Balance and Credit

Description

There are two fields that describe the money situation for the user: balance and credit.

• Balance is the amount of money you owe the user.
• Credit is the amount of money you allow the user to be in debt to you.

The balance can be increased or decreased using Manual Payments

Credit can be increased or decreased in Users' Details.

These fields act differently and have a slightly different meaning for postpaid and prepaid users.

Postpaid users

The balance can be any value:

• < 0 – the user owes you money for your services. He will get an invoice at the end of the month, and when he pays that invoice, his balance will increase.
• > 0 – the user has overpaid you (you owe the user).
• == 0 – nobody owes anything to anyone (this is usual when the user is new or has just paid his invoice and has not yet made further calls or used other services).

Credit for a postpaid user can be:

• > 0 – the user can make calls and use other services until he reaches credit, e.g. if his credit = 10 USD, he can make calls (and use other services) to a total amount of 10 USD. His balance starts at 0 and goes down to -10 USD. When the balance reaches -10 USD, the user will not be able to make any more calls.
• == ∞ - the user can make unlimited calls and use any service without restriction. All the charges will be included in the invoice.

Prepaid users

The balance for prepaid users should ALWAYS be more then zero. Otherwise, the prepaid user will be unable to dial-out.

Credit for prepaid users is ALWAYS zero.

Note: balance and credit are set for users, not devices. For example, if a user has several devices and his balance/credit does not allow him to make any more calls, he will be unable to use any of his devices.
