💱 Automatic Exchange Rates

Stop manually updating exchange rates. WPC Multi Currency connects to leading rate providers and keeps your prices accurate around the clock.

Supported Providers

• ExchangeRate-API — free tier available, no API key required
• Fixer.io — trusted by 170,000+ companies worldwide
• CurrencyFreaks — real-time and historical rates

Scheduled Updates
Configure automatic rate updates on your preferred schedule: every hour, twice daily, daily, or weekly. Rates are fetched in the background via WP-Cron — your visitors never see a delay.

Manual Override
Need full control? Set a fixed exchange rate for any currency and the auto-updater will leave it untouched. Mix and match: use auto rates for USD/EUR and manual rates for niche currencies.

🧠 Smart Psychological Pricing

Raw currency conversions often produce ugly numbers like $23.4712 or ₫587,342. Smart rounding transforms these into prices that feel natural and drive conversions.

Available Rounding Modes

• Nearest 1 / 10 / 100 / 1000 — standard mathematical rounding
• Charm .99 — the classic $29.99 ending that signals a deal
• Charm .95 — a softer alternative preferred in luxury markets
• End in 9 — rounds to the nearest integer ending in 9 (e.g., $229)
• Charm .000 — rounds to the nearest thousand, perfect for VND, IDR, KRW

Each currency can have its own rounding rule. So you might use Charm .99 for USD, Charm .95 for EUR, and Charm .000 for VND — all from the same base price.

🏷️ Dual Price Display

Build customer trust by showing both the converted price and the original store price side by side.

When enabled, a subtle secondary price appears below the converted price on product pages:

₫730,000 (≈ $29.99)

This transparency reassures international shoppers that the conversion is fair, reducing bounce rates and support tickets. The original price inherits the base currency's formatting (symbol position, decimal separator, thousands separator) automatically.

🔄 Flexible Switcher Components

Give customers multiple ways to change their currency, each customizable to match your theme.

Menu Switcher
Append a currency switcher to any WordPress navigation menu. Choose between a compact dropdown or inline buttons. Configure which menus to target — primary, footer, or both.

Product Page Switcher
Place a switcher directly on the single product page at one of 7 positions: before/after the title, before/after the price, before/after the add-to-cart button, or after the product meta. Choose dropdown or button style independently.

Floating Switcher
A fixed-position FAB (Floating Action Button) that stays visible as customers scroll. Pick from 6 positions: top-left, middle-left, bottom-left, top-right, middle-right, or bottom-right. The panel opens with a smooth scale animation and lists all currencies with flags, codes, symbols, and checkmarks.

Widget & Shortcode
Use [wpcmc_switcher] or [wpcmc_switcher style="buttons"] anywhere. A dedicated WooCommerce Widget is also available for sidebar placement.

Custom Flags
Upload custom flag images via the WordPress Media Library, or fall back to emoji flags. Flags appear consistently across all switcher types — menu, product page, floating, and shortcode.

💳 Currency-Specific Rules

Control which payment gateways and shipping methods are available for each currency.

Payment Gateway per Currency
Restrict payment gateways based on the selected currency at checkout. For example, allow PayPal only for USD and EUR, while enabling local bank transfer for VND. Leave a currency unconfigured to allow all gateways.

Shipping Method per Currency
Restrict shipping methods per currency. The plugin scans all WooCommerce Shipping Zones (including "Rest of the World") and lets you pick which methods are available for each currency using a searchable multi-select powered by SelectWoo.

📧 Order Email Currency

Order confirmation emails automatically display prices in the currency the customer selected at checkout. No extra configuration needed — the plugin reads the saved order meta (_wpcmc_currency, _wpcmc_rate) and temporarily overrides WooCommerce's currency formatting during email rendering.

This ensures your customers see familiar numbers in their inbox, not confusing base-currency amounts.

🌍 GeoIP Auto-Detection

Automatically detect your visitor's country using IP geolocation and switch to the appropriate currency before they even interact with your store. Supports MaxMind GeoLite2 and WooCommerce's built-in GeoIP database.

Visitors can always override the auto-detected currency using any switcher component. Their choice is saved in a cookie for 30 days.

⚡ Enterprise Caching Compatibility

Multi-currency and page caching are notoriously difficult to combine. WPC Multi Currency solves this with intelligent, per-plugin cache integration.

• WP Super Cache — accepted cookies list
• SG Optimizer — Vary header integration
• Comet Cache / ZenCache — WooCommerce cookie consideration
