The agreement will give IHG a access to Hotelzon's corporate and travel agency customers, bypassing more traditional electronic booking tools and allowing Hotelzon direct access into its inventory.
It is claimed the deal will bring cost per booking savings to IHG, including electronic invoicing, prepayments and paperless booking.
Hotelzon chief executive Jani Kaskinen said: "The brand’s reservations system will see an immediate benefit from the partnership and will save hotels significant money by cutting out the middle man. This deal is testament to the recognition of the status Hotelzon has developed within the industry."
