Why unified commerce is replacing traditional e-commerce operations
Buying now often starts before a shopper goes looking for a retailer, since a short video can put the product and the buy button on the same screen. AP reported in 2023 that TikTok Shop brought that behavior into the U.S. mainstream with a Shop Tab and affiliate videos, turning social content into a path toward checkout.
The same article cited Insider Intelligence’s estimate that social commerce had grown into a $69 billion U.S. market at the time, showing how much shopping activity had already moved onto social feeds. But the harder work starts after the tap, since the order still has to match real inventory and customer records.
Shopify’s enterprise commerce analysis explains that disconnected commerce systems add coordination work each time a business adds another project. And fulfillment operators see that strain around orders and inventory as brands try to keep newer buying habits from breaking older e-commerce operations.
With each added channel, retailers are moving toward unified commerce to keep the order tied to the same inventory record after the shopper leaves the screen. AMS Fulfillment examines the rise of unified commerce in e-commerce operations.
From Omnichannel to Unified Commerce
Selling through many channels is now standard for brands, from websites to store shelves. Retail analysts call that setup omnichannel, where the same brand appears in each place but often runs on separate software.
Josh Sevcik, lead commerce strategist at CDW, told BizTech Magazine in 2025 that omnichannel was “really about connecting all of the dots,” while unified commerce creates “that continuous, uninterrupted experience.”
Separate systems may refresh only after a delay, so a product can sell out in-store while the website still lists it, or a sale can start online while the register still charges full price. Unified commerce reduces those errors by keeping every selling path tied to the same record.
Bain and Aptos surveyed more than 300 retail executives for its 2023 State of Unified Commerce report. Nearly all tied a well-run unified commerce strategy to stronger profitability and sales. One chief operating officer surveyed described “unified commerce” as “one unified view of the inventory,” letting a brand sell the same stock from any channel.
Why Consumers Expect One Seamless Experience
Shoppers now treat each buying step as part of the same retailer, even when the work behind it moves through different teams. So a price checked on a phone should match the store shelf, and an order placed online should show the same status when customer service looks it up.
More than half of B2C customers use three to five channels during a purchase or service request, according to McKinsey research from 2022, and those cross-channel shoppers shop 1.7 times more often than single-channel shoppers.
And more frequent buying gives the customer experience a larger role in repeat sales. Salesforce Research found that 80% of customers consider a company’s experience as important as its products and services.
Retailers hear the same standard inside their own companies. In Bain’s State of Unified Commerce report, a chief operating officer said customers “just expect” a unified retail and online experience. If a retailer falls short of that standard, an inconsistent price or missing order update makes the company appear to have lost track of the sale.
Inventory Visibility Is the Foundation
Retail researchers are now tying store choice to a simple question shoppers ask before they buy: whether the product is actually available.
Recent McKinsey and ICSC research found that 37% of surveyed consumers ranked in-stock reliability among their top three reasons for choosing a retailer. The same concern shows up most clearly in pickup and delivery, since a shopper often trusts the stock count on screen before leaving home.
Retailers are investing to mitigate that risk as well. The Bain and Aptos research found that about 80% have already invested in real-time inventory management and visibility. And that investment starts with a live count, giving teams a current answer before an order is assigned, while an old count can keep selling stock already gone.
But the problem can run the other way too, with sellable stock sitting unseen at another location. Better visibility closes that blind spot by giving teams the current information they need to send the order to the right place the first time.
The Fulfillment Network Has Become More Complex
Retail’s physical side has become a puzzle with more pieces: An individual order is a decision that can follow several possible paths. Bain and Aptos research notes that buying online and picking up at a store requires both a shared view of stock and a flexible way to fill the order.
Older e-commerce ran more simply, with a brand keeping stock in one warehouse and shipping website orders from one place. But sales now come from a brand site and an online marketplace, while wholesale accounts draw from the same goods.
Operators who run this work see the squeeze daily, since a website shopper may want one item shipped today while a retail partner needs a full pallet on a set date. And sending that pallet out can empty the inventory that the website relies on. Keeping every path supplied now takes more planning than it did when goods left one door.
Unified Data Leads to Better Business Decisions
Connected data now sits behind the business calls retailers make every day, from what to reorder to which products need a price change. Disconnected data leaves retailers working with inaccurate inventory and lost sales.
But inside daily retail work, one inaccurate number can send a merchant toward the wrong order or the wrong markdown. IHL Group described the same risk in blunt terms, saying “bad data just gets you faster bad results.” Better decisions start when shopper behavior and sales activity are viewed together, rather than split by channel.
Even Bain and Aptos research connects that fuller view to better retail decisions, noting that retailers are more likely to succeed when they use data analytics to understand shopper behavior across physical and digital channels.
With that information in one place, a merchant can see where demand is building before buying more stock or cutting prices. It also keeps one channel’s numbers from steering a decision that affects the whole business.
Technology Is Making Unified Commerce Possible
Retail technology now has a more practical job, giving the systems behind a sale the same numbers before teams make the next move. That job now sits near the center of unified commerce, with retailers naming inventory management and order-management tools among the most important technologies supporting it, according to the Bain and Aptos research.
A warehouse system handles the physical side of that work by showing the location of goods, while an order system uses the same information to determine where a purchase should move.
Cloud commerce platforms keep the shared information usable beyond the warehouse, holding product records and prices ready for the teams selling the item. And APIs carry those numbers between systems built separately, so a sale on one screen does not leave another team working from an old count.
According to Gartner research, 91% of retail IT leaders have prioritized AI as the top technology to implement in 2026. AI depends on that connected base before it helps adjust pricing or guide store associates during a sale.
Together, the tools turn unified commerce into daily work that a retailer can actually run, with fewer handoffs left to people copying numbers from one screen to another.
Why Unified Commerce Is Becoming the New Retail Standard
Change has always been part of retail, but the pressure now comes from how quickly buying habits move across channels. Operators who handle omnichannel fulfillment note that shoppers rarely stick to a single channel now, so serving people across all of them has become the everyday job.
Older e-commerce setups have less room to hold up under that job, since separate systems slow the work behind each order.
Unified commerce answers by running every channel as one operation. It treats omnichannel selling and unified operations as two halves of one promise, with fulfillment built to support how people already shop.
