Work management platforms frequently change their web addresses. Technical migrations, acquisitions, rebranding: the reasons are numerous, and the result is the same for the professional user. A favorite that no longer works, a 404 error page, and several minutes wasted searching for the correct link. This phenomenon affects both independent craftsmen and construction companies that rely on these tools for their quotes, invoicing, and project tracking.
Why a work management platform’s URL changes
A change of web address is almost never trivial. Behind a simple redirection often lies an infrastructure migration, a domain name change after an acquisition, or a technical compliance update. SaaS platforms designed for construction professionals evolve quickly, and their URL changes accordingly.
The most common case remains rebranding. A platform changes its commercial name, merges with a competitor, or restructures its services. The old address may work for a few months thanks to an automatic redirection, then stop responding. Users who had saved the old link in their favorites or password manager find themselves blocked.
To regain functional access, the most reliable reflex is to consult the official communication from the publisher. In the case of Batiav.com, for example, a detailed guide allows users to find the new URL of Batiav.com without relying on potentially outdated search results.
One point rarely mentioned: 301 (permanent) redirections are not always maintained indefinitely by publishers. Relying on the old link to access the service, even if it works today, offers no medium-term guarantee.
Multifactor authentication and access to BTP platforms in 2025-2026
Beyond the simple URL change, the way users connect to a project management platform is changing due to regulation. The CNIL deliberation no. 2025-019 of March 20, 2025 now regulates multifactor authentication (MFA) and considers it “generally necessary” for sensitive processing and remote access.
For a craftsman or a construction company managing quotes, invoicing, and client data on an online platform, this recommendation has direct consequences. Software publishers for work management must adapt their login processes. In practical terms, this means that a simple username/password combination may no longer be sufficient to access one’s professional space.
What the CNIL has been monitoring since early 2026
Since early 2026, the CNIL has announced a specific strengthening of its controls regarding the presence of multifactor authentication for remote access to information systems. The absence of MFA can now trigger a sanction procedure.
Field feedback varies on this point: some industry platforms have already deployed double authentication via SMS or dedicated application, while others still rely on a strengthened password. The measurable progress of MFA in French TPE-PMEs between 2024 and 2025, as reported by the Cybermalveillance.gouv.fr barometer, shows that adoption remains uneven depending on the size of the company.
For the user, this adds a step at the time of login, but MFA protects project, quote, and client data against unauthorized access. During a URL change, it also serves as a signal of reliability: a platform that migrates its address while strengthening its authentication takes security seriously.
Regaining access after a migration: concrete checks
When a work management platform changes its address, the main risk is not losing data (which remains on the publisher’s servers), but wasting time reconstructing access. A few systematic checks can help avoid blockages.
- Update the favorite or saved shortcut in the browser with the new official URL, rather than relying on a temporary redirection that may expire.
- Check that the password manager correctly associates the credentials with the new address. Some managers do not automatically follow redirections and may offer a blank form on the new domain.
- Ensure that MFA (if configured) still works after the migration. A domain change can sometimes reset the dual authentication settings linked to the old domain.
- Check the access of collaborators linked to the business account. On platforms that manage rights by structure, each user must individually confirm their access after a URL change.
The trap of links shared in professional exchanges
Quotes, invoices, and project tracking documents are often shared via email or messaging with direct links to the platform. After a change of address, these links may become invalid. A client or subcontractor clicking on an old quote link risks landing on an error page.
The available data does not allow us to conclude that all publishers maintain redirections on shared document links. However, the most structured platforms generally offer a permalink system that survives migrations. This is a criterion to check with the publisher’s support before or just after the transition.
Data portability and changing project management platforms
A change of URL can also be the moment to ask a broader question: should one stay on this platform or migrate to another work management software? Data portability is a right, but its practical implementation varies significantly from one publisher to another.
The export formats offered (CSV, PDF, proprietary formats) determine how easily one can retrieve their history of quotes, invoicing, and project tracking. A PDF-only export makes any migration to a competitor cumbersome, as the data cannot be automatically reused.
For construction companies managing multiple projects simultaneously, the question of client relationships also comes into play. Client contact details, exchange history, signed documents: all of this must be able to follow in case of a tool change. Before validating a new URL in their favorites, checking export options remains a useful precaution.
The change of address of a work management platform, whether it is Batiav.com or another tool, is never just a technical detail. It is an opportunity to review access, check the security of the connection, and assess whether the tool still meets the real needs of the business.
