Challenge

Outgrowing a single-brand storefront

The client wanted to launch a multi-vendor marketplace but their existing monolith could not handle shared catalogs, split payouts, or traffic spikes during promotions. Every new vendor required manual setup by engineering.

Vendor onboarding and catalog management were fully manual
Checkout reliability dropped during peak traffic events
Finance had no visibility into commissions or payout schedules

Solution

Headless commerce architecture for marketplace scale

We built a headless storefront with dedicated vendor dashboards, automated catalog synchronization, a resilient checkout flow, and payout infrastructure that finance teams could audit independently.

Vendor self-service for product listings, pricing rules, and fulfillment
Redis-backed cart and inventory locks during traffic peaks
Automated payout scheduling with dispute handling hooks
Search and merchandising tools for the internal growth team

Results

Growth without proportional ops headcount

Vendor onboarding shrank from weeks to days. The platform handled its first holiday peak without a single emergency escalation.

Vendor go-live reduced from 2 weeks to 3 days
Checkout conversion lifted 19% after the performance pass
Vendor count tripled without adding operations staff

Testimonial

Client perspective

“They treated marketplace edge cases like split carts, partial refunds, and vendor SLAs as first-class features. Not afterthoughts.”
