Your free trial account lasts for 14 days and includes all the same features you would see in a real account. You can enter fake data and try out the configurations module.
Integrations with external sites should not be tested during your trial; for example, setting up your Petfinder auto-upload would overwrite any animals in your existing Petfinder account. It is also not possible to test out the Maddie's Pet Assistant integration without a real account.
Keep in mind that anything you do in a trial account does not transfer over to a real account when you officially sign up with Shelterluv.
If you need an extension on your trial, just let us know before it ends, or you can create a new trial account after your current one expires.
