Every Subscription to AccountingSuite™ comes with a Test Company (or Sandbox as it is sometimes called) free of charge. You can copy over the data from your live company and use the test company to:
Train new users
Try out new features
Enter data to see the results before entering it in your live company
None of these actions will change anything in your live account so you have the freedom to train, try and test without having to worry about making a mistake in your live account!
