This addon works by running whenever a client page is displayed and uses the visitors IP to automatically switch them to the relevant currency for their location. If their currency is not set up in WHMCS, it will fall back to the default. Location is determined using the geoplugin.com XML API. Simply register your WHMCS installation IP with them and you're good to go.
No special server configuration needed. Requires PHP 5.6+ and WHMCS 7.0 or newer. You will need to whitelist your WHMCS installation IP at geoplugin.com.
It is $6.00 CAD monthly (or $60 CAD annually - essentially getting 12 months for the price of 10) with free support & updates for as long as your service is Active.
Download the zip file from our client area and follow the instructions in the INSTALL.txt file included.
