How Co-Terms Work for Additional Subscription Orders?

The formulas are

• Settlement of the existing plan = Total amount of the existing plan – Total amount of the existing plan/30 days* (how many) days you used
• Amount for additional licenses = Total amount of the new plan – Settlement of the existing plan

To make the math easier, we will just use $10 per month and $90 per year as an example.

      For monthly subscription,

• On Nov 3^rd 2020, you purchase 10 licenses of PhantomPDF Business Monthly. Total amount of the existing plan is $100. Your monthly billing date is Nov 3^rd
• On Nov 10^th 2020, you purchase 3 more licenses.
• On Nov 10^th 2020, your new plan is 13 licenses of PhantomPDF Business Monthly, total amount of this new plan is $130. Your monthly billing date changes to Nov 10^th
• For the existing plan, settlement of the existing plan is $100- ($100/30 days*7 days used) = $76.67.
• For the new plan, the amount for 3 more licenses you should pay is $130 - $76.67=$53.33.

     For yearly subscription，

• On Nov 3^rd 2020, you purchase 10 licenses of PhantomPDF Business Yearly. Total amount of the existing plan is $900. Your yearly billing date is Nov 3^rd
• On Nov 10^th 2020, you purchased 3 more licenses.
• On Nov 10^th 2020, your new plan is 13 licenses of PhantomPDF Business Yearly. Total amount of the new plan is $1,170. Your yearly billing date changes to Nov 10^th
• For the existing plan, settlement of the existing plan is $900 – ($900/365 days*7 days used) = $882.74.
• For the new plan, the amount for 3 more licenses you should pay is $1,170 - $882.74=$287.26.

Note: The actual payment amount will fluctuate as it will be automatically calculated by stripe according to the actual supplement or exchange rate change.
