Finlyzer — FX Loss & Margin Insights for WooCommerce

Finlyzer gives WooCommerce merchants clear, honest visibility into how much revenue is lost to foreign exchange fees and payment processor markups on international sales. It is 100% Free with no hidden fees, no subscriptions, and no credit card required. 🔒 100% Local by Default — Zero Surveillance Telemetry Merchants trust Finlyzer because of its privacy architecture:

• Runs 100% Locally on Your Store Database by Default: All currency loss math, gateway fee spread analysis, and multi-currency ledgers are calculated entirely on your own server. Zero external network calls are made out-of-the-box.
• No Sensitive Information Needed: Finlyzer never requests, accesses, stores, logs, or transmits sensitive customer or financial data.
• Zero Personally Identifiable Information (PII): Customer names, email addresses, phone numbers, billing/shipping physical addresses, IP addresses, credit card numbers, and individual order IDs are never collected, saved, or sent anywhere.
• Zero Checkout Impact: Runs purely in the WordPress admin dashboard for completed orders. Your checkout flow, storefront speed, and buyer experience remain 100% untouched.

Why Every International WooCommerce Store Needs Finlyzer When international shoppers purchase from your store in foreign currencies (EUR, GBP, CAD, AUD, JPY, etc.), payment processors like PayPal, Stripe, Klarna, WooPayments, Mollie, and Adyen convert those funds into your payout currency. Instead of using true interbank market exchange rates, payment gateways charge hidden conversion spreads—typically pocketing 1.5% to 4.2% or more on every cross-border order. On top of gateway spreads, foreign exchange rate fluctuations during settlement create additional currency loss. Finlyzer inspects your store sales data and reveals the exact numbers:

• Total Currency Loss: View exact currency loss across the last 30, 60, or 90 days.
• Effective Fee Rate: Reveal true conversion spreads per processor (Stripe, PayPal, Klarna, etc.).
• Loss Distribution by Currency: Visual breakdown showing which currencies erode margins most.
• Annual Run-Rate Exposure: Projected yearly loss if gateway markup is left unaddressed.
• AI Sentinel Insights: Real-time risk audit powered by Google Gemini Flash AI providing prioritized, actionable recommendations to protect merchant profits.

Key Features for WooCommerce Merchants

• Payment Gateway Fee Comparison: Compares cross-border transaction volume and conversion fee impact across Stripe, PayPal, Klarna, WooPayments, and more.
• Multi-Currency Revenue Ledger: Detailed breakdown of transaction volume, fee share, and currency loss per foreign currency.
• Products Breakdown: Line-by-line attribution of international revenue and conversion fees per product, with fast processor filtering.
• Exchange Rate Movement & Market Timing: Directly queries European Central Bank reference exchange rates via the public Frankfurter API (https://api.frankfurter.dev) using WordPress HTTP API (wp_remote_get) to evaluate settlement timing loss between order placement and processor payout.
• High-Performance Order Storage (HPOS): Built-in native support for WooCommerce custom order tables (wc_orders) and traditional post meta.
• Lightweight & Fast: Pure server-to-server analytics engine with cached responses and asynchronous telemetry.
• 100% Free: Full access to all financial analytics with zero paywalls.
