OMS (Order Management System)
Quick answer
The system centralizing orders from every channel (EDI, online, phone, field agent) and orchestrating execution.
Key takeaways
- Multi-channel capture: EDI, REST API, marketplace, webhook, manual
- Stock allocation: dynamic warehouse reservation, FEFO, backorder allocation
- Credit & fraud check: customer limits, automatic blocking
- Splitting: a 12-item order split across 3 warehouses + drop-ship
- Shipment orchestration: handoff to WMS, TMS, 3PL, fulfillment
Definition
OMS (Order Management System) is the platform that receives, validates, allocates and orchestrates every order regardless of origin channel: retailer EDI, online store, marketplace (eMAG, Amazon), call center, field agent (SFA), B2B portal.
Why it differs from ERP
ERP handles the fiscal order (invoice, accounting stock). OMS handles the operational cycle (real-time stock allocation, multi-warehouse split, pallet regrouping, prioritization). An ERP without OMS = bottleneck above 50 multi-channel orders per day.
Key functions
- Multi-channel capture: EDI, REST API, marketplace, webhook, manual
- Stock allocation: dynamic warehouse reservation, FEFO, backorder allocation
- Credit & fraud check: customer limits, automatic blocking
- Splitting: a 12-item order split across 3 warehouses + drop-ship
- Shipment orchestration: handoff to WMS, TMS, 3PL, fulfillment
- Status tracking: live dashboard from received → delivered → invoiced
OMS in CRMconnect
CRMconnect OMS works Standalone (replacing order management) or as Smart Layer (on top of SAP B1, Charisma, Senior, WinMentor - bi-directional sync).
Real-world example
A D2C brand handling 12,000 orders/month (eMAG 60%, Amazon 15%, own site 25%) runs back-office with 2 people thanks to OMS auto-allocation and routing into 3PL + supplier drop-ship.

Frequently asked
Does OMS replace ERP?+
No. OMS handles operations, ERP remains the financial source of truth. OMS syncs bi-directionally with ERP.
Do I need OMS if I sell only through my own site?+
Below 30 orders/day, the online store + a spreadsheet can suffice. Above 50/day or with 2+ channels, OMS becomes immediate ROI.
