Enterprise B2B Procurement & 3-Way Matching Architecture

Corporate procurement often struggles with fragmented communication, unverified vendors, quote variance discrepancies, and manual invoice reconciliation that delays financial settlement.

• Engineered multi-tenant procurement workspaces with role-based approval hierarchies and granular spending limits.
• Built a structured RFQ and tender engine with line-item comparison matrices and sealed-bid integrity.
• Implemented automated 3-way matching reconciling Purchase Orders (PO), Goods Receipt Notes (GRN), and tax invoices.

• Enforced strict 4-tier KYC verification for vendor onboarding to ensure statutory commercial and tax compliance.
• Designed event-driven state transitions for order fulfillment to keep warehouse receiving and accounting synchronized in real-time.
• Structured immutable audit logs for every approval stage to ensure compliance and audit readiness.

The platform coordinates corporate sourcing across web portals and mobile clients, allowing buyers to publish specification-driven RFQs, evaluate vendor bids side-by-side, issue legally binding purchase orders, and release payments only upon verified GRN warehouse acceptance.

• Eliminated invoice-to-delivery discrepancies through automated 3-way matching.
• Accelerated quote evaluation cycles from weeks to transparent, real-time bid comparison.
• Complete visibility and governance over enterprise purchasing spend.
