Most businesses believe they're accessible. They have a ramp out front, a wheelchair symbol on the restroom door, and a website that technically passes some compliance checklist. Job done, right?

New research published in the Journal of Services Marketing suggests otherwise — and the gap between what companies think they're doing and what disabled customers actually experience turns out to be significant, costly, and, crucially, fixable.

The paper, lead by Dr Mirzaei, an Assistant Professor in Marketing at Macquarie Business School, introduces two frameworks built from an analysis of over 24,700 online conversations sourced from disability-focused Reddit forums. Rather than relying on surveys or focus groups, the researchers relies on vulnerable consumers own words, raw, unfiltered accounts of what it actually feels like to try and buy a coffee, get groceries delivered, or navigate a phone support queue when the system wasn't designed with you in mind.

What they found should make any service-oriented business uncomfortable.

The Problem With How We Define Vulnerability

For decades, the dominant approach to "vulnerable consumers" has been demographic. You're vulnerable if you're elderly, disabled, or low-income — fixed categories that businesses can then tick off and address with targeted programs. The problem, the researchers argue, is that this model is almost entirely wrong.

Vulnerability isn't a trait people carry around. It's something that gets created, and recreated, every time a person interacts with a service that wasn't built for them. A delivery driver who leaves a heavy parcel in the lobby because he didn't read the access note. A support agent who sighs audibly when asked for a longer appointment. A policy change, implemented overnight, that removes an accommodation someone had relied on for years. Each of these interactions doesn't just fail the customer in the moment, it compounds. It creates what the researchers call experienced vulnerability: a growing weight of anxiety, self-doubt, and anticipatory dread that shapes every future interaction.

One consumer quote in the paper captures this perfectly: "I don't love telling every delivery person who brings me groceries that I'm disabled. I pay for delivery, have no control over the shipping service... and I'm left stressing about how I'm going to get packages left at a pickup location when I don't have a car."

This isn't a wheelchair ramp problem. It's a systems problem.

The VCX Framework: What Vulnerable Customers Actually Need

The researchers distil their findings into a Vulnerable Consumer Experience (VCX) framework built around three dimensions: expectations, sensitivities, and responses.

Expectations, for disabled consumers, go well beyond speed or convenience. They want independence — not special treatment, but the same autonomous experience everyone else gets. They want consistency, because predictable accommodations are the scaffolding around which they organise their lives. And they want functionality that simply works, without requiring them to prove they deserve it.

Sensitivities reveal how finely tuned the emotional stakes are. Vulnerable consumers are acutely attuned to tone and manner — a dismissive word, a raised eyebrow, a staff member who clearly doesn't want to deal with the complexity of their needs. They are also intensely sensitive to time and energy, because the cognitive and physical load of navigating inaccessible systems competes directly with work, caregiving, and managing pain. Every redundant step costs something real.

Responses, finally, fall into three patterns. Some consumers withdraw entirely through aversion — avoiding companies or whole industries after enough bad experiences. Others amplify, going public, reporting, even litigating, to force systemic change. And many simply adapt: paying for workarounds, limiting participation, suppressing their needs to stay under the radar. As the researchers note, this last category "comes at great personal cost" and is too often mistaken by businesses for satisfaction.

The RAMP: A Practical Playbook

This is where the paper shifts from diagnosis to prescription, introducing the Reasonable Accommodation Management Plan (RAMP). Across three pillars — flexible and affordable offerings, service design and delivery, and technology and innovation — the framework gives businesses concrete directions.

On offerings: flexible payment models, extended trial periods, and modular services that let consumers build what they actually need. On design: rethinking physical and digital environments, offering remote and at-home service options, and training staff in adaptive communication. On technology: using AI not to replace human interaction but to reduce friction, manage cognitive load, and offer low-stress pathways for consumers who dread the phone queue.

The researchers are careful to note that technology alone solves nothing if the underlying culture stays the same. AI chatbots and voice shopping are enablers, not substitutes for genuine inclusion.

What this research ultimately argues is that treating vulnerable consumers well isn't a compliance exercise — it's a commercial and ethical imperative. Businesses that get this right don't just avoid alienating a significant market segment. They build the kind of trust that turns into lifetime loyalty.

The ramp, it turns out, leads somewhere worth going
