Making a Shopify store accessible is mostly a question of order, not of budget. Most of the barriers that block screen reader users and that draw legal attention are concentrated in a small number of recurring issues: missing alt text, low color contrast, unlabeled form fields, and broken keyboard focus. None of those require a redesign. They require theme edits. The cost and effort depend almost entirely on whether you fix the right things first or spread effort thin across everything at once.
This article lays out what accessibility work actually costs in time and money, what drives those numbers up or down, and the order that gets you the most coverage for the least effort.
What "accessible" actually means here
There is no single button that makes a store "accessible." The working standard, in both the US and the EU, is the Web Content Accessibility Guidelines (WCAG). In the EU, the European Accessibility Act (EU Directive 2019/882) requires e-commerce sites above the microenterprise threshold to meet WCAG 2.1 AA through the harmonized norm EN 301 549. In the US, courts applying the Americans with Disabilities Act (ADA) Title III have treated WCAG as the reference for what an accessible website looks like, most notably in Robles v. Domino's Pizza, 913 F.3d 898 (9th Cir. 2019), where the 9th Circuit held that a website tied to a physical place of public accommodation falls under the ADA.
So the target is WCAG conformance, usually at level AA. The relevant detail for budgeting is that WCAG is a list of testable success criteria, by number and level. You do not have to guess what "good enough" means. You can measure against specific criteria like 1.1.1 (non-text content), 1.4.3 (contrast minimum), and 2.4.7 (focus visible), and track which ones pass.
One thing accessibility is not: an overlay. Overlays are runtime JavaScript widgets that adjust appearance in the browser after the page loads. They do not change the underlying source code, which is what courts and audits actually assess. In January 2025 the US Federal Trade Commission settled with accessiBe, the largest overlay vendor, for 1 million USD and prohibited the company from claiming its product alone makes a site ADA or WCAG compliant. If your plan is to pay for an overlay and consider the job done, the cost is low and the result is close to zero. We covered why in detail in why accessibility overlays do not protect against ADA lawsuits.
Where the cost actually goes
Accessibility cost breaks into three buckets, and they are not equal.
- Finding the barriers. This is the cheapest part if you use an automated scanner, and the most expensive if you hire a full manual audit. A scan of your theme can surface most of the high-frequency, code-level issues in minutes.
- Fixing the barriers. This is the bulk of the effort. The cost depends on whether the fix is a one-line theme edit (most contrast and label issues) or a structural change (a custom section built with the wrong markup).
- Keeping it fixed. Every theme update, new app, and new product can reintroduce a barrier. Ongoing cost is real but small if you scan periodically rather than re-auditing from scratch.
The trap is spending most of your budget on bucket one. A single point-in-time manual audit produces a long PDF, and then the actual fixing still has to happen. For most Shopify merchants the smarter sequence is: scan cheaply, fix the high-frequency issues yourself in theme code, then bring in a manual expert only for the parts a machine cannot judge, such as whether alt text is meaningful or whether a custom widget is operable.
The right order: fix what blocks the most users first
Not all barriers are equal. Some block an entire category of users from completing a purchase. Some are minor inconveniences. Effort spent on the first group is worth far more. Here is the order that delivers the most coverage per hour.
1. Color contrast
Low contrast text affects the largest number of real users, including everyone with low vision and anyone shopping in bright light. It is also one of the most common WCAG failures (criterion 1.4.3 requires 4.5:1 for normal text). The fix is usually a color token change in your theme's CSS, applied once, affecting the whole store. High impact, low effort. This is why it comes first. See our guide to fixing color contrast in Shopify themes.
2. Alt text on product images
Screen reader users cannot shop a catalog of images with no text alternatives (criterion 1.1.1). For a store with hundreds of products this is the most time-consuming single task, because good alt text is written per image, not generated by a guess. But it is also high impact, since product images are the core of the buying decision. Plan for this to take real time and prioritize your best-selling products first. We break down the approach in accessible alt text for Shopify products.
3. Form labels and keyboard focus
If a blind or motor-impaired user cannot reach and complete the cart, search, and checkout flows with a keyboard and a screen reader, they cannot buy. Unlabeled form fields (criterion 1.3.1, 4.1.2) and invisible focus indicators (criterion 2.4.7) are the issues most directly tied to lost sales and to litigation, because they sit on the conversion path. These are theme-code fixes, often a <label> element or removing an outline: none rule.
4. Headings, landmarks, and structure
Correct heading order and page landmarks let screen reader users navigate without reading every word. Lower urgency than the first three, but cheap to fix while you are already in the theme files.
5. Everything a machine cannot judge
Whether alt text is actually meaningful, whether a custom slider is operable, whether an error message is clear: these need a human. Save your manual-audit budget for here, after the bulk fixes are done, so the expert reviews a clean store instead of an obvious one.
