Measured signals
The numbers—and who was counted
17.1%
US ecommerce share
Seasonally adjusted share of US retail sales transacted through ecommerce in Q2 2026, according to the Census Bureau.
$340.2B
Quarterly sales
US ecommerce sales in Q2 2026, up 12.2% from Q2 2025—a growing channel in which assisted discovery can materially affect performance.

Rufus sales impact
Incremental annualized sales Amazon attributed to Rufus in 2025, showing the potential scale of conversational shopping.
Product truth comes first
Catalog attributes, claims, price, inventory, availability, delivery promises, and policy content must be current before conversational discovery can be dependable.
Measure retained contribution
Conversion is incomplete. Reconcile cancellations, returns, discounts, fulfillment, service, credits, fraud, and operating cost.
Authority changes the control
Describing a product, recommending one, preparing a cart, setting an offer, and completing a purchase require different evidence and recovery.
A customer needs recourse
Automated answers and actions need an understandable correction path, responsible owner, durable receipt, and practical reversal.
The measurement opportunity
Connect customer help to retained commercial value
Reach, engagement, conversion, retained orders, and contribution margin reveal different parts of the customer journey. The report shows how to connect them with a holdout or phased rollout so leaders can see where assisted shopping creates durable value.
Named operator cases
The result, how to use it, and what to replicate
Amazon Rufus
Amazon reported 300 million-plus users in 2025 and nearly $12 billion in incremental annualized sales attributed to Rufus.
Apply the finding
Apply this pattern by measuring the eligible audience, retained margin, returns, and repeat behavior alongside conversion.
Treat conversational shopping as a complete funnel and measure exposure through retained contribution.
Walmart
Walmart reports that Trend-to-Product can reduce fashion production timelines by as much as 18 weeks and that AI-supported customer care cut resolution times by as much as 40%.
Apply the finding
Apply this pattern by connecting elapsed-time gains to cost, quality, sell-through, returns, and correction work.
Compress research and preparation while accountable merchants, designers, and service owners retain authority.
Sam’s Club
At more than 120 early locations, Sam’s Club reported that its computer-vision exit system helped all members leave 23% faster before the rollout expanded.
Apply the finding
Apply this pattern by measuring exit time with intervention accuracy, loss outcomes, accessibility, customer experience, and labor deployment.
Remove one measured bottleneck, join physical and transaction evidence, and preserve a staffed fallback.

A practical operating path
From baseline to a defensible scale decision
01
Baseline one journey
Define eligible demand and measure conversion, contribution, returns, contacts, corrections, latency, and customer segments.
02
Contract the truth
Lock the authoritative catalog, price, inventory, policy, identity, consent, and order fields with freshness rules.
03
Run in shadow
Generate answers or rankings without customer exposure and adjudicate unsupported claims, omissions, and stale facts.
04
Release with a comparator
Use randomized or phased exposure and monitor customer errors, exceptions, returns, and operating load.
05
Reconcile and decide
Calculate retained contribution, stress failure and peak demand, then scale, modify, or stop by journey.
Common questions
What operators usually need to know next
What is the best first AI use case for a retailer?
Choose a high-volume, reversible information task with reliable source data: catalog enrichment under review, verified product questions, discovery, or an internal service assistant. Avoid beginning with autonomous pricing, purchase, refund, or account action.
How should a retailer measure AI conversion?
Assign eligible traffic before exposure, preserve a credible comparison group, and measure retained contribution after cancellation, return, discount, fulfillment, service, fraud, platform, review, and redress cost.
What should stop a retail AI pilot?
Stop for unsupported product claims, materially wrong price or availability, unclear purchase consent, inaccessible recovery, cohort harm, unmanageable exceptions, or an apparent gain that disappears after returns and cost.
What changes when an AI system can buy something?
The system needs scoped authority, an explicit order summary, clear confirmation, limited credentials, a durable receipt, cancellation and refund paths, and reconstruction of the data and rules behind the action.
