Ecommerce can help a business reach customers beyond its local area, but it does not guarantee demand, lower total costs, or profit. Selling online makes the most sense when the potential audience, fulfillment operation, customer service, security, and target-market requirements fit the business.
What counts as ecommerce?
In U.S. Census Bureau retail statistics, an ecommerce sale is counted when a customer places an order or negotiates price and terms through an internet, mobile, email, electronic data interchange (EDI), or comparable online system. The payment itself does not have to happen online. The Census definition covers specified retail businesses, not every online service.

For a business, ecommerce can also include the online advertising and brand-building that support sales, not only the website checkout. International Trade Administration: eCommerce

What are the advantages of ecommerce?
Reach customers beyond a local storefront
An online channel can make a business visible to customers elsewhere in its country and, with additional planning, to buyers abroad. The U.S. Commercial Service offers guidance to businesses exploring overseas markets. International reach still requires decisions about delivery, customer support, and the requirements of each destination market; a website alone does not make every market accessible.

Give customers more ways to discover and compare products
Online marketplaces let third-party sellers offer products through a platform, and online listings can make competing offers easier to compare. The effect depends on the product and channel: visibility and comparison may help shoppers, but neither guarantees a sale or the lowest price.
Connect selling with marketing
An online storefront, marketplace listing, advertising, and brand presence can work together to present an offer and reach an intended audience. This creates more ways to communicate with customers, while making customer acquisition an ongoing part of the operation.
Enable direct-to-customer sales and more choice
The European Commission’s 2017 ecommerce sector inquiry found that online price transparency and competition had significantly affected company distribution strategies and consumer behavior. It also documented manufacturers selling directly to consumers through online shops. These are findings about the EU market during the inquiry period, not a promise that online prices are lower in every category today. European Commission: Sector inquiry into e-commerce

What are the disadvantages and risks of selling online?
Online sales still require money and operational work
A digital channel may reduce some barriers to reaching customers, but the seller still has to provide the goods or service promised. Fulfillment, customer service, marketing, and day-to-day operations all require resources. Former FTC Commissioner Thomas B. Leary made a related observation about online commerce in a 2000 speech; it is historical commentary, not a current cost survey. There is no single startup-cost or profitability figure that applies to every business. FTC: “The Two Faces of Electronic Commerce”
Trust can be harder to establish
Customers may not be able to inspect an item or meet the seller before buying. Leary’s 2000 speech described the internet as accessible but potentially anonymous, raising concerns about knowing who is on the other side of a transaction and whether goods will arrive as promised. For a seller, clear identity and contact details, accurate listings, responsive service, and reliable delivery are practical ways to address that uncertainty. The speech is a historical policy observation, not a measure of how common online fraud is today.
Customer data creates privacy responsibilities
Online activity can help a seller understand demand, but collecting and using customer information also raises questions about what is gathered, how it is used, and how it is protected. Leary discussed this tension in 2000; his remarks should not be treated as a current account of privacy law. Applicable requirements depend on the seller and the markets it serves, so check current rules with the relevant authorities.
Cybersecurity is an ongoing responsibility
The FTC warns that cybercriminals target companies of all sizes. Its small-business guidance points to the voluntary, flexible NIST Cybersecurity Framework 2.0, which organizes risk management around six functions: Govern, Identify, Protect, Detect, Respond, and Recover. FTC: Cybersecurity for Small Business
That framework is not a one-time fix. A business should consider how it protects data, makes backups, trains staff to recognize threats, detects incidents, and plans to respond and recover. No single tool eliminates security risk.
Marketplaces do not guarantee product safety or control
A marketplace can provide a place to list products, but customers may still encounter unsafe or non-compliant goods. A UK government report published on 24 March 2025 identifies concerns about unsafe products sold through online marketplaces; it does not establish that all marketplace goods are unsafe. Office for Product Safety and Standards: Online marketplaces consumer journeys
There can also be limits on how and where goods are sold. The European Commission’s inquiry, based on evidence gathered from 2015 to 2017 and findings adopted in 2017, documented direct manufacturer sales, selective distribution, and contractual restrictions that could include marketplace bans or limits on price-comparison tools. The Commission noted that some practices may improve distribution quality, while others may unduly restrict consumer choice and lower prices. These historical EU findings are not a statement of current rules everywhere. European Commission: Sector inquiry into e-commerce
Cross-border reach brings market-specific questions
Former FTC Commissioner Thomas B. Leary wrote in 2000: “The e-commerce medium knows no national boundaries.” He immediately qualified that opportunity by noting the difficult questions about which rules apply and where disputes should be resolved. Cross-border selling therefore calls for checking current requirements in the seller’s location and each target market; the speech is historical context, not legal advice or a current regulatory position.
Environmental and compliance concerns vary by transaction
A European Commission communication dated 5 February 2025 highlights risks associated with the surge of goods imported directly to EU consumers, including non-compliant products, potential consumer health and safety harms, environmental damage, and effects on law-abiding businesses. This is EU policy context; it does not mean every ecommerce transaction has the same environmental footprint or compliance profile.

In a report published on 24 March 2025, the UK’s Office for Product Safety and Standards cited the Office for National Statistics figure that online sales accounted for nearly 30% of all UK retail sales in 2023; the report also said the share had tripled over the preceding ten years. This is a UK figure for 2023, not a global estimate or a 2026 market share. Office for Product Safety and Standards: Online marketplaces consumer journeys
How should a small business decide whether ecommerce is worth it?
Compare the online channel with the way your customers buy now. Separate setup decisions from recurring work: a shop can be launched, but attracting customers, fulfilling orders, providing service, and protecting systems continue after launch.
- Audience: Can you reach customers online who are not already served by your current channel, and is there a reason they would choose your offer?
- Fulfillment and service: Can you deliver reliably and handle questions, returns, or other service needs at the scale you expect?
- Product experience: Does the product depend on in-person inspection, fitting, demonstration, or advice that is harder to provide online?
- Security and data: Can you manage customer and business information, prepare staff, maintain backups, and plan for an incident?
- Channel control: Would a marketplace’s audience and infrastructure help, or do its competition and contractual restrictions conflict with how you want to sell? An owned storefront offers a different balance of control and customer discovery; neither option is automatically better.
- Markets and compliance: Which places will you serve, and have you checked the applicable product, consumer, privacy, tax, and other requirements for those markets?
- Customer acquisition: What ongoing effort will it take to make the offer visible to the intended audience?
The evidence does not support a universal verdict or a single comparable estimate for ecommerce startup costs or profitability relative to physical retail. The useful answer depends on your customers, channel, operations, security practices, and chosen markets.
