Are you planning to set up an e-commerce website, or sell goods and services globally? If so, then here’s a good idea: think about providing users with currency conversion.
Currency conversion tools let your customers have the price of an international currency transaction converted to their home currency when purchasing or checking out products online. It also allows visitors to see the exact amount their card or PayPal account will be charged, displayed in their local currency.
One advantage of showing currency conversion on your website is that it allows visitors to view and understand pricing in foreign countries in their own local currency, making it it easier for visitors to work out their costs and expenses.
If your site is built using WordPress, it’s really easy and simple to add currency conversion using a plugin to your WP website or blog, allowing your prospective customers to quickly understand the cost of your products.
