About this guide

Availability depends on where your business is established, its activities and the currencies or payment methods it needs. A provider operating internationally may not accept every merchant type or offer the same features in each country. Confirm eligibility directly before planning an integration. Review processing fees, settlement arrangements, refund handling, dispute processes and the information requested during onboarding. Ask how the service connects to your store and what technical responsibilities remain with you. eInternet Index does not process applications, assess a provider's financial position or guarantee account approval.
