Once you've decided a redesign is worth doing, the next question is almost always "okay, but what actually happens, and how long does it take." Vague answers here ("it depends on scope") are technically true and completely unhelpful. This is the realistic version: what a standard B2B WordPress redesign looks like week by week, and where timelines actually slip.
Weeks 1-2: Discovery
Stakeholder interviews, a technical audit of the current site, and a content and SEO review to understand what has to be preserved versus what can change. This phase ends with a scoped project brief, not a design, that both sides agree defines the project. Skipping or rushing discovery is the single most common cause of scope disputes three months later.
Weeks 3-4: UX and Wireframing
Information architecture and low-fidelity wireframes for key page templates, homepage, service pages, resource pages, mapped against the content structure discovery surfaced. This is where the site's actual navigation and content hierarchy get decided, before anyone's looking at colours or fonts, which keeps design feedback focused on structure rather than taste.
Weeks 5-7: Visual Design
High-fidelity design for the approved wireframes, typically two rounds of feedback before sign-off. This is the phase most prone to scope creep if sign-off isn't treated as a real decision point, revisiting approved wireframe decisions here costs real time, since visual design built on a since-changed structure often needs rework, not just a tweak.
Weeks 8-13: Development
The custom theme gets built against the approved designs: template development, any custom plugin or block work, integrations, and content migration into the new structure. This is the longest phase and the one clients see the least of day to day, which is exactly why regular progress updates, not just a single reveal at the end, matter for keeping trust intact through a quiet-looking stretch.
Weeks 14-15: QA, SEO, and Launch
Cross-browser and cross-device testing, a full SEO redirect audit if URLs are changing, performance testing against Core Web Vitals targets, and a staged launch with the new site running in parallel before final cutover. See our signs your site needs a redesign piece if you're still deciding whether to start this process at all, and our cost breakdown for what each phase typically costs.
The two things that reliably extend this timeline aren't development speed, they're content delivery and sign-off discipline. A client who can't get final copy and images to the team on schedule, or who reopens approved design decisions two phases later, adds weeks that have nothing to do with how fast anyone can build.
What to Actually Watch For
Ask any agency proposing a redesign what happens if content isn't ready on time, and whether their timeline assumes you'll hit every delivery date. A realistic proposal builds in some buffer and is upfront about what causes slippage. A proposal that promises an aggressive timeline with no acknowledgement of these risks is either inexperienced or setting expectations it won't meet.
FAQ
How long does a B2B WordPress redesign actually take?
A standard B2B redesign, discovery through launch, typically takes 8 to 12 weeks. More complex projects involving portals, membership functionality, or deep integrations range from 12 to 20 weeks. Timelines stretch mainly from slow content delivery on the client side and scope changes mid-project, not from the development work itself.
What causes redesign timelines to slip?
The two most common causes: content that isn't ready when design and development need it, and scope changes introduced mid-project after wireframes are already approved. Both are avoidable with a clear content plan agreed before kickoff and a change process that treats new requests as a scoped addition rather than a free-form addition to an already-agreed timeline.
Who needs to be involved from our side, and when?
Marketing leadership for discovery and stakeholder interviews, a content owner throughout who can deliver copy and assets on the agreed schedule, and a decision-maker for design sign-off who won't reopen approved decisions later. The single biggest timeline risk is a design sign-off from someone who isn't actually the final decision-maker.
Does the site stay live during the redesign process?
Yes. The new site is built and tested in a staging environment while your current site continues running normally. The only downtime, if any, is a brief cutover window at launch, typically minutes, not hours, when DNS points to the new site.
