I am a B2B customer. Do I still need an OMS or will my ERP suffice?

Yes—B2B commerce still needs an OMS. ERPs were built to run the business (finance, inventory ledgers, procurement); OMS platforms are built to run customer-facing order flows in real time. In modern B2B—with self-service portals, EDI, marketplace channels and rising expectations for delivery accuracy—the ERP alone cannot promise, source or track orders at the pace customers now demand.

Why It Matters: B2B Buyers Now Expect B2C Speed

For B2B sellers, the buyer has changed. The same person who orders from Amazon at home now expects real-time availability, accurate promise dates and full order visibility from their industrial supplier or wholesaler. An ERP wasn't designed for that. Blue Yonder Order Management runs alongside the ERP, taking on the real-time customer-facing decisioning the ERP wasn't built to do.

3 Reasons B2B Needs an OMS Alongside the ERP

The OMS spans the full range of what modern B2B order flows require:

• Real-time promising: ERPs update inventory in batch cycles. B2B buyers now expect a live delivery date at quote or checkout—an OMS delivers that against live network availability.
• Complex order structures: Standing orders, blanket POs, forward-dated commitments and pre-season allocations are native to B2B and go beyond what a transactional ERP handles well.
• Multi-channel order capture: EDI, portal, sales rep, marketplace and direct API orders all funnel into one orchestration layer—the OMS is that layer.
