Before you acquire an Amazon FBA brand, Shopify store, or multi-channel DTC business, use this checklist to verify every revenue source, platform dependency, supplier relationship, and financial claim — so you close with confidence and avoid costly surprises.
Acquiring an e-commerce business in the $1M–$5M revenue range offers significant upside — but also carries risks that don't exist in traditional brick-and-mortar acquisitions. Platform dependency, traffic source fragility, inventory inaccuracies, and undisclosed account health issues can turn a promising acquisition into a turnaround project within months of closing. This checklist walks through every critical area of e-commerce due diligence: financial verification, traffic and channel analysis, Amazon and marketplace health, supplier agreements, inventory accuracy, technology stack, team and SOPs, and legal protections. Use it to structure your QoE requests, seller conversations, and third-party advisor reviews before signing a purchase agreement.
Verify the accuracy and sustainability of revenue, margins, and discretionary earnings across all selling channels. E-commerce P&Ls frequently mix platform fees, ad spend, returns, and COGS in ways that obscure true profitability.
Request 3 years of accrual-based P&L statements and reconcile against tax returns
Cash-basis or seller-prepared financials are common in founder-operated e-commerce businesses and often overstate SDE by misclassifying personal expenses or omitting platform fee accruals.
Red flag: Tax returns show materially lower revenue or net income than the seller-prepared P&L with no explanation
Obtain channel-level revenue breakdowns for Amazon, Shopify, wholesale, and any other platform
Aggregate revenue figures hide concentration risk. A business earning 90% of revenue through Amazon Seller Central is far more exposed to platform disruption than a diversified multi-channel operator.
Red flag: Seller cannot provide channel-level breakdowns or consolidates all revenue into a single line item
Validate Amazon and Shopify gross revenue against platform payout reports and bank deposits
Sellers sometimes report gross merchandise value rather than net revenue after platform fees, refunds, and chargebacks, inflating the top line by 15–30%.
Red flag: Bank deposits are consistently lower than reported net revenue with no reconciling items provided
Analyze monthly revenue and margin trends over the trailing 24 months
E-commerce businesses are susceptible to rapid revenue deterioration from algorithm changes, competitor entry, or supply chain disruption. Trailing trends reveal whether the business is growing, plateauing, or declining.
Red flag: Revenue or gross margin has declined in 3 or more of the last 6 months with no credible explanation
Reconstruct EBITDA by normalizing owner salary, one-time expenses, and add-backs
Seller add-backs in e-commerce frequently include personal travel, home office, vehicle expenses, and one-time inventory write-offs. Each add-back must be documented and defensible for SBA lender underwriting.
Red flag: Add-backs exceed 20% of stated EBITDA or include recurring operating expenses recharacterized as one-time items
Review advertising spend as a percentage of revenue and calculate true contribution margin
Many e-commerce businesses are profitable on paper but cash-flow negative when ad spend is accurately allocated. Contribution margin after COGS and variable marketing costs is the real profitability metric.
Red flag: Gross margin appears strong but contribution margin after paid ads drops below 15%, indicating a business propped up by scaling ad spend unsustainably
Verify return rates, refund rates, and chargeback history by channel and SKU
High return rates signal product quality issues, misleading listings, or fragile customer satisfaction — all of which compress net revenue and create ongoing operational liability.
Red flag: Return rate exceeds 10% on any core SKU or chargeback rate approaches platform warning thresholds
Confirm working capital requirements including inventory financing cycles and seasonal cash needs
E-commerce acquisitions often require significant post-close working capital for inventory replenishment, particularly for businesses with 90–120 day overseas lead times. Buyers frequently underestimate this need.
Red flag: Seller cannot quantify seasonal inventory investment requirements or has outstanding inventory financing obligations not disclosed in the LOI
Understand where customers come from, how stable those sources are, and what it costs to acquire them. E-commerce businesses built primarily on paid traffic carry significantly higher risk than those with strong organic or direct channels.
Request 24 months of Google Analytics or equivalent data with full channel attribution
Traffic source data reveals whether the business has built durable demand through SEO and brand recognition or is entirely dependent on paid advertising to maintain revenue.
Red flag: Seller cannot grant read-only analytics access or the data shows paid traffic exceeding 70% of total sessions with no organic growth trend
Analyze organic search traffic trends and identify top-ranking keywords and pages
Organic traffic represents low-cost, sustainable customer acquisition. A Shopify or DTC store with strong SEO equity is significantly more defensible than one reliant on Meta or Google Ads.
Red flag: Organic traffic has declined more than 20% year-over-year or the business has no meaningful keyword rankings outside branded terms
Review paid advertising account access across Meta, Google, Amazon Ads, and TikTok
Ad account history, ROAS trends, and audience data are transferable assets. Declining ROAS over the trailing 12 months signals either market saturation or creative fatigue that will require increased spend post-close.
Red flag: ROAS has declined more than 30% over the trailing 12 months or ad accounts have been suspended or flagged for policy violations
Evaluate email and SMS list size, engagement rates, and revenue attribution
A large, engaged email and SMS subscriber base is one of the highest-value digital assets in an e-commerce acquisition — representing owned, low-cost customer retention that survives platform changes.
Red flag: Email list has fewer than 10,000 subscribers for a $2M+ revenue business, or open rates are below 15%, suggesting an unengaged or purchased list
Calculate customer acquisition cost (CAC) and lifetime value (LTV) by channel and cohort
LTV-to-CAC ratio determines whether the business can profitably grow. An LTV:CAC ratio below 2:1 indicates the business is acquiring customers at a loss and cannot scale without margin compression.
Red flag: LTV:CAC ratio is below 2:1 or seller cannot produce cohort-level data to support LTV claims
Assess repeat purchase rate and customer retention by SKU and product category
Repeat purchase rate directly impacts CAC payback period and long-term profitability. Consumable or subscription-adjacent products with high repurchase rates command premium multiples for good reason.
Red flag: Repeat purchase rate is below 20% for a consumable or replenishable product category, or repeat customers account for less than 30% of total revenue
Review Amazon search rank stability and organic keyword rankings for core ASINs
Amazon organic rank is a revenue-generating asset. Rank volatility signals algorithmic vulnerability or review manipulation — both of which can collapse sales overnight without warning.
Red flag: Top ASINs show significant rank fluctuations in the trailing 90 days or organic rank is propped up by heavy PPC spend rather than sustained sales velocity
Platform account health is existential for Amazon-dependent businesses. A suspended or restricted account can eliminate the majority of revenue within 24 hours of close. Conduct exhaustive account health review before signing.
Obtain full read-only access to Amazon Seller Central account and review account health dashboard
Account Health Rating (AHR), policy violation history, and active warnings are not visible outside Seller Central. A seller summarizing this verbally is insufficient — you must see the actual dashboard.
Red flag: Seller refuses or delays granting Seller Central access, or the account health dashboard shows an AHR below 200 or active policy warnings
Review all active and closed buyer complaints, A-to-Z claims, and chargeback history
Patterns of A-to-Z claims reveal product quality, fulfillment, or authenticity issues that Amazon monitors closely. Elevated claim rates increase suspension risk and signal operational problems that will transfer to the buyer.
Red flag: A-to-Z claim rate exceeds 1% or there are unresolved claims outstanding at time of due diligence
Audit review integrity across all core ASINs for manipulation indicators
Review manipulation — including incentivized reviews, review swaps, or purchased reviews — is an Amazon Terms of Service violation that can result in ASIN suppression, account suspension, or permanent ban.
Red flag: Review velocity spikes that don't correspond to sales spikes, unusual review-to-sales ratios, or third-party tools flagging suspected manipulation on core ASINs
Confirm the seller account is in good standing and transferable under Amazon's account transfer policies
Amazon's Terms of Service technically prohibit account sales, but the practical transfer of account control is standard in acquisitions. However, some accounts are flagged as non-transferable due to prior violations.
Red flag: Account was previously suspended, reinstated under appeal, or is linked to other accounts with enforcement history that could trigger cross-account suspension
Review FBA inventory levels, stranded inventory, and unfulfillable inventory reports
Stranded or unfulfillable inventory represents cash tied up in non-revenue-generating stock that you will absorb at closing. It also indicates poor inventory management practices that may continue post-close.
Red flag: Stranded or unfulfillable inventory exceeds 10% of total FBA inventory value or has been accumulating for more than 90 days without resolution
Evaluate any additional marketplace presence on Walmart, eBay, or Target+ and review those account health metrics
Secondary marketplace revenue may appear in the P&L but carry hidden account health risks. Marketplace diversification is only a strength if those accounts are clean and transferable.
Red flag: Seller cannot provide account health data for any marketplace contributing more than 10% of revenue
Confirm Brand Registry enrollment and review brand protection history
Amazon Brand Registry provides critical tools to fight hijackers and counterfeiters. A brand not enrolled in Brand Registry is significantly more vulnerable to listing takeovers that can destroy review history and organic rank.
Red flag: Brand is not enrolled in Brand Registry despite having an active trademark, or there is a history of unresolved hijacker incidents on core ASINs
Inventory is frequently the largest balance sheet asset in an e-commerce acquisition and the most commonly misrepresented. Supplier concentration and lead times determine whether the business can sustain growth post-close.
Conduct an independent physical or third-party inventory count and reconcile against seller's stated value
Inventory valuations are often inflated to increase purchase price. Aged, slow-moving, or obsolete inventory should be valued at net realizable value — not cost — and excluded from the business valuation goodwill calculation.
Red flag: Seller's stated inventory value cannot be reconciled against purchase orders, warehouse counts, or FBA inventory reports with a variance greater than 5%
Analyze inventory turnover by SKU and identify aged stock older than 180 days
Slow-moving inventory consumes working capital and generates ongoing FBA storage fees. Excess aged inventory may need to be liquidated post-close at a loss, negatively impacting first-year cash flow.
Red flag: More than 20% of inventory by value has been sitting for 180+ days or Amazon has issued long-term storage fee notices on a significant portion of FBA stock
Review all supplier agreements, payment terms, exclusivity clauses, and minimum order quantities
Supplier relationships are often informal in founder-operated e-commerce businesses. The absence of written agreements means pricing, terms, and exclusivity can change immediately after ownership transfers.
Red flag: Key suppliers operate on handshake agreements with no written contracts, or exclusive supply arrangements are personal to the seller and not assignable to a buyer
Identify supplier concentration risk and evaluate backup supplier options
A business sourcing 80%+ of revenue-generating products from a single overseas manufacturer is one tariff increase, port delay, or factory closure away from a revenue collapse.
Red flag: A single supplier accounts for more than 60% of COGS and no alternative sourcing options have been identified or tested
Review historical lead times and assess current supply chain disruption risk
Post-close inventory planning depends on realistic lead times. Businesses with 90–120 day overseas lead times require significant working capital pre-commitment and carry elevated stock-out risk.
Red flag: Lead times have increased materially in the trailing 12 months with no mitigation plan, or the business has experienced at least one significant stock-out event in the trailing year
Confirm product formulations, manufacturing specifications, and product quality documentation are owned by the business
Many manufacturers retain product formulations as leverage. If the supplier owns the formulation, they can produce and sell an identical product to competitors — eliminating your brand's moat entirely.
Red flag: Seller cannot produce written documentation confirming the business owns product specifications, formulations, or tooling used in manufacturing
Review 3PL or fulfillment center agreements, service levels, and transition risk
Third-party logistics providers hold significant operational leverage. Contract terms, SLA commitments, and ownership-change clauses must be reviewed before closing to avoid fulfillment disruption.
Red flag: 3PL agreement contains change-of-control termination clauses or the relationship is informal with no written SLA defining pick/pack accuracy or ship times
Brand equity and IP ownership determine defensibility and transferability. In e-commerce, trademark registration, domain ownership, and copyright protection are the primary assets that distinguish an acquisition from a commodity resale business.
Verify active trademark registrations for the brand name, logo, and any sub-brands across relevant classes
A trademark registration is the foundation of brand defensibility on Amazon and in general commerce. Without it, competitors can legally use confusingly similar brand names and undercut the business you just acquired.
Red flag: Brand has been operating for 3+ years with no trademark filing, or a trademark application is pending but not yet registered — creating uncertainty about IP ownership at close
Confirm ownership of all domain names, social media handles, and digital brand assets
Domain names and social media accounts are often registered in a founder's personal name rather than the business entity. These must be transferred as part of the acquisition to avoid post-close ownership disputes.
Red flag: Core domain or social media accounts are registered to the seller personally with no assignment agreement included in the purchase agreement
Review any pending or threatened litigation, regulatory actions, or Amazon IP complaints
IP infringement claims — particularly patent or trademark disputes — can result in forced product listing removal, legal liability transfer to the buyer, and significant legal costs.
Red flag: Seller has received DMCA takedown notices, received cease-and-desist letters, or has unresolved Amazon IP complaint strikes on any core ASIN
Confirm product compliance with FDA, CPSC, FTC, or other applicable regulatory requirements by category
E-commerce products — particularly supplements, cosmetics, children's products, and electronics — carry regulatory compliance obligations. Non-compliant products can be delisted, recalled, or trigger personal liability.
Red flag: Seller cannot produce lab testing reports, safety certifications, or compliance documentation for products in regulated categories
Review privacy policy, terms of service, and data handling practices for GDPR and CCPA compliance
Customer email lists and purchase data are valuable acquisition assets — but only if collected in compliance with applicable privacy laws. Non-compliant data practices create regulatory liability for the buyer.
Red flag: Privacy policy has not been updated since 2018 or the business has no documented consent process for email collection and marketing
Audit any affiliate, influencer, or referral agreements for transferability and FTC compliance
Influencer-driven revenue is a growing e-commerce channel but carries FTC disclosure compliance risk. Informal affiliate arrangements that are personally tied to the seller may not survive an ownership change.
Red flag: Affiliate program payments are made personally by the seller with no formal agreement, or influencer posts do not include required FTC disclosure language
Verify that the technology stack is stable, documented, and transferable — and that operations can run without the seller after a reasonable transition period. Owner-dependency is one of the most common post-close surprises in e-commerce acquisitions.
Audit the full technology stack including Shopify, ERP, inventory management, email platform, and analytics tools
Technology costs are frequently underrepresented in seller financials. Subscription tools, app fees, and developer costs that were informal or absorbed personally by the seller become real operating expenses post-close.
Red flag: Multiple critical operational tools are on the seller's personal accounts or credit cards, with no business-level billing that can be transferred
Request and review all documented SOPs covering order fulfillment, customer service, inventory reordering, and listing management
The presence of documented SOPs is the single best proxy for owner-independent operations. Without them, institutional knowledge walks out the door with the seller and post-close operational risk is high.
Red flag: Seller cannot produce written SOPs for any core operational process, or states that all institutional knowledge resides with them personally
Evaluate the existing team structure including virtual assistants, contractors, and full-time employees
The team is a critical operational asset. Key employees or contractors may leave post-sale due to uncertainty, and their retention — or replacement — must be factored into transition planning and cost modeling.
Red flag: All operational functions are performed by the seller with no support team, or key contractors have expressed unwillingness to continue under new ownership
Confirm seller's willingness and ability to provide a structured post-close transition of 60–90 days minimum
Supplier introductions, platform account transitions, team handoffs, and operational knowledge transfer cannot happen in a two-week transition. A compressed transition period significantly increases post-close risk.
Red flag: Seller is only willing to provide a 30-day or less transition or has pre-existing commitments that will prevent meaningful involvement in post-close knowledge transfer
Review customer service response times, satisfaction metrics, and open support ticket history
Customer service quality directly impacts Amazon seller metrics, Shopify reviews, and repeat purchase rates. Deferred support tickets and unresolved complaints represent post-close liability.
Red flag: Customer service is handled personally by the seller with no documented process, or there is a backlog of unresolved support tickets that could affect platform metrics at close
Assess the durability and diversification of revenue across products, customers, and channels. Concentration risk in any single dimension — one SKU, one platform, one wholesale account — is a primary valuation and risk factor.
Calculate revenue concentration by SKU and identify the top 5 products as a percentage of total revenue
A business generating 70%+ of revenue from a single SKU is highly vulnerable to a competitor launch, supply disruption, or listing removal. SKU concentration is a primary risk factor in e-commerce acquisitions.
Red flag: A single SKU accounts for more than 50% of total revenue with no pipeline of complementary products to diversify the revenue base
Identify any wholesale or B2B customer accounts and assess concentration and contract status
Wholesale accounts can represent significant revenue concentration. Buyer relationships may be personal to the seller, and losing one or two key accounts post-close can materially impact projected earnings.
Red flag: A single wholesale account represents more than 20% of revenue with no written purchase agreement or minimum order commitment
Analyze subscription revenue or auto-replenishment programs as a percentage of total revenue
Recurring subscription revenue is the highest-quality revenue in e-commerce — it provides predictable cash flow, high LTV, and natural defensibility. Its presence or absence materially affects valuation.
Red flag: Seller claims subscription revenue but cannot produce subscription cohort data, churn rates, or recurring revenue reports from their platform
Review seasonality patterns and assess the impact of peak periods on annual revenue and working capital
E-commerce businesses often generate 30–50% of annual revenue in Q4. A business acquired in January may appear far more profitable than it will be in months 2–8, creating cash flow surprises for underprepared buyers.
Red flag: More than 40% of annual revenue is concentrated in a single quarter with no documented working capital plan for funding pre-season inventory purchases

Vetted targets with diligence packages — skip the cold search.
Most e-commerce acquisitions in this range require 30–60 days of active due diligence from LOI execution to purchase agreement signing. Amazon-heavy businesses often take longer due to the complexity of account health review, inventory reconciliation, and FBA data analysis. Plan for at least 45 days if SBA financing is involved, as lender underwriting adds additional document review time on top of your business due diligence.
Traffic source dependency is the most frequently underestimated risk. Many buyers focus heavily on revenue and margin verification but fail to stress-test whether the business can maintain customer acquisition if paid ad costs increase 20–30% or if a Meta or Google algorithm change reduces ad efficiency. A business that looks profitable at current ad spend can become unprofitable quickly if customer acquisition costs rise — which has been the trend since iOS 14 privacy changes in 2021.
Yes. E-commerce businesses are SBA 7(a) eligible as long as the business meets standard SBA eligibility criteria — including being a for-profit U.S. business, operating for at least 2 years, and having clean financials that support debt service coverage. Most SBA lenders will require a Quality of Earnings report and will scrutinize platform dependency and revenue sustainability carefully. Amazon-only businesses with no diversification may face more conservative underwriting. Expect SBA financing to cover 80–90% of the purchase price with the seller or buyer covering the remaining 10–20%.
Inventory should be valued at net realizable value — not cost — and negotiated as a separate line item from the business purchase price. Aged inventory (180+ days), slow-moving SKUs, and damaged or unsellable stock should be excluded or heavily discounted. The business enterprise value (expressed as a multiple of SDE or EBITDA) reflects the earnings power of the business, while inventory is an additional working capital asset you are acquiring. Commingling the two inflates the effective multiple and distorts your ROI calculation.
Amazon does not have a formal account transfer process and technically prohibits the sale of accounts in its Terms of Service. In practice, acquisitions are structured as entity purchases (buying the LLC or corporation that owns the account) or through a gradual transition where the buyer establishes operational control. Many buyers work with Amazon's M&A team for larger acquisitions, or proceed with asset purchases and create new accounts — though new accounts lose review history and organic rank. This is one of the highest-risk operational elements of any Amazon acquisition and should be reviewed with an attorney experienced in e-commerce M&A.
At the LOI stage, prioritize the following: 3 years of P&L statements and tax returns, trailing 12 months of channel-level revenue reports from each platform, Google Analytics or equivalent read-only access, Amazon Seller Central read-only access, supplier agreements and key vendor contact information, and inventory aging report. Full document requests — including legal agreements, employee records, and IP registrations — are typically exchanged after LOI execution and during the formal due diligence period.
A defensible e-commerce brand typically has at least three of the following: a registered trademark and active brand enforcement history, proprietary product formulations or manufacturing specifications owned by the business, a customer email and SMS list with strong engagement metrics, organic search traffic driven by genuine brand demand rather than generic keywords, a patent or exclusive licensing agreement covering core products, and demonstrable customer loyalty reflected in repeat purchase rates above 30%. White-label products with no differentiation and no brand investment are commodities — not moats — and should be valued accordingly.
In the lower middle market e-commerce space, seller financing typically represents 10–20% of the total purchase price, held over 2–3 years at 6–8% interest. Some deals include performance-based conditions where seller note payments are contingent on the business maintaining a minimum revenue or EBITDA threshold in the 12–24 months post-close. Seller financing is often required by SBA lenders as a condition of the deal structure. For buyers, it serves as a meaningful alignment mechanism — a seller who holds a note has real financial incentive to ensure a clean transition and honest representation of business performance.
