Client requirement
Cercle.uk needed a high-end sustainable fashion rental marketplace — lenders listing luxury items for income, renters accessing those items at lower cost, with reliable payments, returns, clothing renewal, and multi-channel sales.
What we inherited, and exactly how each constraint was resolved.
Slow loads frustrated users, raised bounce rates, and cut engagement and sales.
We optimized product data handling and image caching, and moved heavy work to Sidekiq so the UI stays responsive.
Without store credits in the payment module, customers were stuck with cash, cards, or transfers — less flexible checkout and weaker loyalty after refunds.
We built a wallet / store-credits flow for refunds and cancellations, with encryption, secure tokenization, and regular security reviews.
Expanding reach meant users expected seamless shopping on social channels as well as the site.
We integrated Facebook e-commerce APIs so catalogues, inventory, and orders stay in sync between the site and Facebook.
Renewing worn rental clothes for resale needed a reliable partner for cleaning, repair, and logistics.
We connected Advanced Clothing Solutions (ACS) so used items ship from the renter, get renewed, and return to inventory.
Bugs left delivery and payment statuses wrong, causing mismanagement between business and users.
We fixed Solidus admin configuration and status code paths so delivery and payment states stay accurate.
Tight deadlines risked delayed launches and quality cuts.
We ran agile sprints with smaller iterations and regular checkpoints to protect quality and ship on time.
Powerful search with filters, caching, and indexing so renters find the right item quickly.
Push notifications near rental end so customers return items and route them through ACS renewal.
Admin tools for listings, users, cancel/refund policies, taxation, and shipping.
Clothing renewal pipeline with Advanced Clothing Solutions after each rental cycle.
One system consolidating orders across sales channels.
Checkout calculates delivery from address and basket size, with postal-code and city suggestions as the user types.
Faster performance cut bounce rates and supported higher sales.
Ordering and returning used products became a smoother, lower-friction flow.
Better filtering helped users match preferences and decide faster.
Admin tools for discount codes and promotions made campaign ops more efficient.
Stripe plus store credits improved refund UX and kept spend on-platform.
