What is the minimum amount required to top up an account?

Upon opening an account (after verification with the provision of IBAN or approval of the project), a one-time account opening fee is charged.
Maintenance of a personal account is free of charge. However, there is a monthly maintenance fee for a business account and fixed costs for additional services.
The entire list can be found on the Pricing page.
Knowing your location and business model, you can calculate the minimum amount you need to fund the account. If you are interested in the cost of other services, you can also find them on the pricing page.
