Linking transaction with a service under one customer

Hi,
Assuming that I have separate services (Service A, Service B, and Service C) provided to one customer in different times, and I have one account called "Report Writing Fees" under "Cost of Goods Sold".
If I need to create an expense transaction under the category "Report Writing Fees", how to link this transaction with one specific service (ex. Service C) under that customer?
