Understand QCMM Currency Display and Historical Currency Preservation

QCMM has a site/default currency used for current Plan pricing and checkout display. Changing that currency changes the currency code applied to current Plan prices; it does not perform exchange-rate conversion of the numeric Plan amounts.

Configure Current Currency

  1. Open QCMM Administrator Settings.
  2. Select the intended Default Currency and choose whether to show the currency indicator.
  3. Save, then review current Plan prices and a test Checkout before accepting transactions.

No Exchange-Rate Conversion

When the default currency changes, QCMM synchronizes current Plan currency codes. A price of 49.00 does not automatically become an exchange-rate-equivalent amount in the new currency. Review and intentionally edit Plan prices whenever changing the commercial currency.

Historical Currency Is Evidence

Existing billing, payment, Coupon, credit, invoice, and related historical records retain their saved currency context. QCMM uses those stored currencies when rendering or reconciling old transactions instead of rewriting history to the current site currency.

Payment Integrity

PayPal capture finalization compares the captured currency with the expected stored transaction currency. A mismatch is not silently accepted. This is why changing the site currency must not rewrite already-created historical payment evidence.

After a Currency Change

  • Review every currently sold Plan price.
  • Review Promotions/Coupons that have currency-sensitive rules.
  • Run a Sandbox checkout in the new currency.
  • Confirm old billing records still display their original currency.
