Yes, you may draw up an improvement plan for accessibility yourself. There is no obligation to have this done by an external party, and there is no prescribed format that it must comply with. What does matter is that the plan is concrete: which barriers have been found, who will address them, and within what timeframe.
The boundary between doing it yourself and outsourcing lies not in drawing up the document itself, but in the substantive choices within it. Identifying that a checkout step cannot be operated using only a keyboard is different from determining how that step must be technically adapted to comply with WCAG 2.1 level AA. The latter requires knowledge of the standards, and often also understanding of the technology behind your specific website or app.
What an improvement plan contains in practice
An improvement plan is at its core a list of findings, ordered by what weighs most heavily. A missing alternative for a product photo is inconvenient, but a checkout button that is unfindable for a screen reader prevents a sale. Supervisory authorities and users look at that kind of difference in severity, and a plan that lumps everything together is useful to no one.
In addition to the findings, there must be a schedule: what will be resolved when, and by whom. The latter is usually an internal responsible party, not necessarily the party that identified the barriers. An improvement plan is therefore also an organisational document, not merely a technical report.
Where doing it yourself stops
The most challenging part is not the writing, but the prioritisation. Which barriers affect the most users, which are in a mandatory step such as checkout or login, and which can be resolved with limited effort? Without a prioritised list as a starting point, an improvement plan quickly becomes a list with no order, making it difficult to demonstrate that you have proceeded seriously.
This is also why an automated scan never gives the complete picture: it tests part of the requirements, and that is stated in every report. Matters such as the logical reading order of a page for a screen reader, or the correct meaning of a link text in context, require assessment that a scan cannot fully provide. Those who understand this can judge for themselves which part of the plan can be tackled independently and which part requires targeted knowledge.
Axessia.eu does not carry out manual audits or remediation work itself. What the system does do is run the scan across the core pages and, with a subscription, also across the checkout step and login flow, and translate the results into a prioritised list in plain language. That list is the starting point for an improvement plan, not the plan itself. clarified per topic what is expected of you provides an overview of what should be included in such a plan and what is regulated elsewhere.
Recording and monitoring
An improvement plan is not a document you write once and then file away. After every change to the website or app, it should be determined again whether previously resolved barriers remain resolved, and whether new components comply with the same requirements. That recording — what has been found, what has been resolved, and when — is precisely the part included with a subscription: templates to make your own assessment demonstrable and a notification as soon as something affects your situation.
Anyone dealing with this subject for the first time should first determine what the law actually covers. see in a few questions where your website or app currently stands provides an initial indication without requiring an account. If you still have doubts about the legal aspects of a specific situation, a lawyer or the competent market surveillance authority remains the appropriate party to assess that; this article describes the standards in general terms, not your individual case.
You can draw up an improvement plan yourself, and in part that is also practical: no one knows the internal organization better than you do. What matters is that the underlying findings are correct and prioritized, and that the plan is updated after each change. answers to questions that other businesses have already asked shows which concerns about it come up most frequently.
