We support the ability to upgrade or downgrade your subscription anytime. We use the proration method for billing. Below is an example of how proration works.
Walter White signed up for a Basic plan (€99 monthly) in January.
- Subscription Price: €99,00/month
- First Bill Date: 1 January 2013
- Next Bill Date: 1 February 2013
- Current Billing Period: 1 January 2013 – 31 January 2013
Walter decided to upgrade his subscription on 15 January 2013 to a Team plan that is priced at €199,00. When he does that a new transaction is created for €51,61. How was that calculated?
We take the new subscription price of €199,00 and subtract the price associated with the old subscription (€99,00). We divide the difference by the number of days in the billing period, which is 31. We then take that amount, which is €3,225 and multiply it by the number of days left in the billing period which is 16.
Formula:(€199,00 - €99,00) * 16/31 = €51,61
