Systems and methods to facilitate online transactions

1. A computer implemented method, comprising:

receiving, by a computing device, a request for a purchase from a merchant computer system;

providing, by the computing device, an interface to the merchant computer system, wherein the computing device transmits the interface to the merchant computer system after receiving the request from the merchant computer system;

transmitting, by the computing device, at least one option via the interface that is selectable by the merchant computer system;

receiving, by the computing device using the interface, a first input based on the option from the merchant computer system via the interface;

determining, by the computing device, a price of the purchase, wherein the price is based on the first input from the merchant computer system;

transmitting, by the computing device, the price to the customer computing device;

receiving, by the computing device, a purchase from the customer computing device in response to the transmission of the price; and

charging, by the computing device, a customer account based on the price in response to the purchase,

wherein the price is a total price that is based on a first price and a portion of service charges associated with at least one message, the portion being specified by the input received via the interface, the input specifies the portion as a percentage of the service charges associated with the at least one message.

2. The method of claim 1 , wherein the interface comprises a web based user interface.

3. The method of claim 1 , wherein the interface comprises an application programming interface.

4. The method of claim 1 , further comprising:

receiving, in the computing device, an input from the merchant using the interface to change the percentage for subsequent purchases.

5. The method of claim 1 , wherein the first input specifies the portion as a fixed amount.

6. The method of claim 5 , further comprising:

receiving, in the computing device, a second input from the merchant using the interface to change the fixed amount for purchases that occur after the second input.

7. The method of claim 1 , wherein the input is for first items offered by the merchant; and the method further comprises:

receiving, in the computing device, a second input from the merchant using the interface for second items offered by the merchant; and

determining, by the computing device, a price of a second purchase based on a second input from the merchant computer system;

transmitting, by the computing device, the price of the second purchase to the customer computing device;

receiving, by the computing device, a purchase from the customer computing device in response to the transmission of the price of the second purchase; and

charging, by the computing device, a customer account based on the price of the second purchase in response to the second purchase.

8. The method of claim 7 , wherein each purchase is for one of: products and services.

9. The method of claim 7 , wherein each purchase is for virtual objects.

10. The method of claim 9 , wherein each purchase is for one of points, virtual currency, and credits.

11. The method of claim 7 , wherein the input includes the first price.

12. The method of claim 11 , wherein the input includes an identification of an item sold in the first purchase.

13. The method of claim 1 , further comprising:

presenting, by the computing apparatus, a web page to confirm payment to be made via one or more premium messages;

in response to a confirmation via the web page, transmitting a non-premium message to a mobile phone of the first customer to confirm payment to be made via the one or more premium messages; and

after receiving a response to the non-premium message, transmitting, by the computing apparatus, the one or more premium messages to the mobile phone of the customer.

14. The method of claim 13 , wherein the web page identifies to the customer that the merchant offers to pay for the portion of service charges associated with the one or more premium messages.

15. The method of claim 13 , wherein the non-premium message indicates that the merchant offers to pay for the portion of service charges associated with the one or more premium messages.

16. A non-transitory computer storage medium storing instructions, the instructions causing a computing device to perform a method, the method comprising:

receiving, by a computing device, a request for a purchase from a merchant computer system;

providing, by the computing device, an interface to the merchant computer system, wherein the computing device transmits the interface to the merchant computer system after receiving the request from the merchant computer system;

transmitting, by the computing device, at least one option via the interface that is selectable by the merchant computer system;

receiving, by the computing device using the interface, a first input based on the option from the merchant computer system via the interface;

determining, by the computing device, a price of the purchase, wherein the price is based on the first input from the merchant computer system;

transmitting, by the computing device, the price to the customer computing device;

receiving, by the computing device, a purchase from the customer computing device in response to the transmission of the price; and

charging, by the computing device, a customer account based on the price in response to the purchase,

wherein the price is a total price that is based on a first price and a portion of service charges associated with at least one message, the portion being specified by the input received via the interface, the input specifies the portion as a percentage of the service charges associated with the at least one message.
