Project Overview
This Enterprise SaaS platform automates B2B transaction flows, tracking order lifecycles from submission to final delivery and mapping billing details synchronously.
The Problem
Staff spent 15+ hours weekly manual-matching inventory records with client bank deposits, leading to errors and delays in distributor fulfillment cycles.
The Solution
Designed and engineered an automated order fulfillment ledger with real-time stock deductions and client invoice generation pipelines.
System Architecture
Decoupled React/Next.js dashboard communicating with a transactional Node.js database ledger, utilizing custom index maps to keep query returns under 150ms.
