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 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 report cited Insider Intelligence’s estimate that social commerce had grown into a $69 billion U.S. market, 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 such as AMS Fulfillment see that strain around orders and inventory as brands try to keep newer buying habits from breaking older eCommerce 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.
From Omnichannel to Unified Commerce
Selling through many places is now standard for brands, from a website to a store shelf. 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 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 at the 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 about that shared system, and nearly all tied a well-run version to stronger profitability and sales. A chief operating officer among those surveyed described it 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 carry the same status when customer service looks it up.
McKinsey research says more than half of B2C customers use three to five channels during a purchase or service request, and those cross-channel shoppers shop 1.7 times more often than single-channel shoppers.
And more frequent buying gives the experience a larger role in repeat sales, as Salesforce Research found 80% of customers rate a company’s experience as highly as its products and services.
Retailers hear the same standard inside their own companies, including a chief operating officer surveyed by Bain and Aptos, who said customers “just expect” a unified retail and online experience. If a retailer falls short of that standard, a mixed price or missing order update makes the company look like it 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.
McKinsey and ICSC research found 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 is often trusting the stock count on screen before leaving home.
Retailers are investing around that risk as well, with Bain and Aptos research finding about 80% have already put money into 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, and fulfillment experts now describe a single order as a decision with several possible paths. Bain and Aptos research puts that pressure in practical terms, noting that buy online and pickup at a store requires both a shared view of stock and a flexible way to fill the order.
Older eCommerce 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 shelf the website was still selling from. So 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. Michael Scheibner wrote in Forbes that disconnected data leaves retailers working with inaccurate inventory and lost sales.
But inside daily retail work, one weak 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 stronger retail decisions, noting that stronger retailers 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. Bain and Aptos research shows why 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.
A warehouse system handles the physical side of that work by showing where goods sit, while an order system uses the same information to decide 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.
Michael Scheibner wrote in Forbes that 91% of retail IT leaders have prioritized AI as the top technology to implement in 2026, citing Gartner research. 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 a retailer can actually run, with fewer handoffs left to people copying numbers from one screen to another.
Conclusion: 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 hardly any shopper sticks to a single channel now, so serving people across all of them has become the everyday job.
Older eCommerce setups have less room to hold up under that job, since separate systems slow the work behind each order. Bain and Aptos research shows retailers treating the problem as an operating one, with leaders tying unified commerce to stronger sales and profitability.
Unified commerce answers by running every channel as one operation, holding the strain back before it ever touches the shopper. And the brands best positioned for what comes next treat omnichannel selling and unified operations as two halves of one promise, with fulfillment built to support how people already shop.
