IN THE SPOTLIGHT
FUN & FUNCTION
Fun & Function was founded by pediatric therapist Aviva Weiss on a simple belief:
Operational drag on legacy Magento
As Fun & Function grew, so did the bottleneck. Every functionality, feature and even some content update, every operational change required a developer, creating friction for a non-technical team focused on serving children.
Inefficient backend and Magento performance issues added pressure. 80% of B2B buyers bypassed the website checkout entirely, increasing the operational load on Bayla Bernhardt, Fun & Function's website manager, and their support team.
Fun & Function asked for more autonomy without sacrificing the flexibility they relied on. Shopify Plus promised to deliver.
“We want to focus on children, not code”
Protect legacy data during migrations
The scale of the catalog, content, and business logic meant this would not be a simple platform switch. Protecting what already worked while improving other business operations required a structured approach.
That is why the Shopify team invited us to guide the migration and ensure the transition strengthened the business rather than disrupted it.
Mapping data and systems
Before any changes were made, we had to understand the Magento + Imprezian360 CRM setup Fun & Function’s business relied on. Their operations connected multiple systems, data sources, and teams, so the risk of doing critical damage was real.
“We map every field and flow not to drown the client in paperwork, but to ensure that when we finally flip the switch, nothing is left to chance.”
Desired Commerce Model
Legacy data audit outcome
✔ High volume, SEO-critical educational content
✔ Quote based purchasing and approval dependent order flows
✔ Cart-level shipping logic based on product size and delivery constraints
✔ Mandatory display of product regulations, geo-dependent warnings, and restrictions
✔ Dual navigation model, by product category and by diagnosis
✔ Extended operational control
The largest structural gap we discovered was the absence of real B2B experience.
Given the scale, the migration could not be treated as a single stream of work. So we structured it into parallel tracks, allowing progress while keeping the overall system stable, until…
Trap of content migration
“If top performing pages don’t migrate correctly, it means SEO impact, traffic loss, and ultimately revenue impact”
“Yep. That should have killed our timeline”
Shopify UX optimisation for B2C & B2B
After stabilizing the content layer, we moved to how customers would actually experience their new Shopify-powered store. Fun & Function serves parents, professionals, schools, and whole districts. So we had to account for all of them with:
Clear PDP structure with complex info
Frictionless login for legacy Magento users
Smarter registration with cleaner data
While much of the UX work focused on clarity and access, a separate layer addressed the main gap we discovered earlier: the need for a true B2B environment.
This shift meant institutions could finally purchase independently, reducing support tickets and enabling the Fun & Function team to scale without adding headcount.
Custom engineering: B2B quotes, order & shipping logic
The Fun & Function team quickly realised that their everyday operations like managing orders, content, and products were more straightforward. But while out-of-the-box Shopify features covered most of their needs, about 20% of their B2B operations required our custom solutions. To close the gap, we delivered:
B2B Quotes
Custom logic using Shopify draft orders to request quotes and generate PDFs for internal approval.
Cart-level Shipment Calculation
Integrated with C.H. Robinson to calculate shipping for dimensional items even before checkout.
Quick Order
SKU entry and CSV upload for bulk purchasing.
Invoice Links
Custom feature allowing users to download invoices directly from their Shopify account.
These adjustments ensured their store met not just standard ecommerce needs, but their specific operational realities.
Shopify ecosystem integrations
Each integration was treated as a separate workstream, not a toggle. Integrations are rarely truly plug and play, despite how many vendors position them. So we had to carefully align data mapping, edge cases, and system behavior to make the ecosystem operate as one.
Each integration was configured to work seamlessly within Fun & Function's workflows, reducing the need for custom development
“Searchanise was a major discovery. It covered 90% of functionality of the client’s previous enterprise solution for roughly a 10th of the cost.”
Team training and change management
From the start, the migration was treated as a change in how the business operates, not just a platform switch. The new system would never mirror the old one exactly, so we made sure that the Fun & Function team began working with their new tools as early as possible, building familiarity alongside the migration process.
“Clients should try their new tools, even in demo versions, to ensure the platform feels right before committing.”
“We have never seen an agency push us like this before!”
Launch on schedule with 100% data integrity
The beta version of Shopify-powered site went live on December 29th, 2025.
On January 21st, 2026, Fun & Function officially launched on Shopify Plus.
The successful migration improved their day-to-day reality in three clear ways:
Core Web Vitals in "Green"
Site speed was one of primary reasons for leaving Magento. Post-launch, the site earned Google's maximum ranking boost. Largest Contentful Paint dropped to an incredibly fast 1.78s, and Cumulative Layout Shift hit a perfect 0.
Keys Handed Back to the Team
The new admin is so intuitive that non-technical reps now manage daily updates without developer tickets, actively leveraging tools like Shopify Sidekick and 24/7 Plus support.
Manual Shipping Calculation Erased
Complex shipping rules, especially for oversized products that previously required tedious manual calculation, are now 100% automated.
Site speed was one of primary reasons for leaving Magento. Post-launch, the site earned Google's maximum ranking boost. Largest Contentful Paint dropped to an incredibly fast 1.78s, and Cumulative Layout Shift hit a perfect 0.
At the same time, it is important to acknowledge that replatforming 18 years of history means changing 18 years of habits.
While the B2C experience was an instant upgrade, adapting some legacy B2B workflows to Shopify's modern architecture is an ongoing learning curve.
Today, their new platform supports their mission rather than slowing it down, freeing the team to focus on what matters most: helping children learn, grow, and thrive.
