I offer free installation for this extension
Convert your shop in multicurrency shop. Change currency for each product in admin. View different products currency at product,category,compare, manufacturer, special, featured,latest,special,bestseller pages.
Because lot of people write me about this , i must explain better:
With this extension you CAN NOT enter price for product in different currency in admin.
maybe some combination with this free extension ( which is not mine and i will not edit or update ) https://www.opencart.com/index.php?route=marketplace/extension/info&extension_id=23516
View products in different currencies in mini cart,cart and checkout page.
For more info visit demo page http://demo.plusmotiv.com/multicurrency
And admin http://demo.plusmotiv.com/multicurrency/admin admin/admin
Still user will recive invoice in one currency. My plan is to make update to work with invocies and maybe in admin part if there is interest in that. Fell free to comment
