The quotas are defined by the group the customer was assigned to.
A group assignment can be made by admin, or by buying a certain price plan.
The quota values are applied on a monthly basis.
Let’s say the Free Plan is having the following quotas: 10 notes, 10 requests, 10 snippets and a limit for attachments of 10 Mb.
That means a user can send 10 notes in the current month, each of them having an attachment of a maximum size of 10 Mb. When the next month starts he will have these quotas available again.
For bigger quotas, a different plan can be bought and a subscription will be set.
