Commerce has changed considerably in a short period of time. Consumers are more digitally active than ever, mobile now accounts for the majority of purchases globally for the first time, and AI has moved from novelty to a genuine part of how people discover and buy. Each of these shifts raises the bar for what a seamless online checkout experience looks like. Payment flexibility sits at the centre of all of them.

Yet merchant investment in digital capabilities is moving in the opposite direction. The infrastructure decisions being made today are creating a widening distance between what high-value consumers expect and what they find. The more important question is not whether that gap exists. It is where it hurts most, and who is absorbing the cost.

The cost is not evenly distributed

Not all consumers experience the checkout gap equally. The PYMNTS Global Digital Shopping Index points to where the impact is greatest, and the pattern is not random. It tracks almost precisely with the consumers who are most digitally active, most payment-aware, and most willing to take their spending elsewhere when their expectations are not met.

The three segments most affected are high-income earners, millennials, and parents with young children. Understanding why requires looking at how each group shops, not just how often.

High-income consumers bring the highest baseline expectations to every commerce interaction, and the most alternatives when those expectations are not met. They have experienced frictionless checkout in premium retail environments, in travel, in financial services, and they carry those expectations into every transaction. They are also the most likely to use tap-to-pay, digital wallets, and emerging payment methods, and the least tolerant of a checkout experience that cannot accommodate them. The data reflects this. Their gap with merchant capability has grown by 4.6 percentage points in two years. The largest shortfalls sit around convenience and value features: voice ordering, price matching, digital coupons, and loyalty programmes. For a segment that expects commerce to work around them rather than the other way around, these are not minor omissions.

Millennials represent the largest shortfall of any demographic group, and the reason is structural, not incidental. This is the generation that normalised mobile commerce, grew up with one-click checkout, and has spent a decade being conditioned by platforms that treat payment as an invisible layer rather than a hurdle. Their expectations are not excessive. They are simply calibrated to what good already looks like elsewhere. When an online checkout experience falls below that bar, the friction is immediately apparent to them, and the response is often to find a merchant that meets it.

Parents with young children come to checkout with something neither millennials nor high-income consumers prioritise quite as acutely: urgency. Convenience is not a preference, it is a requirement. This segment over-indexes on mobile purchasing, values stored credentials and one-click options, and tends to be among the most loyal customers when a merchant earns their trust through a reliable experience. The inverse is also true. Friction at checkout for this group does not just cost a transaction. It can cost the relationship.

What connects all three segments is that their sensitivity to payment experience is not incidental. It is a function of how frequently they shop, how high their digital engagement is, and how clearly they can perceive the difference between a payment experience built for them and one that is not. Merchants who cannot meet that standard are not just losing transactions. They are losing the compounding value of customers who would otherwise return.

The gap among these segments has widened over the past two years, not narrowed. That trajectory matters as much as the absolute numbers. It suggests that the distance between consumer expectation and merchant capability is not a static problem waiting to be solved. It is an active one, growing with each cycle of consumer adoption that merchant infrastructure fails to keep pace with.

Innovation is stalling at the wrong moment

What makes this more than a conversion problem is the direction of merchant investment. Consumer expectations are rising. The number of digital capabilities merchants are actively planning to build is at a four-year low.

For most merchants, falling behind is not a strategic choice. It is a structural one. The infrastructure many are operating on was built for a different era of commerce, never designed to flex across the channels, payment methods, and customer expectations that define retail today. Capgemini’s World Payments Report 2025, which surveyed senior payments executives across retail and other industries, found that organisations are seriously underprepared for the pace of change in payments, and that stop-gap tactical adjustments are no longer sufficient.

The scale of what merchants are navigating makes that finding harder to dismiss. Digital wallets accounted for 56% of global e-commerce value in 2025, and payment apps are projected to represent 46% of global point of sale value by 2030, according to the Worldpay Global Payments Report 2026. For merchants whose infrastructure was built around cards and traditional online checkout, that trajectory is not a future problem. It is a present one.

The consequence is a compounding problem. Technical debt accumulates. The cost and complexity of change increases with each cycle. And the gap between what merchants can offer and what consumers expect widens in the meantime. For the segments identified earlier, high-income earners, millennials, and parents, this is not an abstract problem. It translates directly into a checkout experience that does not meet their expectations, and a decision to shop elsewhere that becomes habitual over time.

The PYMNTS data captures the trajectory clearly. The feature gaps for these three segments have all widened between 2024 and 2026, not narrowed. Merchants are falling further behind with their most valuable customers, not catching up, and the rate of that drift is accelerating.

The complexity is real, and the scale of change required should not be understated. But the gap, while measurable, is not permanent. The path forward is more practical than the infrastructure challenge might suggest.

Fixing online checkout is more practical than it appears

The merchants closing this gap fastest are not the ones with the largest technology budgets. They are the ones who know where to look, and they are starting with the data they already have.

Baymard Institute estimates average cart abandonment at 70.22% across industries. The leading causes are largely experience-driven: unexpected costs, checkout complexity, trust concerns, and limited payment options collectively account for a substantial share of avoidable online checkout abandonment. That is not a traffic problem or a marketing problem. It is an infrastructure and experience problem with a measurable revenue consequence. For merchants serving high-income consumers, millennials, and parents, the cost of that abandonment is amplified. These are not occasional shoppers weighing up options. They are high-frequency buyers with high expectations, and when the experience falls short they do not complain. They leave.

The starting point for closing that gap is rarely a complete rebuild. It is understanding where the highest-cost friction points are, and addressing them with infrastructure built for how commerce actually works today. That means consistent payment acceptance across every channel a customer might use: in-store, online, and mobile, without the experience degrading as it moves between them. It means offering the payment methods customers actually want to use, not just the ones that were easiest to integrate years ago. And it means protecting transactions in a way that adds security without adding friction, because authentication that slows checkout is its own form of abandonment driver.

What a consumer chooses to pay with reveals something about who they are. High-income consumers over-index on tap-to-pay and digital wallets. Millennials expect one-click. Parents want stored credentials. Matching payment method availability to segment preference is less a technical decision than a customer strategy.

Delivering that experience consistently depends on how payment credentials are handled behind the scenes. Storing payment credentials securely and enabling returning customers to complete purchases without re-entering card details removes one of the most consistent sources of checkout friction. For the segments most sensitive to experience quality, the ability to pay in one tap, with a stored credential, on any device, in any channel, is not a premium feature. It is a baseline expectation. Merchants who meet it see it in their conversion rates. Those who do not see it in their abandonment data.

Fraud and authentication sit alongside this. The instinct is often to treat security and conversion as competing priorities, tightening controls at the expense of experience. The better approach is authentication that is intelligent enough to step up only when genuinely needed, applying friction where risk is real and removing it where it is not. For high-volume merchants serving valuable customer segments, the difference between blunt fraud controls and risk-based authentication is measurable in revenue terms, not just risk metrics.

Underlying all of this is data. Every transaction a merchant processes carries information about how their customers want to pay, where they drop off, which methods drive completion, and which segments are most sensitive to specific friction points. Most merchants are sitting on that insight without fully using it. The businesses pulling ahead are the ones treating their payment data as a strategic input into infrastructure decisions, not a byproduct of operations. Knowing where the gap is largest, for which customers, and in which channels, is what turns a broad modernisation challenge into a set of specific, addressable priorities.

Where this leaves merchants

The PYMNTS findings are most valuable not as a snapshot of where things stand, but as a signal of where they are heading. The always-on, mobile-first, payment-sensitive consumer is not an emerging profile. It is an accurate description of the most valuable shoppers in the market today, and their expectations are only moving in one direction.

The merchants who will capture that value are not necessarily the largest or the best resourced. They are the ones who recognise that payment infrastructure is no longer an operational consideration sitting below the line. It is a commercial one sitting at the centre of how customers are won, retained, and grown.

The gap is real. The direction is clear. The question is whether merchants move toward it deliberately, or are pulled toward it by the cost of standing still.
