Rezdy comes with a long list of resource Types to cater to most business types. There are 2 common purposes for setting the correct resource Type when it comes to resource creation:
Using Resource Types for tracking and reporting purposes
For example running a Sales - Products report, which allows you to see exactly which Resources are being used.
Using Resource Types to manage availability
By using the same Type setting, you're able to increase availability if a particular product is running low on inventory. For example; assigning another Guide type resource to a session to increase available spots.
