The dollars generated will come from traditional ad sales and a unique revenue model called Out of Room Revenue, which is generated from a "per inquiry" and an online mall. The "per inquiry" model is where the cost of commercial airtime is based on the amount of leads the media outlet can provide. The "online mall" model extends the advertising revenue generation to include future sales of product to the same client.
This unique and exclusive service has the potential to create a consistent inflow of revenue once a guest purchases from the online mall. Commissions are paid for products ordered through the Out of Room Revenue system or for orders originating from the web address or 800 numbers of the hotel's online mall.

Many luxury hotel companies are pursuing out-of-room revenue growth opportunities, including signature restaurants as well as spa and associated product innovations in specific properties. This has led to, amongts others, Gordon Ramsey at Claridges, Armani and Bulgari fashion house hotels and the association with other ‘cultural brands’ such as Bliss spa treatments. For an increasingly picky clientele the hotel experience is no longer just about room size, bed quality and location.

Ad Systems has also a per-inquiry revenue model that follows a hotel guest home to create an out-of-room revenue stream. Revenue generated from a "per-inquiry" and an online mall model can create a consistent inflow of revenue once a guest makes a purchase. The "out-of-room" model extends advertising revenue outside the hotel and into the travelers' homes and offices via a percentage of revenue share agreement. Commissions are paid for products ordered through their system or originating from web addresses or 800 numbers.
