Proposal for Sourav Das
OmniSync
Unified Catalog & Marketplace Sync System
One central catalog that keeps Shopify, Flipkart, Amazon, and Myntra in sync automatically, prepared by PrepifyX Technologies.
The Problem
Four channels, four sets of manual work
Today, listings are managed separately across the Shopify store, Flipkart, Amazon, and Myntra. Every new product, price change, or stock update has to be repeated by hand on each platform, which means duplicate work and inventory mismatches whenever one channel falls out of sync with the others.
The Solution
Upload once, sync everywhere
OmniSync gives you a single source of truth for your catalog. Add or update a product once, and it pushes automatically to every channel you sell on, no more re-entering the same listing four times.
Upload once

Timeline
20 days, start to handoff
Here’s how those 20 days break down, phase by phase.
Development

UAT & handoff
Note: Myntra’s exact pace depends on their API access being enabled by Sourav’s account manager, which is outside our control.
