Challenge & Solution

What we solved

Challenge: Existing Bangladeshi marketplaces force customers to place separate orders per vendor (separate cart, separate shipping, separate checkout) — leading to high cart abandonment and weak vendor economics. Multi-vendor payout infrastructure is also fragile and slow. Solution: SGT Cart uses a unified single-cart checkout across all vendors with Stripe Connect routing payments to each vendor in real time. Vendors get a dedicated dashboard (Vue.js portal) with KYC onboarding, inventory + order management, payout history, and analytics. Buyers get one cart, one checkout, one shipment-tracking view across multiple vendors.

Platform Fee

SGT Cart aims to onboard 20+ local Bangladeshi artisans and brands at launch, growing to 100+ vendors and 5,000+ SKUs within year one. Unified single-cart checkout across vendors removes the biggest pain point in current Bangladeshi marketplaces, where customers must place separate orders per vendor.
