ShopFlow — Multi-Vendor E-Commerce Marketplace
A multi-vendor marketplace platform with vendor onboarding, dynamic commission structures, real-time inventory sync, and integrated Stripe Connect payments.
Project Overview
ShopFlow is a multi-vendor e-commerce marketplace built for a startup that connects local artisans and specialty retailers with consumers. The platform handles vendor onboarding with identity verification, dynamic commission structures per category, real-time inventory sync across vendor POS systems, and automated Stripe Connect payouts. The React storefront delivers a unified shopping experience across 420+ vendors, while the Laravel backend manages complex order splitting, shipping calculations, and dispute resolution workflows.

Repeat Purchase Rate
The startup had a basic single-vendor Shopify store and wanted to transform into a marketplace. The existing setup could not handle multiple vendors, split payments, or per-vendor inventory management.
Single-vendor Shopify store with no multi-vendor capability
Manual bank transfers to vendors — payments took 2-3 weeks and frequently had errors
No way to manage per-vendor inventory leading to overselling and cancellations
Customer support overwhelmed with order issues spanning multiple vendors per order
We designed a marketplace from the ground up with Stripe Connect at its core for automated payment splitting. Each vendor gets a self-service dashboard for inventory, orders, and performance analytics.
Built a vendor onboarding flow with identity verification and automated Stripe Connect account creation
Implemented dynamic commission structures — configurable per category, vendor tier, and promotion
Created real-time inventory sync with vendor POS systems via API and CSV import fallback
Designed smart order splitting that groups items by vendor with per-vendor shipping calculation
ShopFlow transformed a single Shopify store into a thriving marketplace with 420+ vendors. Payment accuracy reached 99.9% with automated splits, and the repeat purchase rate of 2.8x indicates strong consumer loyalty.
Onboarded 420+ vendors with automated KYC and Stripe Connect provisioning
Processed $3.6M in GMV with 99.9% payment accuracy and automated vendor payouts
Overselling incidents reduced from 8% to 0.3% through real-time inventory sync
Average vendor payout time reduced from 2-3 weeks to 2 business days
Technologies Used
“We went from a single Shopify store to a 420-vendor marketplace in under four months. ShopFlow handles the complexity of split payments, per-vendor shipping, and inventory — things that would have taken us years to build ourselves.”
