E-commerce businesses can look deceptively simple — traffic comes in, orders go out, margins show in the accounts. But buyers know that traffic can be rented, suppliers can be lost, and an algorithm change can cut revenue overnight. Your job as a seller is to show that the business is more durable than that.
Quick Answer
To sell an e-commerce business in the UK, prepare platform sales reports, traffic analytics, paid advertising data, a clear stock valuation, supplier terms, the fulfilment process, customer data and email list consents, and evidence of IP and product image ownership. Buyers will scrutinise whether revenue is sustainable, whether the supply chain is secure, and whether the digital assets — domain, platform accounts, brand, email list — can transfer cleanly.

What makes selling an e-commerce business different?
E-commerce businesses are digital-first — their assets are largely intangible, their revenue is platform-dependent, and their customer relationships exist in data rather than in conversations. This creates a due diligence process that looks quite different from a traditional bricks-and-mortar business sale.
A buyer of a physical business walks around the premises, inspects the equipment and talks to the staff. A buyer of an e-commerce business logs into Google Analytics, reads platform dashboards, exports the email list, reviews supplier contracts and checks whether the domain and platform account are in the seller's name and can be transferred.
The central question in every e-commerce acquisition is the same: is the revenue real, repeatable and transferable? Revenue that depends on a single paid advertising channel, a single supplier relationship or the seller's personal involvement in content creation is more fragile than revenue from organic search, direct customers and systemised operations.
A buyer may be acquiring:
The domain name and website
Platform accounts — Shopify, WooCommerce, Amazon Seller Central, eBay, Etsy
Brand name and trademarks
Product listings and product photography
Email list and SMS list
Customer database
Social media accounts and following
Paid advertising accounts — Google Ads, Meta Ads, TikTok Ads
SEO rankings and backlink profile
Supplier relationships and agreements
Stock — finished goods, raw materials, packaging
Fulfilment arrangements — in-house, third-party logistics (3PL) or dropship
Product designs, formulations or proprietary IP
Review profiles — Trustpilot, Google, Amazon seller feedback
Staff or freelancers
Each of these elements contributes to value — and each requires specific preparation and verification.
What type of e-commerce business are you selling?
E-commerce covers a wide range of models. Understanding which model describes your business helps buyers assess risk and price accurately.
Direct-to-consumer (DTC) via owned website.The business sells its own products through a branded website — typically Shopify or WooCommerce. Revenue comes from a mix of organic search, paid advertising, email marketing and social media. Buyers value owned audience (email list, SEO rankings) over rented audience (paid ads) because owned audience is more durable.
Amazon FBA (Fulfilment by Amazon).Products are sold through Amazon, with stock held in Amazon's fulfilment centres. Amazon picks, packs and ships orders. Revenue is platform-dependent — Amazon can change fees, rankings or policies in ways that directly affect profitability. Buyers will review Amazon Seller Central data in detail.
Multi-channel.The business sells across multiple platforms — owned website, Amazon, eBay, Etsy, retail partners. Multi-channel diversification can reduce platform risk but increases operational complexity. Buyers will assess the revenue split across channels and the relative margin by channel.
Dropship.Products are listed and sold online but never held in stock — orders are fulfilled directly by a supplier. Margins are typically lower and competition is higher, but working capital requirements are minimal. Buyers will assess supplier reliability, exclusivity (or lack of it) and whether the product range is genuinely differentiated.
Wholesale / B2B e-commerce.The business sells to trade customers online, often on account terms. Revenue can be more recurring and predictable than consumer DTC, but working capital requirements are higher because of credit terms.
Own-brand / white-label.The business sources generic products and sells them under its own brand. Brand, packaging and product positioning are the differentiation. IP ownership of the brand and product imagery is critical.
Marketplace seller.The business operates primarily as a third-party seller on Amazon, eBay or similar platforms, often reselling branded goods. Margin pressure is high and platform dependency is significant. Buyers will scrutinise whether there is genuine brand or operational differentiation.
How e-commerce businesses are valued
E-commerce businesses are typically valued on a multiple of adjusted EBITDA or seller discretionary earnings (SDE). The multiple reflects revenue quality, traffic diversification, platform risk, supplier security, brand strength and growth trajectory.
Revenue quality matters more than revenue size.A business generating £500,000 per year through stable organic search, a loyal repeat-customer email list and a reliable own-brand product range is worth more than a business generating the same revenue almost entirely through paid advertising with thin margins and supplier concentration.
Platform dependency is a key risk factor.Amazon FBA businesses, for example, are subject to Amazon's policies on fees, reviews, listing restrictions and account suspension. A business that has received an Amazon account warning, had an ASIN suppressed or relied on incentivised reviews is a riskier acquisition than one with a clean account history.
Traffic source diversification.Buyers will categorise traffic into owned (email, direct), earned (organic search, organic social) and rented (paid ads). Businesses where the majority of revenue depends on paid advertising are more vulnerable to cost increases, platform algorithm changes and competition. Organic traffic — particularly from well-established SEO — is more defensible.
Supplier security.A business that sources all its products from a single supplier — particularly an overseas supplier with no exclusivity agreement — faces significant supply chain risk. Buyers will assess alternative sourcing options and the consequences of the primary supplier relationship breaking down.
Stock.Finished goods stock is typically included in the sale at cost price, agreed separately from the goodwill purchase price. Buyers will verify the stock through an independent stocktake or by reviewing fulfilment centre records. Obsolete, slow-moving or customer-specific stock may be discounted or excluded.
Multiplesfor e-commerce businesses vary widely — from 2x to 5x annual SDE or EBITDA for quality businesses, with lower multiples for businesses with significant platform dependency, single-channel risk or supplier concentration. Amazon FBA businesses may trade at lower multiples than DTC brands with strong organic revenue.
Financial information to prepare
Accounts.Three years of filed accounts showing revenue, cost of goods sold, gross profit, overheads and net profit.
Management accounts.Year-to-date management accounts for the current year, with comparatives.
Platform sales reports.Export detailed sales data from each platform — Shopify, Amazon Seller Central, eBay Seller Hub, Etsy — showing revenue by product, by period and by channel. These reports are the primary evidence of trading history.
Revenue by channel.Break down revenue between the website, Amazon, eBay and any other channels. Show the trend over three years.
Gross margin by product or product category.Buyers want to understand which products generate the strongest margins and whether margins are stable, improving or under pressure.
Paid advertising spend and ROAS.For businesses that use Google Ads, Meta Ads or other paid channels — total advertising spend by period, revenue attributable to paid advertising, and return on ad spend. Separating paid revenue from organic revenue is important for assessing income quality.
Stock valuation.Current stock at cost price, by SKU or product category. Include raw materials, finished goods and packaging. Flag any slow-moving or obsolete stock.
Supplier invoices.Evidence of actual cost prices from suppliers, which buyers will use to verify the gross margin figures in the accounts.
VAT returns.To cross-check against declared revenue. Note that e-commerce businesses selling across multiple countries may have VAT obligations in multiple jurisdictions — particularly since the UK left the EU and new distance selling rules apply.
Payroll or contractor costs.Any staff, virtual assistants, freelancers or agency costs associated with running the business.
Add-back schedule.Owner's salary above market rate for a replacement operator, personal costs through the business, one-off professional fees.
Key metrics to know:
Monthly and annual revenue by channel
Gross margin percentage
EBITDA or SDE
Customer acquisition cost (CAC)
Customer lifetime value (CLV)
Repeat customer rate
Email list size and open/click rates
Paid ad ROAS
Organic traffic volume and trend
Inventory turnover
Stock days on hand
Amazon seller rating and feedback score, if applicable
Platform, traffic and marketing checks
Website and domain
The website and domain are core assets. Buyers will check:
Domain ownership.Who owns the domain? Is it registered to the business owner personally or to the company? Is it due for renewal soon? Can it be transferred cleanly?
Platform account.If the website runs on Shopify, is the account in the business name and transferable? Are all apps, themes and integrations documented?
Google Analytics.Buyers will want access to Google Analytics (or GA4) to review traffic trends, sources, conversion rates, bounce rates and revenue. Sellers should ensure tracking is correctly configured and that data covers at least the past three years.
Google Search Console.Organic search performance — impressions, clicks, rankings — is important for assessing SEO strength and identifying any manual penalties or algorithmic issues.
Conversion rate.What percentage of website visitors make a purchase? A stable or improving conversion rate suggests a well-optimised site and a resonant product range.
Amazon Seller Central
For Amazon FBA businesses, buyers will review:
Account health dashboard.Any warnings, violations, policy issues or account suspensions in the history
ASIN performance.Best-seller rank, review count and rating for key ASINs
FBA inventory.Current stock levels in Amazon fulfilment centres, aged inventory and any storage fees
Advertising data.ACoS (Advertising Cost of Sale) and PPC performance
Customer feedback score.Overall seller rating
Returns rate.Products with high return rates are a warning sign of quality issues
Paid advertising
Buyers will review ad account performance to assess how much revenue is paid versus organic, and whether paid acquisition is profitable:
Account history and performance data for Google Ads, Meta Ads and any other channels
Average ROAS by channel and by campaign type
Whether ad accounts are in the business name and transferable
Whether there have been any policy violations, account suspensions or disapproved ads
Email marketing
The email list is often the most transferable and valuable digital asset in a DTC e-commerce business. Buyers will assess:
List size — number of subscribers
List quality — open rate, click rate, unsubscribe rate
Segmentation — new customers, repeat customers, lapsed customers
Revenue generated from email campaigns
The email marketing platform — Klaviyo, Mailchimp, etc. — and whether it can be transferred
Stock, suppliers and fulfilment
Stock
Stock is typically the largest tangible asset in an e-commerce business and is usually the subject of specific negotiation in the sale.
Sellers should prepare:
A full stock schedule by SKU — quantity, cost price, selling price and stock age
Identification of slow-moving or obsolete stock (typically items with no sales in the past ninety days)
Any customer-specific or pre-sold stock
Stock held in third-party fulfilment centres or Amazon FBA — with access to inventory reports
Any stock in transit from suppliers at the time of the sale
The purchase price for stock is usually agreed separately from the goodwill price — either at cost price, or at cost price adjusted downward for slow-moving lines. A professional stocktake is recommended where stock volumes are significant.
Suppliers
Supplier relationships are critical to the ongoing operation of the business. Buyers will want to understand:
Who the key suppliers are and where they are located
Whether the business has written supply agreements or operates informally
Whether the supplier relationship is exclusive or whether the same products are available to competitors
Lead times, minimum order quantities and payment terms
Whether the supplier has been informed of the proposed sale (in most cases, sellers should not inform suppliers until the transaction is more advanced)
Alternative supplier options if the primary supplier relationship breaks down
Single-supplier dependency is a significant risk factor. Buyers will assess the consequences of losing the primary supplier and whether alternatives exist.
Fulfilment
Buyers will assess the fulfilment model and its costs:
In-house fulfilment.Orders are picked and packed at the seller's own premises. Does the buyer plan to continue this? Does it require a premises lease transfer?
Third-party logistics (3PL).Orders are fulfilled by a third-party warehouse. Is the 3PL agreement documented? Is it transferable? What are the costs and service levels?
Amazon FBA.Amazon holds and ships stock. This is straightforward to transfer — subject to the Amazon account transfer being managed correctly.
Dropship.Orders are fulfilled directly by the supplier. What are the supplier's dropship terms and costs?
Customer data, email lists and data protection
E-commerce businesses hold significant amounts of customer personal data — names, email addresses, postal addresses, purchase histories and sometimes payment card tokens. This data is subject to the UK GDPR and the Data Protection Act 2018.
Email marketing consent.The ICO's PECR rules govern electronic marketing. Email marketing to consumers requires either explicit consent or a soft opt-in (the customer bought from the business and was given a clear opportunity to opt out of future marketing). Buyers will check that the email list was built lawfully and that marketing consents are documented.
Customer data transfer.Customer data cannot simply be handed to a buyer without considering the lawfulness of that transfer. The ICO has published guidance on data sharing in mergers and acquisitions. Sellers should take data protection advice on the correct approach to transferring customer data as part of the sale.
Privacy policy.The website should have a current, accurate privacy policy explaining how customer data is collected and used.
Data retention.Does the business have a documented approach to retaining and deleting customer data? Buyers who inherit an e-commerce business with years of unmanaged customer data may face ICO obligations to cleanse it.
Data breaches.Has the business experienced any data breaches? Were they reported to the ICO as required?
Do not share the customer database with buyers until appropriate confidentiality protections are in place and the sharing is covered by appropriate legal basis.
IP, brand and product image ownership
Intellectual property is often underestimated in e-commerce sales but can be a significant issue.
Brand and trademarks.Is the brand name registered as a UK trademark? Who is the registered owner? If the brand name is not trademarked, buyers face the risk that a competitor could register it after the sale.
Product photography.Who commissioned the product photography? If a freelance photographer was used, copyright in the images may belong to the photographer unless there is a written assignment. Buyers need to know that the product images on the website and Amazon listings can be used lawfully.
Product descriptions and copy.If website copy or product descriptions were written by a freelancer or agency, copyright may need to be assigned. Buyers will want clean title to all creative content.
Product designs and formulations.For own-brand products, who owns the product design, packaging design or product formulation? Are design rights registered?
Software and code.If the website was built by an agency or developer, who owns the code? Is there a licence for ongoing use, or has copyright been assigned to the business?
Stock images and licences.Are any stock images used on the website properly licensed for commercial use?
Sellers should carry out an IP audit before going to market — identifying all creative assets, confirming ownership and obtaining any missing assignments from contractors or agencies.
Staff, systems and handover
Staff and contractors
Many e-commerce businesses are run by the owner with minimal staff — perhaps a virtual assistant, a freelance photographer, a social media manager or a bookkeeper. Buyers need to know:
Who does what in the business currently
Whether any staff or contractors are critical to daily operations
Whether employment contracts or contractor agreements are in place
Whether TUPE applies — it may where employees are engaged in the business being transferred
If the business is genuinely owner-operated with no staff, buyers will assess how much time the owner currently spends running it and what tasks the buyer will need to take on or outsource.
Systems and software
Prepare a complete list of:
E-commerce platform — Shopify, WooCommerce, etc.
Email marketing platform — Klaviyo, Mailchimp, etc.
Accounting software — Xero, QuickBooks, etc.
Inventory management software
Customer service tools — Gorgias, Zendesk, etc.
Analytics tools — Google Analytics, Triple Whale, etc.
Social media scheduling tools
Advertising platforms — Google Ads, Meta Business Manager, etc.
Password manager access
Confirm which accounts are in the business name and transferable, and which are personal accounts that will need to be recreated by the buyer.
Handover
E-commerce businesses can be transitioned more efficiently than most bricks-and-mortar businesses, but buyers still need a structured handover. A reasonable handover plan should cover:
Transfer of all platform accounts and access credentials
Introduction to key suppliers and 3PL partners
Walkthrough of fulfilment operations and day-to-day processes
Training on advertising accounts and campaigns
Transition of customer service processes
Documented standard operating procedures (SOPs) for all recurring tasks
Sellers who have documented their operations in SOPs are easier to buy from — and typically achieve better prices, because buyers have more confidence that the business will continue to run smoothly without them.
What mistakes should sellers avoid?
Conflating paid revenue with organic revenue.Buyers know the difference. Presenting all revenue as if it is equally sustainable without distinguishing paid traffic from organic is misleading and will be identified.
Not preparing platform sales reports.Accounts alone are not sufficient evidence of e-commerce trading. Buyers need platform-level data — Shopify reports, Amazon Seller Central exports — to verify revenue, margin and channel performance.
Overstating stock value.Slow-moving, obsolete or customer-specific stock is worth less than cost price. Be realistic about stock quality before entering negotiations.
Missing IP assignments.Product images, website copy and creative assets created by freelancers may not be owned by the business without written assignments. Discovering this in due diligence causes delays and price reductions.
Sharing customer data too early.The customer database is sensitive personal data. Do not share it without appropriate confidentiality protections and legal advice.
Ignoring VAT compliance.E-commerce businesses selling to customers in the UK and overseas must comply with UK VAT rules, including rules on digital services and the OSS/IOSS schemes for EU sales. Historical VAT non-compliance can create significant liability for a buyer.
Poor handover documentation.A business where all operational knowledge sits in the owner's head is harder to buy, slower to transition and worth less. Document processes before going to market.

FAQs
How is an e-commerce business valued?
E-commerce businesses are typically valued on a multiple of adjusted EBITDA or seller discretionary earnings (SDE). Multiples vary widely — from around 2x to 5x or more — depending on revenue quality, traffic diversification, platform dependency, supplier security, brand strength, margin stability and growth trajectory. Amazon FBA businesses often trade at lower multiples than owned-brand DTC businesses with strong organic revenue.
Is an Amazon FBA business harder to sell?
Not necessarily harder, but it requires specific due diligence. Buyers will review the Amazon account health, ASIN performance, review profile, FBA inventory, advertising performance and any policy issues. Account transfer must be managed carefully — Amazon does not automatically allow account transfers and the process must be handled correctly.
Does the stock price come on top of the asking price?
Usually yes. Stock is typically valued separately from goodwill, at agreed cost price. The total consideration is the goodwill price plus stock at completion. Buyers and sellers often agree to a stocktake at or around completion to establish the final stock figure.
Can I transfer my email list to the buyer?
You can, but it requires careful handling under UK GDPR and the ICO's guidance on data sharing in M&A transactions. Sellers should take data protection advice before transferring customer data and ensure that the email list was built on a lawful basis in the first place.
Does TUPE apply to e-commerce staff?
TUPE will normally apply to employees who are engaged in the business being transferred. If the business has staff or workers — even part-time — take specialist employment legal advice on TUPE obligations.
What VAT issues should e-commerce sellers be aware of?
E-commerce businesses may have VAT obligations in the UK and potentially in overseas jurisdictions. Sellers should ensure that UK VAT is correctly accounted for, that any historic under-declaration is addressed before sale, and that any overseas VAT obligations (particularly post-Brexit EU distance selling rules) are understood and complied with. Buyers will ask about VAT history and any HMRC correspondence.
Key takeaways
E-commerce businesses are valued on revenue quality, not just revenue size — organic, repeatable income is worth more than paid, platform-dependent income.
Platform sales reports — not just financial accounts — are the primary trading evidence buyers need.
Traffic source diversification matters: owned audience (email, SEO) is more durable than rented audience (paid ads).
Stock is valued separately from goodwill and requires a clear, accurate schedule.
Supplier security and single-supplier dependency are key due diligence areas.
IP ownership of brand, product photography and creative assets must be clean and documented.
Customer data transfer must comply with UK GDPR — take data protection advice.
Document your operations in SOPs before going to market — it makes the business easier to buy and supports the asking price.
