Orbi Marketplace

Overview

Built a dynamic multi-role marketplace where vendors upload inventory in bulk, dropshippers import products and set margins automatically, and independent sellers manage their own stores end-to-end. Payments to dropshippers are held for trust and released 7 days post-delivery.

Goals

• Automate product import and margin calculation for dropshippers
• Support bulk inventory uploads for vendors
• Enable independent sellers to manage listings and fulfillment
• Implement secure payment escrow with timed release
• Deliver a responsive mobile and web experience

Challenges

• Coordinating three distinct user roles with different workflows
• Ensuring data consistency between bulk uploads and storefront listings
• Implementing secure escrow-style payment flow with timed release
• Scaling image and catalog imports without impacting performance
• Providing seamless parity between Next.js web and React Native mobile apps

Solution

We architected a Django REST API with role-based permissions and webhooks for inventory sync. Bulk CSV and image imports were processed asynchronously via AWS SQS and Lambda. Dropshippers use a React/Next.js storefront to browse and import products; profit margins auto-calc based on vendor price ranges. Payments are held in an escrow table and released via scheduled Celery tasks 7 days after delivery confirmation. The React Native app mirrors core workflows for on-the-go management.

Results

• 70% reduction in manual product onboarding time
• 50% increase in vendor inventory uploads month-over-month
• 30% growth in dropshipper active listings within 3 months
• Zero payment disputes thanks to reliable escrow mechanism
• 4.8-star average rating on mobile app stores
