I am trying to implement seat based pricing but the documentation is very vague on what happens when plans are changed and how I can handle it.
For reference these are the docs I am following: https://developer.paypal.com/docs/api/subscriptions/v1/
Let me give you an example. Lets say I have this pricing:
- 1-10 seats $5 each per month
- 11+ seats $3 each per month
To mimic this in PayPal I create 2 quantity based subscription plans. One with a quantity price of $5, the other for $3. Both plans are on the same product and have term set to monthly.
There are a few situations I am unsure how to handle and cannot find this information in the docs. They are as follows:
1) User signs up for 1 seat on the 1st June. On the 15th June they decide to change to 5 seats. The docs say this will be adjusted in the "next billing cycle" but I am unclear what that means. Their next billing cycle is in 15 days so does that mean they get access to 4 seats for free that month? What I would want to happen is the difference is calculated. The user has paid $5 so far and is halfway through the month so half a month cost is $2.50. The new subscription price is $25. So the remainder of the month would cost $12.50. So the difference to pay is $10 to cover them to the end of the month with the additional seats until they will then be billed $25 for a full month. Is this in anyway possible?
2) User signs ups for 5 seats. They then upgrade to 20 seats halfway through the month which moves them onto a different plan to get discounted pricing. How does situation 1 play out again in this regard when changing plans? How are the differences calculated and billed?
Many thanks
