AppBind can accept payment in other currencies. We accept credit cards (Visa, MasterCard, etc.) internationally, and support direct bank payment where available.
Internally, everything is in US dollars (USD) and we issue US-based Visa virtual credit cards. Our virtual cards are accepted internationally. Because most services online accept US dollars paid by Visa, this works almost universally.
When you want to be paid out, we will pay you out in your local currency as well. We use a service Trolley.com for this.
