I have a problem with the discount calculation in PayPal in combination with Magento. So far I just found other questions related to rounding problems or similar in PayPal and not comparable with my issue.
I use Magento CE 220.127.116.11
PayPal works great when there is no discount. It takes the
- net subtotal
- net shipping costs
- the tax
- grand total incl. tax
and everything is fine.
But when the user gets a %-discount, PayPal still calculates the tax based on the subtotal (without subtracting the discount). I hope the following image will clarify the issue.
- discount has to be excl. tax
- subtotal has to 'contain' the discount excl. tax
- tax has to be calculated after discount substraction
The grand total in PayPal fits, because the tax of the discount effect (2,11€) moved from subtotal to tax.
Tell PayPal to use the discount excl. tax und calculate the tax after the discount has been subtracted from the subtotal.
How do I manage that?
Thanks in advance!
Edit 1: PayPal Express is in Sandbox mode (if that is important to know)
Edit 2: Sry, with "PayPal caluclates", I mean the Service PayPal, the Magento extension or the whole payment process related to PayPal ;)
Here are my tax configuration settings:
