Feel free to use SpinOffice CRM Limited version for as long as you want until you have reached a storage of 50 items added manually. Mass import of contacts (Excel, Apple Contacts or social media) and incoming emails do not count as an item. You will get a notification when you’ve reached the storage limit and you will have to upgrade to SpinOffice Pro in order to add more items.
SpinOffice Pro offers up to 100,000 items of storage space per user, full email integration, 5 email accounts per user, daily backups, helpdesk support and more functionalities. The differences between the free Limited version and Pro can be found in the edition comparison.
