Increase & Protect Ecommerce Profit Margins Across Marketplaces

Ecommerce isn't slowing down. Global ecommerce sales are projected to hit $7.41 trillion in 2026 (an 8% increase from 2025) and are expected to continue growing at a CAGR of 7.8%, surpassing $8 trillion by 2027. That kind of sustained momentum represents an enormous opportunity for brands. But opportunity and profitability aren't the same thing, and for many brands expanding across multiple marketplaces, the gap between the two is widening.  

As more brands diversify beyond a single channel, the complexity of running a profitable operation multiplies. Each marketplace comes with its own fee structures, advertising platforms, fulfillment requirements, and competitive dynamics. Without a deliberate strategy, the very expansion meant to drive growth can quietly erode the margins that make growth sustainable.

That's why protecting and growing profit margins across marketplaces isn't just a financial exercise — it's a strategic imperative. In this article, we'll break down the key levers brands can pull to both defend their margins from common threats and actively improve them, no matter how many channels they sell on.

Increase and Protect Profit Margins

Streamline Operations to Unlock Hidden Margin

Efficiency is the foundation of profitability. Before margins can grow, brands need to identify where revenue is quietly leaking. And, for most brands operating across multiple marketplaces, operational inefficiency is one of the biggest culprits. While gross margins for ecommerce businesses average around 45%, the average net margin drops to approximately 10% after accounting for marketing, fulfillment, and operational expenses. That gap represents a significant opportunity for brands willing to take a hard look at how their operations are structured.  

The more marketplaces a brand sells on, the more complex its operations become. Inventory management, order routing, fulfillment timelines, and channel-specific compliance requirements all multiply with each new channel added. Without systems in place to manage that complexity, costs scale faster than revenue — and margins shrink as a result.

The good news? Technology has made operational efficiency more accessible than ever. Warehouse automation adoption is on track to hit 75% by 2027, with AI and robotics already transforming fulfillment efficiency by up to 65%.

• Centralize inventory management: Use a single inventory management system that syncs across all your marketplace channels in real time. This eliminates costly overselling, stockouts, and the manual reconciliation that creates errors and wastes resources.
• Evaluate your fulfillment strategy: Local and proximity-based fulfillment operations deliver cost savings and accuracy compared to traditional centralized distribution. If your current fulfillment setup isn't optimized for where your customers are, you're spending more than necessary on every single order.  
• Leverage 3PL partnerships: For brands not ready to build out their own distribution infrastructure, partnering with a 3PL with established marketplace relationships can dramatically reduce fulfillment overhead while maintaining service quality and speed.
• Audit your returns process: In 2024, U.S. ecommerce returns totaled $890 billion, costing retailers between 20–65% of an item's original value. Investing in better product descriptions, sizing guides, and packaging quality reduces return rates and recovers meaningful margin on every order that doesn't come back.

Increase Average Order Value (AOV) to Grow Revenue

Growing revenue doesn't always mean acquiring more customers. One of the highest-leverage moves a brand can make is increasing how much each existing customer spends per transaction. As of November 2024, the global average order value in ecommerce reached $144.57. Brands that actively manage and optimize their AOV are capturing more of that upward trend than those that leave it to chance.

The margin math behind AOV is compelling. More revenue from the same customer acquisition cost means every incremental dollar of spend per order flows through at a dramatically higher margin than revenue earned from a net-new customer. Cross-selling alone accounts for 10–30% of total ecommerce revenues, according to Forrester Research, and it remains one of the most under-leveraged tools in the average brand's playbook.

• Bundle strategically: Product bundles increase AOV, with some brands achieving profit increases of up to 30%. Build bundles that solve a real problem or complete a use case for your customer — not just groupings of products that happen to share a category.
• Set free shipping thresholds: A majority of shoppers will add extra items to their cart in order to reach a free shipping threshold. Setting that threshold just above your current AOV nudges larger baskets while keeping the economics working in your favor.
• Use post-purchase upsells: Offering a discount on a complementary item immediately after checkout is one of the least intrusive and most effective moments to increase spend.
• Personalize product recommendations: Generic "frequently bought together" widgets provide modest gains, but behavioral personalization tailored to purchase history and customer segment signals drives significantly higher results. According to McKinsey, companies that master hyper-personalization generate 40% more revenue from those activities than their competitors.

Cut Down Costs Across the Supply Chain

Increasing revenue is only half of the equation. The other half is keeping more of it. For brands managing multiple marketplace channels, cost creep is a constant threat — advertising fees, fulfillment costs, platform commissions, and vendor inefficiencies can quietly compound until margins stall. Industry standards now suggest that total operating expenses should remain under 30% of revenue to maintain profitability.

Winning on cost doesn't mean cutting corners. It means making smarter decisions about where dollars are going and what return they're generating. Small, intentional reductions across several cost categories add up to meaningful margin improvement at scale.

• Renegotiate supplier terms: Many brands set supplier agreements once and rarely revisit them. As order volumes grow with marketplace expansion, there's real leverage to negotiate better unit costs, payment terms, and minimum order quantities. Even a 2–3% reduction in COGS compounds significantly at scale.
• Optimize ad spend with incrementality: Amazon advertising alone can consume gross sales. Moving beyond surface-level ROAS metrics to evaluate which spend is actually driving incremental revenue, versus what would have converted regardless, is one of the fastest ways to recover meaningful margin.

• Right-size your packaging: Dimensional weight pricing applies across every major carrier and marketplace. Oversized packaging isn't just wasteful, it's expensive on every single shipment. A systematic audit of packaging specs relative to product dimensions frequently uncovers significant, recurring savings.
• Consolidate vendors and platforms: The overhead of managing a fragmented tech stack or vendor list adds up fast. Consolidating around fewer, more capable partners reduces both direct costs and the internal time spent managing those relationships, freeing up resources to focus on growth.

Improve Customer Retention to Drive Profit

Retention is one of the most powerful margin levers in ecommerce, yet most brands continue to over-index on acquisition. Customer acquisition costs have surged 222% over the last five years, and the average ecommerce store loses 70–77% of its customers every year. That's an expensive cycle to keep funding.  

The financial case for investing in retention is hard to argue with. A 5% increase in customer retention can boost profits by 25–95%, while acquiring a new customer costs 5–25 times more than keeping an existing one. The revenue quality is different too — the quarter of conversions that come from returning customers generates 43% of brand revenue and 100% of the profit.  

• Build a post-purchase experience: The window immediately following a purchase is one of the highest-leverage moments to establish loyalty. Proactive order tracking, a smooth unboxing experience, and thoughtful follow-up communication all signal to customers that your brand is worth returning to.
• Make returns easy: Most consumers say they will make repeat purchases if the returns process is easy. A frictionless return policy converts a potential frustration into a loyalty-building moment.
• Launch or optimize a loyalty program: Well-designed loyalty programs drive higher purchase frequency, larger basket sizes, and stronger brand advocacy — all without requiring additional acquisition spend. The compounding effect on margins over time is substantial.
• Use email and SMS: Email is a key driver of retention program engagement and is identified by many small and mid-size businesses as their most important retention tool. Automated flows (including cart abandonment sequences, back-in-stock alerts, and win-back campaigns) keep your brand front of mind in the moments most likely to drive a repeat purchase.

Adjust Your Pricing Strategy to Compete and Protect

Pricing is one of the most direct levers brands have to influence profitability, yet many brands treat it as a one-time decision rather than an ongoing strategy. In a multi-marketplace environment where competitors can reprice in real time, a static pricing approach leaves money on the table.

According to McKinsey, companies that implement dynamic pricing strategies can see margin improvements of 5–10% and sales growth of 2–5%. Those aren't massive numbers in isolation but applied consistently across a growing product catalog and multiple channels, they add up significantly.

• Implement channel-specific pricing: Not every marketplace has the same cost structure, customer intent, or competitive dynamic. Pricing uniformly across all channels ignores those differences. Where platform rules allow, tailor your pricing to reflect the true cost of selling on each channel and the margin you need to sustain it.
• Set and enforce MAP policies: Unauthorized resellers underpricing your products erode brand equity and make it harder to maintain healthy margins across all channels. A clearly communicated and actively enforced MAP policy is a foundational element of any multi-marketplace pricing strategy.
• Use dynamic pricing tools: Automated repricing can help you stay competitive around the clock, but without margin floors in place, it can also reprice you into unprofitability. Set minimum price thresholds that preserve your target margin before deploying any automated repricing tool.  
• Price on value, not just cost: Value-based pricing focuses on the benefits and perceived value a customer receives rather than just your cost or a competitor's price point. Brands that invest in strong product content, reviews, and brand presentation can often command a premium. Competing solely on price is a race to the bottom that no brand wins.

Maximize Margins on the Right Marketplaces

The real opportunity lies in building a deliberate strategy across all three major marketplaces – Amazon, Walmart, and Target. Relying on a single platform exposes brands to significant risks, including fluctuating fees, policy changes, and increased competition — all of which reduce control over profit margins. A diversified multi-channel presence reduces that exposure while simultaneously expanding the total addressable audience. Each marketplace unlocks a customer segment that the others don't fully capture, and each offers a cost structure that can be more favorable for different parts of a brand's catalog.

The brands that are growing margins most effectively treat each channel as its own P&L, assign products to the channels where their economics work best, and invest in the operational infrastructure needed to manage all three without letting complexity erode the margin gains they've worked to build.

Amazon

• Run regular fee audits: Amazon's fee structure evolves every year. Build a cadence of quarterly fee reviews to identify where costs have shifted and where pricing or fulfillment adjustments are needed to maintain your target margin.
• Optimize product sizing and packaging: FBA fees are driven by the size and weight of each unit. Reducing dimensional weight through smarter packaging design can yield meaningful per-unit savings across large order volumes.
• FBA vs. FBM: With FBM, you only pay the referral fee and take on fulfillment yourself, which can be significantly more profitable for certain product types, particularly larger or heavier items where FBA fees are disproportionately high.
• Audit advertising spend: Amazon advertising can consume 20–33% of gross sales for some sellers. Cutting spend that isn't driving truly incremental revenue is one of the fastest paths to improved margins on the platform.

‍

Walmart

• Prioritize Walmart categories: The combination of lower referral fees and less competition makes Walmart particularly attractive for product categories that carry high FBA costs or face aggressive pricing pressure on Amazon.
• Leverage Walmart Fulfillment Services: Listings fulfilled through WFS earn the "2-Day Delivery" badge, which drives significantly higher conversion rates. More sales at the same cost means improved effective margin per listing.
• New seller incentives: Walmart has offered new sellers up to 25% off fulfillment fees and 50% off storage fees for new accounts. These programs change periodically, so check Seller Center regularly and factor available incentives into your launch economics.
• Invest in content quality: With a smaller, less competitive seller pool, well-optimized listings stand out more on Walmart than they would on Amazon. Brands that invest in strong titles, imagery, and enhanced content capture a disproportionate share of Walmart's growing organic traffic.

‍

Target

• Position your brand proactively: Target Plus is invite-only, which means brands need to build the kind of marketplace presence and reputation that puts them on Target's radar. Strong Amazon and Walmart performance, excellent reviews, and fast, reliable fulfillment all support a compelling case.
• Price at full value: The curated, less competitive environment on Target Plus supports stronger pricing. Brands that sell at a race-to-the-bottom price point on Amazon can hold firmer on Target Plus. That pricing difference flows directly into improved margins.
• Leverage Target Circle: Target's Circle loyalty program has more than 100 million members. Brands that actively integrate with Target Circle promotions gain access to that loyal audience at a fraction of the customer acquisition cost they'd spend on other channels.  
• Use Target Plus for brand equity: The association with Target's brand elevates perception in ways that translate to pricing power everywhere else you sell. Brands on Target Plus consistently report stronger conversion rates and reduced reliance on price-based promotional tactics across their entire channel mix.

Increasing ecommerce profit margins across multiple marketplaces doesn't happen by accident. It's the result of deliberate decisions made consistently. The opportunity is real and growing. But so is the complexity. As marketplaces continue to evolve, the brands that thrive will be the ones with a clear strategy and the right partners in place to execute it. Whether you're just beginning to expand beyond a single channel or you're already selling across multiple marketplaces and looking to sharpen your profitability, the path forward starts with an honest look at where margin is being left on the table — and a plan to go after it.
