Do you plan to set up an e-commerce site using WordPress, or sell goods worldwide? If so, you should probably consider providing users with a currency conversion service.
Currency conversion allows your visitors to have the price of a foreign currency transaction translated to their home currency at the point of sale. It also allows your visitors and customers to see the exact amount their card or PayPal account will be charged, displayed in their own home currency.
The obvious benefit of adding currency conversion is that it allows your customers to see and understand prices in foreign countries in their own home currency, and makes it easier for purchasers to work out their costs and expenses.
If your site is built using WordPress, it’s quite easy and simple to add currency conversion using a plugin to WordPress, allowing your site visitors to quickly work out the cost of your goods.
