Configuration templates can allow many Cisco Meraki devices to be deployed following a single base configuration. This makes it easier to roll out new sites/users and maintain consistency across each site's configuration. It is most useful in cases where a large number of sites exist that share a common network design. Such as a retail deployment with many stores, or a large number of home users with Z3s connecting to a corporate network over VPN.
Managing Multiple Networks with Configuration Templates - Cisco Meraki Documentation
Typically, new Dashboard networks are created so different deployments can have different configurations. However, there may be circumstances where it is ideal to deploy multiple networks with an identical or similar configuration. For example, an MSP may have a retail customer with a similar MX at each site. For these cases, the bulk network creation tool exists for quick and easy deployment of multiple networks at once, based on an existing network or template.

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
