1. An information processing system including a first service server that is configured to provide a first service, the first service server comprising:
communication circuitry configured to communicate with a user terminal of a user who does not have a first account of the first service and with a second service server that provides a second service different from the first service;
a processor; and
a memory storing instructions that, when executed by the processor, cause the processor of the first service server to:
receive a purchase request for a commodity or service from the user terminal which is not logged in with the first service,
send purchase request information based on the purchase request to the user terminal to cause the user terminal to display a purchase request screen,
receive first identification information of the user based on a first input field of the purchase request screen,
inquire, based on the identification information, of the second service server or a server associated with the second service server whether or not the user has a second account associated with the first identification information,
receive a response from the second service server indicating whether the user has the second account,
send display information to the user terminal to cause the user terminal to display a request to register the first account and to perform linking processing of the first account and the second account based on the user having the second account, and
link the first account and the second account based on receiving a confirmation from the user terminal to perform the linking processing,
wherein the processor is further configured to execute the instructions to cause the processor to determine whether the first identification information has been entered based on receiving completion information indicating an input cursor on the user terminal moved to a second input field after a last character was entered in the first input field.
