Omnichannel Profitability: Why Digital Growth Must Be Managed Through Cost-to-Serve Discipline
Retail and wholesale leaders are operating in a market where digital demand continues to grow faster than overall sales, but the economics are becoming harder to manage. The U.S. Census Bureau reported that first-quarter 2026 U.S. retail e-commerce sales reached $326.7 billion on a seasonally adjusted basis, up 9.8% from the first quarter of 2025, while total retail sales rose 3.9% over the same period. E-commerce represented 16.9% of total retail sales.
The top-line signal is attractive. But the operating reality is more complicated. Digital growth brings more fragmented inventory, more fulfillment nodes, more returns, more customer-service touchpoints, more last-mile variability, and more pressure on store and warehouse labor. For many retailers and wholesalers, the question is no longer whether digital demand will continue to grow. It is whether that growth can be served profitably.
Digital growth is not the same as profitable growth; every customer promise must be matched by the operating model required to serve it.
The Growth Is Real, but the Cost Is Often Hidden
Retail sales remain resilient. The National Retail Federation forecasts 2026 retail sales growth of 4.4% over 2025 to $5.6 trillion, above the 3.6% average annual growth rate over the prior decade when pandemic years are excluded. That creates a strong growth backdrop, but it also raises the bar for execution. In an environment where consumers expect price transparency, flexible fulfillment, fast delivery, easy returns, and consistent availability, sales growth can conceal weakening unit economics.
Omnichannel complexity shows up in places that are not always visible at the merchandising or revenue level. A buy-online-pick-up-in-store order may protect a sale, but it also uses store labor, backroom space, inventory accuracy, and customer-service capacity. A ship-from-store order may improve delivery speed, but it can disrupt store execution and raise labor cost. A digital order fulfilled from a distant distribution center may look like e-commerce growth, but freight, split shipments, substitutions, packaging, and returns can consume the margin.
Retail and wholesale leaders need to move beyond channel-level revenue reporting. They need a fact-based view of cost-to-serve by channel, customer segment, order profile, return behavior, fulfillment path, and product category. Without that view, the organization can scale the least profitable parts of the model while believing it is building digital strength.
This is especially important as the distinction between retail and wholesale service models narrows. Retailers are serving local, digital, and marketplace demand through the same inventory base. Wholesalers are serving customers through branches, field sales, inside sales, portals, EDI, and increasingly self-service digital channels. In both cases, the management problem is the same: the company must understand how each promise changes labor, inventory, transportation, working capital, and margin.
Returns Have Become an Operating-System Issue
Returns are one of the clearest examples of how digital growth can create margin leakage. The National Retail Federation and Happy Returns projected total U.S. retail returns would reach $849.9 billion in 2025, with 19.3% of online sales expected to be returned. The same research found that 82% of consumers say free returns are important when shopping online, while 9% of all returns are fraudulent.
Those numbers matter because returns touch almost every part of the operating model. They consume transportation capacity, store labor, DC labor, inventory working capital, customer-service time, inspection capacity, refurbishment capability, markdown planning, and fraud controls. They also create tension between customer experience and margin protection. A frictionless return policy can drive conversion, but it can also train costly behavior if not managed through customer profitability, product economics, and operating discipline.
The leaders in this environment will not simply make returns easier or harder. They will make them smarter. They will segment return policies, route returns intelligently, recover inventory faster, improve product content and fit information, reduce preventable returns, and make reverse logistics a managed performance system rather than a reactive cost center.
Stores and Distribution Centers Are Becoming Shared Operating Assets
The traditional separation between stores, distribution centers, e-commerce fulfillment, and wholesale service models is breaking down. Stores increasingly act as selling environments, fulfillment nodes, return centers, service points, and local inventory buffers. Distribution centers increasingly support wholesale replenishment, direct-to-consumer orders, marketplace flows, and vendor-managed inventory requirements. Wholesalers are facing similar complexity as customers expect digital ordering, fast availability checks, customer-specific pricing, and reliable delivery windows.
This makes operating coordination much more important. Inventory accuracy, labor planning, replenishment cadence, task prioritization, product data quality, order routing, and exception management all determine whether omnichannel execution creates value or cost. Technology can help, but only if the underlying process is disciplined. A modern order management system cannot protect margin if inventory records are wrong, if stores do not execute picks accurately, or if distribution labor is planned against outdated demand patterns.
The practical CEO issue is that omnichannel is no longer a digital function. It is an enterprise operating model. Merchandising, supply chain, store operations, wholesale sales, finance, pricing, technology, and customer service must manage to the same performance reality.
That requires a different cadence than many organizations use today. Weekly sales reviews are not enough if margin is being consumed daily through substitutions, exceptions, unplanned labor, freight upgrades, return backlogs, and inaccurate inventory. Leadership needs forward-looking indicators that show where service promises and operating capacity are starting to separate.
The Brooks International Perspective
From Brooks International’s perspective, omnichannel profitability is an execution discipline before it is a technology strategy. Retailers and wholesalers do not create value by adding channels; they create value by ensuring those channels are served at the right cost, with the right inventory, the right labor model, the right service promise, and the right management routines.
The opportunity is to make cost-to-serve visible and controllable. That means understanding how orders flow, where labor is consumed, where inventory is duplicated, where returns are eroding margin, where fulfillment promises exceed operating capability, and where management teams lack the daily visibility to intervene. Brooks International’s lens is not simply to reduce cost. It is to align customer promises with operational capability so growth converts into margin and cash generation.
The highest-value improvements often sit inside the existing business: improving inventory accuracy, reducing split shipments, increasing pick productivity, shortening return-to-stock cycle time, improving vendor compliance, refining labor standards, controlling promotions that trigger unprofitable fulfillment patterns, and building management routines that connect revenue, margin, service, and working capital.
The goal is not to slow omnichannel growth. It is to make growth more controllable. When leaders can see where cost is created and where value is captured, they can redesign service levels, adjust labor models, standardize fulfillment logic, and make commercial decisions that protect the customer experience without giving away profitability.
What Retail & Wholesale Leaders Should Be Asking Now
The immediate leadership agenda should focus on whether growth, digital investment, customer experience, and operational capability are being managed as one performance system:
- Which channels, fulfillment paths, customer segments, and order profiles are creating profitable growth – and which are creating hidden cost?
- Does the organization understand true cost-to-serve across stores, e-commerce, wholesale, marketplace, direct delivery, and returns?
- Are store labor, warehouse labor, and transportation plans aligned to actual omnichannel demand patterns?
- Where are split shipments, inventory inaccuracy, substitutions, and return handling eroding margin?
- Are customer promises being set by commercial ambition or by confirmed operating capability?
- Does leadership have leading indicators that show margin leakage before it appears in period-end financial results?
These questions matter because retail and wholesale performance is no longer determined by channel growth alone. It is determined by the organization’s ability to execute profitably across every channel, customer promise, and operating constraint.
The Leadership Imperative
The next stage of omnichannel growth will not reward retailers and wholesalers that simply sell through more channels. It will reward companies that know how to serve each channel profitably.
For CEOs and boards, the mandate is clear: move beyond digital growth as a standalone metric and manage omnichannel performance as a cost-to-serve system. The winners will be those that connect customer experience to fulfillment economics, inventory discipline, labor productivity, return controls, and working capital performance.
Digital growth is still a major opportunity. But without operational discipline, it can become a margin drain. Retail and wholesale leaders need an operating model built not only to capture demand, but to serve it profitably, repeatedly, and at scale.
