Platform Dependence: How Marketplace and Channel Concentration Affect E-Commerce Value
Many successful online businesses are built on someone else’s platform. They sell through a large online marketplace, run their store on a hosted storefront platform or rely on one advertising network for most new customers. That can be an efficient way to grow. It also means a large share of the business depends on rules, fees and decisions made by a company the owner does not control. E-commerce platform dependence is one of the most important risks buyers, sellers and lenders evaluate in an online business.
This article explains the forms platform and channel dependence takes, why it matters for value and financing, how to measure it and how owners can reduce it.
Forms of Dependence
Marketplace concentration
A business that generates most of its sales through one online marketplace depends on that marketplace’s fees, search rankings, policies and account standards. Changes in any of these can affect sales quickly, and account restrictions or suspensions can interrupt revenue.
Advertising channel concentration
Some businesses rely on one advertising platform for most new customers. Rising costs, policy changes or performance shifts on that channel can raise customer acquisition costs or reduce sales.
Storefront and infrastructure dependence
Businesses also rely on storefront platforms, payment processors, apps and fulfillment services. Disruptions or term changes can affect operations, though these are often easier to replace than a primary sales channel.
Product and supplier concentration
Dependence on one product or one supplier is a related risk. A single listing or a single manufacturer can carry much of the business.
Why Dependence Matters
Value
Buyers pay for earnings they expect to continue. Earnings concentrated in one channel are less certain, so they generally support a lower price or a structure that shares risk with the seller. Our guide to e-commerce business valuation explains how this affects price.
Financing
Lenders may discount earnings tied heavily to a single platform, ask more questions about account standing and look closely at how the business would perform if a channel changed. See our guide to e-commerce loan requirements.
Transferability
When a business changes hands, platform accounts may or may not transfer, depending on each platform’s terms and the circumstances. A business whose sales are tied to one account carries additional transition risk.
How to Measure It
- Revenue and profit by sales channel, by month, over several years
- New customers by acquisition source
- Advertising spend by channel
- Account health history, warnings and policy issues on each platform
- Revenue by product and by supplier
- The share of customers the business can contact directly with permission
Buyers should include these reports in their review, as outlined in our e-commerce due diligence checklist.
How Owners Reduce Dependence
- Build direct sales: grow sales through the business’s own website
- Diversify channels: add additional marketplaces, wholesale or retail partners where they fit the brand
- Diversify acquisition: develop organic, email and referral sources alongside paid advertising
- Own customer relationships: build permission-based customer lists
- Strengthen the brand: make customers seek the product by name
- Diversify products and suppliers: reduce reliance on any single item or manufacturer
- Maintain compliance: keep accounts in good standing and understand platform policies
Dependence in an Acquisition
Buyers who find significant concentration can negotiate a longer seller transition, structure part of the price as deferred or performance-based payments, reduce the price or decide the business is not a fit. Established operators adding a business to their portfolio sometimes view a new channel as diversification; see our guide to add-on acquisitions for established e-commerce operators.
Dependence When Selling
Owners planning to sell can improve value and financeability by reducing dependence before going to market. See our guide on how to sell an e-commerce business.
Diversification Builds Durability
Relying on a large platform is often how online businesses get started, and it is not automatically a problem. But the more a business depends on any single channel, the more its value and financing depend on that channel’s decisions. Owners who measure and manage that dependence build businesses that are worth more and easier to finance.
