ARI

Availability, Rates, Inventory. The three data feeds a channel manager keeps in sync across OTAs.

ARI (Availability, Rates, Inventory) describes the three feeds that hotels keep synchronized across direct and OTA channels: how many rooms are available, what rates apply to each rate plan, and how the inventory is allocated across channels. Channel managers automate the synchronization; ARI mismatches are the underlying cause of most overbookings.
