How do I know which variant is suitable for me?

You can know the suitable variant by the volume of monthly withdrawals from your MyBusiness account. If total withdrawal in a month from your account is usually less than or equal to N5m, then Bronze is for you. If total withdrawal is within N5m and not more than N10m, then Silver is for you. If total withdrawal is usually over N10m but not more than N40m, then Gold would be for you.
