If you have more than one Mac, or you have purchased Easy Books for iOS, you may want to transfer your data between your devices. There are two main methods:
Backup and Restore - You backup your data on one device, transfer the file and restore it on the other(s).
Online Syncing - Every change you make is sent and stored online. When you use Easy Books on another device, it updates itself automatically.
If you manually backup and restore to a different device, it will warn you if you are about to overwrite your existing data with the data contained in the backup. You are responsible for keeping track of which device holds the "master" copy if you want to make changes on different devices.
If you choose the Online Sync service, you will need to register and pay for an account. You can try the service out for two weeks to see if you like it. You can also share access to your business with other users, giving read-only or full access.
