A method performed by a server device, may include receiving information about a customer order, associated with a particular service or product provider, from an ordering system; determining whether the customer order is eligible for a promotion based on the received information where the promotion includes a reward to a customer for placing the customer order; and requesting balance information associated with the customer order from a billing system, when the customer order is eligible for the promotion. The method may further include receiving a balance amount, associated with the customer order, from the billing system; determining whether the balance amount is less than a balance threshold; and sending a message to a fulfillment system to fulfill the promotion, when the balance amount is less than the balance threshold. |
