Billing Period

Defines the frequency of generating xDR reports for this vendor.

Offset Balance with Customer

Defines the customer for automatically offsetting the vendor’s balance (if this vendor also sends you traffic, i.e. he is also your customer). You may only choose a reseller or retail customer defined with the same currency.

This indicates that this vendor and the referenced customer represent two sides of the same company. When the billing engine processes a call from this customer and calculates the routing, it automatically excludes this vendor from the routing list to prevent a possible routing loop (sending calls back to the originator).

Minimum Amount to Offset

When the balances of both the vendor and the associated customer reach the threshold value, PortaBilling® chooses the lesser of two balances and decreases both customer’s and vendor’s balances by this amount.

Let’s consider the example for when the Minimum Amount to Offset is set to $100 and you start sending traffic to this company (to vendor) and it starts sending traffic to you (as customer)

• While the vendor’s balance is $80 and the customer’s balance is $40 – nothing happens.

• Even when the vendor’s balance crosses the threshold and becomes $120 and the customer’s balance is $80 – nothing happens.

• Only when the vendor’s balance is $140 and the customer’s balance is $105 (both balances over the threshold) – does PortaBilling® make a $105 offset.

• The vendor’s balance becomes $35 and the customer’s balance becomes $0.

The xDR records for both the vendor and the customer are created for this transaction.
