In the fourth quarter of 2025, U.S. retail e-commerce sales reached an estimated $316.1 billion and represented 16.6 percent of total retail sales. Online commerce is large enough to shape nearly every product strategy, but it remains one part of a broader retail and distribution environment.

Retail produces usable signals

A retail transaction contains information: the words a customer searched, the page they viewed, the price they accepted, the question they asked, the reason they returned an item, and whether they purchased again. No single signal makes a decision, but together they produce a more grounded view of demand.

That evidence helps a commerce company decide which products deserve deeper supplier work, inventory, improved content, a focused storefront, or a business-sales effort.

Marketplaces are useful—but they are not the company

Amazon, Walmart Marketplace, and eBay can provide large audiences and mature transaction infrastructure. Shopify and owned storefronts can provide greater control over presentation, customer relationships, and specialized discovery.

Concentrating all activity in one outside marketplace also concentrates fee, policy, account, advertising, and customer-access risk. A disciplined multi-channel approach does not mean listing everything everywhere. It means selecting channels according to customer behavior and full economics.

The channel reaches the customer. The company decides what to sell, how to support it, and what to learn next.

Retail learning strengthens B2B

Business buyers ask different questions than individual shoppers: volume, consistency, lead time, specifications, documentation, packaging, support, and commercial terms. Retail demand does not answer every B2B question, but it provides evidence that can make those conversations more concrete.

For Mayomark, retail is the first engine; B2B is a complementary path that can deepen supplier relationships, create larger orders, and serve buyers whose needs are not met by ordinary product pages.
