When your platform stops keeping up with your mission, it's time to consider the switch, but only if it's actually worth it.
Here's something you won't hear from most WordPress agencies: Wix and Squarespace are genuinely good platforms.
They're affordable, easy to use, and perfectly adequate for nonprofits with straightforward brochureware sites. If your organization has a simple website with a few pages, a contact form, and maybe a basic donation button, there's no urgent reason to leave.
But you're probably not reading this because everything is working fine.
You're reading this because something has started to break down. Maybe your recurring donation options are limited. Maybe your membership database can't talk to your website. Maybe you've tried to add event registration or a member portal and hit a wall. Or maybe you're just tired of workarounds that almost do the job.
That's the inflection point we see constantly with growing nonprofits: the platform that got you started is now holding you back.
This guide will help you determine whether migration actually makes sense for your organization, what's really involved, and how to make the transition without disrupting your fundraising. Whether you're considering a Wix to WordPress migration or a Squarespace to WordPress migration, we'll walk you through the nonprofit-specific concerns that generic guides ignore. We'll also be honest about when it's the smarter choice to stay put.
If you're migrating from a nonprofit-specific all-in-one platform instead, we have dedicated guides for Wild Apricot, SilkStart, and Flipcause, each covering the platform-specific challenges those migrations involve.
Signs Your Nonprofit Has Actually Outgrown Wix or Squarespace
Not every frustration requires migration. But certain patterns signal that you've hit genuine platform limitations rather than just learning-curve issues.
Donation and fundraising constraints are usually the first sign. If you can't offer flexible recurring giving options, can't customize your donation forms to match campaign needs, or find yourself paying excessive transaction fees through the platform's built-in tools, you're bumping against real limits. WordPress with a proper fundraising plugin, such as GiveWP or Charitable, offers significantly more flexibility.
CRM and database integration problems often surface next. Your donor management system, association management software, or membership database needs to sync with your website, but the platform offers limited or no integration options. You end up with manual data entry, duplicate records, and constituent information scattered across disconnected systems.
Membership and gated content limitations become painful as your organization matures. You need member-only resources, tiered access levels, or single sign-on integration with your AMS. Wix and Squarespace's membership features are improving, but they're still nowhere near what's possible with WordPress and proper membership plugins. (See why FatLab excels at nonprofit membership sites for more on this.)
Accessibility and compliance requirements can be the deciding factor. If your organization needs to meet WCAG accessibility standards, increasingly common for nonprofits receiving government funding, you'll find Wix and Squarespace's options limited. WordPress offers far more control over accessibility implementation. For guidance on what WCAG compliance actually requires, see our nonprofit website accessibility guide.
Event management complexity is another trigger. Basic event listings are fine, but when you need registration, ticketing, capacity management, waitlists, and CRM integration, the built-in tools fall short.
Traffic and performance at scale occasionally drives the decision. If your site experiences major traffic spikes during campaigns, giving days, or media coverage, you may need infrastructure that can scale more aggressively than these platforms allow. If hosting costs or quality are part of your frustration, our breakdown of 7 signs your nonprofit is overpaying for hosting can help you evaluate whether a switch is overdue.
When Migration Doesn't Make Sense
Let's be clear: migration isn't always the right answer.
Suppose your primary frustration is with your site's design or content, not its functionality. In that case, you probably don't need to switch platforms. You need a redesign or content refresh, which you can do on your current platform.
If the budget is extremely tight and you don't have staff capacity for a more complex site, WordPress's greater flexibility comes with greater maintenance requirements. You'll need either technical staff or a managed hosting partner (like us) to handle updates, security, and ongoing maintenance.
If your site is genuinely simple and your complaints are minor inconveniences rather than genuine blockers, the cost and effort of migration may not be justified.
We regularly tell organizations that they're not ready to migrate, or that the ROI doesn't make sense for their situation. There's no point in moving to a more powerful platform if you don't actually need that power.
Why Nonprofits Choose WordPress (When They're Ready)
When migration does make sense, WordPress offers specific advantages that matter to mission-driven organizations.
Ownership and portability top the list. With Wix or Squarespace, you're renting space on their platform. With self-hosted WordPress, you own your site completely. You can move hosts, change developers, or modify anything without platform restrictions. This matters for organizations building long-term digital infrastructure.
Fundraising flexibility transforms what's possible. WordPress donation plugins offer recurring giving with custom frequencies, peer-to-peer fundraising, tribute and memorial gifts, goal tracking, donor walls, and deep integration with payment processors like Stripe and PayPal. You're not limited to whatever the platform has decided to build. (We compare the leading options in our WordPress donation system solutions guide.)
A true CRM and AMS integration becomes achievable. WordPress can connect with Salesforce, Blackbaud, HubSpot, NeonCRM, CiviCRM, and virtually any system your organization uses. Data flows where it needs to flow. (For a deeper dive on this topic, see our guide to professional CRM and AMS integration for nonprofit websites.)
Accessibility control lets you meet compliance requirements. You can implement WCAG guidelines, add proper ARIA labels, ensure keyboard navigation, and audit for issues, things that are difficult or impossible on closed platforms.
Long-term cost efficiency often favors WordPress. While upfront migration costs exist, ongoing costs can actually be lower, especially when you're not paying platform transaction fees on donations or premium pricing for features that are standard in WordPress.
The Question Every Nonprofit Actually Cares About: Donation Continuity
Let's address the elephant in the room. The number one concern we hear from nonprofit leaders considering migration is: "What happens to our donations during the switch?"
It's a legitimate fear. Your organization depends on that revenue. A fumbled transition during a major campaign, or even a quiet giving period, could mean real financial impact.
The honest answer: it depends on your current setup, and this is one of the first things we assess.
Best-case scenario: gateway continuity. If you're currently using Stripe or PayPal directly, even through Wix or Squarespace, those same processors can connect to WordPress. Your recurring donors are still charged through the processor, and the website is just the interface. We set up new donation forms in WordPress (using a system like GiveWP or a custom solution), connect them to your existing processor accounts, and recurring gifts continue uninterrupted.
Common complication: locked-in systems. Many Wix and Squarespace sites use the platform's built-in donation tools, or embed third-party fundraising platforms' iframes and JavaScript widgets. These systems often don't provide any way to export recurring donor data or migrate payment tokens. You're essentially renting their infrastructure with no path to portability.
In these situations, migrating to a fully integrated WordPress donation system means starting fresh with your payment setup. Recurring donors would need to re-enter their payment information. This isn't the end of the world (we've helped organizations navigate this successfully), but it requires careful communication and timing.
What we do about it:
- Assess your current setup early. Before recommending migration, we determine exactly what you're working with. Can your payment data move with you, or will you have to start over?
- Time the transition strategically. If recurring donors need to re-enroll, we time this during a natural renewal period or pair it with a positive message about upgraded giving options.
- Communicate proactively. We help you craft messaging that frames the transition positively, often as an upgrade that gives donors better receipting, easier management of their giving, or new options like flexible recurring frequencies.
- Minimize friction. The new donation experience should be better than what they had before, making re-enrollment feel worthwhile rather than annoying.
The parallel running period remains critical either way. The new WordPress site runs alongside your existing site during testing. Donation forms are configured and tested with real transactions (which we refund) before anything goes live. Only when everything works perfectly do we make the DNS switch.
Timing still matters. We never recommend migrating during your biggest fundraising push of the year. Year-end giving season? Giving Tuesday? Your annual gala? Those are terrible times to be working on infrastructure. We help you find the right window, often late winter or summer, when transition work won't coincide with major campaigns.
The key is to understand your situation up front so there are no surprises. Some migrations are seamless for donors; others require a managed transition. Either way, proper planning makes the difference.
What Gets Migrated (And What Gets Rebuilt)
Understanding the migration process helps set realistic expectations.
Content that transfers. Your blog posts, pages, and text content can generally be exported and imported. It's not always perfectly clean (you may need to review formatting and fix some quirks), but the content itself moves over.
Content that needs manual handling. Images and media files typically require re-uploading or careful migration. Design and layout don't transfer, so your WordPress site will need a new theme, either custom-designed or adapted from your current look. Navigation structure, menus, and site architecture are rebuilt in WordPress.
Settings that require manual recreation: SEO metadata (page titles, descriptions, etc.) needs to be manually transferred or recreated. Form configurations, email integrations, and third-party connections all need fresh setup on the WordPress side.
Data that stays with your processors: Donation history, recurring gift schedules, and payment information live with your payment processor (Stripe, PayPal, etc.), not on your website. When we connect WordPress to those same processors, your historical data and ongoing subscriptions remain intact.
Design considerations. You have three options for your WordPress design. We can recreate your current look as closely as possible, maintaining brand continuity while gaining WordPress functionality. We can use the migration as an opportunity for a refresh or redesign. Or we can implement a new theme that matches your brand guidelines. Most nonprofits treat migration as a chance to make at least some design improvements, since the site is being rebuilt anyway.
What the Migration Process Actually Looks Like
A professional nonprofit website migration typically moves through distinct phases. Understanding this helps you plan internally and set expectations with your board and staff.
Quick overview: how to move your website from Wix or Squarespace to WordPress:
- Discovery and planning (audit current site, document requirements)
- WordPress setup and design (build on staging environment)
- Content migration (import and clean up pages, posts, media)
- Functionality implementation (donation forms, CRM integration, membership features)
- Testing (thorough QA of all features, especially payment processing)
- Launch (DNS cutover with 301 redirects)
- Post-launch monitoring and team training
Here's what each phase involves in more detail:
Phase 1: Discovery and planning. We audit your current site: every page, form, integration, and piece of functionality. We document what exists, what works, what doesn't, and what you wish you had. This becomes the blueprint for your WordPress site. We also identify your SEO baseline to protect your search rankings.
Phase 2: WordPress setup and design. We build your new WordPress site on a staging environment, a private version that's not publicly visible. This includes hosting configuration, theme development or customization, and core site structure. You'll see the new design taking shape and can provide feedback before anything goes live.
Phase 3: Content migration. Blog posts and pages are imported and cleaned up. Images are transferred and optimized. Navigation and menus are configured. Content is reviewed and refined.
Phase 4: Functionality implementation. This is where the real value emerges. Donation forms are built and connected to your payment processors. CRM or AMS integrations are configured. Membership features, event systems, or other functionality specific to your needs are implemented and tested.
Phase 5: Testing. We test everything. Donation forms are tested with real transactions. Member logins are verified. Contact forms, email notifications, mobile responsiveness, accessibility, and performance are all checked. You and your team get access to the staging site to review and flag issues.
Phase 6: Launch. When everything is approved, we schedule the DNS cutover, the moment when your domain starts pointing to the new WordPress site instead of the old one. We implement 301 redirects so that old URLs automatically forward to their new locations, preserving SEO value and preventing broken links. The old site is kept available briefly as a backup.
Phase 7: Post-launch monitoring and training. We monitor the new site closely in the days after launch, catching and fixing any issues that emerge in the real-world environment. We train your team on WordPress content management so they're confident making updates. Documentation is provided for ongoing reference.
Timeline and What Affects It
Typical nonprofit website migrations take 3-6 weeks from kickoff to launch, depending on several factors.
Site complexity is the primary driver. A 20-page brochureware site with a donation form migrates faster than a 200-page site with member portals, event registration, CRM integration, and multilingual content.
Content readiness matters significantly. If you're migrating content as-is, it's faster. Suppose you're rewriting pages, adding new content, or restructuring your site architecture, which adds time. We often recommend treating migration as a content-cleanup opportunity, but that's a scope decision that affects the timeline.
Internal approval processes can extend things. If every page needs board review, or if your team has limited availability for feedback, build that into expectations. We try to keep the momentum going, but we need your input at key decision points. Suppose you need board approval for the project itself. In that case, we can provide documentation to support that process, including scope summaries, timeline projections, and risk mitigation plans that address common board concerns about website transitions.
Integration complexity varies widely. Connecting to Stripe is straightforward. Custom integration with a legacy AMS that requires API development is not.
Design ambition affects timeline. Matching your current design is faster than creating something entirely new.
Most organizations can complete migration without rushing if they start planning 8-12 weeks before their desired launch date, accounting for holidays, staff vacations, and competing priorities.
Protecting Your SEO During Migration
Website migrations are notorious for damaging search rankings when handled poorly. Pages get lost, URLs change without redirects, and months or years of SEO value evaporate.
This doesn't have to happen.
URL mapping and redirects are the foundation. We document every URL on your current site and map it to the corresponding URL on your new WordPress site. Every old URL gets a 301 redirect pointing to the right new location. Search engines follow these redirects and transfer ranking value to the new pages.
Meta data transfer preserves your optimization work. Page titles, meta descriptions, and other SEO settings are recreated on the WordPress side. If you're already using good SEO practices, we maintain them.
Search Console management ensures Google knows what's happening. We verify your WordPress site in Google Search Console, submit updated sitemaps, and monitor for crawl errors after launch. If issues emerge, we catch them quickly.
Monitoring and response continues post-launch. We track your key rankings and organic traffic in the weeks after migration. Some fluctuation is normal (search engines need time to process the change), but significant drops are investigated and addressed.
When migration is handled properly, most organizations see stable or improved search performance within a few weeks of launch.
Getting Your Team Ready for WordPress
WordPress is more powerful than Wix or Squarespace, which also means there's more to learn. But for content updates (the tasks most nonprofit staff actually do), it's quite approachable.
The editing experience in WordPress is intuitive for anyone who's used a word processor. The block editor lets you add and arrange content without touching code. Most staff can learn basic content editing in a 30-minute training session.
What requires more care: Plugin updates, security settings, and technical configuration should be handled by your hosting provider or developer (that's us, if you're a FatLab client). We handle the technical maintenance so your team can focus on content.
User permissions let you control who can do what. Your communications director might have full editing access, while a volunteer can only create draft blog posts that require approval. This flexibility helps organizations manage access appropriately.
Documentation helps with turnover. Nonprofits often experience staff transitions. We provide documentation specific to your site so new team members can get up to speed quickly, and ongoing support so questions get answered.
Why Professional Migration Matters for Nonprofits
We're obviously biased, but here's the honest case for professional help with nonprofit website migrations.
**You don't have time to figure this out. Your job is to advance your mission, not to learn WordPress migration techniques. The hours you'd spend troubleshooting import issues, configuring plugins, and fixing broken layouts are hours not spent on programs, fundraising, and impact.
The stakes are real. A botched donation form during a campaign is a real problem. Broken member logins frustrate constituents. SEO damage takes months to recover. These aren't just inconveniences. They affect your organization's effectiveness.
Nonprofit-specific expertise matters. Generic WordPress developers may not understand donation flow testing, CRM integration requirements, or the compliance considerations that affect mission-driven organizations. We've been doing this specifically for nonprofits and associations for over a decade.
The gap between "live" and "done right" is significant. Anyone can make a WordPress site technically functional. Making it performant, secure, accessible, properly integrated, and set up for long-term success requires experience and attention to detail.
Ongoing support completes the picture. Migration is a project, but your website is an ongoing operation. Having a partner who knows your site, understands your organization, and can help when questions arise is valuable beyond the initial migration. For more on what post-migration support should look like, see our guide to nonprofit website management.

Frequently Asked Questions
Will our recurring donors notice anything during migration?
It depends on your current setup. Suppose you're already using a standard payment gateway like Stripe or PayPal directly, and recurring donations continue seamlessly. In that case, we connect your new WordPress site to the same accounts, and charges continue to process. However, many Wix and Squarespace sites use the platform's built-in donation tools or embedded third-party systems that don't allow data export. In those cases, migrating to a proper WordPress donation system (like GiveWP with Stripe) may require asking recurring donors to re-enter their payment information. We help you communicate this transition and time it strategically, but it's important to understand upfront whether your current setup allows for seamless migration or requires a fresh start.
Can we migrate during an active fundraising campaign?
We strongly recommend against it. While we can technically migrate any time, the small risk of issues during transition isn't worth taking during your highest-stakes fundraising periods. Plan migration for a quieter time, like late winter or summer, when a brief focus on infrastructure won't compete with campaign priorities.
What happens to our email newsletter integration?
Email platform integrations (Mailchimp, Constant Contact, etc.) are reconfigured on the WordPress side. If your current forms feed subscribers to these platforms, we set up equivalent connections in WordPress. Your subscriber lists stay with your email provider and aren't affected by website migration.
How do we handle member login data?
This depends on your current setup. If an external AMS handles member authentication, we integrate WordPress with that same system, so members use their existing credentials. If members currently log in through Wix or Squarespace's native membership features, we typically need to import member data and have members set new passwords on the WordPress site.
Do we need to redesign our site when we migrate?
No. We can recreate your current design closely if you're happy with it. But many organizations use migration as an opportunity for at least a design refresh, since the site is being rebuilt anyway. The choice is yours.
How much does nonprofit website migration cost?
It varies based on site complexity, content volume, and required integrations. Simple brochureware sites are less expensive than complex membership portals with CRM integration. We provide detailed quotes after an initial consultation where we assess your specific needs. We also offer nonprofit pricing that recognizes budget constraints.
What if we have problems after launch?
FatLab provides ongoing WordPress hosting and support. After migration, your site is covered by our standard support, which includes maintenance, security, updates, and troubleshooting. You're not left to figure things out on your own post-launch.
