When you make a change to your subscription, the new fees are calculated based on:

1. The fraction of your current subscription time was used
2. The fraction of your new subscription will be used before your next billing date

For example, if you decided to try a $10/mo skill 15 days (half-way) into your monthly billing cycle, you will only be charged $5 (half the normal cost)

Similarly, if you cancel a $10/mo subscription half-way through your monthly billing cycle, a $5 credit will be applied to your next invoice.

When an addition is made to your (or your team’s) subscription plans by adding a new Skill or adding a new team member, a pro-rated charge is immediately billed.

When an item is removed, a credit is immediately applied to your upcoming invoice.
