To be effective, and stay the proverbial one step ahead of competition, a sales team needs all the resources possible. Talk with any sales professional and you'll hear horror stories of deals gone bad and great opportunities missed. One of the most frustrating is closing the sale and then finding that the product or service can't be delivered per term because of supply, price or product changes. Linked to company databases by a PDA, sales people can verify availability, price and delivery status in real time. No broken promises, no lost business.
