There are two types of Planiq Subscriptions; Free or Paid. Both subscriptions will give you access to the main modules of the service which includes Contacts, Organisations, Tasks, Orders/Quotes, Invoicing and Emails.
The difference between the two is that the Free subscription has set limits on each of the key modules, and the Paid subscription removes these limits. You can check the Pricing page for exactly what these limits are.
The second advantage of a Paid Subscription is the ability to send Mass Emails. This is really useful for sending a message to subsets of your Contacts.
The Paid Subscription can also be paid on a monthly or annual basis. Head over to our Pricing page to learn more.
