Hey,
Thanks for reaching out to us!
By default, I don’t believe WooCommerce supports multiple currencies for their cart. Doing a bit of research I did find this plugin https://wordpress.org/plugins/woocommerce-multilingual/. Is that what you’re referring to?
If your concern is whether or not our tickets plugin is compatible with an existing plugin you’re using, the best thing to do is to purchase and try it out. If it doesn’t work we do have a 3o day refund policy and we would be happy to refund your purchase.
Let me know if this helps.
Thanks!
