Vendor relationships in 2025 aren’t just built on price and performance—they’re built on shared data. To operate efficiently in a global supply chain, glass and ceramic distributors are formalizing Vendor Data Sharing Agreements (VDSAs) that increase visibility, reduce surprises, and support collaborative planning.
Why Data Sharing Matters More Than Ever
Freight delays, labor shortages, and raw material volatility require real-time coordination.
Suppliers often sit on valuable lead time, batch, and material availability data.
Distributors can’t plan well if they don’t know what’s coming—or what’s changing.
What a Good VDSA Covers
1. Forecast Sharing
You provide rolling 30-, 60-, and 90-day demand forecasts to enable better vendor production planning.
2. Inventory Transparency
Vendors provide live or periodic inventory updates for raw materials and finished goods.
3. Production & Shipment Status
Updates on manufacturing stage, shipment preparation, ETAs, and delivery confirmations.
4. Exception Alerts
Vendors must flag delays, material changes, or labor shortages before the PO is impacted.
5. Digital Integration Method
Use EDI, API, or a shared portal to automate updates.
Benefits for Both Sides
Vendors reduce last-minute expediting costs
Distributors reduce safety stock and buffer inventory
Both parties align forecasts with fewer assumptions
Example: A refractories distributor built a VDSA with its primary insulative block supplier, enabling 2x/week automated material availability updates. This reduced their backorder rate by 28% in six months.
Final Word: Without structured data sharing, vendor relationships are opaque and reactive. A strong VDSA creates mutual transparency that scales.
