Should you tell a client if you used a template or a shortcut to finish early?

One thing about freelancing is that freelancers are not oblige to say the process of completing their tasks. They are only to pay you for the speed and the outcomes of the tasks. If talking about your templates won't add anything to the clients, you may not need to disclose the way you did the task to the clients. Have you been in this situation before? How did you navigate through it? Share it below in the comment section.
