Exchange Rates API

Official Exchange Rates for Tax & Customs

In most countries the use of exchange rates for foreign currency invoices and indirect tax return calculations is regulated by the national VAT and GST legislations. You must use approved rates, otherwise you risk VAT/GST underpayment and the associated interest and penalties.

For businesses operating in multiple countries, keeping up with these requirements can be challenging. We provide a simple solution that can easily be integrated with your system to comply with the local exchange rate conversion rules in all supported countries.
