Does Multi-Currency change how points are calculated?
No. Multi-Currency only changes what customers see. Every calculation underneath — how many points a purchase earns, what a redemption costs, whether a customer qualifies for a tier — still runs on your store's base currency, exactly as before.
How is the converted value calculated?
Influence pulls Shopify Markets exchange rate data into the widget on the front end, then multiplies your store-currency value by that exchange rate to get the customer's local-currency value.
What happens to referrals when a customer is in a different market than the one they generated their code in?
The referral link and reward still work correctly — it takes the customer to the landing page for the market/domain it was generated in, and the flow triggers normally. What can be off is the display: if the customer has since switched markets, the widget may not show their referral reward converted into their current market's currency. However, the value will remain the same
What's the general fallback if Multi-Currency can't resolve a customer's currency?
If Multi-Currency is disabled, or a value can't be tied to a customer's market, Influence falls back to displaying your store's base currency.
How do refunds work with Multi-Currency?
The same way they always have — refunds are calculated based on your store's base-currency value, with no special multi-currency handling. There's no risk of a customer's points or monetary value changing due to exchange rate movement between the original order and the refund.
Can exchange rate movement affect what a customer sees?
Yes, in two ways worth knowing about:
Rate drift between when points were awarded and when they're viewed. The underlying point value never changes, but the displayed local-currency equivalent can shift if exchange rates move between when an action happened and when the customer next looks at their widget or a past email.
Tier progress display. Your progression percentage through a tier stays accurate (it's calculated against the base-currency threshold), but the local-currency amount shown as "remaining to next tier" is recalculated live each time, so it can look different from one visit to the next even though actual progress hasn't changed.
Can a customer gain or lose tier progress just because of a currency swing?
No. Tier membership and progress are driven by base-currency spend, not by the local-currency number displayed at any given moment.
