durability and inventory quality, and consider that marketplace escrow norms and migration processes (account transfers, brand registry) are part of closing mechanics. Model debt service on post-correction earnings with ad costs at current, not historical, rates.
What the Data Says
2025 to 2026 roundups place FBA-dependent businesses near 2.5x to 4x SDE and Shopify-led DTC brands around 3x to 4.5x, with repeat-purchase niches at the top; channel concentration is priced explicitly, with single-channel dependence discounted and multi-channel mixes earning premiums.
Post-aggregator analysis describes buyers underwriting 30% to 40% below peak-era multiples, pricing sustainable contribution margin rather than revenue growth or pandemic-period spikes.
Sub-$5M-revenue online businesses underwrite on SDE while larger, team-run brands shift to EBITDA, a split that determines which multiples are even comparable across listings.
