Tier change unavailable for your current billing currency. P

Error message

Tier change unavailable for your current billing currency. Please contact support — the target tier needs to be configured for your currency in Stripe before this change can go through.

What it means

HTTP 422 raised when modifying a subscription schedule fails because phases mix currencies - e.param == 'currency' or 'currency' appears in the message. Typical case: the active subscription was checked out in a non-USD currency (e.g. GBP) but the target tier's Stripe Price is USD-only, so Stripe rejects the schedule; the substring fallback also covers older error shapes where param is 'phases' or absent.

Solutions

  1. Contact support / ops to configure the target tier's price for the user's billing currency in Stripe and the flags
  2. Alternatively cancel and re-checkout in a currency the target tier supports (changes billing immediately)
  3. Operators: audit that every purchasable tier has prices in every currency you allow at checkout
Defensive patterns

Strategy: fallback

Validate before calling

const status = await api.getSubscriptionStatus();
if (status.currency && !tierSupportsCurrency(req.tier, status.currency)) warnUserBeforeSubmit();

Try / catch

try { await api.setSubscription(req); }
catch (e) {
  if (e.status === 422 && /billing currency/.test(e.detail)) showCurrencySupportNotice();
  else throw e;
}

Prevention

When it happens

Trigger: User whose active subscription bills in GBP/EUR requests a tier whose configured LD price exists only in USD (or vice versa); Stripe refuses to build a schedule whose phases change currency.

Common situations: Multi-currency rollout gaps: prices configured for some currencies only; users who originally checked out via a localized currency; a price flag pointing at the wrong currency's price ID.
