How to buy an e-commerce business

Why e-commerce is both attractive and fragile

E-commerce businesses check a lot of boxes buyers like: low headcount, no real estate, cash flow you can verify against a live dashboard, and a purchase price that's often smaller than a comparable brick-and-mortar business with the same earnings. A solo operator can run a seven-figure-revenue Shopify or Amazon brand with a 3PL, a couple of virtual assistants, and a laptop.

The trade-off is that almost none of the infrastructure the business runs on is actually owned by the seller. The Amazon listing lives inside Amazon's marketplace. The ad accounts live inside Meta's and Google's systems. The supplier relationship lives in a group chat with a factory in another country. A buyer isn't just buying revenue, they're buying continued access to every platform that revenue depends on, and that access is the part diligence has to prove out.

Platform mix: Shopify DTC vs. Amazon vs. multi-channel

Where the revenue comes from changes both the risk profile and the multiple a buyer should pay.

• Shopify / DTC. The buyer owns the customer relationship, the email list, and the checkout data outright. It's the most "ownable" model, but customer acquisition cost is entirely the buyer's problem from day one, and revenue is more exposed to ad-platform volatility.
• Amazon / marketplace. Amazon supplies the traffic, the trust, and often most of the reviews, which is exactly why it's rented, not owned. A single account suspension, a lost Buy Box, or a policy change can zero out revenue overnight, and none of it is within the new owner's direct control.
• Multi-channel. Brands selling across Shopify, Amazon, Walmart Marketplace, TikTok Shop, and wholesale spread the platform risk. It's harder to operate but a materially safer acquisition, no single account outage or policy shift can take out the whole business.

Alongside channel mix, weigh customer concentration (are a handful of wholesale or B2B accounts carrying the business?) and the health of the email list / CRM, a large, engaged list is a real, transferable asset that reduces dependence on any single ad platform, and it's one of the few growth levers a new owner fully controls from day one.

Supplier and SKU concentration

Product businesses live or die on the supply chain, and it's the part first-time buyers underwrite the least. Pull the SKU-level P&L: if two or three SKUs generate the majority of profit, the business is really a bet on those SKUs continuing to sell and continuing to be manufacturable at the same cost. Then look at the supplier side of the same question, is there a written supplier agreement, or does the relationship exist because the factory owner personally likes the seller? Confirm minimum order quantities, lead times, whether pricing is locked or subject to renegotiation at ownership change, and whether the seller has a backup supplier if the primary one fails.

You're not buying a store. You're buying a rented shelf on someone else's marketplace, the reviews are the only thing that make it worth renting.

Trademark and Brand Registry status matter here too: a registered trademark tied to the brand (not the individual seller) is what makes Amazon's Brand Registry protections, A+ content, and enhanced listings transferable to a new owner in the first place.

Advertising account risk: the part generic playbooks skip

This is the single most e-commerce-specific diligence item, and it's easy to miss if you're used to buying a service business.

• Meta (Facebook/Instagram) Ads. You aren't transferring "ownership" the way you'd transfer a domain, you're moving the ad account between Business Managers, which requires the account to be in good standing with no unpaid balance or restriction, and personal ad accounts can't be moved this way at all. Losing the ad account also risks losing pixel data and audience history that took years to build.
• Google Ads. Ownership transfers by adding the buyer as an admin in the Access & Security section and transferring control from there, more mechanical than Meta's process, but it still needs to happen before or at close, not after.
• Amazon Seller Central / FBA. Amazon treats seller accounts as effectively non-transferable: when ownership of the business changes, the buyer typically has to open a new Seller Central account, with the brand, listings, and inventory reassigned and Brand Registry re-verified against the purchase agreement and supporting documents. Reviews live on the listing (the ASIN), not the account, so they generally carry over once the listing itself is transferred, but the account's age, metrics, and selling history do not.

How e-commerce deals get priced

Online-business brokers price differently from Main Street business brokers, and it's worth understanding both conventions because they converge on a similar number.

The reason the two conventions look different at first glance is what sits inside the number. Brokers who quote "30x, 45x monthly net profit" are usually multiplying reported net profit before a buyer adds back the owner's replacement wage and discretionary perks; once you rebuild true SDE, the effective multiple compresses toward the middle of that range, which is exactly where our 3.33× anchor and BizBuySell's 3.43× median sit. Inventory is priced separately from this multiple and added to the purchase price at cost, a store with $150,000 SDE at 3.33× is a $499,500 business value, plus whatever clean, sellable inventory sits in the warehouse at closing. Content-heavy or "aged" brands with strong organic traffic and low ad dependence command the top of these ranges; single-SKU, single-channel, ad-dependent stores sit at the bottom.

Diligence that matters in an e-commerce deal

Skip the generic checklist. In an online business, five things move the needle:

• Verify revenue at the source, not the pitch deck. Get read access to Shopify Analytics, Amazon Seller Central reports, and Stripe/payment-processor dashboards, and reconcile them against two to three years of tax returns and bank deposits. A screenshot proves nothing; a login does.
• Refund and chargeback rates. Overall e-commerce return rates run roughly 19%, 20% of orders per the NRF's 2025 Retail Returns Landscape, varying widely by category (apparel 20%, 40%, electronics 8%, 15%). Average chargeback rates moved between about 0.17% and 0.26% of transactions through 2025. Numbers well above category norms point to product-quality, listing-accuracy, or fraud problems.
• Inventory valuation. Inventory is typically priced at landed cost on top of the SDE multiple, not baked into it, but only "clean, salable" inventory counts. Stock that's been sitting 180+ days is usually excluded or heavily discounted in the pre-close inventory count.
• Review authenticity. A brand with hundreds of reviews and a suspiciously flat 4.9-star average is worth a manual read-through. Manufactured reviews are a policy violation that can trigger a suspension after you own the account.
• Trademark, product liability, and returns exposure. Confirm the trademark is registered to the entity being sold (not a departing individual), check for any open product-liability claims, and understand the return/warranty obligations you're inheriting.

How to structure the deal

Because so much of the value sits inside third-party platforms, smart structures protect the buyer against account and revenue risk in the weeks after close:

• Holdback or escrow tied to account health. A slice of the price (commonly 10%, 20%) is held back for 30 to 90 days to confirm no suspension, chargeback spike, or platform policy issue surfaces once the transfer is public.
• Structured transition period. The seller stays on for 30 to 60 days to walk through supplier contacts, ad account handoffs, and Seller Central re-verification, this is where most of the platform risk in the deal actually gets retired.
• Inventory true-up at close. A physical or FBA-reported count on closing day sets the final inventory add-on, so neither side is guessing.
• IP and account assignment as closing conditions. Trademark assignment, Brand Registry transfer, and ad account moves should be conditions of funding, not promises to complete "after" close.

Financing an e-commerce business

E-commerce businesses are financeable with an SBA 7(a) loan, plan for roughly 10% down and a DSCR of 1.15×, 1.25×, but lenders underwrite them more cautiously than a service business. SBA financing for an online business hinges on verifiable, transferable cash flow and a real, multi-year operating history; a store that just launched, or one with financials that can't be reconciled to bank statements and tax returns, will struggle to qualify regardless of how good the Amazon rank looks. Bring account-level exports, not just aggregated reports, to the lender conversation, and model the payment before you write an offer in the valuation calculator.
