The challenge
Field & Flower ran on Magento. It sells weekly and fortnightly boxes that customers fill themselves, and a Christmas range sold once rather than on subscription. The Your Box catalog alone runs to 361 products.
Moving to Shopify Plus and Recharge meant carrying that model across intact: a box builder over the full range, a place for subscribers to manage their box, and protection against a subscriber starting a second box by accident. The store also had to keep taking orders through the cutover.
Solution
The box model, carried across intact.
We migrated the store from Magento to Shopify Plus, carried customers and order history across, and set up Recharge for subscriptions.
The box builder sits on Recharge’s bundle tools. Customers add items from category collections, see a running total with the subscription discount applied, and check out as a subscription or a one-off. Subscribers edit the same box in place. Recharge returns at most 250 products per collection, and the Christmas range held 315 in one collection, so we split it into 11 category collections, each under 250, and attached them all to the bundle.
Subscribers get a manage-your-box page showing the box contents, the next delivery date and a breakdown of subtotal, discount, shipping and total from Recharge’s upcoming charge. To stop duplicate subscriptions, we wrote a Shopify checkout validation Function that reads a flag on the customer record, kept in line with Recharge’s subscription events by a small relay on Vercel. That let us remove the forced sign-in step before checkout.
What we built
The build
- A Magento to Shopify Plus migration, with customers and order history carried across
- A box builder on Recharge’s bundle tools, with a running total and subscription discount
- The Christmas range split into 11 collections to fit Recharge’s 250-product limit
- A manage-your-box page and delivery dates in the account area
- A checkout Function that blocks duplicate subscriptions, so sign-in is no longer forced
- Fixes from the client’s UAT list: mobile layout, carousels, load-more and delivery dates
Technology: Shopify Plus, Recharge, Shopify Functions, Flare for delivery dates and Vercel for the Recharge webhook relay.
Impact
The result
We delivered the migration in three months, and the store launched in October 2026. James Mansfield, Field & Flower’s owner and CEO, reports that conversion to subscription has started to rise and that subscriber retention has improved since launch.
