Prepaid Utility Bill Discussion

Need help with my Accounting question – I’m studying for my class. an invoice dated 3/14 is for internet utility services. The services are dated from 3/14-4/14. How would you record the journal entry? Would you record the march service by debiting utility expense and then in the same transaction, debit prepaid expense: utilities for the April service? I always thought prepaid was for a large purchase paid for up front that had to be expenses monthly.
