Purchase Preview

This functionality allows merchants to show the values that may affect the final amount of a purchase transaction.

When a buyer performs a purchase, the amount of it can be modified for several reasons:

Currency conversion (USD to local currency of the destination country)
Commissions to be paid by the customer
Taxes
etc.

For example, in Argentina there are different taxes that affect the final amount and, as a consequence, the merchant cannot show the real amount that will be charged until the purchase is completed.

As a solution, we created a tool that allows the merchant to preview the amount that the customer will be charged so that they can inform it prior to executing the purchase.

The following example shows the way suggested to the merchants to display the preview in Argentina.
