OMS (Order Management System)

In one line

Orchestrates fulfilment after checkout — order routing, inventory sourcing, delivery promising, and tracking.

Fuller explanation

An OMS connects the online order to real-world fulfilment: routing orders, sourcing inventory across stores/warehouses, enabling ship-from-store and BOPIS, and promising delivery dates. Fluent Commerce is a MACH-certified OMS. It's a frequent expansion opportunity because fulfilment pain is visible and costly.

Interview phrase

"The OMS is where omnichannel promises meet physical reality — and where margin leaks if it's weak."
