Why a dollar-priced download has a changing INR amount
Follow the source price, exchange-rate observation and final invoice as separate records.
Why a dollar-priced download has a changing INR amount
A seller may want to keep a digital product at a fixed dollar price while offering convenient local-currency checkout. That means the USD price is the source and the INR amount is a converted catalog price, rather than two unrelated promises.
For Combine Invoices, the source is US$12.99 for the one-time plan. The INR amount can change as the catalog's validated exchange-rate observations change.
Start with the source currency
A source price tells the converter which amount should remain fixed. If the seller instead fixes an INR amount and converts it into dollars, the displayed USD amount can move. Those are different pricing choices even if they happen to match today.
A named source currency makes the intended behaviour easier to audit.
Understand the converted price
The catalog creates normal Paymenter prices for supported currencies. The selected checkout and invoice use that actual currency amount. Required options and applicable taxes still need to be reviewed before payment.
Manually maintained target prices are preserved. This prevents an automatic refresh from silently replacing a seller's explicit local-currency price.
Keep issued invoices separate
An exchange-rate update does not rewrite an invoice that has already been issued. Likewise, changing the storefront selector does not convert existing account credit or change an older service's agreed billing price.
Use the currency and total printed on your own invoice when making a payment or contacting support.
Is the rate guaranteed by PayPal?
No. Catalog conversion is separate from payer or settlement conversion at a payment provider. This store currently uses validated reference rates; its PayPal FX quote check requires an account contract before that optional source can be activated.
Read the currency guide and the extension listing for the current plan. Compare the final checkout amount rather than an old screenshot of its INR price.
