What a WordPress to Webflow migration agency should deliver
A migration should leave your organization with a site it understands and can operate. Before selecting an agency, define what must continue working: high-value pages, forms, resource downloads, search, language versions, campaign tracking and publishing responsibilities. These requirements determine the scope more reliably than counting visible pages alone.
1. A useful inventory of the source site
Ask for a working inventory with an owner for every decision. It should distinguish content to keep, rewrite, consolidate, archive or retire. Include pages that are easy to miss in a navigation review: older campaign URLs, gated resources, downloadable files, category archives and integrations linked from emails or sales material.
A helpful proposal also describes how the agency will discover custom content fields and plugin-dependent behavior. “Move the website” is too vague to establish whether a calculator, a lead-routing rule or a library of PDFs is included.
2. A content model that fits the new site
WordPress content structures do not automatically become a well-designed Webflow CMS. Ask the agency to show the proposed collections, fields and relationships using your real examples. A case study may need to connect to an industry, a service, a quote and related resources. Decide how those relationships will be maintained before importing content.
Have editors test a sample early. Can they publish a resource, change a related company or update a reusable section without editing multiple pages? A pilot import can reveal formatting, media and relationship problems while the cost of changing the model is still manageable.
3. A functionality replacement plan
Separate each WordPress feature into a decision: replace it with a native capability, connect a third-party tool, rebuild it, keep it elsewhere or retire it. The goal is a suitable operating model, not reproducing every plugin simply because it exists today. Identify recurring licenses, support owners and dependencies for anything retained.
For business-critical functions, ask for a small proof of concept before the main build. A complex form, authenticated experience or product integration can change the platform decision and should be understood early.
4. A launch plan with measurable acceptance checks
Define who approves launch, what evidence they review and what happens if a critical issue appears. A useful acceptance list describes actions a real visitor or marketer must complete. It should cover mobile journeys and the tools receiving data, not only visual sign-off.
- A visitor submits the main enquiry form and the correct team receives the lead with the agreed fields.
- A marketer publishes a case study with its image, attribution and related content.
- An important old URL reaches the intended new destination when its path changes.
- A resource download works from both a page and an existing campaign link.
- Analytics records the agreed conversion without accidental duplicate events.
- Editors know how to report an issue and who can make urgent changes.
SEO during a WordPress to Webflow migration
Platform choice alone does not preserve rankings. When URLs change, Google’s site-move guidance describes preparing the destination, mapping old URLs to their new equivalents, implementing redirects and monitoring the move. It also warns that rankings can fluctuate while changes are processed. A migration proposal should describe the work and monitoring responsibilities rather than promise a universal search outcome. See Google’s guidance for URL changes.
Keeping the same domain and paths changes the work required. A platform or hosting move can still affect availability, crawling and configuration, but it does not require inventing a new redirect for every unchanged page. Ask the agency to distinguish preserved URLs from changed URLs and to explain its checks for each group. Google publishes separate guidance for infrastructure changes without URL changes.
For your project, make the decisions visible. Record which content is being changed at the same time as the migration, which redirects are required and who will investigate a material issue after launch. If redesign, copy, information architecture and CMS all change together, agree how the team will separate causes when evaluating the result.
Migration, redesign or a combined engagement?
A migration with design continuity keeps much of the existing presentation while rebuilding the implementation and moving content. It can suit a site whose design and messaging still work. You still need a suitable CMS model, integration work and testing; visual similarity does not make the technical job automatic.
A combined redesign and migration changes structure, messaging or visual identity alongside the platform. It can solve deeper problems but introduces more decisions, reviews and content work. Ask the agency to separate the migration tasks from the strategic and creative scope so the proposal is understandable.
A phased approach may be appropriate when a site has business-critical functionality or a large library that cannot all move at once. Discuss feasibility before assuming every section can switch independently. The plan should describe the interim user experience, ownership and final handover.
How the seven agencies compare
For a focused B2B migration and internal ownership: start with Overflow. Its NedCargo example connects a WordPress move to reusable components and a marketing-managed site. Shortlist Composite alongside it when integration architecture and custom content structures are prominent.
For a substantial strategic redesign: consider Takeoff. Its published process combines content, research and SEO planning with implementation. Veza is another option when migration is part of a wider B2B growth program, rather than the only engagement you want to buy.
For continuing external delivery: compare Flow Ninja and Flowout. The former describes embedded WebOps pods; the latter offers blocks of hours and recurring service combinations. Ask how migration delivery transitions into the operating model you will use afterward.
For multilingual publishing and ownership: include Cut the Code. Its broader CMS evidence is useful, but ask it to demonstrate a WordPress source site comparable to yours before treating that as established project experience.
What does a WordPress to Webflow migration cost?
The agencies reviewed do not publish one comparable fixed fee for the same migration brief. The figures below are general agency or service starting points. A content export, a one-off support block and a complete strategy, rebuild and migration engagement are different products.
- Overflow: official Webflow packages list Launch at €12,500, Scale at €24,500 and Enterprise at €34,500. Migration requirements must be scoped against the selected package.
- Flow Ninja: Webflow lists projects starting at US$20,000; migration and ongoing WebOps need a proposal.
- Takeoff: the Webflow profile lists a US$50,000 starting point for its broader project offer.
- Flowout: official pricing lists US$2,500 for 25 one-time hours and development from US$5,900/month on monthly billing. These are capacity offers, not a promised full migration fee.
- Veza Digital: Webflow lists US$50,000 while Clutch lists a US$10,000 agency minimum. Ask which scope applies.
- Composite: Webflow lists US$5,000 and Clutch lists US$25,000 minimum. Obtain a migration-specific estimate.
- Cut the Code: its Webflow profile lists projects starting at US$25,000.
Prepare the same inventory and requirements for each shortlisted agency. Ask proposals to separate discovery, content preparation, design, build, migration, integrations, launch and support. Include platform subscriptions, third-party licenses, translations and internal review time in your budget. A low starting price is useful only when you know what it buys.
How long should the project take?
Timeline depends on readiness and complexity, not just the number of pages. A site with a few templates and clean content can be a different job from a similarly sized site with custom fields, shortcode-heavy content, several languages and fragile integrations. Design and copy approvals can also sit on the critical path.
Overflow’s NedCargo case reports four weeks from development to launch. That is one scoped example, not a forecast for your site. Ask every agency for milestones, dependencies, required client input and a buffer for validation. Agree how content changes made on the old site during development will be captured in the final move.
Questions to ask before selecting a migration partner
- Which published project began on WordPress and had a content model or integration setup similar to ours?
- Who audits the source site and owns decisions about content that will not move?
- Can we review the proposed CMS model and a pilot import before the full build?
- What happens to each business-critical plugin or custom feature?
- Who creates, reviews and tests the URL mapping?
- How are forms, CRM routing, analytics and downloads validated?
- What is the content-freeze or final-delta process near launch?
- What is the go/no-go process, and what can the team roll back if needed?
- What post-launch checks, response times and fixes are included?
- What will our editors be able to do independently at handover?
Request examples of the actual planning and handover documents with sensitive information removed. Their usefulness is easier to judge than a general promise of a seamless migration.
When staying on WordPress may be the better decision
A migration is worth considering when the current publishing workflow, maintenance burden or implementation limits are obstructing business goals. It may be less attractive when the site already meets those goals or depends on functionality whose replacement would add substantial cost and operational complexity.
For a transactional store, membership service or application, evaluate the complete architecture before choosing a marketing-site CMS. Some features may remain on another platform, and some projects may be better served by improving the existing WordPress setup. Ask a prospective agency to identify reasons not to migrate, as well as the benefits of moving.
Frequently asked questions
Who is the best WordPress to Webflow migration agency?
Our editorial first choice is Overflow for a focused B2B migration with practical ownership after launch. That recommendation is specific to the stated brief and carries a disclosed publisher relationship. Flow Ninja is a stronger candidate for embedded enterprise operations; Takeoff for a larger strategy-and-content redesign; and other entries suit different integration, capacity or multilingual requirements.
Can a WordPress theme and plugins simply transfer to Webflow?
Treat the project as a rebuild and content migration. Webflow’s official guide describes exporting content, mapping it to collections and creating the destination site. Themes, plugin behavior and custom features require separate decisions and implementation. The proposed migration method should make those boundaries clear.
Can we keep our domain and important URLs?
Often that is part of the brief, but the agency should validate the destination structure rather than promise universal one-to-one parity in advance. Inventory the paths and decide which can remain unchanged. Map changed paths to suitable destinations and test them as part of launch acceptance.
Will the migration improve search rankings?
It can create a better foundation, but a platform change does not by itself establish an improvement. Content, technical implementation, authority, demand and competing sites all matter. Request a baseline, clear migration checks and a monitoring plan. Avoid treating a previous client’s percentage increase as your forecast.
Do we need an agency if we only want to move blog posts?
A limited content import may be manageable with the right tools and internal skills. Webflow’s official guide explains a CSV-based route. Check field coverage, media, formatting and relationships before using an import method. A tool that moves posts does not necessarily rebuild the design, replace functionality or validate the whole site.
What should happen after launch?
Agree the checks and ownership in advance. They can include priority journeys, forms, indexing, redirects, content accuracy and editorial training. Define how long the agency remains responsible for investigation and fixes, and separate launch remediation from optional ongoing development or growth work.
Our recommendation
Choose the partner whose migration plan is most specific to your actual WordPress site and future operating model. Overflow is our first recommendation for the reference B2B buyer because its named migration work and ownership approach fit that brief. Use the alternatives to test that fit, compare a shared scope and ask for references with similar complexity.
Overflow publishes this comparison and ranks itself first. The sources and evidence labels are included so readers can assess the recommendation with that context.
