| proration cost = (period end - API request time) / (period end - period start) * quantity * plan price |
@bocharsky-bw it is the actual time, like date() now() or wathever. As of Stirpe uses unix time you should be able to use it to.
I would use this for a yearly subscription: quantity * plan_price * 12 * (period end - Api request time) / (period end - period start)
You compute a ratio of the time left / total time, then multiply that by the annual cost.
