Scheduled Exchange Rate Sync

Automate currency exchange rate updates on a cron schedule. Keep your pricing, invoicing, and financial data accurate with TrigRun.

Pull fresh exchange rates from a provider API every 2 hours during business days. Your backend updates pricing tables, invoice calculations, and reporting — automatically.

The problem

Your SaaS bills customers in multiple currencies, or your e-commerce store displays prices in local currencies. Stale exchange rates mean inaccurate pricing, incorrect invoices, and accounting discrepancies. You need rates refreshed frequently during business hours, but not necessarily overnight or on weekends.
